Low levels of Lutein and Zeaxanthin connected to coronary artery disease

July 25, 2006

In this study researchers at the University Hospital, Linkoping, Sweden performed high performance liquid chromatography (a highly advanced and accurate testing procedure) to analyze the blood of 89 patients with coronary artery disease and compared them with blood samples taken from 50 healthy volunteers. It was found that having low levels of the carotenoids Lutein, Zeaxanthin, and beta-cryptoxanthin significantly increased the risk of developing coronary artery disease. The research appears on line ahead of print in the journal Nutrition, Metabolism, and Cardiovascular Diseases.

Studies show it is not the caffeine which helps decrease the risk of developing diabetes but probably the polyphenols.
