Eating vitamin A foods is an excellent way to boost your overall health and protect against chronic diseases.
Vitamin A is a general term for a number of important water-soluble vitamins, as well as some provitamins, such as beta-carotene. While retinol is the source of vitamin A found in animal tissues, various carotenes can be found in vegetables, fruits, and other food, which can then be converted into retinol within the body. 
Having enough vitamin A in your diet is important for immune system health, as well as your vision, skin, and respiratory health. Vitamin A deficiencies are also very dangerous for pregnant mothers, so eating enough vitamin A food is critical no matter who you are!
