While we tend to think of only the heart with cardiovascular health and disease, blood vessels play a very important role in maintaining cardiovascula...

Ramon Boudreaux, M.S.A common misconception is that the skeleton is a relatively fixed structure that undergoes few changes during adulthood. In actuality, bones are an extremely active tissue that continuously rebuild themselves throughout an individual’s lifetime (referred to as turnover).

In fact, the entire skeleton is completely...

Benjamin A. Tipton, M.S., SCCCCocoa and its derivative chocolate have been used for thousands of years by the cultures of Central America. Cocoa was such a fixture in the Aztec society that they used the beans as currency. Primarily, cocoa was brewed into a bitter drink until the beans were exported to Europe by the Spaniards. Europeans sweetened chocolate and later made it into bars during the industrial revolution. Today, dark chocolate, defined as having 60% cocoa content or greater, has rece...
