Researchers from the University Regensburg in Germany after studying 2 dozen people using brain scans say yes it can. Half were asked to learn how to juggle and the others were given no specific instruction. After 3 months the brain of the jugglers had grown by 3 to 4 percent in the areas that process visual and motor information. The more skilled they became in juggling, the greater the brain growth. No change occurred in the non-juggling group.
In a recent report in the American Chemical Society's Journal of Agriculture and Food Chemistry, scientists note that two small servings of purple potatoes a day reduce blood pressure by about 4 percent without causing weight gain.
