Role of nutrients in combating infection

The role of nutrients in infectious diseases is crucial to developing the human immune system starting from the embryonic stage. Nutrition and infectious diseases have been linked intricately. There are high chances of adverse effects on the normal development of the immune system if the food is deficient in required dietary allowances for a more extended period. Thus, inviting different infectious diseases like bacterial, parasitic, viral infection, etc. This correlation has been found in various studies and has been closely associated with malnutrition which in turn causes a vicious cycle. Moreover, the risk of infectious diseases increases due to overnutrition or undernutrition that further amplifies the severity of infection. Furthermore, the body becomes weak to fight against infection, which reduces vitamins and minerals and disturbs the metabolism of lipids and carbohydrates. Among all this, the only controllable things are the nutritional factors that can govern the prolongation of life span smoothly.
