You can't add pure milk when freshly squeezed juice. Protein in milk is 80% casein. When the pH value of milk is lower than 4.6, a large amount of casein will agglutinate and precipitate, which is difficult to digest and absorb, and even lead to indigestion or diarrhea. Therefore, it is not advisable to add acidic drinks such as fruit juice to milk.

Extended data:

Several groups of foods that are not suitable for milk:

1, oranges and milk:

Oranges should not be eaten before and after drinking milk 1 hour. Because once protein in milk meets the fruit acid in orange, it will solidify, which will affect the digestion and absorption of milk, and it is not suitable for eating other acidic fruits during this period.

2. Milk and sugar:

Lysine contained in milk can react with fructose under heating conditions to produce toxic fructosyl lysine, which is harmful to human body. Don't add sugar when boiling fresh milk. It's not too late to add sugar when the milk is cooked and cold.

3. Milk and medicine:

Some people like to take medicine with milk instead of boiling water. In fact, milk obviously affects the human body's absorption of drugs. Milk is easy to form a covering film on the surface of drugs, which makes calcium, magnesium and other minerals in milk react with drugs to form water-insoluble substances, thus affecting the release and absorption of drug effects. Do not drink milk before and after taking the medicine 1 hour.
