Beware saturated fats: The butter brain myth

26 Jun



The Internet and other media have been awash with claims that saturated fats are good for you. One new fad is the “butter brain,” the argument that eating butter will improve cognition.

I believe that this advice is dangerous. It is not impossible that consumption of a high lipid food might improve short term performance on a cognitive test, but long term consumption of these products have been linked to cardiovascular disease, a major contributor to dementia.

This short article from The Pacific Standard puts things in perspective.

A paper titled ” Dietary fat types and 4-year cognitive change in community-dwelling older women” can be found here. From the paper’s conclusion:

“In this study of community-dwelling older women, higher saturated fat intake was associated with a poorer 4-year trajectory of global cognition and verbal memory.”
