The benefits of carotenoids are as follows.... A good fighter of infections and diseases, being vital to a healthy immune system. It can also prevent heart disease. It's also believed to prevent diabetes and reduce the complications from it. Various forms of cancer can be reduced, including breast cancer.
Eyesight is protected and the ageing process of the brain is slowed too.
Beta carotene is the star player of the carotenoid family. Why? Because the body is able to split a molecule of beta-carotene in half to form two molecules of vitamin A. It is considered a very safe form of vitamin A because, cleverly, the body only performs this splitting when required.
It has been discovered that beta-carotene is a very effective antioxidant,especially in protecting against the reactive oxygen species called singlet oxygen.
If you stick to a diet with varied colourful fruits and vegetables, you probably get plenty of carotenoids. People at risk of certain conditions may benefit from extra amounts of some.
Finally, in a U.S. study scientists looked at the effects of beta-carotene (which the body converts into vitamin A) supplements taken by men. The results were that those men who took the supplements for 15 years (or longer), have better functioning memory and other brain skills.
This research only goes to provide more evidence that antioxidants can stave off diseases of aging such as Alzheimer's.
