Although both chestnut and milk contain a lot of nutrients, there is a mutual reaction between some ingredients, which will produce some substances that are difficult to be absorbed by the stomach, which is not good for health.
Harm of eating chestnut and milk together
Chestnut contains starch, and protein is more. If you eat too much, it will not be easy to digest. Milk contains too much calcium. If you eat both together, protein and calcium will precipitate, resulting in indigestible substances, which are difficult to be absorbed by the stomach and intestines, easily causing indigestion and flatulence.
