How does food help in improving immunity?

Food helps improve immunity by providing the essential nutrients the immune system needs to function properly. Proteins help build and repair body tissues, while vitamins such as Vitamin A, Vitamin C, Vitamin D, and Vitamin E, along with minerals like zinc, iron, and selenium, support the production and activity of immune cells.

A balanced diet that includes fruits, vegetables, whole grains, pulses, milk, eggs, nuts, seeds, and healthy fats helps the body fight infections, recover from illness, and maintain overall health. Drinking enough water and eating a variety of nutrient-rich foods also strengthens the body's natural defence system.
