"...Analyses revealed that omega-3 fatty acids--in particular DHA (docosahexaenoic acid), a specific type of omega-3--had replaced the omega-6 fatty acids already present in the brains of the mice that had been given omega-3 supplementation..."This demonstrates both the importance of diet on the brain's fatty acid composition and the brain's natural inclination for omega-3 fatty acids," observes Calon. Since concentrations of other types of omega-3's had remained similar in both groups of mice, researchers suggest that the protective effect against Parkinson's comes essentially from DHA...Another conclusion to be drawn from this finding is that a brain containing a lot of omega-6 fatty acids may be a fertile ground for Parkinson's disease. These fatty acids, abundant in foods rich in either vegetable oil or animal fat, are already under suspicion for their role in the body's inflammatory response, cardiac disease, arthritis, and Alzheimer's. In a balanced diet, the ratio between omega-6 and omega-3 fatty acids should be 4 to 1. However, the average Western diet contains 10 to 20 times more omega-6's than omega-3's..."In North America, the average intake of DHA is between 60 to 80 mg a day, while experts recommend a daily minimum of 250 mg,"..."
