Nonetheless, it must be said that this particular study is not the first one that targets trans fats and their effect on human memory – there have been numerous similar studies conducted in the past, but this is the first one that actually targets a group of younger adult men. For instance, there was yet another similar study that was conducted in the United Kingdom on a small number of young women, and there was yet another one conducted two years ago on older women, the latter has also revealed that women who had high-fat diets (not just trans fats, but all sorts of fats) faced significantly more memory challenged than those who did not.
In spite of the fact that the results of the study seem to show a definitive link between the increased consumption of trans fats and memory loss, scientists are still reluctant to claim that there is a direct connection between the two, given the fact that this kind of study cannot show a certain cause and effect. Nonetheless, it is still known that consuming large amounts of fats, and trans fats in particular, can lead to what is known as oxidative stress (a type of cell damage) which, in turn, can cause memory loss, amongst other severe health effects.
The oxidative stress theory does make sense and it is also backed up by Dr. Olivia Okereke, an assistant professor of psychiatry within the Harvard Medical School, who has thoroughly studied the effects of oxidative stress on the older female population. Even so, nobody can tell for sure whether the increased consumption of trans fat alone is to blame for the memory loss, or if there are various other factors that also take their toll on one’s memory. The American Heart Association also advises Americans to limit their daily intake to a maximum of two grams a day, or even less if that is possible, and this includes limiting the amount of processed foods people consume as well.
