Sodium, also known as "salt", is a very important condiment in people's daily life. As the saying goes, salt is the first of all flavors, so it often needs to be added to dishes, but too much sodium intake is more harmful. Salt in the body needs water for metabolism, so too much salt intake will lead to edema, so reduce salt intake during exercise. This is because salt plays an important role in water balance and cell osmotic pressure. Excessive salt in the body will lead to water retention in the muscle, which will have a certain impact on the clarity of muscle fibers observed on the skin surface. It's best to eat less salt for good fitness. The more specific reasons are as follows.

1. Salt is difficult to digest in the body. After the human body meets the basic needs of the human body, the metabolizable salt still needs excessive water to digest, which will lead to a problem, namely edema. Too much or too little salt is harmful to human body. If you eat too much salt for a long time, it is more likely to lead to hypertension, heart disease and even edema.

2. When salt enters the body, the water in the body begins to lose, the salt in the body is exhausted, and the blood vessel capacity increases, which is not conducive to fitness exercise. The main component of salt is sodium, and sodium is an appropriate amount of ions, which can adjust the acid-base balance of the body. But if people eat too much, they need to drink too much water to adjust the ion concentration of the body, so that people's blood volume will increase.

Many people know that the human body must supplement salt, but there is a lot to pay attention to, that is, salt intake. The total content of salt in adults is about 1g/kg body weight, of which 50% salt plays a decisive role in cell osmotic pressure, water balance and acid-base balance.

To sum up, the salt content of most diet meals is far from the normal function of the human body in a day, especially on the basis of a certain amount of exercise. Due to the usual fitness training, the body will sweat and lose a lot of salt, especially pay attention to salt supplementation! However, because the contradiction has two sides, we should also pay attention to controlling the total intake of sodium while ingesting sodium, otherwise it will hinder the effect of fitness exercise.
