Although all fats were once seen as bad, research today indicates that certain fats, especially omega-3 fatty acids, are healthy fats that can perform numerous functions in the body that enhance overall health. Omega-3 fatty acids are polyunsaturated fats composed of eicosapentaenoic acid and docosahexaenoic acid. Whether receiving it from food sources or supplements, omega-3 fatty acids help fight against some of America's biggest health problems.
Improves Alzheimer's Disease Symptoms
Yvonne Freund-Levi led a team of researchers who examined the effects of omega-3 fatty acid supplementation on patients with mild to moderate cases of Alzheimer's disease, according to findings reported in the "International Journal of Geriatric Psychiatry." Participants received omega-3 fatty acids or a placebo. Scientists found that the omega-3 fatty acid group experienced improvement in depression and agitation symptoms normally associated with Alzheimer's disease. Although these results are promising, further research is needed, according to researchers.
Improves Heart Health
Omega-3 fatty acids might improve heart health, according to the Science Daily website. Omega-3 fatty acids have been shown to be effective in reducing triglycerides, decreasing blood pressure and reducing blood clotting. Furthermore, it also reduces the risk of heart rhythms, which decreases the risk of cardiac arrest. For those with heart disease, taking omega-3 supplements such as fish oil are effective for boosting heart health while those without heart disease should stick to fatty fish such as tuna and salmon.
Reduces Gum Disease Risk
Dr. Asghar Naqvi and colleagues studied the relationship between omega-3 fatty acid intake and gum disease, according to research published in the "Journal of the American Dietetic Association." In reviewing data from subjects who participated in the National Health and Nutrition Examination Survey between 1999 and 2004, scientists found that participants consuming the most DHA and EPA significantly reduced their risk of gum disease compared to those with the lowest intakes.
