Omega-3 fatty acids protect against Parkinson's, study says
Date:11/26/2007

ations of other types of omega-3s had remained similar in both groups of mice, researchers suggest that the protective effect against Parkinsons 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 Parkinsons disease. These fatty acids, abundant in foods rich in either vegetable oil or animal fat, are already under suspicion for their role in the bodys inflammatory response, cardiac disease, arthritis, and Alzheimers. 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-6s than omega-3s.

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, explains Calon. Our results suggest that this DHA deficiency is a risk factor for developing Parkinsons disease, and that we would benefit from evaluating omega-3s potential for preventing and treating this disease in humans, concludes the researcher.
