Is Dark Chocolate Healthier Than Milk Chocolate?

Short answer: Yes. Dark chocolate (70%) has half the sugar of milk chocolate (24 vs 52 g per 100 g) and about three times the fiber. It's still calorie-dense and high in saturated fat — a couple of squares is the sweet spot.

Nutrition side by side

Rounded averages from food composition tables (USDA FoodData Central and others) for the foods as eaten; brands and recipes vary.

Which wins, and when

• Less energy: Milk chocolate — 63 kcal less per 100 g than dark chocolate.
• More fiber: Dark chocolate — 7.6 g more per 100 g than milk chocolate.
• Less sugar: Dark chocolate — 28 g less per 100 g than milk chocolate.
• Less saturated fat: Milk chocolate — 6 g less per 100 g than dark chocolate.

In short: for fewer calories or less saturated fat, look at the “less” lines; for staying full longer, protein and fiber matter most. Goals like lower sugar, more protein or more omega-3 can be set in the diary, and swaps there are ranked for that goal.

Blood sugar angle

Dark chocolate has 46 g of carbohydrate per 100 g (24 g sugars, 11 g fiber); Milk chocolate has 59 g (52 g sugars, 3.4 g fiber). As a rule of thumb, more fiber and protein alongside the carbs means a gentler rise in blood sugar, while sugary drinks and refined starches hit faster. Glycemic index values vary by variety, ripeness and cooking, so treat any single number with caution — and eat either with vegetables and some protein.

Portion tips

• Dark Chocolate: a typical serving (three squares, 25 g) is 150 kcal — about 49 min of easy walking for a 70 kg (154 lb) person.
• Milk Chocolate: a typical serving (three squares, 25 g) is 134 kcal — about 44 min of easy walking.

Portion size usually moves the numbers more than the choice between two similar foods: a heaping serving of the “healthier” one can easily outweigh a modest serving of the other.
