Yogurt is an alkaline food. Although it tastes sour, it contains a lot of calcium and active substances, so it is an alkaline food. Drinking a cup of yogurt every day has a good health care effect. The acidity and alkalinity of food refers to the superiority of anions or cations produced by digestion, absorption and metabolic decomposition of food.

According to the food composition table, every100g of milk contains135mg of calcium,157mg of potassium, 1 1 mg of magnesium, etc. According to the pH value of food, milk belongs to "strong alkali food". Therefore, it is a common sense mistake to say that milk is an "acidic food". It is also wrong not to drink yogurt after exercise.

Eating alkaline food makes the body alkaline or weakly alkaline, which is conducive to maintaining health. It can be seen that the acidity and alkalinity of food is determined by the advantages of anions or cations produced by digestion, absorption and metabolic decomposition of food.
