BENEFITS OF DARK CHOCOLATE
VERY NUTRITIOUS
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:
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.
POWERFUL SOURCE OF ANTIOXIDANTS
Dark chocolate is loaded with organic compounds that are biologically active and function as antioxidants. These include polyphenols, flavanols and catechins, among others.
​
However, it’s worth mentioning that raw, unprocessed cocoa beans are among the highest-scoring foods that have been tested.
​
One study showed that cocoa and dark chocolate had more antioxidant activity, polyphenols, and flavanols than any other fruits tested, which included blueberries and acai berries.

COULD IMPROVE
BRAIN FUNCTION
Dark chocolate may also improve the function of your brain.
One study of healthy volunteers showed that eating high flavanol cocoa for 5 days improved blood flow to the brain.
Cocoa may also significantly improve cognitive function in older adults with mild cognitive impairment. It may improve verbal fluency and several risk factors for disease, as well.
Additionally, cocoa contains stimulant substances like caffeine and theobromine, which may be a key reason why it can improve brain function in the short term.
