Why vitamin A, B, C, zinc, and iron in fruits are essential for the immune system?

The immune system is a network of white blood cells, proteins called antibodies, and some other chemicals. These network members work together to fight viruses and infections.

The first factor in the immune system’s health is vitamin C which contributes to the synthesis of the white blood cells. The deficit in vitamin C results in fewer white blood cells and a weak immune system. The good news is fruits that contain vitamins C are commonly available in all seasons.

Vitamin C supports the production of interferon. Interferons are a particular protein made by cells. Every cell in our body makes and releases two kinds of interferons called alpha and beta, and white blood cells release gamma.

In case of a cell infection with viruses or other germs, body cells send interferon-alpha and interferon-beta as a warning signal to white blood cells. The message triggers them to release interferon-gamma. This interferon fights off the infection.

B6 contributes to producing a specific protein called interleukin-2, which directly involves white blood cells’ actions. Vitamin B6 deficiency also decreases the synthesis of white blood cells, including T cells (kind of blood cells).

Vitamin E, as an antioxidant, plays a significant role in protecting white blood cells.
Vitamin A is another element that also plays an essential role in the synthesis and functions of the two types of white blood cells, B and T, which both possess the ability to fight infections.

White blood cells, specifically lymphocytes, require iron for proliferation and maturation.
The immune system is strengthened by zinc, as zinc activates enzymes that break down proteins in viruses and bacteria, preventing them from spreading.
