1. Beta Carotene

Beta carotene is a powerful antioxidant that has several health benefits, from protecting the lungs against toxins that might cause lung cancer to convert into vitamin A in the body and helps maintain healthy skin.

Furthermore, studies have shown that ex-smokers who consumed beta carotene daily were found to have a lower risk of both lung and stomach cancers. Apart from carrots, you can also find beta carotene in spinach, kale, and sweet potatoes.
