Pregnancy Nutrition Support

Pregnancy is a season of constant change - physically, emotionally, and nutritionally.

Scroll down to explore each trimester and what often comes with it - from the early waves of fatigue and food aversions, to second-trimester changes, and the final stretch of preparing for labour and breastfeeding. This space is here to meet you where you are.

There’s a lot of information on this page - and while some points may feel repeated, it’s all here to guide you through the changes of pregnancy with clarity and confidence. Dip in and out as you need. Come back when you’re ready. And remember: you don’t have to get everything perfect -nourishment is a thread you return to again and again.

This page is for general guidance only. Always follow the advice of your doctor, midwife, or registered dietitian for personalised support.

Pregnancy brings constant change - in your body, your energy, your needs.

At The Nourished Thread, you’ll find clear, evidence-based support to help you feel more grounded through it all.

First Trimester Nutrition

Weeks 1 to 12: Gentle Support for the Early Days of Pregnancy

The first trimester of pregnancy spans from week 1 to week 12, beginning from the first day of your last menstrual period. For many, it’s a time filled with mixed emotions - excitement, anxiety, and often, a surprising number of physical changes.

The first trimester often feels less like glowing and more like getting through the day. Between nausea, food aversions, exhaustion, and the emotional weight of early pregnancy, eating well can feel impossible - and that’s okay.

At this stage, the focus isn’t on eating “perfectly,” but rather staying nourished and hydrated in ways that feel manageable. A few bites here and there do add up - and supporting your energy, blood sugar, and key nutrients makes a difference even when appetite is low.

  • Finding out you’re pregnant can come with a flood of emotions - and questions. One of the first concerns many have is: What can I still eat safely?

    Foods to Include for Foundational Support:

    Even if you're feeling nauseous or low on energy, aiming for a few small, nourishing meals and snacks each day can make a big difference. These food groups provide the key nutrients needed to support early fetal development and maintain your own strength and wellbeing.

    Fruit & Vegetables

    • Rich in vitamins, antioxidants, and fibre to support digestion and immunity

    • Include a variety of colours - e.g. spinach, carrots, red peppers, blueberries, bananas

    • Fresh, frozen, or tinned (in water or 100% juice) are all equally nutritious

    • Lightly steam or roast vegetables if raw options feel too harsh on the stomach

    Wholegrains

    • Provide complex carbohydrates for steady energy and fibre to reduce constipation

    • Examples: oats, wholegrain bread, brown rice, barley, bulgur, whole wheat pasta, quinoa

    Lean Protein Sources (Aim for a source at most meals)

    • Essential for fetal tissue development and blood sugar stability

    • Options: eggs (fully cooked), lentils, beans, tofu, chicken, turkey, lean beef, or white fish

    • Try pairing with carbs (e.g. toast and scrambled eggs) to ease nausea and maintain energy

    Dairy or Fortified Alternatives

    • Provide calcium, iodine, and B12

    • Includes milk, yogurt, hard cheeses, or fortified plant-based options like soya milk/yogurt (shake these well to mix in the added calcium)

    • Choose unsweetened and calcium-fortified alternatives where possible

    Healthy Fats

    • Needed for baby’s brain development and to help absorb fat-soluble vitamins (A, D, E, K)

    • Include: avocado, olive oil, nut butters, walnuts, seeds (like chia or flax), and oily fish (e.g. salmon)

    Hydration

    • Water is best - aim for 35mls/kg body weight/day

    • Include options like ginger or peppermint tea (safe for pregnancy), low-fat milk, or coconut water

    • Avoid sugar-sweetened drinks, fizzy drinks and excess fruit juice to reduce bloating and sugar spikes

  • When you first find out you’re pregnant, it’s common to hear the phrase “you’re eating for two” — but this is a myth. In reality, your energy needs don’t increase during the first or second trimester.

    For most people, extra calories are only needed in the third trimester, and even then, it’s only about 200 extra calories per day — roughly the equivalent of a small, nutritious snack such as yoghurt with fruit and nuts, a slice of wholegrain toast with nut butter, or a small smoothie.

    If you’re very active, underweight, or carrying multiples, your energy needs may be higher, but this should be discussed with your doctor, midwife, or registered dietitian to tailor recommendations to your situation.

    The focus in early pregnancy should be on quality, not quantity — prioritising nutrient-dense foods that support your health and your baby’s development, rather than simply increasing portion sizes.

  • 🧀 Dairy & Eggs

    Avoid:

    • 🥛 Unpasteurised milk and cheeses, including soft mould-ripened cheeses such as:

      • Brie

      • Camembert

      • Chèvre (goat’s cheese)

      • Blue-veined cheeses (e.g. Roquefort, Gorgonzola)
        These can carry Listeria monocytogenes, which can cause listeriosis — a rare but serious infection during pregnancy.

    • 🥚 Raw or undercooked eggs, unless they are Lion-stamped (UK) or pasteurised. This includes:

      • Homemade mayonnaise

      • Mousses

      • Hollandaise sauce

    Eat instead:

    • Hard cheeses such as cheddar, gouda, or parmesan

    • Pasteurised soft cheeses (e.g. cream cheese, ricotta, mozzarella)

    • Fully cooked eggs or those that are Lion-stamped or pasteurised.

    🍖 Meat, Fish, and Pâté

    Avoid:

    • Raw or undercooked meat, especially pork, poultry, and minced meat — due to the risk of toxoplasmosis and listeria.

    • Cured meats (e.g. salami, chorizo, prosciutto) unless cooked until steaming hot.

    • All types of pâté, including vegetable-based — high risk of listeria.

    • Liver and liver products — these are high in preformed vitamin A (retinol), which can be toxic to the baby at high levels.

    • Game meats — may contain lead shot and are not recommended.

    🐟 Fish

    Fish is a great source of lean protein and omega-3 fatty acids, which support fertility, fetal brain development, and heart health — but some types need to be avoided or limited due to mercury or food safety concerns.

    Avoid:

    • Shark, marlin, and swordfish — due to high mercury levels, which can affect your baby’s developing nervous system.

    • Raw shellfish — can increase the risk of foodborne illness.

    • Oily fish to avoid: also includes shark, marlin, and swordfish (not typical choices but sometimes found in certain cuisines).

    Limit:

    • Tuna — no more than 4 small tins per week (or 2 fresh tuna steaks) due to moderate mercury levels.

    Safe and beneficial:

    • Oily fish such as salmon, sardines, trout, and mackerel — aim for 1–2 portions per week for omega-3s.

    • Sushi made with raw fish is safe only if the fish has been previously frozen (per UK regulations).

    • Well-cooked shellfish is safe to eat (e.g. prawns, mussels, scallops) — ensure it’s piping hot.

    🧡 Vitamin A Caution

    • Avoid liver and liver products, cod liver oil, and fish oil supplements containing retinol, as these are high in preformed vitamin A (retinol), which can cause birth defects if consumed in excess.

    • Avoid topical beauty or acne products containing retinol or retinoids during preconception and pregnancy.

    • Beta-carotene (from plant sources like carrots and sweet potatoes) is safe — your body converts it to vitamin A as needed.

