While not able to cure Alzheimer’s or Parkinson’s diseases, eating blueberries certainly has its benefits. Studies from the U.S. Department of Agriculture and Rutgers Blueberry and Cranberry Research Center suggests the fruit ranks very high in antioxidant capacity, can help ward off urinary tract infections, lowers the risk of blood clots, and reduces the risk of cardiovascular disease. Though positive research does exist regarding its success at lowering dementia-type illnesses, most of the research has only been conducted on rodents.
According to Mary Ellen Camire, associate professor of food science and human nutrition at the University of Maine, Orono, eating dried blueberries can relieve diarrhea. Apparently, certain compounds found in blueberries, like tannin, stop the proliferation of bacteria associated with diarrhea. It is important to remember, however, only dried blueberries can alleviate diarrhea; blueberries that are either fresh or frozen may actually compound the situation.
