First Month of Pregnancy Diet Chart: Foods to Eat and Avoid, Week by Week

Reviewed by Dr. Neeru Thakral, Director and Senior Obstetrician and Gynaecologist, Thakral Hospital and Fertility Centre, Gurgaon.

In the first month of pregnancy, eat regular small meals built around folate-rich vegetables, dal and pulses, whole grains, milk or curd, and fully cooked eggs, chicken or fish. Take your folic acid tablet daily. Avoid alcohol, raw or undercooked meat and eggs, unpasteurised milk and soft cheese, high-mercury fish, raw sprouts, unripe papaya, street food and more than one to two cups of tea or coffee a day.

Most women do not know they are pregnant for the first two to four weeks. That is why the first month feels confusing. You may have only just seen the faint line on the test, yet well-meaning relatives are already telling you what to eat and what to stop. This guide gives you one clear plan, week by week, with ordinary Indian food. It is based on what we advise patients at our maternity hospital in Gurgaon.

How doctors count the first month

Pregnancy weeks are counted from the first day of your last period, not from the day of conception. So by the time your period is late, you are already about four weeks pregnant. Weeks one and two happen before the egg is even released. Conception usually happens around week three, the embryo settles into the womb during week four, and by weeks five and six the baby's heart begins to form and beat. This is why good eating before and just after the missed period matters, even when you are not sure yet.

Week-by-week diet chart for the first month

Week	What is happening	Focus on	Easy Indian options
Weeks 1 and 2	Your period and the days before ovulation. You may not know you are pregnant.	Folic acid, iron, protein, water. Stop alcohol and smoking if you are trying to conceive.	Dal, spinach or methi sabzi, curd, fruit, roti with ghee in moderation, plenty of water.
Week 3	Ovulation and fertilisation.	Keep folic acid daily. Eat protein at every meal.	Paneer, eggs, sprouted moong (cooked), chana, nuts, seeds.
Week 4	The embryo implants. Your period is due or late.	Folate, vitamin B12, vitamin C, fluids. Confirm the pregnancy.	Poha with peanuts, fruit, lemon water, curd rice, vegetable dalia.
Weeks 5 and 6	The neural tube and heart form. Nausea starts for many women.	Small, frequent bland meals, ginger or lemon for nausea, protein, hydration.	Dry toast or khakhra, banana, boiled potato, idli, khichdi, buttermilk, coconut water.

If your cycles are irregular, ask your doctor for an early scan so that your weeks are counted correctly.

Foods to eat in the first month

1. Folate-rich foods

Folate helps the baby's brain and spinal cord close properly in the early weeks. Natural sources include spinach, methi, broccoli, peas, rajma, chana, lentils, oranges and sprouts that have been cooked. Food alone is not enough, so a folic acid tablet is advised for every woman trying to conceive or in early pregnancy, usually 400 micrograms a day. Women with diabetes, epilepsy, obesity or a previous baby with a neural tube defect may be given a much higher dose, but only on a doctor's prescription. Never increase the dose on your own.

2. Protein

Protein builds the placenta and the baby's tissues. Vegetarian choices are dal, rajma, chana, paneer, curd, milk, soya, tofu, nuts and seeds. Non-vegetarian choices are eggs, chicken and fish, always fully cooked.

3. Whole grains and complex carbohydrates

Roti made from whole wheat, millets such as ragi and jowar, brown rice, oats and dalia give steady energy and fibre. They keep your blood sugar level stable and ease constipation.

4. Dairy or calcium-rich foods

Have two to three servings a day: milk, curd, buttermilk or paneer. Use only pasteurised milk. If you do not take dairy, ask your doctor about calcium from ragi, sesame, almonds and fortified foods.

5. Iron-rich foods with vitamin C

Spinach, beetroot, dates, jaggery in small amounts, pomegranate, and pulses supply iron. Add lemon, amla, tomato or orange to the same meal, as vitamin C helps your body absorb iron. Drinking tea or coffee with the meal does the opposite, so keep them an hour apart.

6. Healthy fats

Nuts, seeds (flax, chia, sesame), mustard or groundnut oil in sensible amounts, and low-mercury fish if you eat fish provide omega-3 fats for the baby's brain.

