Eating More Trans Fats Could Be Bad for Memory

A new study in PLOS ONE reports that greater consumption of dietary trans fatty acids (dTFA) is strongly linked to worsening memory in men aged ≤45, compared to men who consume no dTFA.

Lead author Beatrice A. Golomb, MD, PhD, of the University of California, San Diego School of Medicine, and colleagues reviewed data from 1,018 men and women who completed a dietary survey and memory test involving recall. Men aged ≤45 recalled an average of 86 words, but word recall dropped by 0.76 words per additional gram of dTFA consumed each day. The researchers estimate that for those with the highest dTFA intake levels observed in the study, this was linked to about 12 fewer recalled words per memory test. This association was not observed in older adults.

Recently, the Food and Drug Administration (FDA) announced that it will now require food manufacturers to remove partially hydrogenated oils (PHOs) from products within three years. PHOs are the primary source of artificial trans fat in processed foods. Studies have indicated that trans fatty acids can impact lipid profiles, metabolic function, insulin resistance, inflammation, and cardiac and general health.
