Demerara Sugar: Separating Fact from Marketing
Demerara sugar is a type of cane sugar that undergoes minimal processing, which allows it to retain some of its natural molasses content and give it a characteristic light brown color, larger crystals, and caramel-like flavor. This less-refined status often creates a "health halo," leading many to believe it is significantly better for you than white granulated sugar. However, from a nutritional and dietary perspective, this perception is a myth that requires closer examination. The disadvantages of consuming demerara sugar, especially in excess, align closely with those of any other added sugar.
High Calorie and Sugar Content
One of the most significant disadvantages is that, despite being less processed, demerara sugar contains virtually the same number of calories and carbohydrates as regular white sugar. Both contain approximately 4 calories per gram. Substituting demerara for white sugar will not reduce your calorie intake and, in turn, will not help with weight management. Excessive consumption of any form of added sugar contributes to a surplus of calories, which can lead to weight gain and obesity.
Significant Impact on Blood Sugar
Another major concern for consumers is demerara sugar's effect on blood glucose levels. Like all added sugars, demerara is a high-glycemic food. This means it causes a rapid increase in blood sugar and insulin levels after consumption, an effect very similar to that of white sugar. Frequent, dramatic spikes in blood sugar can contribute to insulin resistance over time, which increases the risk of developing type 2 diabetes. For individuals with existing diabetes, demerara sugar poses the same risks as other sugars and should be consumed with extreme caution.
Negligible Nutritional Value
The trace amounts of vitamins and minerals found in demerara sugar are often highlighted as a benefit, but this is nutritionally misleading. The levels of calcium, magnesium, and iron retained from the molasses are so small that they contribute negligibly to a person's daily nutrient requirements. To gain any significant nutritional benefit, one would need to consume an unhealthy amount of the sugar, and at that point, the negative health effects from the high sugar content would far outweigh any minor gains from the trace minerals. A balanced diet rich in whole foods, like fruits and vegetables, is a far superior source of vitamins and minerals.
Demerara vs. White Sugar: A Nutritional Comparison
| Feature | Demerara Sugar | White Granulated Sugar |
|---|---|---|
| Processing Level | Minimally processed | Highly refined |
| Nutritional Value | Trace amounts of minerals (negligible) | No nutritional value (empty calories) |
| Calories (per tsp) | ~15 calories | ~15 calories |
| Glycemic Impact | High, similar to white sugar | High |
| Crystal Size | Large, coarse crystals | Small, fine crystals |
| Flavor | Mild caramel/toffee notes | Neutral sweetness |
Associated Health Risks
Excessive sugar consumption, regardless of the source, is a leading contributor to a number of serious health problems. Using demerara sugar as a "healthy" alternative can mask the fact that you are still putting yourself at risk for these conditions:
- Obesity: The high calorie count from added sugars is a primary driver of weight gain.
- Type 2 Diabetes: Frequent blood sugar spikes can lead to insulin resistance.
- Heart Disease: Research has linked excessive sugar consumption to an increased risk of cardiovascular issues.
- Inflammation: A high-sugar diet can lead to cellular inflammation and increase the risk for atherosclerosis.
- Fatty Liver Disease: Overloading the body with fructose from sugar can contribute to non-alcoholic fatty liver disease.
- Dental Decay: All sugars feed the bacteria in your mouth that cause cavities and tooth decay.
Culinary Limitations
Beyond the health implications, the physical characteristics of demerara sugar can present challenges in the kitchen. Its large, coarse crystals do not dissolve easily in certain baked goods, potentially leaving a grainy texture in cakes and smooth batters. While this crunchy texture can be desirable for toppings, it limits its versatility in cooking and baking. The mild caramel or toffee flavor can also subtly alter the final taste of a dish, which may not be a desired effect in all recipes.
Conclusion: The Bottom Line on Demerara Sugar
Ultimately, the idea that demerara sugar is a healthy sugar substitute is largely a misconception driven by marketing. While its minimal processing allows it to retain trace minerals and a pleasant flavor, these benefits are outweighed by its high sugar and calorie content. The disadvantages of demerara sugar—its contribution to weight gain, blood sugar spikes, and risk of chronic diseases—are the same as those of any other added sugar. For those seeking to reduce their sugar intake, the focus should be on moderation and choosing natural sources of sweetness from whole foods, rather than simply swapping one form of added sugar for another.

How to Limit Your Added Sugar Intake
- Read Labels: Always check food and drink labels for added sugars, including demerara and other forms like turbinado or brown sugar.
- Choose Whole Foods: Focus on naturally sweet whole foods like fruits, which also provide fiber and other essential nutrients.
- Cook at Home: Preparing your own meals gives you control over the amount and type of sugar you add.
- Use Alternatives Sparingly: If using sweeteners, remember that even "natural" options like honey or maple syrup are still concentrated sugars and should be used sparingly.
