Is brown sugar healthier than white sugar?
Not in a meaningful nutritional sense. Brown sugar contains molasses and trace minerals, but both are primarily added sugar with very similar calories.
Quick Answer
Brown sugar tastes different because it contains molasses, and that molasses contributes tiny amounts of minerals. But the nutritional difference is too small to turn brown sugar into a health food. Brown and white sugar are both mostly sucrose, provide similar calories and count as added sugar when used in foods. Choose between them for flavor, moisture and recipe behavior, not because one meaningfully changes the health profile of dessert.
By the Numbers
Key Facts
- Main difference
- Brown sugar contains molasses
- Nutrition
- Calories and carbohydrate are very similar
- Practical choice
- Flavor and baking behavior matter more than trace-mineral differences
- Molasses content
- About 3.5% in light brown sugar, 6.5% in dark
White vs. brown sugar, per 100 grams (USDA)
| Per 100 g | White sugar | Brown sugar |
|---|---|---|
| Calories | 387 | 380 |
| Calcium | 1 mg | 83 mg |
| Potassium | 2 mg | 133 mg |
| Iron | 0.05 mg | 0.71 mg |
Brown sugar’s extra minerals come from molasses. They look impressive only because 100 grams is far more sugar than anyone eats at once: matching the roughly 300 mg of calcium in one cup of milk would take about 360 grams of brown sugar.
Molasses changes more than color
Molasses adds moisture, acidity and caramel-like flavor, which can change texture and browning in baked goods.
Trace minerals are still trace
Brown sugar can contain small amounts of minerals that are absent or lower in white sugar, but the serving size of sugar is small and the absolute nutrient contribution is not nutritionally meaningful.
Added sugar is still the category
Whether the crystal is white or brown, adding it to food counts as added sugar. The 2025–2030 Dietary Guidelines for Americans advise keeping added sugars to no more than 10 grams per meal.
Myth vs. Fact
MythBrown sugar is a less processed, natural sugar.
FactMost commercial brown sugar is refined white sugar with molasses added back: about 3.5% for light brown and 6.5% for dark.
MythBrown sugar has fewer calories.
FactThe difference is under 2%: 380 vs. 387 calories per 100 grams.
The Bottom Line
Brown sugar is essentially white sugar with a little molasses: nearly the same calories, and too few minerals to matter. Choose it for flavor and texture, not for health.
