Milk and durian can be eaten together. There are some sayings on the Internet that you can't drink milk for 8 hours after eating durian, because durian contains organic acids and milk contains protein. Mixing the two will form casein, causing gastrointestinal discomfort. "

However, according to Professor Lin, director of the Department of Food Safety, College of Light Industry and Food Engineering, Guangxi University, the organic acids in durian are very weak after entering the stomach. The gastric juice in human stomach contains hydrochloric acid, and its PH value is 2, which is much stronger than that of organic acids. When milk enters the stomach, it will instantly react with gastric acid and solidify. Because of this, when the baby spits out milk, all he spits out is milk residue, and there is no liquid milk. Therefore, the argument that the synthesis of organic acids and protein after eating durian leads to gastrointestinal discomfort is untenable. If someone feels uncomfortable after eating durian and drinking milk, it is probably because of gastrointestinal problems and can't digest milk, which has nothing to do with durian.
