To find foods rich in carotenoids, just look for richly colored red, yellow, orange and dark green fruits, vegetables and herbs. This will lead you right to alpha and beta carotene, lutein, lycopene and zeaxanthine — to name just a few of more than 600 known types of carotenoids found in foods of plant origin.
New animal studies explain why supposedly healthy supplements like beta-carotene could exacerbate a dread disease.

They're best known for supposedly helping us to see in the dark.

The OSU researchers weren't suggesting people forego eating foods high in beta-carotene. So go ahead and enjoy your vitamin A supplements (within reason) and eat as many carrots as you like. You can’t eat your way to beta-carotene toxicity, even if you are Bugs Bunny.
Astaxanthin (pronounced “asta-ZAN-thin”) is a naturally-occurring carotenoid found in algae, shrimp, lobster, crab and salmon. Carotenoids are pigment colors that occur in nature and support good health. Beta carotene, for example, is orange. Astaxanthin, dubbed the “king of the carotenoids” is red, and is responsible for turning salmon, crab, lobster and shrimp flesh pink.
