Found in carrots, sweet potatoes, and green peppers, among other foods, this antioxidant is converted in the body to vitamin A and is important for helthy vision, a functioning immune system, and good skin.
But the evidence isn’t really there to recommend it for staving off cancer or other diseases.
A 2004 study found that supplements might actually raise the risk of lung cancer in smokers.
More recent research in the Journal of the National Cancer Institute also linked excessive beta-carotene intake through supplements with higher risk of lung cancer and heart disease, althou.gh more research is still needed.
Bottom line: Skip the supplements if you’re a smoker, and try to get your beta-carotene from fruits and veggies, whether you smoke or not.
