It is best not to eat spicy food during lactation, but onions can be fried. Don't eat eggplant during lactation. Eggplant contains vitamin B6, which can restore milk. Don't eat cold food, so as not to cause baby's diarrhea, but fruit can be heated. Try to eat less or not to eat hot and dry food, such as garlic, leeks, fennel and so on. These foods are easy to get angry, which will cause the mother to get angry, thus affecting the baby.
But don't eat half-cooked food, and don't eat food or drinks containing preservatives.
I hope my answer is helpful to you.
