Association STUDY DEMONSTRATES PECANS A CONSISTENT,
RICH SOURCE
OF THE BENEFICIAL ANTIOXIDANT VITAMIN E
ATLANTA (July 26, 2002) - The
pecans have it! Vitamin E that is, says researchers from
the University of Georgia (UGA). In fact, no matter the variety
or the region of the U.S. where the pecans are grown, the
vitamin E content of pecans remains abundant and constant,
notes the study published in the most recent issue of the
highly respected Journal of Food Science. "This study
helped to demonstrate that basically all pecans are created
equal when it comes to this important antioxidant," says
Dr. Ron Eitenmiller, a food scientist with the UGA College
of Agricultural and Environmental Sciences who conducted
the study using samples from two different years, collected
from several states. Eitenmiller's analysis of the
samples found that the vitamin E content was quite stable,
regardless of the year, variety and region. He remarks, "This
work shows that pecans are not only a really good source
of vitamin E, they are also a consistent source." Pecans contain both the alpha
and gamma tocopherol forms of vitamin E, notes Eitenmiller.
While the alpha tocopherol form of vitamin E has been most
widely studied for its health benefits, researchers are starting
to pay closer attention to the gamma form of tocopherol as
well, according to Sue Taylor, R.D., director of nutrition
communications for the National Pecan Shellers Association. "Vitamin E is the
primary antioxidant we use," Eitenmiller says. "It
protects our bodies when chemical reactions produce oxidation
in the body which can be dangerous. Antioxidants in essence
serve as a tool that inhibits oxidative stress that can
be detrimental to many cellular functions." Vitamin E comes from plant materials
and isn't produced by our bodies. "We have to get vitamin
E from our diet because our bodies don't produce it," says
Eitenmiller. "The major sources are edible oils like those from pecans,
other tree nuts, peanut products, soybeans, liquid vegetable oils and those
kinds of foods." The UGA study found pecans have total vitamin E levels
similar to those in almonds, pistachios and walnuts, and higher amounts than
cashews, macadamia nuts and dry roasted peanuts. "But vitamin E isn't the
only good quality pecans possess," notes Taylor. She
adds that pecans are a good source of fiber and plant sterols
and that nearly 60 percent of the fat found in pecans is
monounsaturated fat and, approximately another 30 percent
is polyunsaturated fat. Pecans also contain over 19 vitamins
and minerals in all, including vitamins E and A, folic acid,
calcium, magnesium, copper, phosphorus, potassium, manganese,
several B vitamins and zinc. "Recent clinical
research studies evaluating the impact of pecans on serum
cholesterol have found pecans can significantly help lower
blood cholesterol when consumed as part of a heart-healthy
diet," Taylor adds, " and the latest significant
study from Harvard published in the prestigious Archives
of Internal Medicine found that men who ate the most nuts
had the lowest risk of sudden cardiac death." Perhaps that is why editorial
commentary in the Journal of Food Science states, "So
enjoy pecans in significant quantities, and use them in food
products - they are good for the heart, and taste good, too!" |
