At 8 weeks pregnant, your calorie needs haven’t increased much, but your nutrient needs have shifted significantly. The first trimester calls for roughly 1,800 calories per day for most normal-weight women, which is close to what you were eating before. What matters more right now is the quality of those calories: your baby’s fingers, ears, eyes, nose, and limbs are actively forming, and specific nutrients fuel that construction.
The challenge, of course, is that 8 weeks is often peak nausea territory. So the real question isn’t just what to eat, but how to get key nutrients into your body when food sounds terrible.
Nutrients That Matter Most Right Now
Three nutrients deserve special attention at this stage: folate, iron, and iodine. Your folate needs jump to 600 micrograms per day during pregnancy (up from 400 for non-pregnant women), and the World Health Organization recommends a 400-microgram folic acid supplement during the first eight weeks after conception specifically to reduce the risk of neural tube defects. Good food sources include leafy greens, broccoli, legumes, oranges, avocado, and fortified breads and cereals.
Iron requirements nearly double to 27 milligrams per day because your blood volume is expanding and your body is building the placenta. Red meat, poultry, tofu, and iron-fortified cereals are reliable sources. Pairing iron-rich foods with vitamin C (oranges, kiwi, bell peppers, broccoli) helps your body absorb more of it.
Iodine needs rise to 220 to 250 micrograms per day. Your best sources are low-fat dairy, eggs, and cooked fish or seafood. If you don’t eat these regularly, check whether your prenatal vitamin includes iodine, as not all of them do.
Protein: How Much You Actually Need
The first trimester protein requirement is about 46 grams per day, barely above the 44 grams recommended for non-pregnant women. The extra need at this point is roughly 1 additional gram per day. That number climbs to 71 grams per day in the second and third trimesters, so for now, you don’t need to overhaul your protein intake.
What’s worth knowing is that protein-heavy meals appear to reduce nausea more effectively than meals dominated by carbohydrates or fat. Distributing protein across five smaller meals throughout the day improves digestion and may lower nausea intensity. Good options include eggs, yogurt, legumes, poultry, fish, nuts, and cottage cheese.
Omega-3s for Brain Development
Your baby’s central nervous system is already developing, and it depends heavily on a specific omega-3 fatty acid called DHA. The dietary goal during pregnancy is about 300 milligrams of DHA per day. Two servings of low-mercury fish per week typically provides only 50 to 100 milligrams of DHA daily, so many women need to eat fish more frequently or supplement.
The best low-mercury options, with their DHA content per 6-ounce serving: sardines (1,200 mg), pollock (360 mg), scallops (360 mg), shrimp (320 mg), salmon (260 mg), and catfish (180 mg). If you don’t eat seafood, plant sources like flaxseed and canola oil contain a precursor form that your body converts to DHA very poorly. Algae-based DHA supplements are the most reliable non-fish option.
Calcium for Bone and Teeth Formation
Pregnant women need about 1,300 milligrams of calcium per day. Dairy is the most concentrated source: a cup of milk or yogurt provides roughly 300 milligrams. But if dairy doesn’t appeal to you right now (or ever), there are plenty of alternatives.
Half a cup of calcium-set tofu delivers 435 milligrams. Half a cup of calcium-fortified orange juice provides 250 milligrams. Canned sardines with bones (4 sardines) give you 185 milligrams, and canned salmon with bones offers 180 milligrams per 3-ounce serving. Navy beans, collard greens, turnip greens, and almonds all contribute meaningful amounts. Fortified plant milks (soy, almond, oat) can match cow’s milk if they’re specifically fortified, so check the label.
Eating When Everything Sounds Awful
Nausea at 8 weeks is extremely common, and it can turn even your favorite foods into enemies. Research consistently shows that eating patterns matter as much as food choices during this phase. Five or six small meals per day, rather than three large ones, keeps blood sugar stable and reduces nausea severity. Aim for 45 to 60 percent of your calories from complex carbohydrates like whole grains, legumes, and starchy vegetables, which help stabilize blood glucose.
Cold or room-temperature foods tend to be better tolerated than hot dishes because they produce fewer aromas. Think salads, smoothies, boiled eggs straight from the fridge, cottage cheese, or cold yogurt. At least five servings of fruits and vegetables per day is associated with reduced nausea, and 2 to 3 servings of cereal or grains daily has been linked to lower nausea incidence as well.
Every snack should include some protein. A handful of nuts, a spoonful of nut butter, or a few bites of cheese alongside crackers does more for nausea relief than crackers alone. Avoid fatty, fried, and spicy foods. Keep caffeine under 200 milligrams per day, which is roughly one to two cups of coffee. If you develop a strong aversion to meat, nuts, legumes, eggs, and tofu can fill the protein gap.
Foods to Avoid
Pregnant women are about 10 times more susceptible to listeria infection, which can cause miscarriage and stillbirth. The FDA specifically warns against these foods during pregnancy:
- Deli meats, hot dogs, and luncheon meats unless reheated until steaming hot
- Soft cheeses like queso fresco, queso blanco, and requesón, whether made from pasteurized or unpasteurized milk
- Unpasteurized milk and any foods made with it
- Refrigerated smoked seafood (labeled as lox, nova-style, kippered, or smoked) unless cooked into a dish like a casserole
- Refrigerated pâtés or meat spreads
- Raw or undercooked meat, poultry, and eggs
For fish, stick to low-mercury varieties. Shrimp, salmon, pollock, catfish, sardines, scallops, and light tuna are all low in mercury. Avoid high-mercury fish like shark, swordfish, king mackerel, and tilefish entirely during pregnancy.
Staying Hydrated
Your blood volume is increasing, and your body is beginning to produce amniotic fluid. Both require extra water. The standard recommendation is 8 to 10 glasses of water per day during pregnancy. If nausea makes plain water hard to tolerate, cold or frozen drinks are often easier to get down. Popsicles, ice chips, or chilled fruit-infused water can help you stay on top of hydration when sipping warm beverages feels impossible.
