Dark black chocolate (also known as black chocolate, plain chocolate, or sour chocolate) is a form of chocolate containing cocoa solids, cocoa butter and sugar, without the milk found in milk chocolate.[1] Government and industry standards of what products may be labeled "dark chocolate" vary by country and market.[1]

Although dark chocolate has a reputation as a healthier alternative to other types of chocolate, such as milk chocolate,[2] high-quality evidence for significant health benefits, such as on blood pressure, has not been shown.[3][4]

Research[edit]

As of 2018, high-quality clinical trials have not been conducted to evaluate the effects of cocoa compounds on physiological outcomes, such as blood pressure for which only small (1-2 mmHg) changes resulted from short-term consumption of chocolate up to 105 grams and 670 milligrams of flavonols per day.[3][4] In dark chocolate, flavanols include monomers, epicatechins, and catechins.[3]

Nutritional content[edit]

Dark chocolate is 1% water, 46% carbohydrates, 43% fat, and 8% protein (table). In a 100 grams (3.5 oz) reference amount, dark chocolate supplies several dietary minerals in significant content, such as iron at 92% of the Daily Value (DV) and vitamin B6 at 29% DV (table). Dark chocolate contains 70-100% cocoa solids (nutrition table).
