Natural Health News – Increased intake of lutein can not only have a beneficial role live in the macula of the eye, but can also help combat systemic inflammation, according to a new study.
macula is a yellow spot of about five millimeters in diameter on the retina. A thin macular pigment can allow the blue light through and destroy the cells. Maintaining high levels of both carotenoids, and therefore the macular pigment, it is a valid maintaining eye health approach and reduce the risk of diseases such as AMD.
The new study, published in Acta Eye Care adds to a growing body of science that supports the vital role of carotenoids lutein and zeaxanthin for eye health. These compounds are the only carotenoids capable of filtering harmful blue light that can damage cells in the eye, the rods and cones.
The researchers recruited 70 people with early stage AMD and randomly assigned them to receive 10 mg per day of lutein or placebo for one year.
The results indicated that supplementation with 10 mg of lutein reduced levels of a substance in the body called sC5b-9, a marker of systemic inflammation, compared to placebo.
The link between lutein and eye health by researchers at Harvard University, who found a relationship between intake of rich carotenoids in foods, especially vegetables were first reported in 1994 greens like spinach, and a significant reduction in AMD.
This study is the first to show that an increased dietary intake of lutein reduces the plasma level of sC5b-9 accordign scientists from Maastricht University Eye Clinic in the Netherlands and the University of Manchester in England.
Because of the relationship between systemic inflammation and the course of AMD added that “lutein supplementation may be considered as a potential prevention and treatment for AMD.”
