Selecting a Mediterranean diet, which is a diet high in fish, olive oil, whole grains and vegetables helps to lower your risk of cognitive impairment according to a recent post-hoc data analyses.
Researchers examined data from the Age-Related Eye Disease Studies and found that study participants that had the highest fish intake had the slowest rate of cognitive decline. Cognitive function tests were performed on AREDS participants at 5 years and AREDS2 participants were tested at baseline, 2, 4 and 10 years later.
Not only did higher fish consumption offer higher cognitive function, but diets rich in vegetables and whole grains also demonstrated a slower rate of cognitive decline over the course of 5 to 10 years.
