Breastmilk is high in lactose, but if the lactose content in breastmilk is too high, it will cause the baby to develop symptoms of gastrointestinal indigestion, such as nausea, vomiting, bloating, diarrhea, etc. or more undigested milk petals in the stool. During normal breastfeeding, diets should be low in sugar and grease, foods with high sugar content are not recommended, and foods with high sugar content should also be avoided. In addition, you should avoid eating excessively oily food, such as deep-fried or pan-fried, grilled and other greasy food, and ensure a light diet and a reasonable combination of food. Breastmilk produced through dietary changes has a normal lactose content and babies will not suffer from bloating, diarrhea and other lactose intolerance. If your baby often develops lactose intolerance due to consuming breastmilk with high lactose content, you can also add lactase enzyme before breastfeeding to speed up your baby’s digestion of breastmilk and avoid abnormalities in the digestive system such as lactose intolerance.