    🥜 Peanuts

    Before 2009, pregnant women in the UK were advised to avoid peanuts to reduce allergy risk. However, based on a recent systematic review (RCM, 2022), there is no clear evidence that avoiding peanuts during pregnancy reduces allergy risk.
    👉 If you don’t have a peanut allergy yourself, there’s no need to avoid them — they can be a nutritious source of protein and healthy fats.

    🧂 Iodine

    Iodine supports thyroid function, fertility, and fetal brain development.

    • Recommended intake: around 200 µg/day during preconception and pregnancy.

    • Food sources:

      • 500 mL/day of cow’s milk provides roughly 350 µg/L, so can make a major contribution to intake.

      • Fortified plant milks vary: 1000 mL/day provides around 130–250 µg, depending on the brand.

      • Cheese, yoghurt, eggs, and fish also provide iodine.

    • Most individuals who regularly consume dairy, fish, and/or eggs meet iodine needs through diet, so routine supplementation is not always required.

    • Be cautious with iodine supplements — excess intake can affect thyroid function, so stick to recommended levels and avoid unnecessary high doses.

    Caffeine

    High caffeine intake has been linked to increased miscarriage risk, so it’s best to limit to 200 mg per day, roughly equivalent to:

    • 1 mug of brewed coffee (140–180 mg)

    • 2 cups of tea (50–75 mg per cup)

    Other sources to consider: green tea, cola, energy drinks, and chocolate.

    Approximate caffeine content:

    • Instant coffee (1 tsp): ~100 mg

    • Filter coffee (1 mug): 140–180 mg

    • Black tea (1 cup): 50–75 mg

    • 50 g dark chocolate: ~25 mg

    🍷 Alcohol

    There is no known safe level of alcohol during pregnancy, especially in the first trimester.
    The safest approach is to avoid alcohol completely to reduce the risk of miscarriage, developmental issues, and fetal alcohol syndrome.

    🌿 Herbal Teas & Natural Products

    Herbal products may seem gentle or “natural,” but not all are safe during pregnancy. Some can stimulate the uterus, affect hormone levels, or simply haven’t been studied enough.

    NHS guidance:

    • Limit herbal teas to no more than 4 cups per day; 1–2 cups daily is a general rule.

    • Herbal teas like ginger, lemon balm, and rose hips are generally considered safe in moderation.

    • Use caution with chamomile and raspberry leaf, especially in the first trimester.

    Avoid the following herbs, especially in the first trimester:

    • Liquorice root — can raise blood pressure and affect hormone levels.

    • Dong quai, black cohosh, blue cohosh — can stimulate uterine contractions.

    • Raspberry leaf — traditionally used to tone the uterus; best avoided until the third trimester, and only under guidance.

    Other considerations:

    • Essential oils and herbal supplements should only be used under the guidance of a qualified health professional.

    • “Detox” or weight-loss teas are not recommended.

    • If in doubt, consult your GP, midwife, or registered dietitian before taking any herbal product — even over the counter.

  • If you were taking preconception or fertility supplements, it’s important to reassess once you find out you’re pregnant. Nutritional needs shift quickly, and your prenatal should match these changes.

    Key Nutrients to Prioritise in the First Trimester:

    • Folate (Folic Acid or Methylfolate): Essential for neural tube development, which forms your baby’s brain and spine. Aim for 400–600 mcg per day. Most prenatals contain either folic acid or the active form, methylfolate - check the label to ensure your supplement meets this requirement.

    • Vitamin D: supports bone health, immune function, and plays a role in fertility and pregnancy outcomes.

      • In the UK, the standard recommendation is 10 µg (400 IU) of vitamin D daily throughout pregnancy (and when trying to conceive), particularly during the autumn and winter months when sunlight exposure is limited.

        International guidelines (e.g. some in North America and parts of Europe) recommend higher doses — up to 25 µg (1,000 IU) per day — especially in populations at risk of deficiency.

      If you have darker skin, limited sun exposure, cover your skin for cultural or medical reasons, or live at higher latitudes, you may benefit from the higher end of this range. Speak with your healthcare provider for personalised advice.

    • Vitamin B12: Important for red blood cell formation and your baby’s neurological development. You’ll need 2.6 mcg per day, especially if you follow a vegetarian or vegan diet. Look for it in your prenatal or consider a separate supplement if needed.

    • Vitamin B6: Can help ease nausea in early pregnancy. Many prenatals include this, but it can also be taken separately up to 25 mg per day if recommended by your provider.

    • Iodine: Recommended intake around 200 µg/day during preconception and pregnancy, can be got from your diet rather than supplements -

      Food sources:

      • 500 mL/day of cow’s milk provides roughly 350 µg/L, so can make a major contribution to intake.

      • Fortified plant milks vary: 1000 mL/day provides around 130–250 µg, depending on the brand.

      • Cheese, yoghurt, eggs, and fish also provide iodine.

      Most individuals who regularly consume dairy, fish, and/or eggs meet iodine needs through diet, so routine supplementation is not always required.

      Be cautious with iodine supplements — excess intake can affect thyroid function, so stick to recommended levels and avoid unnecessary high doses.

    • Iron: Needed for your growing blood volume and to transport oxygen efficiently. The recommended amount is 10–27 mg per day, but some people find iron worsens nausea. If this is the case, speak with your dietitian or GP about gentler forms like iron bisglycinate. Always take iron with food, not on an empty stomach.

    • Choline: A lesser-known but vital nutrient for fetal brain and spinal cord development. Not all prenatals include it, so include choline-rich foods like egg yolks, meat, and soybeans where possible.

    • Omega-3s (DHA): These healthy fats support your baby’s brain and eye development. If your prenatal doesn’t contain DHA, consider a separate supplement providing 200–300 mg per day, especially if you don’t regularly eat oily fish.

    Note: These recommendations may not vary too far from the contents of your preconception supplement. Compare the nutrition label on your current multivitamin before switching - it may not be necessary to purchase something entirely new. Instead, you might simply need to adjust or add individual supplements to fill any nutritional gaps. Always discuss with your doctor, midwife, or registered dietitian if you’re unsure.

  • If you were taking a preconception or fertility supplement, it's important to review and potentially update your supplement routine once you find out you're pregnant.

    What to Check:

    • Prenatal multivitamin: Most people should switch to a dedicated prenatal supplement that is specifically formulated to meet the nutritional needs of pregnancy - not just fertility.

    • Key nutrients to look for in your prenatal:

      • Folic acid or methylfolate (400–600 mcg)

      • Vitamin B12 (2.6 mcg)

      • Vitamin D (10 mcg or 400 IU - 25mcg)

      • Choline (ideally included, though not always present)

      • Optional: Omega-3s (200–300 mg DHA if not eating oily fish 1–2x/week)

    • Discontinue any fertility-specific or high-dose fertility supplements (e.g. high levels of CoQ10, inositol, DHEA) unless your healthcare provider has advised you to continue.

    • Avoid any supplement that includes high doses of retinol (vitamin A) or high-dose herbal blends, The NHS advises that pregnant women should not exceed 700 micrograms (µg) of vitamin A daily from all sources, including food and supplements. 

