Fish oil could slow brain effects of high-fat diet
Junk food is bad for your waistline, but it's also bad for the brain. Research indicates that eating too many refined sugars and saturated fats can disrupt the brain's ability to control the amount of food the body should take in. However, researchers from the University of Liverpool (U.K.) have found that fish oils could minimize this effect.
Through the study of 185 research papers, the University of Liverpool team attempted to learn what role omega-3 fish oils played in weight loss. The researchers theorized that a high-fat diet can disrupt neurogenesis, the process by which the brain generates new nerve cells. But the research did not show a direct link between junk food and this process.
What the researchers did find, though, was that omega-3s play a significant role in stalling refined sugars' and saturated fats' ability to inhibit the brain's control on the body's intake of food. Junk food disrupts the mental processing which keeps the body from taking in too much food, and the research indicates that fish oils may interfere with this effect. Junk food also reduces molecules that stimulate nerve growth, where omega-3s were found to restore normal function in these areas.
While fish oils may not have a direct impact on weight loss, they could help counter some of the detrimental effects triggered in the brain by eating a high-fat diet.
