ESSENTIAL FATTY ACIDS. . .
by PCRM
The body can synthesize
some of the fats it needs from the foods you eat. However,
two essential fatty acids
cannot be synthesized in the body and must be taken
in the diet from plant foods. Their names—linoleic and
linolenic acid—are not important. What is important is
that these basic fats are used to build specialized fats
called omega-3 and omega-6 fatty acids. Omega-3 and
omega-6 fatty acids are important in the normal functioning
of all tissues of the body. Deficiencies are responsible
for a host of symptoms and disorders including abnormalities
in the liver and kidney, changes in the blood,
reduced growth rates, decreased immune function,
and skin changes including dryness and scaliness.
Adequate intake of the essential fatty acids results
in numerous health benefits. Prevention of atherosclerosis,
reduced incidence of heart disease and stroke, and relief
from the
symptoms associated with ulcerative colitis, menstrual
pain, and joint pain have also been documented. While
supplements and added oils are not typically necessary
in the vegetarian diet, good sources of omega-3 fats
should be included daily. Alpha-linoleic acid (ALA),
a common omega- 3 fatty acid, is found in many vegetables,
beans, and fruits. More concentrated sources can be found
in oils such as canola, flaxseed (linseed), soybean,
walnut, and wheat germ. Corn, safflower, sunflower, and
cottonseed oils are generally low in ALA. Omega- 6 fatty
acids, such as gamma-linolenic acid, can be found in
more rare oils, including black currant, borage, evening
primrose, and hemp oils.
Plant Foods Rich in ALA
- Green leafy vegetables (perslane, lettece, broccoli,
spinach, etc.)
- Legumes (navy, pinto, or limabeans, peas or splitpeas,
etc.)
- Citrus Fruits
Fish
oils have been popularized as an aid against everything
from heart problems to arthritis. The bad news
about fish oils is that omega-3s in fish oils
are highly unstable molecules that tend to decompose
and, in the process, unleash dangerous free radicals.
Research has shown that omega-3s are found in a more
stable form in vegetables, fruits, and beans. Whether
you are interested in promoting cardiovascular
health, ensuring the proper growth and development
of your child, or relieving pain, a vegetarian
diet rich in fruits, vegetables, and legumes can help you
achieve adequate intake of the essential fatty acids. Adding
flaxseed oil to your salad or grinding flax seeds for your
breakfast cereal are simple ways to incorporate extra omega-3
fatty acids to your diet.
