Red raspberry research abounds at 2016 Experimental Biology conference
SAN DIEGO, CA – April 4, 2016 – A flurry of new research on red raspberries is set to be presented this week at the 2016 Experimental Biology conference in San Diego. Initial findings from six animal model studies reveal the potential effects of red raspberry consumption on cardiovascular disease risk reduction, maintaining normal blood glucose levels and liver function as well as potential anti-inflammatory effects related to bone health.
Recently, the January issue of Advances in Nutrition published a comprehensive review of the available scientific literature on the potential role of red raspberries in helping to reduce the risk of metabolically-based chronic diseases, including cardiovascular disease, diabetes mellitus, obesity, and Alzheimer’s disease: all of which share critical metabolic, oxidative and inflammatory links.
“The new research being presented at Experimental Biology contributes to the growing body of nutrition research around the potential role of red raspberries in helping to reduce the risk factors associated with metabolically-based chronic diseases,” said Tom Krugman, Executive Director of the National Processed Raspberry Council. “While further research in humans is needed, these animal studies provide important insights that will drive future research.”
Red raspberries contribute a number of valuable essential nutrients, including providing an excellent source of vitamin C and nine grams of fiber per cup. They are also among the few plant foods that provide a source of ellagitannins and anthocyanins in the same package. While in vitro and animal studies suggests that these phytochemicals may help to reduce risk for some chronic diseases, additional research is needed to test similar hypotheses and possible effects in human metabolism.
Animal and in vitro (cell) research on red raspberries being presented at Experimental Biology includes:

Inflammation and Bone Health
Dr. Amber Thomas, of the Department of Nutrition and Food Sciences at Texas Woman’s University and colleagues, using mouse macrophage cells, studied the anti-inflammatory effect of polyphenols in red raspberries in the production of osteoclasts, the cells associated with the breakdown of bone.

About National Processed Raspberry Council
Created in 2013, the National Processed Raspberry Council (NPRC) represents the processed raspberry industry and is supported by assessments from both domestic producers and importers. NPRC’s mission is to conduct nutrition research and promote the health benefits of processed raspberries. The NPRC is responsible for marketing processed raspberries in the U.S. and is committed to promoting the growth of the entire industry. Processed raspberries are frozen at the peak of ripeness to lock in flavor and nutrition.
