The Health Nut
Pecans May Protect the Mind
Eating about a handful of pecans each day may play a role in protecting the nervous system, according to a new animal study published in Current Topics in Nutraceutical Research. The study, conducted at the Center for Cellular Neurobiology at the University of Massachusetts Lowell, suggests adding pecans to your diet may delay the progression of age-related motor neuron degeneration. This may include diseases like amyotropic lateral sclerosis (ALS), also known as Lou Gehrig’s disease.
Natural Antioxidants in Pecans
Naturally-occurring antioxidants in pecans may help contribute to heart health and disease prevention, according to a study at Loma Linda University. The results were published in the January 2011 issue of The Journal of Nutrition.
Pecans contain different forms of the antioxidant vitamin E known as tocopherols, plus numerous phenolic substances, many of them with antioxidant abilities. The nuts are especially rich in one form of vitamin E called gamma-tocopherols. The findings illustrate that after eating pecans, gamma-tocopherol levels in the body doubled and unhealthy oxidation of LDL (bad) cholesterol in the blood decreased by as much as 33 percent. Oxidized LDLs may further contribute to inflammation in the arteries and place people at greater risk of cardiovascular problems.
Pecans also play a role in lowering cholesterol. Clinical research published in the Journal of Nutrition (September 2001) compared the Step I diet (28 percent fat), recommended by the American Heart Association for individuals with high cholesterol levels, to a pecan-enriched (40 percent fat) diet. The results showed the pecan-enriched diet lowered total cholesterol by 11.3 percent and LDL (bad) cholesterol levels by 16.5 percent, twice that of the Step I diet, without any associated weight gain.
The U.S. Food and Drug Administration (FDA) has acknowledged this and related research and approved the following qualified health claim:
“Scientific evidence suggests, but does not prove, that eating 1.5 ounces per day of most nuts, such as pecans, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease.”
