Pecans Contribute
to Heart Health and Disease Prevention
As you know, being a quality vitamin site, we can't say
enough about the positive attributes connected with antioxidants (which
are prevalent in pecans), but this new finding is awesome.
A recent research study from Loma Linda University (LLU)
reveals that the organically occurring antioxidants in pecans indeed
help contribute to heart health and aid disease prevention. These new
and exciting findings were published in the January 2011 addition of The
Journal of Nutrition. Pecans actually contain different forms of the
antioxidant vitamin E (known as tocopherols) as well as several phenolic
substances that portray antioxidant likeness. Pecans are very rich in
one form of vitamin E known as gamma-tocopherols. The new study shows
that after pecans are consumed, these same gamma-tocopherol levels in
the body doubled and unhealthy oxidation of LDL (the bad) cholesterol in
the blood lessened by as much as one third. Oxidized LDLs may also
contribute to swelling in the arteries and put people at a higher risk
of cardiovascular issues and disease.
Tests show (in this study) that
ingesting pecans will amplify the amount of healthy antioxidants in the
body. This protective effect is central in helping to put off expansion
of a variety of diseases such as cancer and heart disease. We all know
that heart disease and cancer are extremely prevalent and both are
devastating diseases.
The study findings are from a
research project intended to further look into the health benefits of
pecans. The study investigated biomarkers in blood and urine samples
from sixteen women and men that were aged between 23-44 years old. Each
participant in the study consumed a sequence of 3 different diets
(consisting of whole pecans, pecans mixed with water, or a control meal
of the same nutrient value). These pecan meals included approximately 3
ounces of pecans each. Study samples were taken before these meals and
at intervals up to 1 day after consumption of the meals.
Following the test meals made of
whole pecans and water mixed pecans, researchers established that
amounts of gamma-tocopherols (vitamin E) in the body doubled within 8
hours after both meals were consumed. That is remarkable. Among other
helpful findings, researchers were able to note that following the
“whole pecan” meal, oxidized LDL cholesterol reduced by 30% after only 2
hours, peaked at 33% after 3 hours, and 26% after the same 8 hours
period.
This study is another reason to love
pecans for more than making a great pie or chocolate covered delicacies.
Pecans are healthy food. Research showing pecan contain anti-oxidants is
nothing new. But this study is notable in the fact that it shows these
anti-oxidants are actually absorbed in the body and support a protective
outcome against some very high profile diseases.
Eat your pecans people!
Worth mentioning:
Research from LLU previously
published in the same well known nutrition journal showed that a
pecan-fortified diet decreased levels of LDL cholesterol by nearly 17%.
This is over twice the American Heart Association's Step I diet (this is
the diet used as the control diet in that research study). Also, the
pecan-fortified diet decreased total cholesterol levels by more than 11%
(still twice as much as the Step I diet).
