Many people often feel muscle swelling, joint pain, and mental fatigue after intense fitness exercises (fitness products, fitness information) and sports (sports products, sports information). In order to quickly relieve fatigue, they buy chicken, fish, meat, eggs, etc., and have a big meal, thinking that this can replenish nutrition and meet the body's needs. In fact, eating these foods at this time not only fails to help relieve fatigue but also has adverse effects on the body.
Human food can be divided into acidic and alkaline foods. Acidic foods usually contain abundant proteins (protein supplement products, protein supplement information), fats, and carbohydrates, with more acid-forming elements, which form acidic substances after metabolism in the body, lowering the pH value of blood and the body; vegetables and fruits contain K, Na, Ca, Mg, etc., elements, generating alkaline substances after metabolism in the body, preventing blood from becoming acidic. Therefore, acidic fruits are alkaline foods rather than acidic foods, while chicken, fish, meat, eggs, sugar, etc., although not sour in taste, are actually acidic foods.
After long-term research, a British pathologist pointed out: Only when the body fluid is weakly alkaline can human health be maintained. After physical exercise, people feel muscle and joint soreness and mental fatigue, mainly due to the large-scale breakdown of sugar, fat, and protein in the body, producing lactic acid, phosphoric acid, and other acidic substances during the breakdown process. These acidic substances stimulate human tissues and organs, causing people to feel muscle and joint soreness and mental fatigue. At this time, if one solely consumes meat, eggs, fish, and other foods rich in acidic substances, it will make the body fluids even more acidic, which is not conducive to relieving fatigue. On the other hand, consuming vegetables, sweet potatoes, citrus fruits, apples, and other fruits can eliminate excess general acids in the body, reduce urine acidity, increase uric acid solubility, and decrease the possibility of acid forming stones in the bladder.
Therefore, after physical exercise, one should eat more alkaline foods such as fruits, vegetables, and bean products to maintain the basic balance of acidity and alkalinity in the body, keep the body healthy, and quickly alleviate fatigue caused by exercise.
