After exercise, sugar, fat and protein in the body will be decomposed in large quantities, producing more acid. So you will feel backache and particularly tired-at this time, it is necessary to supplement alkaline food and adjust the balance of blood environment in the body. Of course, the acidity and alkalinity of food has nothing to do with taste, but with chemical properties. For example, oranges, plums, apricots and other fruits are sour, but they are typical alkaline foods.

It is best to drink milk, soybean milk, tea, fruit juice (without sugar), mineral water or boiled water. After strenuous exercise in summer, you can drink some light salt water properly, but the salt should not be too high, otherwise it will affect digestion. Nothing to drink? Acidic foods with high sugar content, such as cola, will aggravate the degree of soreness.

Beans are a good choice, such as tofu, dried tofu and various bean products. Kelp is also a "leader" in alkaline food. You can also fry sesame soybeans, add ginger and a little salt, and brew with boiling water to quench your thirst. These are all good alkaline foods.
