Eating fish may prevent Parkinson's disease
Eating two servings of fish a week could protect you from developing Parkinson's disease, according to Canadian research.
A study by Laval University in Canada has shown that mice fed on a diet high in a specific type of omega-3 fatty acid did not develop Parkinson's, even when given a toxic compound that can cause symptoms similar to the disease.
Because the fatty acid – known as DHA – is found in oily fish, Frederic Calon, co-author of the study, recommended people eat two servings of fish a week, although he pointed out that researchers are, as yet, unable to say how much DHA humans should consume.
One
serving of fish can contain two grams of DHA. Some studies have
recommended a diet of 500 grams a day in omega-3s.
"What we expect is that (DHA) can have a similar effect in humans and, hopefully, could prevent the disease or slow down its development at the beginning," Calon said.
Parkinson's is a degenerative disorder of the central nervous system that causes trembling and stiffness of the limbs. It mainly affects people in their 60s and 70s.
However, Calon urged consumers to be aware of some food products that claim to be rich in omega-3s, as some don't contain the essential compound DHA and, even if they do, they might not contain enough.
The study was funded by the Parkinson Society of Canada.
