  • It keeps under control the cells of the body to ensure that they are not abnormal or degenerating.

Each spring, as the environmental temperature changes, the immune system gets weaker and all kind of sicknesses can occur. To protect our body and boost our immune system, we should do a couple of things, such as:

Undernourished people or, on the contrary, the obese people are at greater risk from infections. For example, low calorie diets of 1200 kcal or less per may reduce immune function.
