Longer life associated with higher alpha carotene levels.

An article appearing in the Archives of Internal Medicine reports the discovery of researchers at the Centers for Disease Control and Prevention of an association between higher serum levels of the carotenoid alpha-carotene and a lower risk of dying over a 13.9 year average period. *

Chaoyang Li, MD, PhD, and colleagues evaluated data from 15,318 adults who enrolled in the Third National Health and Nutrition Examination Survey Follow-up Study between 1988 and 1994. The participants were followed through 2006, during which the causes of deaths that occurred were recorded.


Among participants whose alpha-carotene levels were highest at 9 or more micrograms per deciliter, there was a 39% lower adjusted risk of dying from any cause compared with those whose levels were lowest.

"These findings support increasing fruit and vegetable consumption as a means of preventing premature death," the authors conclude.

Editor's note: To obtain high levels of alpha carotene you should include the following in your diet: pumpkin, carrots, sweet potatoes, cantaloupe, spinach, broccoli, green beans, barley, oats, and plant-based foods.
