Blueberries Linked to Improved Cognition
Results of a recent study published in the European Journal of Nutrition suggest the equivalent of one cup of fresh blueberries—24 grams of freeze-dried powder—daily can help improve cognitive function in older adults. The study—a randomized, double blind, placebo-controlled trial—was conducted at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University.
The study involved 13 healthy men and 24 healthy women between 60 and 75 years old. Study participants received freeze-dried blueberry powder daily or a placebo and were tested balance, gait, and cognition at the start of the study and then again after 45 days and 90 days.
More studies are needed. According to researchers, however, blueberries have a number of health benefits and adding them to the diet may be an overall positive nutrition and lifestyle strategy for older adults.
