Fatty Foods Affect Memory and Exercise By TARA PARKER-POPE
High-fat foods may have detrimental effects on muscle power and the brain.
Eating 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.
It’s already known that long-term consumption of a high-fat diet is associated with weight gain, heart disease and declines in cognitive function. But the new research shows how indulging in fatty foods over the course of a few days can affect the brain and body long before the extra pounds show up.
To determine the effect of a fatty diet on memory and muscle performance, researchers studied 32 rats that were fed low-fat rat chow and trained for two months to complete a challenging maze. The maze included eight different paths that ended with a treat of sweetened condensed milk. The goal was for the rat to find each treat without doubling back into a corridor where it had already been. The maze was wiped down with alcohol, so the rat had to rely on memory rather than sense of smell.
All of the rats studied had mastered the maze, finding at least six or seven of the eight treats before making a mistake. Some rats even found all eight on the first try.
Then half the rats were switched to high-fat rat chow (comprised of 55 percent fat), while the remaining rats stayed on their regular chow (which had 7.5 percent fat). After four days, the rats eating the fatty chow began to falter on the maze test — all of them did worse than when they were on their regular chow. On average, the rats on the fatty diet found only five treats before making a mistake. The rats who stayed with their regular food continued the same high level of performance on the maze, finding six or more treats before making a mistake.
