The one rule that matters most
Pregnancy nutrition is simpler than the internet makes it look: eat a balanced plate, most days, in slightly growing amounts. You are not "eating for two" adults — by the third trimester you need only a modest amount more than usual.
A useful plate has four parts: half vegetables and fruit, a quarter whole grains (rice, roti, millets), a quarter protein (dal, eggs, milk, curd, fish or meat if you eat them), plus a little healthy fat.
Trimester by trimester
First trimester: nausea often rules. Do not force big meals — small, frequent, bland snacks are fine, and most babies grow perfectly through a queasy first trimester. Keep fluids up.
Second trimester: appetite usually returns. This is the time to build the habit of the balanced plate, with iron-rich foods (greens, dals, jaggery, meat) and calcium (milk, curd, ragi) daily.
Third trimester: the baby is growing fastest. Add a healthy extra snack a day, keep protein at every meal, and eat smaller, more frequent meals if heartburn sets in.
What to take, what to limit
- Take the supplements your doctor prescribes — folic acid early, iron and calcium as advised. They cover the gaps food cannot.
- Limit tea and coffee, and avoid alcohol and tobacco entirely.
- Avoid raw or undercooked meat and eggs, and unpasteurised milk.
- Wash fruit and vegetables well; prefer freshly cooked food over long-stored leftovers.
When to ask for help
If you cannot keep food or fluids down, are losing weight, or feel dizzy and weak, tell your doctor — do not wait for the next scheduled visit. And if you have diabetes, thyroid disease or high blood pressure, your diet plan should be made with your doctor, not from general articles like this one.
