FACTS
In the 1970s, scientists noticed an interesting phenomenon: although Eskimos consumed large amounts of fat daily, they had an exceptionally low rate of heart disease and cancer. But unlike others who also ate lots of fat – notably from meat and dairy products – the predominant fat in the Eskimo diet was in the form of omega-3 fatty acids. Omega-3 is found primarily in marine plant life called phytoplankton, which is eaten by fatty fish, a mainstay of the Eskimo diet. Omega-3 contains two polyunsaturated fats: docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
On land, omega-3 is found in some plant food including flaxseed (linseed), walnut, soybean and canola, and their oils. These contain alpha-linolenic acid (LNA), which is converted to omega-3 fatty acid in the body.
Clinical trials have shown that omega-3 fatty acid supplementation can reduce the risk of heart disease.
CLAIMED BENEFITS
- Reduces risk of heart attacks
- Reduces triglycerides
- Mildly reduces blood pressure
- Decreases risk of arrhythmias, which can lead to sudden death
- Prevents clots (anti-thrombotic effects)
- Stroke
RIGHT AMOUNT
A dietary approach to increase omega-3 fatty acid is preferable. However supplements may be useful for those with heart disease or those who don’t have enough omega-3 in their diet (1-2 capsules of 1000mg daily with meals).
