It is said that eating fish is good for the memory and the brain because the pesce it contains DHA, an Omega 3 fatty acid with beneficial properties for various fundamental functions of the organism.
Some researchers have indeed discovered a possible explanation and published their findings in the journal Applied Physiology, Nutrition and Metabolism. Investigators revealed that laboratory models fed a high-DHA diet have elevated levels of DHA in the section of memory in the brain known as the hippocampus, compared to animals fed a normal diet. "We wanted to understand how fish intake improves memory," said Dr. Sauve, medical researcher at the University of Alberta. "
Memory cells in the hippocampus have been found to communicate better with each other when DHA levels are high. This could explain why a fish-based diet improves memory ”. Research has also shown that DHA prevents the accumulation of a toxic molecule in the back of the eye, which causes blindness in old age. "