    • Continue or adjust any individual supplements based on your blood work or specific needs (e.g. extra iron, B12, or vitamin D if you were already deficient).

    Tip: Once you confirm pregnancy, review your supplement labels or bring them to your GP, midwife, or registered dietitian to ensure they’re still appropriate for this new stage.

  • During pregnancy, your immune system adapts to support your growing baby - but that also makes you more vulnerable to foodborne illnesses like listeria, toxoplasmosis, and salmonella. While the risk is small, taking a few extra precautions can help keep you and your baby safe.

    Key Recommendations:

    • Wash all fruits and vegetables thoroughly under running water, even those you plan to peel. This helps remove soil that may carry toxoplasma or other harmful pathogens.

    • Avoid pre-packed salads or bagged leafy greens unless you wash them yourself and eat them immediately. Listeria can grow at fridge temperatures and multiply if left too long.

    • Reheat all leftovers until piping hot (steaming throughout, not just warm). Avoid reheating more than once.

    • Handle raw meat carefully: Keep it separate from other foods, and wash hands, utensils, and chopping boards after contact. Cook all meat until there is no pink left and juices run clear.

    • Avoid eating cold cuts, pâtés, and deli meats unless they are cooked until hot. These items can carry listeria if not freshly prepared.

    • Be mindful with canned foods - once opened, store leftovers in a sealed container in the fridge and consume within 24 hours. Never eat directly from a can that has been opened and stored.

    • Avoid raw or lightly cooked eggs unless they are Lion-stamped (UK) or pasteurised (elsewhere).

    These steps help reduce exposure to bacteria and parasites that may be harmless to most people but could pose a greater risk during pregnancy.

  • While it may not be visible from the outside, your body is working hard behind the scenes. Hormones like hCG (human chorionic gonadotropin), estrogen, and progesterone surge, supporting embryo development and signalling your body to prepare for pregnancy. These hormonal shifts are essential - but they can also trigger a host of early pregnancy symptoms.

    • Fatigue and low energy: One of the earliest and most common symptoms. Your body is using extra energy to support the placenta and developing baby.

    • Nausea and vomiting: Often worse in the morning but can strike anytime. This is linked to rising hCG and estrogen levels.

    • Food aversions or cravings: Smells, textures, or foods you previously loved may suddenly become unappealing. On the flip side, cravings can appear too.

    • Bloating and constipation: Progesterone slows digestion to allow more nutrient absorption, but it can also lead to sluggish bowels.

    • Sore breasts: Hormonal changes increase blood flow and prepare the breasts for feeding.

    • Stuffy nose or breathlessness: Increased blood volume and hormone shifts can lead to nasal congestion and shortness of breath.

    All of this can make thinking about food - let alone eating "well" feel overwhelming. Early pregnancy isn’t the time for pressure or perfection it’s about gentle nourishment that supports both your body and baby.

    • Eat little and often – Every 2–3 hours, aim for small snacks or light meals to prevent dips in blood sugar that can worsen nausea.

    • Pair carbs with protein or fat – Toast with nut butter, rice cakes and hummus, crackers and cheese, or a small smoothie with Greek yogurt help steady energy.

    • Try cold, bland, or beige foods – Warm meals or strong smells can be triggering. Cold leftovers, fruit, plain pasta, or hard-boiled eggs may go down easier.

    • Keep bedside snacks handy – Dry toast, oatcakes, or plain cereal can help ease morning nausea before getting up.

    • Fluids matter, too – Sip between meals, not during. Try ginger tea, lemon water, coconut water, or even broths for hydration with gentle flavour.

    • Focus on “safe” foods – If all you can manage is toast or plain pasta, that’s okay for now. Trust your appetite to guide you, and know variety will return with time.

  • HG is not normal morning sickness. Ask for a referral to a dietitian for support.

    Nutrition Support When Eating Feels Impossible

    Hyperemesis gravidarum (HG) is a severe form of nausea and vomiting in pregnancy that affects about 1–3% of pregnant women. Unlike “typical” morning sickness, HG can cause persistent vomiting, dehydration, weight loss, and nutrient deficiencies, sometimes requiring medical treatment (e.g., IV fluids or hospital admission).

    Important note: If you’re struggling to keep fluids down or notice signs of dehydration (e.g., dark urine, dizziness), seek medical help immediately. HG often requires medical management alongside dietary support.

    Why Does HG Happen?

    The exact cause isn’t fully understood, but hormonal changes (like rising hCG and oestrogen levels) play a role. Women with a history of HG, multiple pregnancies, or high levels of certain hormones are more at risk.

    Nutrition Goals with HG

    The priority with HG is not about eating “perfectly” - it’s about hydration, energy preservation, and small wins with food.


    Key focuses include:

    • Preventing dehydration (sips of fluid, ice chips, oral rehydration solutions).

    • Maintaining some energy intake with small, frequent bites when possible.

    • Avoiding unnecessary restrictions - eat what you can tolerate, even if it’s not the “ideal” food.

    • Rebuilding nutrient stores gradually once symptoms ease.

    Practical Nutrition Tips

    1. Eat “Little and Often”

      • Aim for tiny, frequent snacks instead of three big meals.

      • Dry, plain foods like crackers, toast, or rice cakes may feel easier first thing in the morning.

    2. Stay Hydrated in Any Form

      • Sips of water, ice lollies, or diluted fruit juice.

      • Try cold fluids or sparkling water, which can be easier to tolerate.

      • Oral rehydration salts (like Dioralyte) can help replenish electrolytes if vomiting is frequent.

    3. Choose Easy-to-Digest Foods

      • Simple carbs (white bread, rice, plain pasta) can provide quick energy.

      • Avoid strong smells - cold foods (like chilled sandwiches or yogurt) often cause less nausea.

    4. Protein for Sustained Energy

      • Try small amounts of mild protein foods (e.g., Greek yogurt, boiled egg, plain chicken).

      • Peanut butter or nut butters can work well with toast or crackers.

    5. Ginger and Vitamin B6

      • Vitamin B6 can be recommended but doses may be individual, ask your doctor or midwife before supplementing.

      • Ginger (e.g., ginger tea, ginger biscuits, or capsules) has some evidence for reducing nausea.

    6. Don’t Worry About Food Quality in the Early Stages

      • If the only thing you can manage is plain crisps or biscuits, that’s okay. Focus on hydration and energy first - nutrition can be rebuilt later.

    Medical Support

    • HG often needs antiemetic medications e.g. Cyclizine, IV fluids, or hospital care.

    • Some women may require nutrition support via IV or feeding tubes in severe cases.

    • Your midwife or GP can arrange blood tests to monitor hydration and nutrient levels (e.g., electrolytes, B vitamins).

    When to Seek Urgent Help

    • Unable to keep any fluids down for 24 hours.

    • Signs of severe dehydration (e.g., very dark urine, confusion, extreme fatigue).

    • Rapid weight loss.

    Emotional Wellbeing and HG

    HG can be mentally exhausting. Fatigue, isolation, and guilt about “not eating well” are common. Remember: none of this is your fault. Nutrition goals during HG are about survival, not perfection.

