Cacao is the raw form of dark chocolate, and it’s what everyone is talking about when studies show that chocolate is good for you. Cacao nibs are the raw, dehydrated and crushed cocoa bean, prior to adding sugar and milk to make it delicious. Truth be told, raw cacao is a little bit bitter and almost disappointingly tasteless. But it truly is so good for you: it’s loaded with heart healthy antioxidants that prevent disease and lower cholesterol. A compound called theobromine gives caffeination without the jitters. And cacao is also a fantastic source of magnesium which seems to help with PMS symptoms. So yes, ladies, you’re welcome and encouraged to reach for raw chocolate around that time of the month.
