Eating Strawberries May Prevent Breast Cancer, Mouse Study Suggests
Strawberry extract can inhibit the growth and spread of highly aggressive breast cancer, various European studies in mice and lab-grown cells have shown. While the findings suggest that strawberry consumption could prevent breast cancer in humans, researchers say clinical and epidemiological studies are needed to verify this. The study, "Polyphenol-rich strawberry extract (PRSE) shows in vitro and in vivo biological activity against invasive breast cancer cells," appeared in Scientific Reports. Past research has shown that eating 10 to 15 strawberries a day offers antioxidant and anti-inflammatory benefits and reduces cholesterol levels in the blood. Now, European and Latin American researchers have found that strawberries have strong anti-cancer properties against a highly tumorigenic and invasive breast cancer cell line. "We have shown for the first time that strawberry extract, rich in phenolic compounds, inhibits the proliferation of breast cancer cells in in vitro and in vivo models," Maurizio Battino, co-author of the paper, said in a press release. Battino is a principal investigator at Italy's Marche Polytechnic University as well as the European University of the Atlantic in Santander, Spain. The team treated the cells in culture with different concentrations — between 0.5 and 5 mg/ml — of the Alba variety of strawberry, for periods of 24, 48 and 72 hours. It found that the higher the dose of strawberry extract and the longer th
