Foods That Support Milk Supply

Few worries land harder on a new mother than the fear that she is “not making enough.” In the Cantonese confinement tradition I cook within, milk supply is treated with deep care — there is a whole repertoire of nourishing soups meant to encourage it. Families in Taiwan call these foods 發奶; in Hong Kong the word is 上奶. Both point to the same loving wish: that the milk comes in, flows freely, and feeds the baby well.
I want to honour that tradition honestly. Some of what we are taught about milk-making foods is wisdom worth keeping, and some is folklore that, gently, the evidence does not support. Here is how I hold both.
How does milk supply actually work?
The single most important thing to understand is that breast milk works on demand and supply. The more often and more effectively milk is removed — by your baby feeding well, or by a pump — the more your body is signalled to make. Frequent, effective feeding in the early weeks is what builds and protects supply. No soup, herb or supplement substitutes for that.
Around this central engine, three supporting conditions matter, and this is where good food earns its place:
- Hydration. Making milk raises your fluid needs. You do not need to flood yourself, but you should drink to thirst and keep something warm within reach all day.
- Eating enough. A breastfeeding body needs real fuel. Under-eating, which is easy to do in the blur of newborn days, is no friend to supply.
- Rest, as much as it is possible. Exhaustion and high stress do not help. They will not switch your milk off, but a mother who is fed, watered and a little rested simply copes better.
This is the honest frame: nourishing food does not magically “make milk.” It keeps the mother well so that frequent feeding — the real driver — can do its work.
What are the traditional Cantonese milk-supply foods?
This is the part families ask about most, and it is genuinely lovely. Cantonese 月子 (confinement) cooking has a beautiful set of 補身湯水 (nourishing tonic soups) reached for when a mother wants to encourage her supply:
- Peanut and pig-trotter soup (花生豬腳湯). Rich, collagen-laden and deeply traditional, this is perhaps the most famous “milk soup” of all.
- Octopus and lotus-root soup (章魚蓮藕湯). A savoury, mineral-rich brew long believed to nourish blood and encourage milk.
- Green-papaya fish soup (木瓜魚湯). Unripe papaya simmered with fish — often carp or snakehead — is the classic galactagogue soup across southern China and much of Asia.
- Tong cao (通草). A traditional herb added to soups specifically with the intention of “promoting” milk flow.
- Various fish and green-papaya soups more broadly, prized for being protein-rich, warming and gentle on the stomach.
I cook these with real respect, because they carry generations of care, they are wholesome and protein-rich, and they comfort a tired mother. What I will not do is promise they are proven medicine. They are tradition and nourishment — not clinical proof. Treated that way, they have a wonderful place at the confinement table.
What does the evidence say about common galactagogues?
Beyond the soups, certain foods and supplements are widely promoted as milk-boosters. Here is where the research actually sits:
- Oats. Gentle, wholesome and widely eaten by nursing mothers. There is no strong proof they raise supply, but they are a nourishing, comforting whole grain with no downside — an easy yes.
- Brewer’s yeast. A traditional favourite, often added to lactation cookies. The evidence is weak, but as a food it is harmless for most people.
- Fenugreek. The most studied herbal galactagogue, and the most cautioned. Results are mixed, and it is not risk-free — it can affect blood sugar and may interact with certain medications and conditions. It is not for everyone.
A fair summary: the high-quality evidence for any single galactagogue is thin. Many can be enjoyed safely as food, but concentrated herbs and supplements deserve caution. Before taking anything in supplement or herbal form while breastfeeding, talk to your doctor, pharmacist or a lactation consultant — herbs can interact with health conditions and medications, and “natural” does not mean automatically safe.
Do warm fluids and soups help?
Here tradition and common sense agree nicely. Staying well hydrated genuinely matters for milk-making, and a steady stream of warm soups and teas is a pleasant, effective way to get there — while also feeding the mother. Many women also notice their let-down feels easier with a warm drink in hand at the start of a feed. That comfort is real and worth leaning into.
