Coconut Sugar and the Glycemic Index: What People with Diabetes Need to Know
Is coconut sugar truly a healthier sweetener for diabetes? Discover its glycemic index, nutrition, and impact on blood sugar.
Coconut sugar has gained popularity as a seemingly healthier alternative to table sugar, often promoted for its lower glycemic index (GI) and natural origins. But how does it truly compare to regular sugar, especially for people with diabetes or anyone mindful of their blood sugar? This article explores coconut sugar’s nutritional profile, its effects on blood glucose, and whether its reputation as a superior sweetener holds up to scrutiny.
Understanding Coconut Sugar
Coconut sugar, sometimes called coconut palm sugar, is a natural sweetener derived from the sap of the flower buds of the coconut palm. It has been used for generations in Southeast Asia as both a culinary ingredient and a traditional remedy. In recent years, it has become a trendy export marketed as a ‘healthier’ sugar replacement in Western countries.
- Produced by collecting sap from coconut palm flower buds and evaporating it until it crystallizes.
- Commonly found in natural food stores, often in granulated form similar to brown sugar.
- Used in drinks, cooking, and baking as a substitute for cane or table sugar.
Key Characteristics of Coconut Sugar
| Attribute | Coconut Sugar | Cane Sugar |
|---|---|---|
| Color | Dark brown, similar to brown sugar | White (table sugar), brown (brown sugar) |
| Taste | Cara-melized, less sweet than cane sugar | Sweet, neutral |
| Refinement | Less refined | Highly refined (white sugar) |
| Availability | Natural and specialty food stores | Ubiquitous (grocery stores) |
| Price | Generally more expensive | Lower cost |
What Is the Glycemic Index?
The glycemic index (GI) is a scale measuring how quickly a carbohydrate-containing food raises blood glucose. It is especially important for people with diabetes, as controlling blood sugar spikes is a key component of disease management.
- Low GI: 55 or less
- Medium GI: 56–69
- High GI: 70 or above
Foods with a low GI value are generally absorbed more slowly, resulting in a smaller rise in blood sugar. Various factors can influence a food’s GI, such as fiber content, processing, and the types of sugars present.
Coconut Sugar Glycemic Index: Comparison with Other Sweeteners
Coconut sugar is widely reported to have a GI of approximately 54, placing it just below the threshold for the “medium” GI rating and making it somewhat lower than regular table sugar.
| Sweetener | Glycemic Index (GI) |
|---|---|
| Coconut Sugar | ~54 |
| Table Sugar (Sucrose) | ~60 (can range 50–84) |
| Cane Sugar | ~50 (can range 55–84) |
| White Sugar | 58–84 |
| Honey | 35–87 (varies) |
| Glucose | 96–114 |
While coconut sugar does have a lower GI than many other sweeteners, research shows the practical difference in blood sugar impact may be modest, especially for people with diabetes. GI values can also vary between individuals and depending on the specific batch of coconut sugar.

How Does Coconut Sugar Affect Blood Sugar?
Coconut sugar is made up primarily of sucrose (about 80–90%), with small amounts of free glucose and fructose. Despite some differences in GI, its chemical makeup means it still has a significant impact on blood glucose levels. Studies show:
- Coconut sugar can cause blood glucose to rise, though sometimes less dramatically than table sugar.
- According to a recent study of people with type 2 diabetes, blood sugar responses to coconut sugar and cane sugar were not significantly different.
- It should still be considered an added sugar and consumed in moderation.
- The small amount of dietary fiber (inulin) in coconut sugar may slow down sugar absorption slightly, but not enough to make it a diabetic-friendly sweetener.
Nutrition Facts: Coconut Sugar vs. Table Sugar
Coconut sugar is marketed as more nutrient-rich than refined sugars. It retains trace amounts of nutrients found in the coconut palm, offering small amounts of:
- Iron
- Zinc
- Calcium
- Potassium
- Phytonutrients such as antioxidants and polyphenols
However, the health benefits of these nutrients are negligible, since you would need to consume large and unhealthy amounts of coconut sugar to meet daily requirements.
| Nutrient | Coconut Sugar (1 tsp) | Table Sugar (1 tsp) |
|---|---|---|
| Calories | ~15–20 | ~15–20 |
| Carbohydrates | ~4 g | ~4 g |
| Sugars | ~4 g (mostly sucrose) | ~4 g (mostly sucrose) |
| Minerals and Antioxidants | Tiny amounts (iron, zinc, potassium) | Negligible |
| Fiber | Tiny amount (inulin) | None |
The bottom line: Coconut sugar is not a meaningful source of vitamins or minerals. Rather than relying on it for key nutrients, aim to fulfill those needs with whole foods.
Is Coconut Sugar Better for People with Diabetes?
Despite its frequent portrayal as a healthier sugar, the scientific evidence does not strongly support coconut sugar as an ideal sweetener for people with diabetes. Here’s why:
- Its impact on blood sugar is still significant due to its high sucrose content.
- Its slightly lower GI does not equate to a substantial health benefit.
- Clinical studies indicate no significant difference in blood sugar spikes when substituting coconut sugar for cane sugar in people with diabetes.
- Coconut sugar, like all added sugars, should be limited in any diet focused on blood sugar control.
The American Diabetes Association and other experts recommend limiting consumption of all added sugars, including natural ones like coconut sugar, to less than 10% of total daily calories.
Potential Health Risks of Added Sugar (Including Coconut Sugar)
- Weight gain and obesity
- Worsening insulin resistance
- Increased risk for type 2 diabetes
- Cardiovascular disease
Using coconut sugar in place of other sugars is not a license to use sweeteners liberally.
Myths and Marketing Hype: Is Coconut Sugar the Healthier Choice?
Marketing often presents coconut sugar as a natural, safe, or even beneficial sweetener, but these claims warrant skepticism:
- It is less refined than table sugar, but this does not significantly change its nutritional or metabolic impact.
- The small difference in GI has limited practical benefit for blood sugar management.
- Its nutrient content is minimal and does not provide significant health advantages.
When evaluating sugar substitutes, it’s important to look beyond buzzwords like “natural”, “organic”, or “unrefined” and instead focus on the objective impact on blood sugar and overall health.
Can You Use Coconut Sugar as a Sugar Substitute?
Coconut sugar can be swapped directly for cane sugar or white sugar in most recipes, but keep in mind:
- It has a caramel-like flavor, which may subtly change the taste of recipes.
- It is less sweet than white sugar, so recipe results may vary.
- It is generally more expensive and less widely available than regular sugar.
For people aiming to lower overall sugar intake, simply substituting coconut sugar for cane sugar does not reduce total carbohydrate load or calories.
Quick Tips for Managing Sugar Intake
- Moderation is key: Limit all forms of added sugar, including coconut sugar, to under 10% of total daily calories.
- Focus on whole foods: Fruits, vegetables, whole grains, and legumes provide natural sweetness and vital nutrients with a lower risk of blood sugar spikes.
- Read labels: “Natural” sweeteners can still contribute to your total sugar intake.
- Consult a dietitian or diabetes educator before making major changes to your diet or sweetener choices.
