After strenuous physical exercise, especially after long-distance walking or long-distance running, people often feel soreness in their waist, legs or whole body muscles, exhausted, and perhaps hungry and thirsty. At this time, what kind of drink should be drunk and what kind of food should be eaten? Some people drink Coca-Cola bottles or chew chocolate candies. Don’t you know that drinking it when you are hungry, thirsty and tired The above-mentioned drinks and eating the above-mentioned foods are not only ineffective in relieving soreness and fatigue, on the contrary, they will also aggravate soreness and fatigue.
As we all know, food can be divided into two categories: alkaline food and acidic food. People must eat a combination of acid-base food to maintain the balance of the pH value of the blood in the body. The so-called acidic and alkaline foods are not identified by their taste or taste. The identification is mainly based on the chemical elements contained in the food after it is absorbed and oxidized by the body. Generally, foods containing more non-metallic elements such as nitrogen, sulfur, and phosphorus are acidic foods, while foods containing more metallic elements such as sodium, potassium, calcium, and magnesium are alkaline foods. Foods that do not taste sour are acidic foods. For example, vinegar is sour, and fruits such as oranges, plums, and apricots are also sour. However, they are not acidic foods. On the contrary, they are typical alkaline foods. Another example is grain, candy, cakes, fish, pork and other animal meats, etc., which are not alkaline foods and are all acidic foods.
Under normal circumstances, the pH of human blood is balanced, and it is better to be slightly alkaline. After intense physical labor and strenuous physical exercise, sugar, fat, and protein in the body will be decomposed in large quantities and produce more acid, making people feel soreness in waist, legs or whole body muscles, and making people feel tired and tired. If you drink a lot of Coca-Cola under such circumstances, Coca-Cola contains high sugar content and is an acidic food, and then eat chocolate candies, which are also acidic foods. After eating these things, they will definitely "add fuel to the fire" and will definitely increase the acidity in the blood, thereby aggravating the soreness of the human muscles and making it impossible to eliminate fatigue in time.
So, what should you eat after working or exercising? You should eat alkaline foods. Among animal foods, only milk and animal blood are alkaline foods, while the others are acidic foods. In terms of beverages, it is best to drink milk, soy milk, tea, juice (without sugar), mineral water or white water.Boiling water is also acceptable.
As for whether it is better to drink salt water or sugar water after exercise, it should be flexibly determined according to the specific situation.
Generally speaking, when you sweat a lot, especially when engaging in strenuous exercise in summer, you should drink some light salt water appropriately. In summer, when the temperature is high and the humidity is high, the human body dissipates a large amount of heat energy in time through perspiration to keep the body temperature relatively stable. When the body perspires a lot, it takes away a lot of inorganic salts, such as sodium, potassium, magnesium, etc. It has been measured that after running a marathon, 30 grams of sodium chloride is taken away with sweat. A person's daily intake of sodium chloride from food is only 10 to 15 grams. This will inevitably cause the body to lack salt, leading to fatigue and weakness, and even muscle spasms or cramps. Therefore, when engaging in strenuous exercise in summer, it is necessary to drink some light salt water.
When the intensity is not too high, the time is not too long, and the ambient temperature is not too high, exercise will generate less heat in the body and will not cause a large amount of sweating and loss of inorganic salts. At this time, there is no need to drink salt water or sugar water.
If you exercise for a long time, such as marathon running, long-distance cycling, etc., and your body consumes more energy, you should drink some sugar water or sugar salt water appropriately. As for general physical exercise, there is no need to drink sugar water.
As for food, the most suitable foods to eat after labor and exercise are tofu, dried tofu and various soy products, as well as fresh fruits, melons and various vegetables. These are great alkaline foods. Kelp is known as "the crown of alkaline foods". In addition, stir-fry sesame seeds and soybeans, add shredded ginger and a little salt, brew it with boiling water and eat it to quench thirst and satisfy hunger. Sesame seeds, soybeans, and ginger are all good alkaline foods. After eating them, they are also very beneficial to reducing the acidity in the blood and eliminating fatigue.
