Dark chocolate contains cocoa solids, cocoa butter, and usually minimal milk. Cocoa solids include a variety of compounds and small amounts of naturally occurring caffeine and theobromine. Products vary by cacao percentage, sweetness, and additions such as nuts or spices.
Portion size, timing, and individual taste drive how people incorporate dark chocolate into their day. Some prefer small servings earlier in the day, while others enjoy it as an occasional treat. Label reading helps compare cacao content and added sugars.
