If you buy quality dark chocolate with a high cocoa content, then it’s quite nutritious.
It contains a decent amount of soluble fiber and is loaded with minerals.
A 100-gram bar of dark chocolate with 70–85% cocoa contains (1):
- 11 grams of fiber
- 67% of the DV for iron
- 58% of the DV for magnesium
- 89% of the DV for copper
- 98% of the DV for manganese
In addition, it has plenty of potassium, phosphorus, zinc, and selenium.
Of course, 100 grams (3.5 ounces) is a fairly large amount and not something you should be consuming daily. These nutrients also come with 600 calories and moderate amounts of sugar.
For this reason, dark chocolate is best consumed in moderation.
