Chocolate contains over 300 chemicals, and has been the subject of a number of studies by universities and other scientific organizations. Yet in chocolate there are vitamins essential for our body's proper functioning. The same chocolate contains calcium, potassium, iron, vitamin A, vitamin B1, vitamin C, vitamin D, and vitamin E. Chocolate contains flavonoids, that are great for your heart. The definition that American Heritage Dictionary gives for flavonoid is any of a large group of water-soluble plant pigments, including the anthocyanins that are beneficial to health. Flavonoids act as antioxidants to our bodies. Flavonoids repair damage and protect from environmental toxins. Flavonoids are found in many foods and beverages. Flavonoids are found in cranberries, apples, peanuts, red wine, tea, onions, and most importantly, chocolate just to name a few.
