Omega-3 fatty acids are polyunsaturated
fats that have a growing reputation for their health promoting
properties. These healthy fats are abundant in fatty fish, including
tuna, salmon, halibut, and snapper. Flaxseeds and walnuts are also excellent sources.
1. Good for the heart
Research has shown that omega-3 fatty
acids may prevent cardiovascular disease by improving arterial
elasticity. It has been found to lower the risk of arrhythmias (abnormal heartbeats), which can lead to sudden death.
2. Reduce inflammation in the body
High blood levels of omega-3 have been found to result in less inflammation linked with heart disease and arthritis.
3. Regulates high cholesterol levels
Research on Inuit Eskimos, who get high amounts of omega-3 fatty
acids from regularly eating fatty fish, have shown to have increased
good cholesterol and reduced triglyceride levels (fats in the blood).
4. Lowers risk of blood clot
It has shown its anticoagulant properties by altering the ability of platelets in the blood to clot.
5. Beneficial for diabetes
Research studies reveals omega-3 fatty acids have shown to lower triglycerides and apoproteins, and no adverse effect on glycemic control.

6. Combats depression
It may be beneficial for people with mild
depression. It enhances the effectiveness of medication as it affects
the brain in a different way than antidepressants, so adding them to
antidepressant medication is like “attacking the illness from a
different front,” according to David Mischoulon, MD, a professor of psychiatry at Harvard Medical School.
7. Lowers blood pressure levels
Research has supported the blood pressure lowering effects of
omega-3’s, believed to be due to its anti-inflammatory and
anti-coagulant factors.
8. Improves brain function
According to Dr Alex Richardson, a senior
research fellow in physiology at Mansfield College, University of
Oxford and Madeleine Portwood,
that omega-3’s can improve brain memory and performance by improving
blood flow. In a clinical study, it has been found to be beneficial to
boys with learning and behavioral problems such as temper tantrums and
sleep disturbances.
9. Decrease risk of obesity
Omega-3’s is associated in normal kidney function so that they will
process fluid wastes better and thus, let people lose weight faster.
10. Menstrual Pain
Studies on women revealed that those who took fish oil supplements reported less menstrual pain. The two compounds eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are believed to decrease levels of prostaglandins. High levels of prostaglandins in women during menstruation results in increased uterine contractions and muscular spasm.
Is it beneficial for cancer?
Although there are many reports about omega-3’s being beneficial for
cancer, a review study published in 2006 by the Journal of the American
Medical Association reported that an analysis on numerous studies did
not find evidence of a significant link between dietary intake of
omega-3 fatty acids and the incidence of several major types of cancer.
Depression, fatigue, dry and itchy skin, brittle hair and nails and
joint pain are some of the possible symptoms of a need for more omega-3
fatty acids in the body. Too much can increase the risk of bleeding and
hemorrhagic stroke. It is best for people who bruise easily, have a
bleeding disorder, or are taking blood thinners to ask a doctor before
taking any supplements.
There is currently no established RDA for omega-3 fatty acids.
