Omega-3 essential fatty acids (EFAs) found in deepwater fish, fish oil and vegetable oils such as flaxseed, walnut and canola, have been shown to nourish skin, hair and nails, reduce blood pressure and keep cholesterol and triglyceride levels in check. As a result of omega-3 EFA health benefits, the FDA in 2004 allowed for qualified health claims on products containing the nutrient.
The impact of this "healthy fat" on mortality rates is imminent. It's been found to reduce plaque build up on arterial walls and protect against cardiovascular disorders. It's also being looked at closely for its potential in reducing painful inflammation of the joints.
Prior to purchasing an omega-3 supplement, make sure levels of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) - compounds responsible for the nutrient's health benefits - are highly concentrated. Chances are you'll end up purchasing a fish oil supplement, the grade of which is indicated by the products freshness and purity, its distillation process and the absence of PCBs and heavy metals.
