Question: how many carbs are in a piece of dark chocolate?
Answer: However, it's important to choose dark chocolate that contains a minimum of 70 percent cocoa solids, preferably more. One ounce (28 grams) of unsweetened chocolate (100 percent cocoa) has 3 grams of net carbs. The same amount of 70–85 percent dark chocolate contains up to 10 grams of net carbs (92, 93).