So in my kitchen, the 月子湯水 flow all day: a clear fish soup at lunch, a warm tonic in the afternoon, red-date tea between feeds. Not because the broth is a drug, but because a warm, well-fed, well-hydrated mother is in the best possible shape to feed often.
What if my supply is genuinely low?
Sometimes the worry is real, and food alone is not the answer. If you sense your supply is truly low, this is the order I encourage:
- Increase effective removal first. Feed or pump more frequently, check the latch, and make sure your baby is actually transferring milk, not just comfort-sucking.
- Look after the basics. Hydration, enough food, and whatever rest you can steal.
- Get expert eyes early. If your baby is not gaining weight, has few wet nappies, or you are simply worried, contact your care provider or a lactation consultant promptly. An IBCLC can assess what is really happening and give a concrete plan.
Low supply has many causes, and a good number are very treatable once identified. Reaching out early is wisdom, not weakness.
And please hear this clearly: combination feeding and formula are okay. A fed baby and a well mother matter more than any feeding ideal. If you need to top up, or to formula-feed in part or in full, you have not failed — you have made a loving choice for your family. I have cared for many mothers through exactly this, and there is no shame in it, only good mothering.
A warm word to end on
Whether your milk comes easily or with effort, you are already doing the tender, relentless work of feeding a new life. Let the soups be what they truly are — comfort, nourishment and a thread of care reaching back through generations — rather than a test you must pass. Eat well, drink warm, rest when you can, feed often, and ask for help early.
When the cooking feels like one task too many, that is exactly what we are here for. At Julia’s Kitchen we prepare fresh, nourishing confinement meals and traditional milk-supply soups — green-papaya fish soup, peanut pig-trotter soup, warming tonics and red-date tea — and deliver them across Greater Vancouver, so you can rest, feed your baby, and be cared for the Cantonese way.

Frequently asked questions
Do these traditional foods really increase my milk supply?
They can certainly help indirectly, but not the way folklore often promises. The biggest driver of supply is demand — how often and how effectively milk is removed by your baby or pump. What warming soups and nourishing meals genuinely do is keep you well fed, well hydrated and a little more rested, and those conditions support a mother who is already breastfeeding frequently. So enjoy the green-papaya fish soup and peanut pig-trotter soup as comfort and care, while letting frequent feeding do the real work.
Are green-papaya and fish soups scientifically proven to boost milk?
Not in the strict clinical sense. There is no strong, high-quality evidence that any single galactagogue food reliably raises supply on its own. These soups are valued in Cantonese and wider Asian tradition, and they are wholesome, protein-rich and hydrating, which is helpful. I serve them as honoured tradition and good nourishment, not as a proven medicine — and I am always honest with mothers about that difference.
What should I do if my supply is genuinely low?
First, increase effective milk removal — nurse or pump more often, check the latch, and make sure your baby is actually transferring milk. Stay hydrated, eat enough, and rest when you can. If your baby is not gaining weight well, or you are worried, contact your care provider or a lactation consultant promptly rather than relying on food alone. Low supply has many causes, and some are very treatable once identified.
Is fenugreek or brewer's yeast safe to take?
These are popular galactagogues, but the evidence is mixed and they are not risk-free. Fenugreek can affect blood sugar and may interact with some medications and conditions, and it is not suitable for everyone. Brewer's yeast and oats are gentler and widely eaten as food. Before taking any supplement or herb in concentrated form, especially while breastfeeding, check with your doctor, pharmacist or a lactation consultant.
When should I see a lactation consultant?
Sooner than most mothers think. Reach out if feeding hurts, if your baby is not gaining weight or has few wet nappies, if you suspect low or oversupply, or if you simply feel unsure. An International Board Certified Lactation Consultant (IBCLC) can assess latch and transfer and give a real plan. Asking for help early is wise, not a failure.
