Fat
Chocolate also contains relatively high amounts of fat. Dark chocolate contains 12 grams of fat per ounce, including 7 grams of unhealthy saturated fat. This amount is 7 percent of the daily value for fat and 35 percent of the DV for saturated fat if you consume 2,000 calories per day. Milk chocolate contains 8.5 grams of fat per ounce, including 5.3 grams of saturated fat. Fat contains more calories per gram than protein or carbohydrates, so if you consume too much fat you may have difficulty staying within your daily calorie limit. Moreover, excessive saturated fat consumption increases your risk for Type 2 diabetes and heart disease.
