Counting health benefits of Peanut Butter
The peanut, Arachis hypogea,
is really a legume - same as a bean or pea. Peanut butter makes delicious
spread for breads, waffles, bagels, toast, crackers, apple slices, celery, or
carrots. Spread it on plain or make some of the spreads at home. Store them in the
refrigerator for up to a week.
Nutritive Analysis
The total calorie content in
100 grams of peanut butter is 589Cal.
The calorie breakdown for peanut butter is:
This means that the vast
majority of calories come from
fats, most of the fats contained are however
monounsaturated, and have been shown to
improve the
cholesterol
profile by lowering "bad" LDL cholesterol. The
unsaturated fat content in peanut butter helps reduce the risk of
heart disease
by 25% (if you eat 1oz per day).
Peanut butter contains fairly high quantities of dietary
fiber, amounting to
about 8%, which again helps in regulating both blood cholesterol and blood sugar
levels.
Dietary fiber has also been shown to significantly reduce the risk of
colo-rectal
cancer (which is among the most common causes of death by
cancer in civilized
countries) and atherosclerosis (another common disease in the U.S. and Europe).
Proteins are present in high amounts (about 24% in weight), together with
very important micro-nutrients such as
Vitamin E,
Vitamin B3 and large amounts
of beneficial minerals such as
iron,
magnesium,
potassium,
copper and
calcium. Vitamin E is one of the most powerful liposoluble
antioxidants, shown to
significantly reduce the risk of cancer and cardiovascular diseases; Vitamin B3
(also known as Niacin) is a water-soluble vitamin that aids in the
recovery of cell DNA damage (thus protecting from cancer) and in improving
sexual bodily functions by assuring the proper secretion of sexual hormones.
The
minerals peanut butter contains are in variable amount (raw peanut butter
with crushed skin contains much higher amounts than refined "nut-only" butter):
iron is essential for the correct functioning of your red blood cells, while
calcium promotes healthy bones and shields against
muscle spasms.
Although not among the richest foods in potassium, peanut butter still contains
fairly good amounts of it, and research has indicated that diets rich in
potassium reduce the risk of
hypertension (bananas
are, however, a better source of potassium, try making a banana and peanut
butter sandwich!).
The most unique property of
peanut butter, though, is its high content in Resveratrol, a substance that's
been shown to have very strong anti-cancer properties. In a randomized, cross-over, double-blind study involving 22 subjects, a high
monounsaturated diet that emphasized peanuts and peanut butter decreased the
risk of cardiovascular diseases by 21% compared to the average American diet.
Another peculiar substance contained in peanut butter is p-coumaric acid,
a polyphenol that helps combat oxidative stress (a syndrome believed to cause
some neurodegenerative and cardiovascular diseases). Scientific sources such as
the Food Chemistry concluded that roasting peanuts leads to a higher
content in p-coumaric acid by as much as 22%.
Preventing Gallstones and Alzheimer
In a test conducted during 20 years, on 80,000 female subjects by the Nurses'
Health Study, it was observed that women who eat least 1 ounce of nuts, peanuts
or peanut butter each week have a 25% lower risk of developing
gallstones. This
quantity can easily be reached by eating one peanut butter sandwich per week!
According to the Journal of Neurology, Neurosurgery and Psychiatry,
the niacin contained in peanuts, when eaten regularly, provides protection
against Alzheimer's disease.
In addition to this, peanut butter contains much higher quantities of
antioxidants than apples or carrots.
Preventing weight gain
All things considered, peanut butter deserves a place in
a healthy diet for
the vast range of important
nutrients it contains.
Because of its high
fat and
caloric content, however, some doctors argue that
obese people should consume only little amounts of it: there is a lot of
controversy about this, and there are many studies claiming that eating nuts
more than twice a week actually reduces the risk of
weight gain. One of these studies was published on the journal
Obesity, it involved
8865 adult men and women in Spain and was carried out during a 28-month period:
the subjects who ate nuts at least twice a week were 31% less likely to gain
weight (> 5kg) than the others.
Note: Please keep in mind this is not medical advice, you should consult your
doctor before adding peanut butter to your diet (especially in light of some
people being highly allergic to peanuts).
