Update on Omega-3s and Cognition

Published |1 comment

We’ve added the following to Omega-3s Part 2—Research:

A cross-sectional study on women 65 years and older found no difference in cognition between the those in the upper one-third compared to those in the lowest one-third of EPA-plus-DHA percentage of fatty acids in red blood cells (1). However, the lowest one-third had an average EPA plus DHA percentage of 3.8 which is quite a bit higher than average vegan percentages tend to be, so it’s not clear if this finding would apply to vegans.
