Nutritional diet and health: building an indestructible immune system

The immune system is our body's defense mechanism, which protects us from infection by recognizing and eliminating foreign pathogens. The functions of the immune system include identifying self and non self substances, eliminating harmful microorganisms, and clearing dead or damaged cells. A healthy immune system can effectively combat diseases, including colds, flu, and even more serious health problems.

Vitamin D: Vitamin D is crucial for regulating the immune system and enhancing the response of immune cells. Sunshine is a natural source of vitamin D, and foods rich in vitamin D include fish, egg yolks, and fortified foods.

Iron: Iron is essential for the normal function of many immune cells, and iron deficiency can weaken the immune system. The food sources of iron include red meat, legumes, and fortified grains.
