After fitness exercise, I often feel muscle edema, joint pain and mental fatigue. In order to relieve fatigue as soon as possible, buy some chickens, fish, meat, eggs and the like for a big meal, thinking that this can supplement nutrition and meet physical needs. In fact, eating these foods at this time is not only not conducive to relieving fatigue, but also has adverse effects on the body.

Human food can be divided into acidic food and alkaline food. Judging the acidity and alkalinity of food is not based on people's taste, nor on the chemical properties of food dissolved in water, but on the acidity and alkalinity of the final metabolites produced after food enters the human body. Acidic food is usually rich in protein, fat and sugar, and contains more acid-forming elements. Acidic substances can be formed after metabolism in the body, which can reduce the PH value of blood and body. Vegetables, fruits, etc. It contains potassium, sodium, calcium, magnesium and other elements, which are metabolized into alkaline substances in the body and can prevent the blood from changing to acidity. Therefore, acidic fruit is an alkaline food rather than an acidic food. Chicken, fish, meat, eggs and sugar are all acidic foods, although they are not sour.

After a long-term study, a British pathologist pointed out that only eating more alkaline food can protect human health. Normal body fluids are weakly alkaline. People feel muscle and joint pain and mental fatigue after fitness exercise. The main reason is that a large number of sugar, fat and protein in the body are decomposed, and acid substances such as lactic acid and phosphoric acid are produced in the process of decomposition. These acidic substances stimulate human tissues and organs, making people feel muscle and joint pain and mental fatigue. At this time, if you simply eat meat, eggs, fish, etc. Rich in acidic substances, your body fluids will become more acidic, which is not conducive to fatigue relief. Eating vegetables, sweet potatoes, oranges, apples and other fruits, because of its alkalization, can eliminate excess general acids in the body, reduce the acidity of urine, increase the solubility of uric acid, and reduce the possibility of acid forming stones in the bladder.

Therefore, people should eat more alkaline foods, such as fruits, vegetables and bean products. After physical exercise, we can maintain the basic balance of pH in the body, maintain human health and eliminate fatigue caused by exercise as soon as possible.
