Good Fat #1: Coconut Oil!
Virgin coconut oil is a very stable, saturated fat which
comes from the white meaty part of the coconut fruit. Coconuts come from
coconut palm trees, which grow abundantly in the tropics and subtropics.
The fruit yields a variety of products, all of which are beneficial to
human health.
Coconut is a major source of the medium chain saturated
fatty acids, which are much easier to digest, since no bile from the
gallbladder is needed. If you are just starting out eating more fat, try
beginning with coconut products. They will be easier on your digestive
system.
The health benefits of coconut are impressive. They
include but are not limited to:
better digestion
relief from kidney problems
lowering of high blood pressure
stabilization of blood sugar in diabetics
reduced inflammation
increasing bone strength
The benefits can be attributed to the presence of lauric acid, capric
acid and caprylic acid. These fatty acids are known to be antimicrobial,
antioxidant, antifungal, and antibacterial. These substances help the
body kill pathogenic viruses, bacteria and protozoa.
Lauric acid is a major component of human breast milk, and helps
newborns fight off infections. For this reason, coconut oil has been
added to commercial infant formula so that lauric acid is present to
help newborns survive. Adults can get lauric acid from only three
sources: butterfat, coconut and palm oil.
Here's a recent study that confirms the anti-microbial properties of
coconut oil.
And another study which shows how virgin coconut oil can help children
overcome pneumonia.
Because the oil from coconuts is highly saturated, it gets a pass from
those who believe saturated fat causes heart disease. In reality, the
virgin form of this fatty substance may be one of the most useful to
prevent heart disease because of its antiviral and antimicrobial
characteristics. Coconut consumption helps reduce inflammation in the
body. Recent studies are revealing that inflammation is a major factor
in heart disease.
Prior et al (1981) had shown that islanders with high intakes of coconut
oil do not have high serum cholesterol nor high coronary heart disease
mortality or morbidity. However, when these groups migrated to New
Zealand and lowered their intake of coconut products, their total
cholesterol and LDL cholesterol increased, and their HDL cholesterol
decreased.
Another article published in the Journal of the American Medical
Association stated that when coconut oil was fed as 7% of energy to
patients recovering from heart attacks, the patients had greater
improvement compared to untreated controls, and no difference compared
to patients treated with corn or safflower oils. (JAMA 1967
202:1119-1123; Am J Clin Nutr 1981 34:1552)
More Good Fats: Omega 3 & 6 Fatty Acids
Omega 3 (written as ω-3) fatty acids are a group of
essential fatty acids (EFAs) that are found in seafood and plants.
There are three different ω-3 EFAs: Alpha-Linolenic Acid (ALA), which
can be converted into EPA (Eicosapentaenoic Acid) and DHA (Docosahexainoic
Acid). All essential fatty acids are called polyunsaturated fatty acids
or PUFAs for short.
Because these essential fatty acids cannot be synthesized
by the body, they must be derived from your diet.
There are actually two classes of "essential" fatty acids (EFAs) that the body cannot make:
While both the ω-6 and ω-3 essential fatty acids are vital for health, we only need them in small amounts. In addition, both ω-6 and ω-3 fatty acids should be consumed in equal amounts. The goal that research has determined is optimal is a consumption ratio of is 1:1.
Unfortunately, vegetable oils containing ω-6 fatty acids are widely used
in America, and the standard American diet provides a ratio of at least
10:1. This is unfortunate since ω-3 fatty acids have a very beneficial
effect on the body.
Essential Fatty Acid Functions Essential fatty acids play a role in nearly every metabolic function in the body. One of the most important functions of essential fatty acids is in acting as a parent molecule for a class of hormone like molecules called eicosanoids.
Eicosanoids are among the potent regulators of cellular
function, and they are produced by almost every cell in the body.
Eicosanoids exert a wide ranging and profound effect on your health. Among other effects, they regulate blood pressure, lung function, and blood clotting mechanisms. At any given time, the type of eicosanoids that are dominant within the body depends on the types of essential fatty acids being eaten. In general, since ω-3 fatty acids have an anti-inflammatory effect on the body, eating more ω-3 rich foods results in a higher production and assimilation of anti-inflammatory eicosanoids.
And in opposition, eating more omega-6 fatty acids
produces eicosanoids which have pro-inflammatory properties.
As mentioned, in the last 100 years, the amount of ω-3
polyunsaturated fats in the Western diet has declined, while the
consumption of ω-6 fatty acids has increased due to a rise in the use of
vegetable oils.
The ratio of omega-6 to Omega 3 fatty acid consumption in
the United States has changed from a desirable 1:1 to more than 10:1.
These changes have resulted in an emphasis on omega-6 fatty acid accumulation in our cellular structures, which in turn leads to an overproduction of pro-inflammatory eicosanoids.
A lack of Omega 3 fatty acids is being targeted as a
factor in the rates of heart disease, atherosclerosis, diabetes, cancer,
and mood disorders such as depression and bipolar disorder in modern
culture.
Sources of Omega 3 Fatty Acids Wild caught cold water fish such as salmon, sardines, and halibut are rich sources of w-3 fatty acids. Flaxseeds, canola oil and walnuts are all generally rich sources of the parent Omega 3, alpha linolenic acid (ALA).
Dietary ALA can be metabolized in the liver to EPA and
DHA, but the conversion is limited within the body.
Aging, illness and stress, as well as excessive amounts
of omega-6 rich oils (corn, safflower, sunflower, cottonseed) can all
interfere with the conversion of ALA to EPA and DHA.
Therefore, it is recommended to consume fish and seafood to obtain sufficient amounts of EPA and DHA in your diet. |
