Marigolds contain numerous antioxidant carotenoids that give the petals their bright orange and yellow colors. An antioxidant is a compound that helps protect the cells from damage caused by free radicals, or hazardous molecules. Free radicals are the by-products of normal body functions or environmental factors such as cigarette smoke or pollution. Free radicals can damage cells to the point that they damage DNA, and can lead to disease. High intake of antioxidants helps combat free radical damage. The primary carotenoids in marigolds are lutein and zeaxanthin, often paired together. The Linus Pauling Institute reports that lutein and zeaxanthin are the only antioxidants that are found in the retina of the eye, where they protect the eye from the development of cataracts and macular degeneration.
