​Acidic foods

Foods containing a lot of protein contain more elements such as sulfur and phosphorus. After conversion by the human body, most of the final products are acidic, so they are called acidic foods. Although whole grains do not contain high amounts of protein, they are also acidic because they contain excess phosphorus. Most fruits are alkaline foods because they are rich in potassium, magnesium, calcium, etc., but plums, plums, etc. are acidic in the human body because they contain organic acids that the human body cannot metabolize and enter the urine directly. It should be pointed out that although milk and some dairy products are rich in protein, they also have an alkaline reaction because they also contain sufficient calcium.

​Alkaline foods

Most vegetables and fruits are rich in inorganic salts such as calcium, potassium, sodium, magnesium, etc. Their final products in the human body are alkaline, so they are called alkaline foods. People may wonder why fruits with prominent sourness such as citrus and grapes are classified as alkaline foods. This is because the "sour" taste is not the criterion for judging the acidity or alkalinity of food. The acidity of their metabolites Alkalinity is the basis for judgment. The metabolites of organic acids (ascorbic acid, oxalic acid and other acids) contained in these "sour" foods are alkaline, so they are still alkaline foods. Certain dried fruits such as coconuts, apricots, and chestnuts are alkaline foods, while peanuts, walnuts, etc. are acidic foods.

After exercising, you should mainly consider alkaline foods

After exercise, sugar, fat, and protein in the human body are decomposed in large quantities, producing acidic substances such as lactic acid and phosphoric acid. Eat less acidic food, as it will make body fluids more acidic, which is not conducive to relieving muscle soreness and physical fatigue. Therefore, alkaline foods should be the main food.

Some people may ask, how long after exercise do you need to pay attention to these things? It is recommended that the first meal after exercise should be based on alkaline foods.
