It is best not to eat ice cream while breastfeeding. Ice cream is a frozen semi-solid food, the main ingredients of which are milk or milk powder, cream and edible sugar, as well as coloring, flavoring and other additive ingredients. In terms of the ingredients of ice cream, as long as the quality of the additives is qualified, there is no significant adverse effect on the health of breastfeeding women and babies. Since ice cream is a cold food, if a breastfeeding woman eats too cold food, it will easily cause her own gastrointestinal tract dysfunction and diarrhea, which will affect breastfeeding. At the same time, eating too cold food may induce reproductive system infections and cause coldness in the uterus, especially in the 42 days after delivery, which may lead to poor uterine regeneration, bloody dew, dripping, and even induce postpartum infections. It is advisable not to eat ice cream or other foods that are too cold and stimulating during breastfeeding.