7. Water and fluids

Aim for 8 to 10 glasses a day, more if you vomit. Water, coconut water, buttermilk, thin dal soup and nimbu pani all count.

Foods to avoid in the first month of pregnancy

Avoid	Why
Alcohol	No amount has been proven safe in pregnancy. Stop completely.
Raw or undercooked meat, chicken, fish and eggs (runny yolk, homemade mayonnaise, raw egg shakes)	Risk of salmonella and other infections. Cook until no pink remains and yolks are firm.
Unpasteurised milk and soft cheeses made from it	Risk of listeria, which can harm the baby. Boil milk or buy pasteurised milk.
High-mercury fish: shark, swordfish, king mackerel, tilefish	Mercury can affect the baby's nervous system. Choose low-mercury fish, well cooked.
Raw sprouts, street salads, pani puri and chaat from stalls	Contamination from water and handling.
Raw or unripe papaya	Contains latex that may stimulate the uterus. Ripe papaya in small amounts is generally considered safe.
Liver and very high vitamin A supplements	Too much preformed vitamin A can harm the baby. Take only the prescribed prenatal vitamin.
More than 200 mg caffeine a day	That is about one to two cups of tea or coffee. Higher intake is linked to a greater risk of problems.
Herbal teas, "detox" drinks and unproven remedies	Many plants haven't been tested during pregnancy.
Packaged and deep-fried junk food	Not harmful in a small amount, but it crowds out nutrients and can worsen nausea.

Can I eat chicken, eggs and fish in early pregnancy?

Yes, if they are cooked properly. Cook chicken until the juices run clear and the meat is no longer pink (the centre should reach about 74 degrees Celsius). Eggs should have a firm white and yolk. Fish should be fresh and cooked through. Reheat leftovers until steaming hot and eat them within a day. Chicken in a home-cooked curry is a good protein choice, and there is no need to avoid it because of old beliefs that it causes "heat".

What about pineapple and papaya? Normal servings of ripe pineapple and ripe papaya are safe. The old belief that they cause miscarriage comes from the effect of large amounts of raw papaya latex, not from fruit on your plate.

Managing nausea and still eating well

• Eat something dry such as a biscuit or khakhra before you get out of bed.
• Have five or six small meals instead of three big ones.
• Sip ginger tea, lemon water or coconut water slowly through the day.
• Avoid strong smells, very oily food and long gaps without eating, which make nausea worse.
• If you cannot eat much, do not worry for a short time. Keep taking folic acid and sip fluids. Call your doctor if you cannot keep fluids down for a day.

Sample one-day menu (vegetarian and non-vegetarian)

Meal	Vegetarian	Non-vegetarian
On waking	Khakhra or 2 biscuits, then warm lemon water	Same
Breakfast	Vegetable poha with peanuts and a glass of milk	Two boiled eggs, toast and a fruit
Mid-morning	Seasonal fruit and a handful of soaked almonds	Same
Lunch	2 rotis, dal with spinach, a vegetable, curd and salad washed at home	2 rotis, chicken curry (well cooked), vegetable, curd
Evening	Buttermilk or coconut water with roasted chana	Same
Dinner	Moong dal khichdi with ghee, a vegetable and curd	Fish curry (low-mercury, well cooked) with rice and a vegetable
Bedtime	A glass of warm milk	Same

Supplements your doctor may suggest

A balanced diet covers most needs, but some nutrients are hard to get from food alone: folic acid, iron, calcium, vitamin D and, for vegetarians and vegans, vitamin B12. Do not buy multivitamins on your own. Many contain more vitamin A than is advisable in pregnancy. Your doctor will decide after your first blood tests. Dr. Neeru Thakral and her colleagues at the obstetrician and gynaecologist team in Gurgaon check your haemoglobin, thyroid, vitamin levels and blood sugar early, so the diet can be adjusted for you.

When to talk to a doctor about your diet

• You have vomiting several times a day, cannot keep food or fluids down, or are losing weight.
• You have diabetes, thyroid disease, anaemia or high blood pressure.
• You are vegetarian or vegan and do not take vitamin B12.
• You are underweight or overweight before pregnancy.
• You have had a food-related illness such as diarrhoea with fever.