  • Sluggish bowels are common in pregnancy - progesterone slows digestion, your iron supplement might be adding to it, and if you’re not eating as regularly, fibre intake might be lower.

    • Hydrate well: Aim for at least 1.5–2L of fluids daily. Warm drinks, water with lemon, or gentle teas (e.g. ginger, peppermint) can help stimulate movement.

    • Include fibre from a variety of sources:

      • Soluble fibre: oats, flaxseeds, chia seeds, cooked veg, lentils

      • Insoluble fibre: wholegrain breads, wholegrain or wholewheat pastas and rice, wheat bran, raw veg, skins of fruits

    • Pair fibre with fluids: Fibre needs water to work - otherwise, it can worsen bloating.

    • Prune juice (small glass daily) or a small serving of apple sauce or cooked apples may help gently stimulate bowel movements.

    • Movement: Gentle walks after meals can support digestion and bowel function.

    • Check your iron supplement: Iron bisglycinate is a gentler form that may reduce constipation risk. Ask your doctor or dietitian about switching if needed.

    • Slowing down your eating, sipping peppermint tea, and avoiding overly greasy or fried foods can help with bloating.

  • The first trimester is like running a marathon while growing a new organ (the placenta!) - no wonder you’re tired. Blood sugar dips, poor sleep, and nausea can all contribute.

    • Don’t skip meals: Even if you're nauseous, aim for small, frequent meals or snacks every 2–3 hours.

    • Include complex carbohydrates at each meal:

      • Examples: oats, wholegrain toast, brown rice or pasta, quinoa, sweet potatoes, wholewheat crackers

      • These provide a steadier source of energy than refined sugars e.g. sweets, biscuits, crisps, sweet breakfast cereals.

    • Always pair carbs with protein or healthy fat to stabilise blood sugar and prolong energy:

      • Rice cakes + hummus or nut butter

      • Wholegrain toast + nut butter or cheese

      • Crackers + cheese

      • Smoothie with yogurt or protein powder

      • Yogurt + fruit or granola

    • Protein goal: Aim for 1g protein per kg of body weight/day in pregnancy. This helps with energy, growth, and managing cravings.

    • Don’t overdo caffeine: It might feel like a fix for fatigue but stay under 200mg/day and focus more on nourishing meals and rest where possible.

    • Don’t underestimate the power of a 20-minute nap.

  • What to expect, especially in the first trimester

    It’s completely normal to feel uncertain - or even anxious - about changes in your body during pregnancy, especially around weight. Let’s start by saying this: your body is doing something incredible. And weight gain is a natural and important part of supporting both you and your growing baby.

    Weight Gain by Trimester: What to Expect

    Ranges do exist but they are not strict targets - they’re guides to help ensure both you and baby are supported through each stage of pregnancy. Every body is different, and what’s “normal” for you may look different from someone else’s journey.

    Every body grows differently, and the numbers don’t define your health or how well you’re supporting your baby.

    • 1st Trimester (Weeks 1–12):
      You may gain little or no weight (about 1–2 kg / 2–4.5 lbs), especially if dealing with nausea or appetite changes. Some weight loss is also common if morning sickness is severe.

    • 2nd Trimester (Weeks 13–27):
      This is when most steady weight gain begins. You may gain about 0.4–0.5 kg (1 lb) per week as your appetite improves and your baby’s growth accelerates.

    • 3rd Trimester (Weeks 28–40):
      Your baby is gaining weight rapidly, and your body is building reserves for birth and breastfeeding. Expect similar weekly gains as in the second trimester.

    Some body’s may gain more than these numbers, and that is okay - weight gain reflects remarkable physiological changes happening inside your body. Every kilogram gained serves a purpose:

    • Your baby: ~3–4 kg

    • Placenta: ~0.7 kg

    • Amniotic fluid: ~1 kg

    • Increased blood volume: ~1.5–2 kg

    • Breast tissue and fat stores (to prepare for breastfeeding): ~3–4 kg

    • Uterus growth: ~1–2 kg

    • Increased body fluids (between cells): ~1–1.5 kg

    • Organ adaptations: Your heart grows larger and pumps more blood to support your baby, while your kidneys and liver also work harder, adjusting to new demands.

    All of this is your body intelligently adjusting to grow, nourish, and sustain another life - and to prepare you for labour, birth, and recovery.

    If You're Feeling Anxious

    Pregnancy changes can stir up complex feelings about body image - especially if you’ve previously struggled with weight or food-related concerns. You're not alone. Try to focus on how you feel, not just how you weigh. Nourishment, rest, and movement matter more than numbers.

    A few tips:

    • Focus on nutrient-dense meals that support energy and digestion

    • Avoid obsessively tracking weight - let your midwife or doctor guide any concerns

    • Gentle movement (like walking, stretching, yoga) can support mental and physical well-being

    • Speak with a registered dietitian if weight changes are emotionally difficult

  • Nourishment for You and Your Smile

    Pregnancy changes almost every part of your body - and your mouth is no exception. Hormonal shifts can make gums more sensitive and prone to bleeding (known as pregnancy gingivitis), while nausea, vomiting, and changes in appetite can affect oral health. Good dental care, combined with balanced nutrition, supports not only your teeth and gums but also your overall wellbeing during pregnancy.

    Why Oral Health Matters in Pregnancy

    • Increased progesterone and oestrogen can make gums more prone to inflammation, swelling, and bleeding.

    • Frequent morning sickness or acid reflux can expose teeth to stomach acid, increasing the risk of enamel erosion.

    • Cravings for sweet or acidic foods (like citrus or fizzy drinks) can also impact tooth health if consumed often.

    • Gum disease has been linked to higher risks of pregnancy complications (like preterm birth), so prevention is key.

    Nutrition Tips for Healthy Teeth & Gums

    • Calcium-rich foods: Milk, yogurt, cheese, and fortified plant-based milks help strengthen teeth and bones.

    • Vitamin D: Supports calcium absorption and gum health - oily fish, eggs, fortified foods, or supplements (10 mcg/day is recommended in pregnancy).

    • Vitamin C: Found in oranges, peppers, and strawberries, it helps keep gums healthy and reduces inflammation.

    • Limit sugary snacks and drinks: If you’re craving sweet foods, opt for natural sweetness like fruit paired with yogurt or nut butter.

    • Stay hydrated: Water helps wash away bacteria and neutralise acids in your mouth.

    Practical Tips If You’re Nauseous or Vomiting

    • Avoid brushing your teeth immediately after vomiting - acid softens enamel and brushing too soon can wear it down.

    • Keep soft, mild foods on hand (e.g., yogurt or plain toast) to ease discomfort after vomiting.

    Daily Dental Care Routine

    • Maintain good at-home cleaning habits, as consistent brushing and flossing are the best defences against pregnancy gingivitis and plaque build-up.

    • Book a routine dental check-up during pregnancy - NHS dental care is free during pregnancy and up to 12 months postpartum (UK-based benefit).

