What to Eat and Drink While Breastfeeding

Contrary to popular belief, there are no foods you should eat or avoid while breastfeeding. Interestingly, you don’t have to drink milk to make milk. Your body has the amazing ability to make milk out of anything you eat. But we do get lots of questions about what to eat and drink while breastfeeding? So here are some of our collective thoughts.


Let's bust some breastfeeding myths straight away:

Most mothers can eat chocolate, spicy foods, onions, broccoli, cabbage. The key is everything in moderation.

Eat to hunger, there is no need to consciously eat extra calories!

Drink to Thirst, not to prescribed amounts.

Research has not yet found a connection between a mothers intake and her milk production. 


Growlife Medical looks at the issue of what to eat and drink while breastfeeding, breastfeeding supplements, tea, caffeine and alcohol.

What to eat and drink while breastfeeding | Grow Medical

Breastfeeding Diet

What do you do if your baby seems to react to something you have eaten as a result of your breastfeeding diet?


Remember first of all, that almost all babies have fussy periods. Your baby's fussiness is probably unrelated to your diet, especially if you do not see other physical signs of allergy or sensitivity such as rash, congestion or digestive upset.


If you do suspect a food is affecting your baby, it is best to see one of our GPs for an initial examination to check for common problems like problems with latch, hunger, growth & development and causes of pain such as an ear infection or sore throat. If it appears likely, your doctor may suggest eliminating the suspect food from your diet. It may take a couple of weeks for you to notice a difference. Cow’s milk and dairy are the most common foods to cause allergy and associated gastrointestinal upset. If dairy is the cause, two weeks of complete elimination should be enough to resolve the problem. It is important to reintroduce the suspected food, as a recurrence of the symptoms will confirm the diagnosis. Never restrict your diet longer than two weeks without seeing a paediatric dietitian .


Most common foods that cause allergies are dairy, soy, egg, peanuts and wheat.


Before trying an elimination diet, it is advisable to seek professional help from an IBCLC first to ensure that attachment is good and milk transfer is efficient. Poor fit and hold with breastfeeding, and switching breasts too soon, could lead to too much lactose which can cause digestive issues and an unsettled baby.


Breastfeeding Supplements

Most mothers can get enough vitamins and minerals by eating a balanced and nutritious diet full of fresh fruit and vegetables without the need for breastfeeding supplements. It is often recommended, however, that breastfeeding women take a vitamin D supplement, particularly during the winter months when sunlight is less easy to access. For more information about supplements we suggest speaking with your doctor or lactation consultant.

Breastfeeding Tea

Some herbal teas (typically containing fenugreek) are postulated to stimulate breast milk production. As a general rule we feel that herbal teas are probably safe, and may have a small effect on increasing milk production based on a small amount of evidence. However, it is important to remember that most herbs contain complex chemical compounds, and in high doses could potentially be harmful to the liver or kidneys. Many herbal teas are great for helping you to relax and unwind, so like anything it is all about moderation. 

The most commonly used teas for breastfeeding include fennel, nettle, milk thistle, marshmallow root, coriander, blessed thistle, fenugreek, alfalfa, and caraway. Many commercial teas contain one or more of these ingredients and can be purchased at a relatively low cost.

Caffeine Breastfeeding

There is no need to abstain from caffeine while breastfeeding . One or two cups of coffee or other caffeinated drinks per day is unlikely to be a problem for most breastfeeding mothers and babies. We are on board with this one, as we have a lot of coffee lovers at Grow Medical!

Breastfeeding Alcohol

We are likely to see increased recommendations against consuming alcohol whilst breastfeeding in coming years. Historically it has been believed that drinking alcohol in moderation whilst breastfeeding does little harm, but it may be that we have not fully appreciated the impact of even low levels of alcohol consumption.

Moderate to heavy drinking whilst breastfeeding poses a risk to your baby's brain development. Occasional alcohol is likely to be less problematic, but may result in more disrupted sleep in your baby. Alcohol consumption may also cause a reduction in breastmilk supply. The alcohol from one glass of beer or wine is out of the milk within two to three hours.

You do not need to express your milk for the alcohol to pass out of it. Alcohol leaves your milk automatically as blood levels decrease. Pumping does not speed the removal of alcohol from your breastmilk.

Breastfeeding Support

The Australian Breastfeeding Association (ABA) runs the National Breastfeeding Helpline 1800 mum 2 mum (1800 686 268) for breastfeeding support. The Breastfeeding Helpline is available 24 hours a day, 7 days a week. It is staffed by trained, volunteer counsellors who answer calls on a roster system in their own homes.
