Omega-3s could help reduce risk of brain diseases
The omega-3 DHA is specifically associated with improved cognition and behavior.
05/10/05 Long-chain omega-3 polyunsaturated fatty acids (PUFAs) appear to reduce the risk or progression of Alzheimer's and Parkinson's diseases, according to recent research summarized in the September 2005 PUFA Newsletter. The omega-3 DHA is specifically associated with improved cognition and behavior.
A series of studies with biotech mice with Alzheimer's disease indicated that deficiency in the omega-3 DHA hastened the development and severity of Alzheimer's disease in these mice. Another study added to previous evidence that higher intakes of PUFAs reduce one's risk of developing Parkinsonism.
A review of scientific literature to date described in the PUFA Newsletter concludes that DHA is needed for brain development. A report on infant brain development and maternal DHA supplementation during lactation underscores this benefit. Other new research reports that PUFAs from both the omega-3 and omega-6 families are linked to improved learning and behavior in children with developmental coordination disorder.
Reduction of fatal arrhythmias is considered a primary effect of long- chain omega-3s in patients who have had a heart attack. However, results from a U.S. study of patients with implanted defibrillators who fared worse after consuming fish oil created doubts about the cardiovascular benefits of these fatty acids. In contrast, a study from Denmark reported lower risk of heart attacks in patients with defibrillators whose omega-3 levels were high.
Other scientific findings discussed in the newsletter further the prospect of bioengineering oilseed plants to produce DHA, which is naturally found in algae and consumed in human diets via fatty fish. This breakthrough research gives the public hope for greater access to beneficial PUFAs in the food supply.