Second Trimester Nutrition

Weeks 13 to 27: Building Strength, Supporting Growth

The second trimester - from week 13 to week 27 - is often referred to as the "golden trimester." For many, early symptoms like nausea and fatigue begin to ease, and energy levels return. It’s also when the physical signs of pregnancy become more visible, and nutritional demands begin to rise.

This stage marks a period of rapid fetal growth, organ development, and increased blood volume. Your baby’s skeleton begins to harden, taste buds form, and the brain and nervous system continue developing. Meanwhile, your body is working hard to support the placenta, uterus, and growing baby - which means your calorie, protein, iron, and calcium needs increase.

    • Increased appetite and energy levels as nausea fades

    • Heartburn or reflux, especially as the uterus expands upward

    • Constipation due to slower digestion and pressure on the bowels

    • Leg cramps or restless legs, often related to low magnesium or fluid imbalance

    • Feeling short of breath as your uterus expands and hormone levels rise

    You may also notice an increased interest in preparing for your baby’s arrival - physically and emotionally. Nutrition in this phase is about meeting increased needs, while staying comfortable and supported.

  • Below are common second trimester symptoms - and gentle, food-first ways to support your body through them.

    Reflux, Food Aversions, and Gentle Swaps

    As your uterus expands, it can put pressure on your stomach and digestive tract, increasing the likelihood of heartburn and reflux. If certain foods trigger discomfort, you don’t need to force them - simply find gentle alternatives that meet your nutritional needs:

    • Avoiding milk due to reflux? Try calcium-rich Greek yogurt, kefir, or calcium-fortified plant-based milks like oat or soy.

    • If protein feels too heavy: Try scrambled eggs, lentil soup, smoothies with nut butter, or blended tofu in sauces.

    • Finding veggies hard to digest? Go for well-cooked options like mashed sweet potato, roasted carrots, or vegetable soups.

    • Triggered by smells? Cold meals like sandwiches, chilled pasta salad, or overnight oats may be easier to tolerate than hot meals.

    Cravings

    Cravings are normal and incredibly common in the second trimester - they’re your body’s way of communicating shifting energy needs and hormone levels. There's no shame in wanting a specific food (or several!). The goal isn’t to suppress cravings, but to meet them in a nourishing way:

    • Sweet cravings? Try fruit with nut butter, Greek yogurt with berries, or frozen banana blended with cocoa.

    • Salty cravings? Opt for popcorn with olive oil, nuts, or a few olives or pickles.

    • Ice cravings or odd textures? Known as pica, this can signal low iron - speak with your provider if you’re craving non-food items like ice, chalk, or soil.

    Dysgeusia (Metallic Taste)

    That strange metallic taste in your mouth (dysgeusia) is common during pregnancy and often due to hormonal changes. It can affect how food tastes or even reduce your appetite. To manage it:

    • Sip citrus-infused water (e.g. lemon, orange slices)

    • Try cold meals and sharp flavours like pickles, vinegar-based dressings, or sour fruit

    • Try eating with plastic cutlery.

    Skin Changes & Hydration

    As your body stretches to accommodate your growing baby, you may notice drier skin, stretch marks, or itchiness, especially around your belly and breasts.

    • Focus on hydrating foods like cucumber, watermelon, soups, and smoothies to boost fluid intake from within

    • Healthy fats - including avocado, flaxseeds, olive oil, and oily fish - help nourish your skin’s elasticity

    • Aim for 1.5–2 litres of water or safe herbal teas per day. Sip consistently rather than guzzling large amounts at once.

    While stretch marks are often genetic, supporting skin from the inside out with hydration and nutrition may help improve skin resilience and reduce discomfort.

    Breast Development & Nutrient Storage

    Your breasts are already preparing for their post-birth role: feeding your baby. During the second trimester, your body begins storing nutrients and developing breast tissue, laying the foundation for milk production.

    Support this process by prioritising:

    • Protein: Eggs, beans, poultry, tofu, yogurt - aim for protein at every meal

    • Healthy fats: Nuts, seeds, olive oil, oily fish - essential for tissue development and hormone balance

    • Calcium & Magnesium: Needed for breast tissue development and future milk supply

      • Calcium: milk, yogurt, cheese, fortified plant milks, leafy greens

      • Magnesium: pumpkin seeds, dark chocolate, wholegrains, spinach

    Monitoring Iron & Blood Work

    Around 20–28 weeks, your midwife or doctor will usually check your hemoglobin and ferritin (iron stores) to assess how your body is coping with the increased blood volume.

    • Low iron? You may feel tired, dizzy, breathless, or notice pale skin.

    • What to do:

      • Focus on iron-rich meals: red meat, lentils, spinach, pumpkin seeds

      • Pair with vitamin C-rich foods (e.g. orange, bell peppers) to enhance absorption

      • Avoid drinking tea or coffee with meals, as they reduce iron absorption

      • Ask about iron supplements - forms like ferrous bisglycinate are often gentler on digestion

    A dip in energy is normal in pregnancy - but if it’s affecting your quality of life, don’t hesitate to bring it up at your next check-in.

  • Energy & Calorie Needs

    In the second trimester, your daily energy needs increase by approximately 300–350 kcal/day. This equates to:

    • A small extra meal or

    • Two nourishing snacks - e.g. oatcakes with hummus and cucumber, or Greek yogurt with banana and seeds.

    Why this matters: This additional energy supports the growing baby, expanding uterus and placenta, and increased maternal metabolism.

    Note: This is not “eating for two.” Your needs grow moderately, and nutrient density is more important than calories alone.

    Practical Nutrition Tips

    • Eat every 3–4 hours
      Helps maintain steady blood sugar, curb fatigue, and support fetal growth.

    • Balance each meal
      Include a mix of complex carbohydrates, protein, and healthy fats - e.g. a veggie omelette with wholegrain toast and avocado.

    • Increase fibre
      To prevent or relieve constipation, incorporate oats, beans, lentils, wholegrain bread, fruit with skin, and vegetables daily.

    • Stay hydrated
      Drink at least 6–8 glasses per day - including water, milk, or safe herbal teas. Hydration supports digestion, energy, and blood volume.

    • Prioritise digestion-friendly meals
      Lighter, well-cooked foods and avoiding large meals close to bedtime can help manage reflux, which is common during this trimester.

    Key Nutrients to Prioritise

    Iron

    • Role: Supports increased maternal blood volume and helps oxygen transport to the baby.

    • Needs: ~27 mg/day (BDA, NHS)

    • Food sources: Red meat, lentils, eggs, fortified cereals, spinach, tofu

    • Tips:

      • Boost absorption with vitamin C (e.g. pair spinach with peppers or orange slices).

      • Gentler iron forms like bisglycinate may reduce constipation or nausea.

      • If iron levels are borderline or low, your healthcare provider may suggest a supplement.

    Calcium

    • Role: Essential for fetal bone, teeth, and muscle development, and maternal bone preservation.

    • Needs: ~1000 mg/day (NHS)

    • Food sources: Milk, yogurt, cheese, fortified plant-based milks (check for calcium + vitamin B12), broccoli

    • Note: Most prenatal vitamins in the UK do not contain enough calcium, so aim to meet needs via food or consult a dietitian for a supplement recommendation.

