A study published in The Journal of Nutrition has found blueberry powder consumption reduces the size of breast tumors significantly in mice, website Nutraingredients.com reported.

Scientists from the Beckman Research Institute of the City of Hope in California, found animals that were fed blueberry powder in their diets had tumors that were between 65% and 70% smaller than the control population.

"Importantly, the dosage used in these studies was nontoxic and may be considered physiologic, because the human equivalent dose of the 5% BB diet (based on body surface area) is 300 g (10.6 oz.) of fresh blueberries (about 2 cups per day)," the researchers wrote in the journal.

"Future clinical trials using whole blueberry powder are planned that will aid in the determination of a suitable human dose. It is our hope that the knowledge gained from this study may aid in the design of future dietary strategies for the prevention of [triple negative breast cancer]."
