Vitamin A – The immune booster
Apart from helping you stay young and maintaining a good vision Vitamin A has a lot more to do with body’s natural immune system; Vitamin A deficiency can make you susceptible to Infectious Diseases.
Innate immunity is body’s first line of defence against incoming virus, bacterias and pathogens. The idea of using the immune system to help the body fight disease has been in existence for some long time; vaccines, which allow the body to remember disease-causing pathogens, provides an excellent example.
A strong correlation with Vitamin A deficiency and weak immunity has been established long back(1). Animal studies had proved Vitamin A deficiency can impair body’s immune response to Respiratory Viral Infections (2).
While nutritional supplements are prescribed for Vitamin A deficient individuals, maintaining a good dietary sources can help us stay away from infections and live healthy.
Some best dietary source of Vitamin A includes;
- Spinach and all green leafy Vegetables.
- Sweet potatoes
- Oily fish
- Egg yolk
- Cheese and butter.
