It is true that dark chocolate is the best because it has the most cocoa in it and provides all the wonderful antioxidants that chocolate can provide. I know you are thinking I can't give up my milk chocolate or go to the dark side, but you can do both! Chocolate has different percentages telling you how dark it is so if you are not a dark fan go with a 30-40% but above 55% is really the best. Also I learned that I was just not eating my chocolate correctly. You need to savor it, smell it, and slowly let it melt in your mouth and really indulge in that piece of chocolate. Also if you need help going to the dark side start milky and gradually up the percentages. I think the highest I've gone is 88% and have really enjoyed it without the dirt taste.
Some fun facts: the louder the snap of a chocolate bar the higher quality it is. There is only 5-30 mg of caffeine in chocolate which is less than a cup of decaf. There are endless benefits from eating chocolate because of all the antioxidants, good fats, vitamins (lots of magnesium) and increased serotonin when one enjoys some chocolate!
