Fish oil may stall effects of junk food on brain
Date:5/14/2013

fter eating, and which normally protect neurons and stimulate their growth, are prevented from passing into the brain by increased circulation of inflammatory molecules and a type of fat called triglycerides.

Molecules that stimulate nerve growth are also reduced, but it appears, in studies with animal models, that omega-3s restore normal function by interfering with the production of these inflammatory molecules, suppressing triglycerides, and returning these nerve growth factors to normal.

Dr Pickavance added: "Fish oils don't appear to have a direct impact on weight loss, but they may take the brakes off the detrimental effects of some of the processes triggered in the brain by high-fat diets. They seem to mimic the effects of calorie restrictive diets and including more oily fish or fish oil supplements in our diets could certainly be a positive step forward for those wanting to improve their general health."

The research is published in the British Journal of Nutrition. Dr Pickavance will also be discussing the effects of high-fat diets on meal patterns and the impacts of high-saturated fats on muscle composition at the 20th European Congress on Obesity at the Liverpool Arena and Convention Centre later this month.

Dr Pickavance will exhibit her work on obesity at Liverpool World Museum for members of the public on the 8 June, as part of the University's Institute of Ageing and Chronic Disease 'Meet the Scientist' event.
