Diet is a powerful force as we say time and again. Most of the studies revolve around the physical aspects: inflammation, disease risk, body composition, blood markers, etc. But there’s the promise a good diet can offer other elements of health, including cognitive performance. With climbing rates of dementia and Alzheimer’s, these correlations are nothing to shake a stick at.
In that vein, this recent study caught our eye. Researchers from the University of Muenster in Germany followed subjects who had been grouped into three practices: a caloric restriction group (30% cut in daily intake), a group that increased their consumption of essential fatty acids (20% increase), and a control group. After three months, all subjects retook tests focused on memory activities. The group that cut its calories showed a “significant increase” in scores related to verbal memory. The apparent cognitive improvement could be correlated, the researchers say, with “decreases in fasting plasma levels of insulin and high sensitive C-reactive protein.” No noteworthy changes were seen in the other subjects.
