What I Ate During Pregnancy
for a Healthy Baby
No impossible clean-eating plans. Just honest, nourishing food that actually got me through all three trimesters.
Nobody warned me that the first trimester would make me want to eat nothing but plain crackers and ginger ale — and that surviving on that for a few weeks wouldn’t hurt my baby. Pregnancy nutrition is surprisingly forgiving, and far less restrictive than the internet makes it seem. Here’s what I actually ate, trimester by trimester, and what the science says matters most.
When just eating anything felt like a win
Let’s be honest about the first trimester: it’s brutal for many people. Nausea, food aversions, exhaustion, and a complete revolt against smells you used to love. I couldn’t look at chicken for six weeks. My beloved morning coffee smelled like metal.
And here’s the thing I needed to hear: this is normal, and your baby is resilient. In the first trimester, your baby is microscopic. Their nutrient needs are small. What matters most right now isn’t volume — it’s folate, staying hydrated, and eating whatever you can actually keep down.
🥬 The #1 nutrient in your first trimester: Folate
Folate (vitamin B9) is critical in weeks 3–8 when the neural tube is forming — before most people even know they’re pregnant. It dramatically reduces the risk of spina bifida and anencephaly. Get it from dark leafy greens, lentils, chickpeas, edamame, and fortified cereals. And take your folic acid supplement daily without fail.
My actual first trimester diet looked a lot like: plain toast, saltine crackers with peanut butter, bland pasta, cold fruit (somehow smell-free), smoothies when I could manage them, and ginger everything — ginger tea, ginger biscuits, ginger chews.
Foods that helped with nausea
💧 Hydration matters more than you think
Blood volume increases 40–50% during pregnancy. Dehydration worsens nausea, causes headaches, and contributes to fatigue. Aim for 8–10 glasses of fluid daily — water, herbal teas, broth, and juicy fruits all count. If vomiting is severe, electrolyte drinks can help replenish what’s lost.
Energy returns — and so does your appetite
The second trimester was, for me, a revelation after the fog of the first. Nausea lifted, energy returned, and suddenly food became exciting again. This is the trimester to really lean into nutrition — your baby’s bones, brain, and organs are developing rapidly, and your body is building them from what you eat.
You don’t need to “eat for two” — the actual additional calorie need in the second trimester is around 300–350 extra calories per day. That’s a handful of almonds and an apple, not a second plate. What matters much more than quantity is quality.
The nutrients doing the heavy lifting this trimester
🦴 Calcium & Vitamin D — for baby’s bones
Your baby builds their entire skeleton this trimester. If you don’t consume enough calcium, your body will draw it from your own bones. Aim for 1,000mg calcium daily from dairy, fortified plant milks, tofu, almonds, broccoli, and kale. Pair with Vitamin D (from sunlight, oily fish, eggs, or supplements) for proper absorption.
🩸 Iron — for blood and brain development
Iron needs nearly double during pregnancy. Low iron causes fatigue, increases infection risk, and is linked to low birth weight. Eat red meat, lentils, spinach, tofu, fortified cereals, and pumpkin seeds. Always pair plant-based iron with vitamin C (a squeeze of lemon, a glass of orange juice) — it dramatically improves absorption.
🐟 Omega-3 DHA — for brain and eye development
DHA is the building block of your baby’s brain and retinas. The best sources are oily fish (salmon, sardines, mackerel — low-mercury choices). If you don’t eat fish, an algae-based DHA supplement is just as effective and completely safe.
A sample day of eating in my second trimester
Greek yogurt with berries, a drizzle of honey, and a handful of granola · Glass of orange juice · Prenatal vitamin
Whole grain toast with peanut butter and banana slices · Ginger tea
Big spinach salad with chickpeas, roasted sweet potato, feta, pumpkin seeds, and lemon tahini dressing · Sparkling water
Apple with cheddar cheese · Small handful of almonds
Baked salmon with roasted broccoli and brown rice · Side of steamed edamame
Warm milk with a little honey · A square or two of dark chocolate (yes, really)
Eating well when everything feels squished
The third trimester brought a new challenge: a baby sitting directly on my stomach. Large meals became impossible. Heartburn arrived. My appetite was simultaneously enormous and completely cramped for space.
The solution is unglamorous but effective: eat small, frequent meals throughout the day rather than three large ones. Think 5–6 smaller portions. This keeps energy steady, helps manage heartburn, and gets nutrients in without the discomfort of overfilling a stomach with a baby pressed against it.
⚡ Magnesium — for sleep, cramps, and calm
Magnesium deficiency is common in late pregnancy and contributes to leg cramps, poor sleep, and muscle tension. Find it in dark chocolate, pumpkin seeds, almonds, spinach, black beans, and whole grains. Many women benefit from a supplement in the third trimester — ask your midwife or doctor.
🧠 Choline — the nutrient nobody talks about
Choline is critical for fetal brain development and is often under-consumed — most prenatal vitamins don’t contain enough. Eggs are the single best source (the yolk especially). Beef liver, salmon, soybeans, and chicken are also good sources. Aim for 450mg daily.
The foods I genuinely avoided — and why
This list is shorter than most people expect. Pregnancy dietary restrictions are based on real risks, but they’re often presented in ways that feel more restrictive than they actually are.
🚫 Avoid or limit during pregnancy
- High-mercury fish — shark, swordfish, king mackerel, tilefish. Low-mercury fish (salmon, sardines, trout) are actively encouraged — 2–3 portions a week
- Raw or undercooked meat, eggs, and shellfish — risk of salmonella, listeria, and toxoplasma
- Unpasteurised soft cheeses and dairy — brie, camembert, blue cheese, unpasteurised milk (listeria risk)
- Raw sprouts — alfalfa, bean sprouts, clover — can harbour bacteria even when freshly washed
- Alcohol — no safe amount has been established. The recommendation is none during pregnancy
- Excess caffeine — limit to under 200mg daily (roughly one small coffee or two cups of tea)
- Liver and pâté — very high in vitamin A in retinol form, which can be toxic in large amounts in pregnancy
Supplements I took throughout
Food first, always — but these filled genuine gaps, especially on the days when nausea ruled and my diet wasn’t perfect.
Eat well. Not perfectly.
