American scientists suspect that the excessive consumption of sugar reduces mental capacity. Sweet have difficulty learning and the acquisition of information.
For their study, the researchers of the University of California at Los Angeles divided rats into two groups. And those, and others, within six weeks fed a solution of corn syrup, high fructose . In this rodent in the first group are regularly fed unsaturated fatty acids which stimulate brain activity. The second group of rats, this "dessert" not received.
Note that before you start the experiment, the scientists repeatedly placed rats in a maze, forcing them to look for a way to learn. There also they were placed at the end of the study, which lasted six weeks.
It was found that rats treated with the additive in the form of fatty acids, began to move slowly, could not think clearly and remember how to get out of the maze . However, the rats of the second group developed signs of resistance to insulin - the hormone that controls the level of glucose in the blood, and is responsible for the functioning of brain cells.
"Our research indicates that excessive fructose consumption harms the brain as well as the body," - said the professor of neurosurgery Fernando Gomez-Pinilla. According to him, the high level of glucose in the blood interferes with the brain to absorb new information.
"These findings suggest that what we eat affects how we think , "- quoted by ITAR-TASS to scientists.
