People who consumed the highest levels of the carotenoids lutein and zeaxanthin had a 40 percent lower risk for advanced AMD compared with those who consumed the least, while people who consumed beta cryptoxanthin, alpha carotene, and beta carotene had a 25 to 35 percent lower risk.
Initial and subsequently collected blood samples were analyzed for plasma alpha carotene, beta carotene, beta cryptoxanthin, lutein and zeaxanthin, and lycopene.
In another study, higher blood levels levels of alpha carotene were linked with significantly lower risk of death from all causes, including cardiovascular disease and cancer, according to an article in a recent issue of Archives of Internal Medicine.
