Plasma Phospholipid Long-Chain ω-3 Fatty Acids and Total and Cause-Specific Mortality in Older Adults: A Cohort Study
Authors: D. Mozaffarian, et al. / Journal: Annals of Internal Medicine, April 2013Summary
This is a 30-year study that looked at 2692 adults and compare mortality rates between those with higher plasma levels of omega-3 PUFA biomarkers with those who are lower. The study found those with higher omega-3 PUFA levels had a lower mortality rate than those who have less omega-3 PUFA levels. On average, those with higher levels lived 2.22 more years after age 65 years than those in the lowest quintile.
Inverse relationship between long-chain n-3 fatty acids and risk of sudden cardiac death in patients starting hemodialysis
Authors: A. N Friedman, et al. / Journal: Kidney International, February 2013Summary
Experimental and clinical evidence suggests that long-chain n-3 fatty acids may protect against sudden cardiac death, the leading cause of mortality in hemodialysis patients. The study found significant inverse relationship was maintained even during the highest-risk first few months on hemodialysis. Thus, long-chain n-3 fatty acids are strongly and independently associated with a lower risk of sudden cardiac death in hemodialysis patients throughout the first year of hemodialysis.
Red blood cell omega-3 fatty acid levels and markers of accelerated brain aging
Authors: Z.S. Tan, et al. / Journal: Neurology, February 2012Summary
Researchers studied over 1,500 late middle aged adults without dementia to see how the levels of omega-3s in their blood are related to signs of future dementia. Adults with the lowest amount of the fish-based omega-3, DHA, in their blood had smaller brain volumes and poorer performance in tests of visual memory; abstract thinking; and planning, organization, and carrying out of tasks than adults with higher DHA levels.
