What to eat (and avoid) during each trimester

Let’s break it down trimester by trimester, what to eat, what to skip, and how to make those pregnancy meals both nutritious and satisfying.

What’s on your plate mama? Seriously, what’s on your plate? Can I take a guess? Let’s see. Is it fried chicken? Fruit salad? Perhaps spicy noodles? Or maybe you’re craving that steaming plate of ugali and sukuma? Whatever it is, one thing is sure, pregnancy changes not just your body but your appetite too. Suddenly, foods you once loved make you queasy, and random cravings hit you at odd hours. But beyond the cravings and aversions, what you eat (and avoid) truly matters for you and your growing baby.

Let’s break it down trimester by trimester, what to eat, what to skip, and how to make those pregnancy meals both nutritious and satisfying.

First Trimester (Weeks 1–13): Fighting Nausea and Staying Nourished

The first trimester can feel like a roller coaster, morning sickness, fatigue, and cravings that make no sense. But even with all that, your baby’s organs and brain are developing rapidly, so you need key nutrients like folic acid, iron, and vitamin B6.

What to eat:

Ndengu (green grams), kunde, and spinach (sukuma wiki),  packed with folate and iron to help prevent birth defects.

Avocado, groundnuts, and boiled eggs; rich in good fats. 

Vitamin B6 to ease nausea.

Plain rice, arrowroots, sweet potatoes, or dry bread, gentle on your stomach when nausea hits.

Fresh fruits like pawpaw (ripe), oranges, and bananas to keep you hydrated and energized.

Plenty of water or light uji (porridge),  staying hydrated helps manage fatigue and nausea.

What to avoid:

Raw or undercooked eggs, meat, and fish,  they can carry harmful bacteria.

Soft cheeses or milk that’s not pasteurized.

Caffeine and alcohol, they interfere with your baby’s growth.

Strong-smelling or greasy foods if they worsen your nausea.

Tip: If food feels like your enemy, nibble small portions throughout the day and lean on your prenatal vitamins to fill in nutritional gaps.

Second Trimester (Weeks 14–27): The Energy and Growth Phase

Welcome to the “honeymoon phase” of pregnancy, nausea fades, your energy returns, and your appetite finally behaves! Now, your baby’s bones and muscles are forming fast. You’ll need more protein, calcium, and iron to keep up.

What to eat:

Lean meats, fish (like tilapia or omena), eggs, and beans, excellent sources of protein for tissue and muscle development.

Milk, mala, or fortified plant-based alternatives for calcium and strong bones.

Iron-rich foods like sukuma, liver (in moderation), and ndengu paired with vitamin C fruits like guava or oranges for better absorption.

Fruits and veggies for vitamins and fiber to prevent constipation, a common second-trimester struggle.

Whole grains like brown ugali, millet, or sorghum porridge for lasting energy.

What to avoid:

Excess salt; it can increase water retention and blood pressure.

Sugary snacks, mandazis, or sodas,  they may satisfy cravings but can lead to unnecessary weight gain.

High-mercury fish like kingfish or swordfish (stick to local options like tilapia).

Tip: Eat small, balanced meals and carry healthy snacks, think roasted groundnuts, boiled maize, or fruit slices, to maintain steady energy.

Third Trimester (Weeks 28–40): Preparing for the Finish Line

At this stage, your baby is putting on weight and getting ready for the world, while you’re likely feeling heavier, sleepier, and fuller faster. Your meals should now focus on maintaining strength, keeping your digestion easy, and preparing your body for labor.

What to eat:

Complex carbs like matoke, brown rice, sweet potatoes, and millet porridge, they give you sustained energy without making you sluggish.

Protein-rich foods such as beans, omena, and lean meat to build and repair tissues.

Iron-rich foods (sukuma, spinach, liver in moderation) to maintain good blood levels before birth.

Healthy fats from avocado, olive oil, and nuts, great for your baby’s brain development.

Hydrating foods like fruits, soups, and water, essential for amniotic fluid and preventing fatigue.

What to avoid:

Very spicy or greasy foods, they can trigger heartburn and indigestion.

Large heavy meals at night, these can cause reflux and disrupt your sleep.

Unverified herbal teas, always confirm with your doctor before taking any.

Tip: Smaller, more frequent meals are best now since your growing baby leaves little room for a full stomach.

Pregnancy isn’t about eating for two, it’s about eating right for two. Each stage has its needs, and your body will tell you what it craves and what it rejects. Listen to it, but also balance your cravings with smart nutrition choices. Whether you’re snacking on roasted maize by the roadside, enjoying a hot cup of uji in the morning, or digging into your plate of ugali and sukuma at dinner, remember, every bite is building a stronger, healthier baby.

So, what’s on your plate, mama? Make it count, for you and your little one.
