American nutritionist Erin Palinski-Wade said The Daily Mail says that cravings for more salty foods may be due to a lack of sodium in the body due to intense high-intensity training.
The doctor explained that when intense exercise is performed, a large amount of water is removed from the body through sweating. People who exercise often compensate for their lack of fluids by drinking plenty of water and other beverages. However, in the process of sweating, the body loses not only fluid but also sodium.
Sodium is an active component of water-salt metabolism in the body. It is necessary for the transmission of nerve impulses and the formation of bone tissue, but its main function is to maintain the volume of extracellular fluid, which determines the amount of blood in circulation and blood pressure. When replenishing fluid reserves during training, the body does not receive water-retaining sodium, which leads to disturbances in water-salt metabolism.
Sodium deficiency becomes worse if a person trains hard on a regular basis. Therefore, some physically active people (especially beginners) experience an increased craving for salty foods, which help retain fluid in the body and prevent dehydration.
