Overview

Why eat dark chocolate (60–69%)?

Dark chocolate in this range is a treat first, but a genuinely mineral-rich one, supplying copper, magnesium and iron alongside cocoa flavanols. It is also dense in calories, sugar and saturated fat, so it works best as a small square enjoyed slowly rather than an everyday health food.

Good to know: A 100 g bar carries 579 calories, 36.7 g sugar and 110% of the Daily Value for saturated fat, plus about 86 mg caffeine, so keep portions to a square or two, especially in the evening.

  1. Rich in copper

    One ounce delivers 0.35 mg of copper, about 39% of the Daily Value, a mineral needed for iron transport, connective tissue and energy production.

  2. Magnesium for muscles and nerves

    With 176 mg of magnesium per 100 g (42% DV), dark chocolate supports normal muscle and nerve function plus hundreds of enzyme reactions.

  3. Cocoa fiber and plant iron

    Per 100 g it offers 8 g of fiber (29% DV) and 6.3 mg of iron (35% DV), supporting digestion and oxygen-carrying red blood cells.
