A study report just published by a Harvard University research team has again confirmed the health benefit of carrot on human eye sight. They prevent eye damage.
The team studied over 100, 000 adults aged over 50 years for a period of 25 years; this is due to carotenoids which carrots contain. The study found that those who consumed high amount of alpha and beta-carotene which carrots contain reduced the risk of Advanced Macula Degeneration by about 25-35 percent, Even if the condition is already present, it reduced the progression.
Carotenoids are also present in eggs, leafy vegetables and sweet potatoes. The known carotenoids are lutein, zeaxanthin, alpha-carotene and beta-carotene.
Carotenoids fight free radicals in the eye macula and so prevent damage.
