Breastfeeding is one of the most nourishing things you can do for your baby — but it also raises many questions about what you should and should not eat. What you consume can pass into your breast milk and potentially affect your baby. In this guide, Motherly covers the key foods to avoid while breastfeeding, with a special focus on the Indian diet.

Does Diet Really Affect Breast Milk?

Yes, but perhaps not as dramatically as many people assume. Breast milk is produced from your blood, so substances in your bloodstream — including nutrients, flavours, caffeine, alcohol, and certain chemicals — can find their way into your milk.

Motherly Tip: The good news is that most healthy Indian foods are perfectly safe while breastfeeding. A few categories of food and drink warrant caution — but restriction should never come at the cost of your overall nutrition.

Foods to Avoid While Breastfeeding

Here is a comprehensive list of foods and drinks that breastfeeding mothers should limit or avoid entirely:

Alcohol

Alcohol passes directly into breast milk at concentrations similar to your blood alcohol level. If you do drink, wait at least 2–3 hours per unit before breastfeeding, or pump and discard milk beforehand. There is no known safe level of alcohol for breastfed babies.

High-Mercury Fish

Shark, swordfish, king mackerel, and tilefish contain high mercury levels that can affect infant brain development. Choose low-mercury fish like rohu, catla, or prawns instead. Fish itself is nutritious — the concern is specific to high-mercury varieties only.

Excess Caffeine

More than 200–300 mg of caffeine per day (about 2 cups of tea or coffee) can make some babies irritable and disrupt their sleep. Factor in all sources — chai, coffee, green tea, and even some soft drinks — when calculating your daily total.

Highly Processed and Junk Foods

These provide empty calories and may displace nutritious foods from your diet. A breastfeeding mother needs an additional 300–500 calories per day from quality sources — not from chips, biscuits, or fried snacks.

Unpasteurised Dairy

Raw milk and cheeses carry a risk of Listeria infection, which can be particularly harmful during the postpartum period. Always choose pasteurised dairy products — commercially sold milk, paneer, and curd are generally safe.

Herbal Supplements

Many herbal supplements have not been tested for safety during breastfeeding. Always consult a doctor before taking any supplement — even those marketed as ‘natural’ or ‘Ayurvedic’. Culinary use of herbs and spices is a separate matter and generally safe.

Indian Foods That May Reduce Breast Milk Supply

Some ingredients commonly used in Indian cooking have been traditionally associated with reduced milk production. Scientific evidence is limited, but these are worth being aware of — particularly in large or medicinal quantities.

Parsley in large quantities — in very large amounts, parsley may have anti-galactagogue properties. Normal use as a garnish or in cooking is fine.

Peppermint (pudina) in high doses — high doses of peppermint or menthol may reduce milk supply in some women. Strong peppermint teas consumed daily are the main concern, not culinary use.

Sage in large medicinal quantities — similar to peppermint, sage in large doses is said to reduce supply. It is sometimes deliberately used by mothers who are weaning.

These effects are typically associated with very large or medicinal doses. Using these as everyday cooking spices in normal quantities is generally considered safe for breastfeeding mothers.

Foods That May Cause Baby Discomfort

Some babies are more sensitive to what their mother eats. If your baby seems unusually gassy, colicky, or fussy after feeds, consider temporarily reducing these foods one at a time:

Food	Potential Effect on Baby	What to Do
Cruciferous Vegetables	Increased gas and bloating	Reduce cabbage, cauliflower, broccoli temporarily
Dairy Products	Cow’s milk protein sensitivity	Try eliminating for 2 weeks and observe
Spicy Foods	Occasional fussiness	Reduce if a consistent pattern is noticed
Citrus Fruits	Nappy rash or digestive discomfort	Limit oranges and lemons if baby reacts
Soy Products	Sensitivity similar to dairy	Eliminate alongside dairy if testing
Wheat / Gluten	Bloating in sensitive babies	Eliminate one food at a time to identify trigger

Motherly Tip: Keep a simple food diary and note if your baby’s behaviour changes after you eat certain foods. Eliminate one food at a time for 1–2 weeks to identify triggers. Never eliminate multiple food groups at once without guidance from a lactation consultant.

Safe and Healthy Alternatives for Breastfeeding Mothers in India

Instead of focusing only on what to avoid, focus on building a diet full of nourishing foods that support both you and your baby:

Ragi, oats, and whole grains — for sustained energy and iron, ideal at breakfast or as a mid-morning snack

Dal, paneer, eggs, and lean meats — excellent protein sources that support milk production and postpartum recovery

Methi seeds, garlic, and jeera — traditional Indian galactagogues that may actively support milk supply

Plenty of fluids — water, nimbu paani, coconut water, and buttermilk all count; aim for at least 3 litres daily

Seasonal fruits and vegetables — rich in vitamins, antioxidants, and fibre to support overall maternal health

Nuts and seeds — soaked almonds, walnuts, and til (sesame) are calorie-dense and packed with calcium, omega-3, and healthy fats

Frequently Asked Questions

Can I eat spicy food while breastfeeding? +

In most cases, yes. Most babies are entirely unaffected by spicy food in their mother’s diet. However, if your baby becomes unusually fussy or gassy after you eat something spicy, try reducing it temporarily and observing whether the pattern changes.

Does eating garlic affect breast milk taste? +

Yes — garlic can subtly change the flavour of breast milk. Interestingly, some studies suggest babies may actually feed longer when their mother has eaten garlic, perhaps because they enjoy the taste. Garlic in cooking is not only safe but potentially beneficial.

Is it safe to drink chai while breastfeeding? +

Yes, in moderation. One or two cups of chai per day is generally safe and well within recommended caffeine limits. Excessive caffeine — more than 300 mg per day — can make some babies irritable or disrupt their sleep. Factor in all other caffeine sources when calculating your daily total.

Can I eat non-veg food while breastfeeding? +

Absolutely. Non-vegetarian food is an excellent source of protein, iron, and B12 — all important for breastfeeding mothers. Just avoid high-mercury fish (shark, swordfish, king mackerel) and make sure all meat and eggs are thoroughly cooked.

What should I avoid eating if my baby is colicky? +

Common dietary triggers for colic include dairy, cruciferous vegetables, soy, and wheat. Try eliminating one food at a time for 1–2 weeks to see if your baby’s symptoms improve. Never eliminate multiple food groups at once without expert guidance. Motherly’s lactation experts can help guide this process systematically.