    Vitamin D

    • Role: Supports bone health by regulating calcium and phosphate absorption.

    • Needs: 10 mcg/day (400 IU) as a supplement (recommended by the NHS for all pregnant individuals)

    • Sources: Limited in food - oily fish, fortified spreads/cereals.

    • Supplementation is strongly advised, especially during autumn/winter or for those with darker skin or limited sun exposure.

    Omega-3s (DHA)

    • Role: Crucial for fetal brain and eye development.

    • Needs: ~200–300 mg/day of DHA

    • Sources: Oily fish (salmon, mackerel, sardines), algae-based supplements (for vegetarians/vegans)

    • Tip: If you’re not eating 1–2 portions of oily fish/week, consider a DHA supplement — many prenatals do not include it.

    Magnesium

    • Role: Supports muscle relaxation, sleep, and may ease cramps or restless legs.

    • Sources: Pumpkin seeds, almonds, dark leafy greens, whole grains, legumes, dark chocolate

    • Consider: If experiencing cramps or poor sleep, magnesium from food or a supplement (if advised) may help.

    Protein

    • Role: Supports the development of fetal tissues (muscle, organs) and maternal tissues (breast, uterus, blood).

    • Needs: ~80-90 g/day (individual needs vary with body size)

    • Sources: Poultry, eggs, dairy, lentils, beans, tofu, fish, nuts, seeds, and fortified plant alternatives

    • Tip: Include protein at each meal and snack for optimal balance and energy.

  • Continue your prenatal multivitamin from the first trimester if it:

    • Includes folic acid or methylfolate (400–600 mcg)

    • Check for vitamin D 10-25mcg/day, vitamin B12

    • Do not supplement with iron or iodine unless there is a need to. Ask your health professional.

    • If calcium or DHA are not included, assess your intake via food or add separate supplements if needed.

    • Avoid doubling up - check labels before combining products.

    Always consult your midwife, doctor, or registered dietitian before adding new supplements, especially if managing iron or vitamin D levels.

  • Between 24 and 28 weeks, many people are offered a Glucose Tolerance Test (GTT) - a standard screening to check how your body is managing blood sugar. It helps identify gestational diabetes (GDM), a type of diabetes that can develop during pregnancy.

    What to expect:
    The test involves drinking a sweet glucose drink after an overnight fast, followed by one or more blood draws over a few hours to measure how your body processes sugar. It’s safe for you and your baby, and it doesn’t mean anything is wrong - it’s simply a routine check.

    Do you need to prepare?
    No special diet changes are needed before your GTT. In fact, trying to “eat clean” in the days leading up to the test won’t change the outcome - and might even make it harder to catch signs of GDM early, when support is most effective. Just follow the instructions your midwife or doctor gives you, including fasting if required.

    If you’re diagnosed with GDM, you’re not alone. It can feel overwhelming at first, but it’s manageable - and with the right support, you can feel confident and in control. Keep reading further down the page for practical, evidence-based guidance on managing gestational diabetes through nutrition, meal planning, and lifestyle tips.

Gestational Diabetes (GDM)

Understanding, screening, and nutrition support

Gestational diabetes (GDM) is a form of diabetes that develops during pregnancy - most often in the second or third trimester - and typically disappears when baby is born. It’s caused by hormonal shifts from the placenta that reduce your body’s sensitivity to insulin, the hormone that helps move sugar out of your blood and into your cells for energy. This natural increase in insulin resistance is a normal part of pregnancy - but for some, the body can’t keep up, and blood glucose levels rise higher than they should.

It’s important to know: GDM is not your fault. It doesn’t mean you’ve done anything wrong - it can affect anyone, even those who eat well, exercise regularly, and have no underlying health concerns.

  • While GDM can happen in any pregnancy, certain factors can increase your likelihood:

    • A BMI over 30 before pregnancy

    • A family history of type 2 diabetes

    • A personal history of polycystic ovary syndrome (PCOS)

    • Having previously had a baby over 4.5kg (10 lbs)

    • A previous pregnancy with GDM

    • Certain ethnic backgrounds (e.g. South Asian, Black, Middle Eastern)

    • Being over age 35

    Even with no risk factors, some people will still develop gestational diabetes. That’s why screening - whether routine or risk-based - plays an important role in identifying and managing it early.

  • GDM is usually temporary and resolves after your baby is born. But it’s still important to monitor and manage it because:

    • It can increase the risk of large birth weight (macrosomia), which may lead to delivery complications

    • It may raise the chance of preterm birth or neonatal low blood sugar (hypoglycaemia)

    • If unmanaged, it slightly increases the chance of stillbirth, though this is rare

    • It raises the future risk of type 2 diabetes for both mum and baby - making early management key for long-term health

    The positive news? With dietary guidance, lifestyle changes, and support, most people with GDM go on to have healthy pregnancies and births.

  • Screening practices vary depending on where you live, for example:

    • Ireland: Not all pregnant women are screened. GDM testing is typically offered if you have risk factors, such as a BMI over 30, a family history of type 2 diabetes, previous GDM, or a baby weighing over 4.5kg at birth.

    • UK: The NHS follows a similar risk-based approach. If you're considered at risk, you're usually offered a glucose tolerance test between 24–28 weeks.

    • Bermuda & United States: Screening is routinely offered to everyone, usually between 24–28 weeks, using the Oral Glucose Tolerance Test (OGTT).

    What is the OGTT?

    The Oral Glucose Tolerance Test (OGTT) is a safe and widely used screening tool to diagnose GDM.

    Here’s how it works:

    1. You fast overnight (8–12 hours).

    2. A blood sample is taken to check your fasting glucose level.

    3. You drink a glucose solution (usually 75g in UK/Ireland or 100g in the US).

    4. Further blood samples are taken at 1 and 2 (or 3) hours after drinking to see how your body processes sugar.

    Results are interpreted differently depending on the country.

    You may be diagnosed if one or more of your results are elevated.

    The test is harmless to you and your baby, but it may cause temporary nausea or lightheadedness for some people due to the high sugar content.

    Alternatives to the OGTT

    While the OGTT remains the standard, some women are choosing non-traditional screening routes, especially if they have concerns about the test or previous negative experiences.

    One emerging approach (used in some clinics and with midwife-led care) involves self-monitoring blood glucose levels at home over a 5–7 day period. This typically includes:

    • Fasting glucose each morning

    • Readings 1–2 hours after meals

    • A food log to help interpret patterns

    These readings are reviewed by your midwife, doctor, or dietitian. While not formally recommended in all national guidelines, it may be a suitable alternative in specific contexts, especially when supported by a qualified healthcare team. Always consult your care provider before choosing an alternative to OGTT.

  • If you’re diagnosed with GDM, nutrition is the first-line approach to managing blood glucose levels.

    Working with a registered dietitian can help you:

    • Understand how different foods impact your blood sugar, the focus is usually on your total carbohydrate intake

    • Create balanced meals that keep levels stable

    • Learn how to space out carbohydrates, incorporate protein and fibre, and prevent spikes

    • Monitor portion sizes and read labels with confidence

    • Adjust meals to your personal preferences, culture, and appetite

    Many people with GDM are able to manage it through diet and lifestyle alone, though some may need medication or insulin if blood sugar targets aren’t met.

