The pecan is a
natural high-quality food that is wholesome, healthy, and delicious.
Pecans are low in sodium, contain no cholesterol, and are high
in protein and unsaturated fats. Pecans are a good source of calcium,
iron, phosphorus, potassium, and magnesium. North Carolina pecans
are versatile and can be purchased in volume during harvest for
year-round use.
90% of the fats in pecans are unsaturated (about 60% monounsaturated/30%
polyunsaturated).
A serving (30g) of pecans provides about 25% more oleic acid than
a serving (one tablespoon) of olive oil.
Pecans are cholesterol-free.
Pecans are sodium-free.
Pecans are fiber-rich.
Pecans are a valuable plant protein source.
Pecans have more than 19 vitamins & minerals.
They are an excellent source of gamma tocopherol, an important
type of vitamin E.
They contain concentrated amounts of natural plant sterols, touted
for their cholesterol-lowering ability.
Pecans contain a variety of phytochemicals
Nuts are recommended by the American Heart Association and U.S.
Dietary Guidelines as a desirable source of heart-healthy unsaturated
fat.
Pecans can double the cholesterol-lowering
effectiveness of a traditional heart-healthy diet.
According to a study published in The Journal of Nutrition, September
2001, an 8-week study at Loma Linda University found that a 'pecan'
diet (which consisted of replacing 20 percent of the calories from
the American Heart Association's Step I diet foods with pecans)
lowered total cholesterol by 11.5%. The Step I diet lowered total
cholesterol by 5.2%. In addition, the pecan diet increased the HDL
or good cholesterol, whereas the Step I diet decreased HDL unfavorably.
Triglycerides also were significantly lower with the pecan diet.
Although the pecan diet contained more fat (39.6%) than the Step
I diet (28.3%), participants did not gain weight.

Pecans raise vitamin E levels and may support
prostate and intestinal health.
Further analysis of the participants in the above study revealed
that a pecan-enriched diet significantly raised blood levels of
gamma tocopherol compared to the Step I diet. This is due to the
high amounts of naturally occurring gamma tocopherol (a unique form
of vitamin E) in the pecans. Gamma tocopherol is an important antioxidant
nutrient and studies have shown that it may benefit intestinal health
and have a protective effect against prostate cancer.
This research was presented at the April 2001 Experimental Biology
meeting and published in the FASEB Journal (http://www.fasebj.org/).

Pecans increase fiber
and nutrient intake.
Researchers at Texas A&M University found that a heart-healthy
diet containing pecans can help control specific biomarkers of heart
disease risk as effectively as the American Health Association Step
I diet. They also found that the pecan-rich diet significantly increased
participants' levels of dietary fiber, thiamin, magnesium, copper,
and manganese and actually changed copper and magnesium intakes
from inadequate (on the AHA diet) to adequate (on the "pecan" diet).
All of the participants had already been eating a relatively low-fat
diet. For this study, they were placed on either the Step I diet
or a higher-fat, pecan-based diet.
This information was presented at a May 2001 American Heart Association
Conference on Arteriosclerosis, Thrombosis and Vascular Biology.
Pecans: a concentrated source of natural plant
sterols.
Researchers at the University of Georgia have determined that
plant sterols are found naturally in pecans in concentrated amounts.
90% of those pecan sterols are in the form of beta-sitosterol, which
has been cited as a food component that competes with the absorption
of cholesterol in the body and thus has the ability to lower blood
cholesterol levels.
Adding pecans to your diet can lower "bad"
cholesterol.
A study at New Mexico State University (NMSU) has found that pecans
offer something even more important than great taste and versatility
- a positive impact on health. The research, conducted by NMSU's
Wanda Morgan, Ph.D., shows that adding pecans to a self-selected
diet lowers LDL or bad cholesterol levels by 6%; total cholesterol
levels were lower as well. In this study, 19 men and women with
normal blood lipid levels were divided into two groups, one of which
served as the control group and ate its regular diet for eight weeks.
Subjects in the test (pecan-eaters) group, however, supplemented
their diets with three-fourths of a cup of pecans every day. Even
though the test group ate more total fat each day, monounsaturated
and polyunsaturated fat, than those who did not eat pecans, test
subjects lowered their levels of bad and total cholesterol and did
not gain weight. "The research shows that we don't have to be afraid
of the fat in pecans," says Dr. Morgan. "Pecans can be a part of
a balanced and varied diet."
This encouraging news about the positive impact of pecans on heart
health was published in the March 2000 issue of the Journal of the
American Dietetic Association (http://www.adajournal.org/).
