Beta-Carotene Protects Against Heart Attack

BOSTON--In a study reported in the July issue of the Journal of Nutrition (135:1763-69), researchers from Harvard University and the University of Costa Rica reported intake of fruits and vegetables rich in beta-carotene are inversely related to risk of myocardial infarction. Adipose levels of carotenoids and tocopherols were measured in Costa Rican subjects who had experienced their first heart attack. Those in the lowest quintile of beta-carotene levels showed a significantly higher risk of heart attack, compared to those in the highest quintile. Conversely, lutein and zeaxanthin in adipose tissue or the diet were positively associated with risk of heart attack.
