Flaxseed oil and the heath benefits
This is an educational site for anyone looking for
information on fish oil. None of the information is a substitute for

Flaxseed oil is a rich, vegetarian source of omega 3 and omega 6 essential
fatty acids. Essential fatty acids are critical in the production of
prostaglandins. In the body prostaglandins help regulate fat metabolism,
inflammatory response, hormones, as well as the cardiovascular, immune
and central nervous systems. There is some concern by physicians that
modern diets may be too rich in omega 6 fatty acids and deficient in
omega 3's, which can contribute to health concerns.
Flaxseed oil is heart-healthy because it contains alpha-linolenic acid.
Flaxseed itself (ground or whole) also contains lignans, which may have
antioxidant actions and may help protect against certain cancers, though
this is far from certain. Skip flaxseed supplements, though.
Flaxseed oil is derived from the seeds of the flax plant. Flaxseed
oil and flaxseed contain substances that promote good health. Flaxseed
oil is rich in alpha-linolenic acid (ALA), an essential fatty acid that
appears to be beneficial for heart disease, inflammatory bowel disease,
arthritis and a variety of other health conditions. Flaxseed, in addition
to ALA, contains a group of chemicals called lignans that may play a
role in the prevention of cancer. Please see the flaxseed monograph
for further information on this herbal agent.
ALA, as well as eicosapentaenoic acid (EPA) and docosahexaenoic acid
(DHA), belongs to a group of substances called omega-3 fatty acids.
EPA and DHA are found primarily in fish while ALA is mostly found in
flaxseed oil and other vegetable oils. Although similar in structure,
the benefits of ALA, EPA, and DHA are not necessarily the same.
It is important to maintain an appropriate balance of omega-3 and omega-6
(another essential fatty acid) in the diet as these two substances work
together to promote health. These essential fats are both examples of
polyunsaturated fatty acids, or PUFAs. Omega-3 fatty acids help reduce
inflammation and most omega-6 fatty acids tend to promote inflammation.
An inappropriate balance of these essential fatty acids contributes
to the development of disease while a proper balance helps maintain
and even improve health. A healthy diet should consist of roughly two
to four times more omega-6 fatty acids than omega-3 fatty acids. The
typical American diet tends to contain 14 to 25 times more omega-6 fatty
acids than omega-3 fatty acids and many researchers believe this imbalance
is a significant factor in the rising rate of inflammatory disorders
in the United States.
Omega-3 fatty acids have been shown to reduce inflammation and help
prevent certain chronic diseases such as heart disease and arthritis.
These essential fatty acids appear to be particularly important for
cognitive and behavioral function as well as normal growth and development.
