The role of alkaline food
1, the reasonable collocation of acid-base food can effectively maintain the acid-base balance of human body. Generally speaking, after the adjustment and cooperation of various organs of the human body, the pH value of body fluids will remain in a constant range. The foods we usually eat, such as meat, eggs, seafood, rice, potatoes, wine and sweets, are rich in protein, starch and sugar, and the products of these substances are acidic. Although the acid-base balance of the human body will not be out of balance because of eating a lot of meat or sweets occasionally, if you eat a lot of acidic food for a long time, it will easily increase the load on the kidneys, gradually weaken the ability of the kidneys to excrete acidic metabolites, and break the acid-base balance of the human body.
Because China people's eating habits are mainly starchy foods and meat, they should eat more alkaline foods, such as fresh fruits and vegetables, beans and kelp. So as to keep the acid-base balance.
2. Prevent acidosis in patients with cardiovascular diseases and diabetes. For people with cardiovascular diseases and diabetes, it is more important to eat more alkaline foods and pay attention to diet, because the risk of acidosis in these patients is higher than that in healthy people.
3, gout patients eat alkaline food also has certain benefits. Gout is a pathological change caused by urate crystal deposition, and it is a metabolic disease caused by abnormal purine metabolism and increased uric acid synthesis. Gout patients eat more alkaline foods such as vegetables, fruits, nuts and milk, which helps to promote the dissolution of urate accumulated in tissues. But gout patients with high purine food need to eat less. For example, peanuts are acidic foods with high purine content, so it is recommended that gout patients eat less.
4, after exercise, it is best to eat more alkaline food. Because after exercise, sugar, fat and protein are decomposed in large quantities, and acid substances such as lactic acid and phosphoric acid are produced during the decomposition process, which stimulates the human body and makes people feel tired. Reasonable intake of alkaline food can offset some acidic substances in the body and play a role in eliminating fatigue. In addition, eating alkaline food can also reduce the acidity of urine and reduce the risk of acid substances forming stones in the bladder.
