So how can one reap these delicious health and beauty benefits if one is not on the M&Ms pill? Well, finding dark chocolate that has at least 70 percent cocoa is a good start. Most chocolate bars will have that information on the front of the label if it is made with at least 70 percent cocoa. If this is not on the label, check the back label. If the first ingredient is milk or sugar, it most likely does not have the amount of cocoa needed to reap the health and beauty benefits.
