A few studies have been done which suggest that dark chocolate may be better than milk chocolate because it has a higher cocoa content. The cocoa is the ingredient that is known for its rich source of flavonoids (an antioxidant that clears out bad cells in the body) also found in some colorful vegetables, teas, and red wine.
Even though dark chocolate may contain ingredients that are beneficial to health, you should not necessarily eat more chocolate products. Chocolate is high in fat, sugar and calories. Moderation is always the key - having a piece of chocolate once in a while is not going to harm your health. Avoid replacing healthy foods with chocolate but when choosing chocolate for this Valentine’s Day, go for the dark chocolate for its higher flavonoid content.
