Xylitol is a sugar alcohol that is used as a sugar substitute. It looks and tastes like sugar, but has fewer calories. Xylitol is found naturally in some fruits and vegetables, and can also be manufactured. It is commonly used in sugar-free gum, candy, baked goods, and oral health products like toothpaste. Understanding the calorie content of xylitol can help people monitor their calorie and sugar intake. This article will provide a detailed look at how many calories are in a teaspoon of xylitol.
What is Xylitol?
Xylitol is classified as a sugar alcohol or polyol. Its chemical structure is similar to sugar, but slightly different. This difference prevents xylitol from being fully broken down and absorbed by the body. Xylitol contains 2.4 calories per gram, while regular table sugar contains 4 calories per gram.
Some key facts about xylitol:
– Xylitol has a sweetness similar to regular sugar but contains fewer calories per gram. It has about 40% fewer calories than sugar.
– It does not increase blood sugar or insulin levels as much as regular sugar. Therefore, it has a minimal effect on blood sugar and insulin levels.
– Xylitol is not fully broken down during digestion. It is only partially absorbed by the body (about 50%).
– Since it is only partially digested, xylitol has 30-40% fewer calories than sugar per gram.
– Xylitol has been shown to help prevent cavities and promote dental health.
– The glycemic index of xylitol is very low (7), compared to regular table sugar (65).
– Xylitol contains zero fructose.
Xylitol Calorie Content
Since xylitol contains 2.4 calories per gram, we can calculate how many calories are in a teaspoon of xylitol:
– 1 teaspoon of xylitol weighs about 4 grams
– Xylitol contains 2.4 calories per gram
– So 1 teaspoon (4 grams) of xylitol contains:
4 grams x 2.4 calories/gram = 9.6 calories
Therefore, there are about 9-10 calories in a teaspoon of xylitol.
This is significantly lower than the calories in a teaspoon of regular white sugar, which provides about 16 calories per teaspoon (4 grams of sugar x 4 calories/gram = 16 calories).
Calorie breakdown for different measures of xylitol:
| Xylitol Measure | Grams | Calories |
|---|---|---|
| 1 teaspoon | 4 grams | 9.6 calories |
| 1 tablespoon (3 teaspoons) | 12 grams | 28.8 calories |
| 1 cup | 120 grams | 288 calories |
Benefits of Xylitol
Some of the main benefits of xylitol compared to regular sugar include:
– Fewer calories and carbs – Xylitol only contains 2.4 calories per gram, vs 4 calories in sugar. This results in 40% fewer calories.
– Does not spike blood sugar – Xylitol has minimal impact on blood glucose and insulin levels.
– Tooth-friendly – Xylitol is non-fermentable and helps prevent cavities. It reduces cavity-causing bacteria in the mouth.
– Prebiotic effects – Xylitol may act as a prebiotic by feeding the good bacteria in the gut. This could improve digestive health.
– Low glycemic impact – Xylitol only raises blood sugar levels slightly compared to regular sugar. Its glycemic index is only 7 compared to sugar which is 65.
– Anti-inflammatory – Xylitol has been found to reduce inflammation levels in some animal studies.
– Bone health – Some research shows xylitol may increase bone volume and bone mineral content, improving bone density.
So using xylitol instead of sugar can provide a pleasantly sweet taste with reduced calorie intake and other health benefits. Just be aware that large amounts of xylitol can have a laxative effect.

Using Xylitol in Cooking and Baking
Xylitol can be substituted for sugar in many recipes. However, keep these tips in mind:
– Use 3/4 cup of xylitol for every 1 cup of sugar called for in recipes. Xylitol is not as sweet as regular sugar.
– Reduce liquids in the recipe by 1/4 to 1/3. Xylitol does not caramelize or brown the same way as sugar.
– Add 1/2 to 1 teaspoon of baking soda per cup of xylitol used. This helps recipes rise properly.
– Reduce oven temperature by 25°F as items with xylitol can brown faster.
– Xylitol may not perform as well in recipes with yeast, since it does not feed yeast growth as well as sugar.
– Bake times may be slightly shorter when using xylitol instead of regular sugar.
So xylitol can be used in place of sugar in recipes, with some adjustments to amounts and methods. Be sure to check finished products earlier for proper doneness.
Xylitol Content in Common Foods
While xylitol is manufactured commercially, it also occurs naturally in small amounts in some fruits and vegetables. Here are some examples of xylitol content in foods:
| Food | Serving Size | Grams of Xylitol |
|---|---|---|
| Raspberries | 1 cup | 0.012 grams |
| Strawberries | 1 cup | 0.031 grams |
| Cauliflower | 1 cup | 0.13 grams |
| Yellow plums | 1 plum | 0.037 grams |
As you can see, the xylitol content from natural food sources is very small. To consume therapeutic amounts of xylitol, a person would need to eat large quantities of these fruits and vegetables.
Manufactured xylitol is added to products like chewing gum, breath mints, cough drops and nasal sprays. These contain significantly more xylitol per serving compared to natural sources. For example, one piece of xylitol gum may contain 1 gram of xylitol.
Is Xylitol Considered a Healthy Sugar Substitute?
Overall, xylitol is considered one of the more tooth-friendly and lower calorie sweeteners. It scores very low on the glycemic index scale and does not spike blood sugar or insulin compared to regular sugar.
Some key considerations:
– Xylitol can help prevent dental cavities and reduce cavity-causing bacteria. This makes it a smart choice for improving dental health.
– With 2.4 calories per gram, xylitol contains 40% fewer calories compared to table sugar. This can help reduce daily calorie intake.
– Xylitol does not raise blood sugar or insulin levels as dramatically as regular sugar. However, it still impacts blood glucose more than non-nutritive sweeteners like stevia.
– Xylitol may cause digestive side effects like gas, bloating and diarrhea when consumed in large amounts. Start with small amounts and increase slowly.
– There is controversy surrounding xylitol’s effects on dogs. Xylitol is thought to be toxic to dogs. Thus, products containing xylitol should be kept away from dogs.
So while xylitol has some benefits, it should still be used moderately as part of an overall healthy diet. Other no-calorie sweeteners like stevia and monk fruit may be better choices for those looking to restrict carbs and calories.
Xylitol Safety and Side Effects
Xylitol is generally well tolerated in humans when consumed in normal food amounts. However, there are some side effects to be aware of:
– Digestive side effects: Consuming large amounts of xylitol may cause digestive issues like gas, bloating, diarrhea and cramps. Start with small amounts and increase intake slowly.
– Allergic reactions: Though rare, some people may experience allergic reactions to xylitol. Symptoms include hives, swelling, wheezing and difficulty breathing.
– Hypoglycemia: There is a theoretical risk that large doses of xylitol could cause low blood sugar in susceptible individuals. This is most likely with doses over 50 grams.
– Dental erosion: While xylitol can help prevent cavities, some evidence shows overuse may erode tooth enamel over time. This occurs with extremely high intake amounts.
– Intestinal changes: Some studies in rats and mice show xylitol can alter absorption and gut microbiota. The relevance in humans is still unclear. More research is needed.
– Dogs: Xylitol is thought to be harmful to dogs as their bodies may mistake it for real sugar. It can cause insulin release and dangerous blood sugar crashes in canines. Keep xylitol out of reach from dogs.
When consumed moderately as part of a varied diet, xylitol appears safe for healthy adults and children over 2 years old. However, those with diabetes, gut conditions or on medications should consult their doctor before use.