    • Balance carbohydrates: Spread them throughout the day in regular meals/snacks. Avoid very large portions of carbs at one sitting.

    • Pair carbs with protein or healthy fats: e.g. wholemeal toast + egg or Greek yogurt + berries

    • Choose high-fibre, slow-release carbs: e.g. oats, lentils, quinoa, sweet potato, seeded bread

    • Limit sugary drinks and refined snacks: These can cause sharp glucose spikes

    • Stay active: Even gentle walks after meals can help lower post-meal blood glucose

    Blood sugar monitoring helps you and your healthcare team personalise your care and make adjustments as needed. Access to monitoring tools and guidance on how to use them can vary depending on your location and healthcare provider.

  • The Oral Glucose Tolerance Test (OGTT) is an important screening tool for gestational diabetes, but it can leave some people feeling a bit off afterwards — especially if you’ve fasted overnight and then had a concentrated glucose drink. It’s common to feel tired, lightheaded, nauseous, or even headachey once the test is complete.

    Here are some gentle, practical ways to help your body recover and feel better:

    1. Take a Gentle Walk

    Once your test is finished and you’re free to leave, a 10–15 minute light walk can help stabilise blood glucose levels and boost circulation. Even a slow stroll or walking around the clinic car park can make a difference.

    2. Eat a Balanced Meal or Snack

    After fasting and a large sugar load, your blood glucose may dip, making you feel shaky or ravenous. Replenish with a balanced meal or snack that includes:

    • Protein (e.g. eggs, Greek yoghurt, lean meat, tofu)

    • Fibre-rich carbohydrates (e.g. wholegrain toast, oats, fruit)

    • Healthy fats (e.g. avocado, nuts, seeds)

    For example, try scrambled eggs on wholegrain toast with sliced avocado, or Greek yoghurt with berries and a sprinkle of nuts.

    3. Rehydrate

    Drink plenty of water throughout the rest of the day. This can help flush out excess glucose, support digestion, and reduce headaches.

    4. Rest if You Need To

    It’s normal to feel a little tired after the OGTT, especially if you had to sit still for a couple of hours. If possible, schedule lighter activities for the rest of the day and allow yourself some downtime.

    5. Listen to Your Body

    Everyone responds differently to the test. Some people feel completely fine, while others may feel drained or “off” for a few hours. Trust your body’s signals and give it what it needs — whether that’s food, movement, or rest.

    6. Follow Up

    Your healthcare provider or midwife will review your OGTT results and let you know the next steps. If your result is positive for gestational diabetes, you’ll be referred to a specialist team for guidance on nutrition, monitoring, and management.

    💡 Tip: If you know you’re prone to nausea or blood sugar dips, bring a balanced snack with you to eat as soon as the test finishes — this can make a big difference in how you feel.

Third Trimester Nutrition

Weeks 28 to Birth: Nourishment for the Final Stretch

The third trimester - weeks 28 to 40 (or whenever baby decides to arrive) - is a time of anticipation, growth, and preparation. Your baby is gaining weight rapidly, their brain and lungs are maturing, and they’re storing up essential nutrients like iron and calcium for life outside the womb. Meanwhile, your body continues to adapt to meet these growing demands, which can sometimes mean more fatigue, discomfort, or digestive changes.

Your nutritional focus now is on maintaining energy, supporting fetal development, and getting ready for birth and breastfeeding. It’s also a great time to revisit your supplement needs and stay mindful of symptoms like reflux or constipation.

    • Shortness of breath as your uterus presses against your diaphragm

    • Frequent urination and broken sleep

    • Constipation or reflux from slowed digestion and pressure on organs

    • Braxton Hicks contractions - irregular tightening of the uterus

    • Pelvic heaviness or discomfort

    • Increased fatigue or disrupted sleep

    These symptoms are common, but with consistent nourishment and hydration, you can support your comfort and energy in the final stretch.

    How Nutrition Can Help

    Fatigue & Poor Sleep

    • Maintain steady blood sugar with regular, balanced meals

    • Try magnesium-rich foods like pumpkin seeds and leafy greens in the evening

    • Avoid large meals right before bed to reduce reflux and improve rest

    Constipation

    • Increase insoluble fibre from wholegrains, lentils, prunes, and pears (with skin)

    • Stay hydrated and add chia seeds or linseeds/flaxseeds to porridge or smoothies

    • Iron supplements may contribute - if constipating, speak to your midwife about switching to a gentler form like iron bisglycinate

    Heartburn / Reflux

    • Eat smaller meals more often

    • Sit upright after eating

    • Limit triggers: spicy foods, citrus, caffeine, and chocolate

    • Consider switching from iron supplements with ferrous sulfate to a gentler formulation or adjusting timing

  • Energy & Calorie Needs

    There’s a lot of conflicting information about how many extra calories you need during pregnancy. Contrary to the old saying, pregnancy is not about “eating for two.”

    Most dietitians and UK public health guidance recommend that extra energy is only needed in the third trimester, and even then, it’s around 200 extra calories per day. This can usually be met by simply adding one nutritious snack, such as yoghurt with fruit and nuts, a slice of wholegrain toast with nut butter, or a small smoothie.

    If you’re more active than average, underweight, or carrying multiples, you may need more energy — this should be discussed with your doctor, midwife, or registered dietitian so your needs can be tailored to you.

    Focus on quality over quantity: choose nutrient-dense foods that support both your health and your baby’s growth, rather than simply increasing portion sizes of less nutritious foods.

    • Aim for slow-release, fibre-rich carbs (oats, brown rice, sweet potato) to maintain energy and prevent blood sugar crashes

    • Include a source of lean protein at every meal - this supports maternal tissue growth (e.g. uterus and breasts) and fetal development

    • Choose healthy fats (avocado, olive oil, nuts, oily fish) for energy and fetal brain growth

    • Drink 6–8 glasses of fluid daily, ideally water or caffeine-free herbal teas (peppermint and ginger are considered safe)

    Key Nutrients in the Third Trimester

    Iron

    • Why: Supports red blood cell production and prepares you for blood loss at birth

    • Recommended intake: ~27 mg/day

    • Sources: Red meat, lentils, spinach, iron-fortified cereals

    • Tip: Take iron with vitamin C-rich foods (e.g. orange juice) for better absorption. Avoid tea or coffee near iron-rich meals as tannins can inhibit uptake.

    Calcium & Magnesium

    • Why: Help build baby’s bones and prepare for lactation

    • Recommended calcium intake: 1000 mg/day

    • Sources: Dairy, fortified plant milks, almonds, tofu, leafy greens

    • Magnesium sources: Pumpkin seeds, whole grains, spinach

    • Note: If you’re not getting enough calcium from food, a supplement may be needed, especially if breastfeeding is planned.

