(07-12-10) High levels of natural plant antioxidant alpha-carotene are associated with fewer deaths from all causes

(NaturalNews) Picture this: a chemical is discovered that has amazing health-
protecting powers. In fact, if a person consumes enough of the potent life
guarding compound, his or her chances of dying from heart disease, cancer or
any other reason will plummet for many, many years into the future.

Sound like a futuristic drug out of a sci fi story? It's not. Instead, it's a
natural compound available right here and right now -- the antioxidant alpha-
carotene, produced by plants.

In a large study of over 15,000 adults, Centers for Disease Control (CDC)
scientists found that high blood levels of alpha-carotene were associated with
a significantly reduced risk of dying over a 14 year period. The research was
just published in the on-line edition of the Archives of Internal Medicine.

There are several forms of carotenoids, including beta-carotene and lycopene
as well as alpha-carotene. Alpha-carotene is very similar to beta-carotene but
research has shown it may be more effective at preventing or blocking the
growth of cancer cells in the brain, liver and skin, according to the CDC
scientists.

"Moreover, results from a population-based case-control study of the
association between the consumption of fruits and vegetables and risk of lung
cancer suggest that consumption of yellow-orange (carrots, sweet potatoes or
pumpkin and winter squash) and dark-green (broccoli, green beans, green peas,
spinach, turnips greens, collards and leaf lettuce) vegetables, which have a
high alpha-carotene content, was more strongly associated with a decreased risk
of lung cancer than was consumption of all other types of vegetables," the
authors of the study noted in their paper.

Chaoyang Li, M.D., Ph.D., of the CDC and colleagues investigated the
relationship between alpha-carotene and the risk of death among 15,318 adults,
all age 20 or older. The research subjects were participants in the Third
National Health and Nutrition Examination Survey Follow-up Study and all had
medical exams and gave blood samples between 1988 and 1994. Then researchers
followed the study volunteers through 2006 to find out which of them died and
how.

By the end of the study, 3,810 participants were no longer alive -- but the
risk for dying was far lower in the people who had the highest levels of alpha-
carotene in their blood. In fact, as the level of alpha-carotene went up, the
risk of dying went down dramatically.

For example, compared to people with blood alpha-carotene levels between 0 and
1 micrograms per deciliter, those with concentrations of alpha-carotene between
4 and 5 micrograms per deciliter had a 27 percent lower risk of dying. And when
blood levels of the antioxidant reached 9 micrograms or higher, there was
stunning, almost 40 percent lowered chance of death.

What's more, higher alpha-carotene concentrations were linked with a lower
risk of dying not only from cardiovascular disease or cancer, and from all
other causes. The researchers noted in their paper that these data support
increasing fruit and vegetable consumption as a way of preventing premature
death and suggest a need for more clinical research into the health benefits of
alpha-carotene.
