Image via WikipediaEating fatty food appears to take an almost immediate toll on both short-term memory and exercise performance, according to new research on rats and people.
Half of the rats had also been trained to run on a treadmill. After only a few days on the high-fat diet, the rats performed 30 percent worse on the treadmill. After five days of testing, the treadmill performance of the rats eating fatty foods had declined by half. The study results appear in The Faseb Journal, which is the journal of the Federation of American Societies for Experimental Biology.
It’s not clear why fatty foods would cause a short-term decline in cognitive function. One theory is that a high-fat diet can trigger insulin resistance, which means the body becomes less efficient at using the glucose, or blood sugar, so important to brain function.
