Carotenoids are yellow, orange, and red pigments found in plants. Out of over 600 carotenoids found in nature, only six, i.e. β-carotene, lycopene, lutein, zeaxanthin, α-carotene, β-cryptoxanthin, are absorbed in quantity into the body. Only three (β-carotene, α-carotene and β-cryptoxanthin) can be converted to vitamin A in the body. Lutein and zeaxanthin are highly concentrated in the macular pigment of the retina, playing an important role in vision. Lutein supplementation increases visual function in adults. Emerging science links lutein status with cognitive function.
Because serum carotenoids have been inversely associated with cardiovascular disease (CVD) risk, Wang and colleagues assessed carotenoid intakes (2-24h recalls) and serum carotenoid concentrationsRead More »
