What is the relationship between
nutrition and immunity?

In addition to environmental, exercise, sleep and other factors that affect immune function, nutrition and immune function are closely related.

Protein: Protein is the raw material that constitutes the immune system, and it is essential to maintain the integrity of the immune system. Bone marrow is the place where immune cells are made. It is called the "soldier's processing factory". If a factory does not have raw materials, it will not produce products. Protein is the raw material of the bone marrow factory, and various immune organs and immune molecules are composed of protein. The most important immune substance in the intestine is glutamine. Insufficient glutamine can easily lead to enteritis and diarrhea. Glutamine is converted from glutamate, which is derived from protein.

Vitamin C: Vitamin C can promote the production of interferon and antibodies, and can activate immune cells. Therefore, it is easy to get sick, so if you want to improve immunity, vitamin C is essential.

Vitamin A: Vitamin A is called "epithelial vitamin" and "immune vitamin". Vitamin A is an important nutrient for maintaining the health of skin and mucous membranes, and skin and mucous membranes are the body's first line of defense. It is like the Great Wall to resist external invasions.

Vitamin B family: Vitamin B6, folic acid and pantothenic acid are all related tothe formation of antibodies. Lack of B

Iron: Iron can promote the production of antibodies and improve immunity.
However, iron should not be excessive, as excessive iron will suppress immune function.

Zinc: The thymus is an important immune organ in the immune system, and the thymus will shrink when it is lacking in zinc. The thymus gland is equivalent to a training ground, and the bone marrow is like a "soldier factory". After the soldiers (immune cells) are manufactured, the thymus gland trains them into a "navy, army, and air force" to make it powerful in combat. Lymph nodes are equivalent to the battlefield, destroying enemies (bacteria, viruses, etc.) one by one. Zinc deficiency can lead to a decline in immunity. In addition, garlic, echinacea, propolis, etc. all have anti-bacterial, anti-inflammatory, and immune-enhancing effects.
