HealthDay News — Consumption of trans fats may negatively affect memory, according to research findings published in PLOS ONE.

To assess the relation of dietary trans fatty acid (dTFA) consumption to word-memory, Beatrice Alexandra Golomb, MD, PhD, of the University of California, San Diego School of Medicine, and colleagues evaluated dietary survey data from 645 healthy male patients. The patients were also given a memory test.

On average, men aged 45 years and younger recalled 86 words out of 104. But for each additional gram of trans fats consumed daily, their performance dropped by 0.76 words, the study revealed. Men whose daily diet contained about 16 grams of trans fats recalled 12 fewer words correctly. Men who consumed as much as 28 grams of trans fats daily recalled about 21 fewer words.

The FDA recently ruled that partially hydrogenated oils are no longer "generally recognized as safe," the designation that for decades has allowed companies to use the oils in a wide variety of food products. Companies have until June 18, 2018, to either reformulate their products and remove all partially hydrogenated oils, or petition the FDA to permit specific uses of the oils, the agency announced.
