When it comes to which type of chocolate is the healthiest, the answer is simple: it's dark chocolate by a landslide. Since dark varieties contain super-high cocoa contents (usually 70 to 80 percent, but many up to 100!), they contain more flavanols than milk chocolate.
Dark chocolate with a high percentage of cocoa (70% or more) is considered the healthiest type of chocolate, as it contains more antioxidants and less sugar than milk or white chocolate. As for chocolate manufacturers in the USA, some popular options include Ghirardelli, Lindt, and Theo Chocolate. However, it's always a good idea to check the ingredients and nutrition information to make sure you're choosing a high-quality and healthy option.
