Brain Stroke -Take Fish Oil To Avoid Acute Stroke
Brain Stroke. A new study on omega 3 came out by the Université Laval and was commented by Dr. Jonny Bowden blog where they found out that less sever stroke occurs when there is a diet high in omega 3 fats.
ScienceDaily (Aug. 26, 2011) — A diet rich in omega-3s reduces the severity of brain damage after a stroke, according to a study conducted by Université Laval researchers.
The team, co-directed by professors Jasna Kriz and Frédéric Calon, showed that the extent of brain damage following a stroke was reduced by 25% in mice that consumed DHA type omega-3s daily. Details of the study can be found on the website of the journal Stroke. Photo courtesy of alles-schlumpf
Brain Stroke – Less Inflammation With DHA (Omega 3)
Researchers observed that the effects of stroke were less severe in mice that had been fed a diet rich in DHA for three months than in mice fed a control diet. In mice from the DHA group, they saw a reduction in the concentrations of molecules that stimulate tissue inflammation and, conversely, a larger quantity of molecules that prevent the activation of cell death. “This is the first convincing demonstration of the powerful anti-inflammatory effect of DHA in the brain,” underscored Frédéric Calon of Université Laval’s Faculty of Pharmacy. This protective effect results from the substitution of molecules in the neuronal membrane: DHA partially replaces arachidonic acid, an omega-6 fatty acid known for its inflammatory properties. “The consumption of omega-3s creates an anti-inflammatory and neuroprotective environment in the brain that mitigates damage following a stroke,” summarized Jasna Kriz, of Université Laval’s Faculty of Medicine. “It prevents an acute inflammatory response that, if not controlled, is harmful to brain tissue.” Professor Calon believes that this anti-inflammatory effect is likely transferable to humans. “Since DHA is readily available, inexpensive, and reduces the risk of a number of health problems without causing significant side effects, the risk-benefit ratio tends to favor the regular consumption of fish or DHA,” he concluded.
