The link between chocolate and acne could be a myth. The studies on the subject are not many, still their results point to little by way of conclusive evidence that chocolate does indeed lead to pesky spots. The occurrence of acne in combination with the consumption of chocolate could be triggered by dairy intolerance. It is thus not the cocoa in itself that might give you that umpleasant side effect.

Moreover, according to Rhiannon Lambert, a British nutritionist, the nutritional value - or lack of - in your chocolate fix depends on the composition of the chocolate and sugar content. Broadly speaking, dark chocolate contains less sugar, so it's less likely to lead to fatty weight gain.
