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. While some investigations have been conducted on humans, most of the group sizes were small, and the studies underfunded.
