Learning, Memory Improve With Increased Levels Of Omega-3 Fatty Acids

May 15, 2012: 12:00 AM EST
A U.S. study confirms that eating a high-fructose diet for a long period of time harms the brain’s ability to learn and remember information, but increasing the amount of omega-3 fatty acids in  the diet counteracts the adverse effects. The study in rats showed that fructose – from, for example cane sugar (sucrose) and high fructose corn syrup – impedes the synapses’ ability to transmit signals between brain cells. But the problem can be overcome if the brain has access to omega-3 fatty acids such as DHA, which improves synaptic functions.
