Not only does chocolate have a rich history, it is also rich in health benefits. The cocoa plant is full of flavanols, naturally derived chemicals found in plants that support heart health by improving blood flow and lowering blood pressure. In a study on the Kuna Indians, an isolated group who lived on the Caribbean Coast of Panama, low blood pressure and high cocoa intake was linked. The Kunda consumed large amounts of the cocoa plant and had very few cases of hypertension. But when they moved into urban areas and began consuming less cocoa, their rates of high blood pressure increased.
