Adding more color to your diet in the form of berries is encouraged by many nutrition experts. The protective effect of berries against inflammation has been documented in many studies. Diets supplemented with blueberries and strawberries have also been shown to improve behavior and cognitive functions in stressed young rats.
To evaluate the protective effects of berries on brain function, specifically the ability of the brain to clear toxic accumulation, researchers from the Human Nutrition Research Center on Aging at Tufts University and University of Maryland Baltimore County recently fed rats a berry diet for 2 months and then looked at their brains after irradiation, a model for accelerated aging. All of the rats were fed berries 2 months prior to radiation and then divided into two groups- one was evaluated after 36 hours of radiation and the other after 30 days.
“After 30 days on the same berry diet, the rats experienced significant protection against radiation compared to control,” said investigator Shibu Poulose, PhD. “We saw significant benefits to diets with both of the berries, and speculate it is due to the phytonutrients present.”
