In a report published Wednesday in the journal PLOS One , researchers say that eating any amount of trans fats, such as those found in processed baked goods and cookies and some margarines, can wreak havoc on your memory. Beatrice Golomb, professor of medicine at University of California San Diego, and her colleagues analyzed diet information on healthy men and women who were part of a study on cholesterol-lowering drugs.
The participants answered detailed information about what they ate, including how their food was prepared, and the scientists then calculated the amount of trans fats the volunteers consumed based on their responses. Each participant also took part in a word recall test to measure their memory; they were presented with a series of word cards; the first time they saw a set of cards, then they saw another set in which only 22 words remained the same, and were asked to identify which were new and which were repeats.
And, this effect seemed to be worse among younger volunteers than older ones. The presence of the fats can lead to a higher level of unstable oxygen molecules which can in turn destabilize DNA, proteins and other fats, prompting affected cells to die off. The fact that the younger participants seemed to show worse effects than older ones may simply reflect the fact that older people are already experiencing declines in memory due to other, cumulative effects of brain injury, from poor sleep to a lifetime of traumatic injuries.
Essentially, for every gram per day of dietary trans fat the participants ate, the volunteers were able to accurately recall 0. The FDA currently allows companies whose products contain 0.
