New animal research suggests that fat-laden meal plans can take a toll on the brain by effectively starving it of its energy supply. The story was published in the March issue of Neurobiology of Learning and Memory and was reported by ReutersHealth. Fatty diets have well-known health consequences, such as obesity and heart disease. In experiments with rats, investigators found that putting the animals on high-fat diets slowed their ability to learn new tasks. Compared with rats eating a standard diet, the fat-munching animals performed more poorly on tests of learning and memory, according to a report The study's authors, Drs. Carol Greenwood and Gordon Winocur, believe high-fat diets may hinder brain function by promoting resistance to insulin, a hormone that plays a key role in controlling blood sugar "At this point, we believe the link (between high-fat diets and impaired brain function) is diabetes," said Greenwood, of the University of Toronto in Canada. This theory, she told Reuters Health, supports work suggesting that diabetics often suffer a decline in certain mental functions such as long-term memory.
