1 Omega-3s
There's more evidence that consuming omega-3 fatty acids is good for your heart.
Researchers in Finland followed 285 men and 130 women with coronary, heart disease. The volunteers' average age was 61.
As the study progressed, 36 participants died, 21 suffered heart attacks and 12 had strokes. But among all participants, those with the highest concentration of docosahexaenoic acid--an omega-3--showed a 69 percent lower risk of death than people with the lowest levels.
Exactly how omega-3 fatty acids work is unclear. They may lower triglycerides in the blood, or they may make blood platelets less likely to clot.
Omega-3 sources include fatty fish, flaxseeds and flaxseed oil, olive oil and dietary supplements.
The study was published in the July 2003 issue of The American Journal of Clinical Nutrition.
