Information reported in the journal PLoS Medicine lists lack of proper Omega-3 fat in the diet as one of the ten leading preventablecauses of death. The journal estimates that nearly 100,000 die each year due to Omega-3 fat deficiency while many more suffer debilitating heart attacks, strokes and cognitive damage as a result. Another study published in the Nutrition Journal provides evidence that men with the highest levels of the Omega-3 fat, DHA ran a 34% lower risk of developing heart disease. Older adults with the highest total Omega-3 concentrations ran a 70% lower risk of a fatal heart attack.
