Oranges and Milk
For about one hour before or after drinking milk, it is not advisable to eat oranges. This is because when the protein in milk comes into contact with the citric acid in oranges, it will coagulate, thereby affecting the digestion and absorption of milk. During this period, it is also not suitable to consume other acidic fruits.
Juice and Milk
80% of the protein in milk is casein. When the pH of milk is below 4.6, a large amount of casein will coagulate and precipitate, making it difficult to digest and absorb. In severe cases, it may even lead to indigestion or diarrhea. Therefore, acidic beverages like juice should not be added to milk.
Milk and Sugar
The lysine in milk can react with fructose under heating conditions to form toxic fructoselysine, which is harmful to the human body. Therefore, do not add sugar when boiling fresh milk. It is not too late to add sugar after the milk has been boiled and cooled slightly.
Milk and Chocolate
Milk is rich in protein and calcium, while chocolate contains oxalic acid. Consuming them together can form insoluble calcium oxalate, which significantly affects the absorption of calcium. This can even lead to symptoms such as dry hair, diarrhea, and slow growth.
Milk and Medicine
Some people like to take medicine with milk instead of plain water. In fact, milk can significantly affect the body's absorption of medication.
Because milk can easily form a coating on the surface of the drug, the calcium and magnesium minerals in the milk can react with the drug to form insoluble substances, thereby affecting the release and absorption of the drug's efficacy. Therefore, do not drink milk for one hour before or after taking medication.