    Omega-3s (especially DHA)

    • Why: Important for brain, retina, and nervous system development

    • Sources: Oily fish 1–2x/week (salmon, sardines), or a vegan algae DHA supplement

    Vitamin D

    • Why: Aids calcium absorption and supports immune health

    • Recommendation: 10 mcg (400 IU) daily - year-round in the UK

    • Tip: supplement during pregnancy as it’s hard to meet needs from food alone

    Protein

    • Why: Crucial for continued fetal growth and maternal changes

    • Goal: ~75–100g/day

    • Sources: Poultry, fish, dairy, tofu, beans, Greek yogurt

  • In the third trimester, continue your prenatal multivitamin and consider adjustments based on symptoms or lab results:

    Still Needed:

    • Folate (400–600 mcg)

    • Iron (10–27 mg, if indicated and tolerated)

    • Iodine if diet inadequate (150 mcg)

    • B12 (2.6 mcg)

    • Vitamin D (10-25 mcg)

    + May Also Need:

    • DHA (if not in your prenatal or not eating oily fish)

    • Magnesium (for sleep, cramps, constipation)

    • Extra calcium or iron if your dietary intake is low

    Reminder: Supplements are not a substitute for a balanced diet - but they can fill important gaps, especially in the third trimester when nutritional demands are high.

  • Between weeks 28 and 32, your midwife or doctor will typically arrange a blood test to check your haemoglobin (a marker of red blood cells) and ferritin (your body’s iron stores). This test is done routinely in pregnancy because your blood volume increases by up to 50% during the second and third trimesters, increasing your demand for iron significantly.

    If these tests show low iron levels or anaemia, it’s important to take action, as this can affect both your health and your baby’s.

    Why Iron Checks Matter:

    • Iron is essential for making haemoglobin, which helps carry oxygen in your blood - both to your baby and your own organs.

    • Low iron can cause fatigue, dizziness, breathlessness, and leave you feeling depleted as you approach labour.

    • Severe anaemia is associated with an increased risk of preterm birth, low birth weight, and postpartum blood loss.

    • Treating iron deficiency early can support energy, immune function, and recovery after birth.

    What to Do If Iron Is Low

    If your haemoglobin or ferritin are below recommended levels:

    Add more iron-rich foods:

    • Red meat, chicken, and fish

    • Lentils, chickpeas, and beans

    • Iron-fortified cereals

    • Pumpkin seeds, tofu, dried apricots

    • Always pair with a source of vitamin C (e.g. citrus, strawberries, peppers) to enhance absorption.

    Adjust or start supplementation:

    • You may be advised to take an iron supplement - often starting with 30–60mg elemental iron/day.

    • If standard forms (like ferrous sulfate) cause side effects like nausea or constipation, ask about gentler forms such as iron bisglycinate.

    Some common foods and drinks can block the absorption of iron, so best to limit these, or don’t consume alongside an iron-rich food:

    • Tea, coffee, calcium supplements, and high-fibre bran cereals can all reduce absorption - take iron at least 1–2 hours away from these.

    Follow up testing:

    • You may be retested after 2–4 weeks of dietary and/or supplement changes to check if your levels are improving.

Getting Ready for Labour & Breastfeeding

As your due date approaches, your nutritional choices in the third trimester play a critical role in preparing for labour, postpartum healing, and the early stages of breastfeeding.

During these final weeks, your baby continues to accumulate key nutrients - including iron, calcium, omega-3s, and fat stores - all of which are drawn from your diet or your body’s nutrient reserves. At the same time, your body is preparing for the intense physical demands of birth and the energy requirements of lactation.

  • Even though labour is unpredictable, certain nutritional strategies may support stamina, smoother delivery, and postpartum recovery:

    Iron & Protein

    • Why it matters: Iron is vital to build your blood volume and protect against fatigue, particularly as blood loss is expected during delivery. Protein supports tissue repair.

    • How to get it: Include iron-rich, protein-packed meals like red meat and lentils with vitamin C-rich foods (peppers, citrus). Tofu, eggs, beans, and Greek yogurt also support muscle and tissue health.

    Hydration

    • Why it matters: Staying hydrated helps maintain energy levels, regulate body temperature during labour, and prevent constipation post-birth.

    • How to get it: Aim for 6–8 glasses/day — water, coconut water, herbal teas (e.g. raspberry leaf in late pregnancy if advised), and broths all count.

    Dates from 36 Weeks

    • What the evidence says: Several small studies - including a 2011 randomized trial published in the Journal of Obstetrics and Gynaecology - have suggested that eating 3–6 Medjool dates per day from 36 weeks may:

      • Support cervical ripening

      • Increase the likelihood of spontaneous labour

      • Reduce the need for labour induction

      • Shorten the first stage of labour

    • How to include them: Blend into smoothies, stuff with nut butter, or eat as is. They’re rich in fibre, potassium, and natural sugars - ideal for energy.

    As always, consult your midwife, dietitian, or doctor before making any dietary changes in late pregnancy.

  • From week 35 onward, your body starts to build milk stores and signal prolactin production. The nutrients you take in now can influence early milk supply and your ability to meet your baby’s needs after birth.

    Focus on:

    • Iodine – essential for milk production and your baby’s brain development

      • Sources: seafood, dairy, iodised salt, fortified plant milks

      • Needs: ~150 mcg/day; check your prenatal contains this

    • Calcium – vital for maternal bone health and milk mineral content

      • Sources: dairy products, leafy greens, calcium-fortified alternatives

      • Aim: ~1000 mg/day

    • Vitamin B12 – crucial for energy, red blood cell production, and brain development (especially important for vegans)

      • Sources: meat, dairy, eggs, fortified plant-based milks/cereals

      • Needs: 2.6 mcg/day

    • Choline & Omega-3s (DHA) – support infant brain and eye development, and maternal cognition

      • Choline: eggs (esp. yolks), soy, peanuts

      • DHA: oily fish (salmon, sardines), algae-based supplements

  • As you near the end of pregnancy, it’s a good time to review your supplement routine - especially if you plan to breastfeed.

    A high-quality prenatal supplement is still suitable through the third trimester and into the early postpartum period, but your nutritional needs may shift once baby arrives.

    If you're planning to breastfeed:

    You may need to continue or adjust the following:

    • Vitamin D

      • Still essential postnatally for both maternal bone health and infant vitamin D status, especially if exclusively breastfeeding.

      • UK guidance recommends 10 mcg (400 IU) daily for mothers, and 400 IU/day for breastfed babies from birth.

    • Iodine

      • Needs increase during breastfeeding to support milk iodine content and infant brain development.

      • Recommended amount rises to 200 mcg/day in lactation - not always included in UK prenatals, so check your label.

    • Iron

      • If your iron stores were low or if you had significant blood loss during birth, you may need to continue with supplementation to restore levels and reduce fatigue.

      • Only continue high-dose iron if advised by your provider.

    • Omega-3s (DHA)

      • DHA supports your baby’s cognitive and visual development while breastfeeding.

      • Aim for 200–300 mg/day via oily fish or algae-based supplements if not included in your multivitamin.

    • Vitamin B12

      • Still important postnatally - especially for those following vegetarian or vegan diets.

    What to do now:

    • Review your current prenatal to see if it still meets your needs.

    • You may not need to switch supplements entirely - sometimes, adding individual nutrients (like iodine or DHA) is enough.
