Milk is best not eaten with grapes.

Grapes are rich in acid, and when combined with proteins in milk, they can form flocculent material that is difficult to absorb,

which affects human digestion and even symptoms such as abdominal pain, diarrhea, and vomiting.

Grape ellagic acid content is too high, will reduce the digestion and absorption of protein in milk.

Tannins are polyphenolic polymers under the action of digestive enzymes, it combines with proteins to form insoluble complexes, thus affecting the absorption and digestion of food

Thanks, thanks.
