Healthy Fat--CLA
If, like millions of Americans, you think that the road to healthy
eating is paved with all things “lite” and low fat, think again.
Scientists are discovering that Mother Nature’s best medicine just may
be red meat and dairy. Studies indicate that our well-intentioned
efforts to reduce the amount of fat in our diets may also be reducing a
primary source of conjugated linoleic acid – a potent, cancer-fighting
essential fatty acid and a nutrient presently being researched for its
potential to promote metabolic function and decrease body fat. And
that’s not all. Scientists are finding that fighting cancer and obesity
is just the beginning of what this hot, new gem on the health and
wellness scene can do.
Conjugated linoleic acid (CLA) first
came to public attention in 1988, when a University of Wisconsin
researcher discovered its cancer-fighting properties in a study of rats
fed fried hamburger. Today, scientists are finding that even low
concentrations of CLA are more strongly anti-carcinogenic than other
fatty acids — particularly in inhibiting breast and prostate tumors, as
well as colorectal, stomach and skin cancer, including melanoma.
Increasing
your body’s level of CLA has also been shown to decrease fat and
enhance muscle growth. Compelling evidence, including the studies
below, indicates that CLA can promote increased metabolic function and
reduce body fat.
* A recent study at the Louisiana State
University confirmed that feeding male mice a CLA-enriched diet for six
weeks resulted in 43 percent to 88 percent lower body fat, especially
in the abdominal area.
* A study performed at the University of
Wisconsin-Madison concluded that mice supplemented with only .5 percent
of CLA showed up to 60 percent lower body fat and up to 14 percent
increased lean body mass compared to controls.
* A pioneering
Norwegian human study found that participants who added CLA supplements
to their diet lost up to 20 percent of their body fat in three months
without changing their diet, while the control subjects on the average
gained a slight amount of body fat during the same period.
But
the myriad health benefits of CLA don’t stop there. Initial studies
show that CLA may also lower cholesterol, strengthen the immune system
and enhance insulin sensitivity — a significant breakthrough in the
overall treatment of Type II diabetes.
Emphasis towards
eliminating red meat and dairy from the American diet means that CLA
may not be readily available to those focused solely on fresh fruits
and vegetables, whole grains and low fat proteins. CLA is a fat and is
found in whole-fat milk, butter, cheese and high-fat red meat such as
beef and lamb — most specifically those products from grassfed
ruminants, the richest known source of CLA. Because of lactose
intolerance or any number of dietary concerns, some may prefer to
ingest CLA in a supplement form. A dosage of 3g a day has been used in
most of the studies, but even 1,000 mg a day is considered to be
effective for most people. CLA is especially effective when combined
with Chromium Picolinate.
