Semi-sweet chocolate is often referred to as bittersweet or dark chocolate. It’s mostly cocoa powder and cocoa butter with some sugar. Usually when people say “semi-sweet” or “bittersweet” chocolate, they’re referring to the chocolate bars made for baking. These are absolutely Paleo-friendly, and even come with proven health benefits!
The Fat Profile
The fat in dark chocolate comes from cocoa butter, which is almost entirely saturated and monounsaturated fats, which we like. They are stable when exposed to heat and light and have actually been shown to improve cholesterol levels.
Chocolate and Anti-oxidants
Chocolate also comes loaded with flavanols, a type of polyphenol that is meant to protect the plant, but imparts all sorts of health benefits for humans when consumed. Bad for the plant. Good for us. Chief among these health benefits are reduced blood pressure, improved glucose tolerance, and reduced risk of heart disease.
