Carrots, popular vegetable with a rich source of Beta Carotene
Beta carotene, found in carrots and other orange vegetables, are potent antioxidants that can help reduce your risk of various forms of temporary illnesses and serious chronic diseases. Carrots and carrot juice benefit the immune system by helping to defend the body from free radical damage, harmful bacteria, viruses, and inflammation.
The human body converts beta carotene into vitamin A (retinol). Excess vitamin A is toxic. Vitamin A toxicity can occur if you consume too many supplements. The advantage of getting Beta Carotene from food is that the body only converts it into Vitamin A as much as it needs. Therefore, it is recommended to obtain Beta Carotene from your diet, to avoid Vitamin A toxicity.
Beta carotene has long been known to be an immune booster, and studies have shown that Beta Carotene Appears to be beneficial for an individual with the compromised immune system, and does not appear to overstimulate the immune response of healthy adults.
Beta Carotene may be particularly helpful for the immune system of the elderly. This is because elderly people experience a significantly higher risk of death from infectious diseases than the general population. This apparent susceptibility to infection in the elderly has been attributed to a decline in immune function.
