Erythritol is a sugar alcohol
Erythritol is about 70% as sweet as sugar but has zero calories. This is because it is quickly absorbed by the small intestine and excreted from the body through urine within 24 hours, so it does not have a chance to metabolize into energy. Erythritol has a glycemic index of 0, meaning it does not raise blood sugar levels like sugar does. This makes it a good option for people following a keto diet, which involves reducing sugar intake.
However, some people have concerns about the health effects of erythritol and other sugar alcohols. One study found that ingesting erythritol caused a spike in blood levels and increased the stickiness of platelets, which could potentially increase the risk of heart attack, stroke, or other vascular issues. Another study found that erythritol and other sugar alcohols were associated with gastrointestinal effects, including nausea, abdominal bloating, and diarrhea. Overall, while erythritol can be a useful tool for reducing sugar intake, especially on a keto diet, it is important to be aware of any potential side effects and consume it in moderation.

Erythritol is well-tolerated with few side effects
Erythritol is a sugar alcohol, a type of carbohydrate, that is commonly used as a sweetener in 'diet', 'sugar-free', and 'keto-friendly' foods and beverages. It is often made by fermenting the glucose found in cornstarch and has 70% of the sweetness of sugar but with almost zero calories.
Erythritol is well-tolerated by most people and has few side effects. Older feeding studies have shown that consuming 0.7 to 1 gram of erythritol per kilogram of body weight was very well tolerated. However, another study indicated that consuming 50 grams of erythritol in a single dose increased nausea and stomach rumbling. Unless one consumes excessive amounts of erythritol at once, it is unlikely to cause stomach upset. Individual sensitivity to erythritol may vary.
Most of the erythritol consumed is absorbed into the bloodstream and then excreted unchanged in the urine within 24 hours. This rapid excretion means that erythritol doesn't have a chance to metabolize and turn into energy in the body. Erythritol also doesn't affect glucose or insulin levels, making it a suitable option for individuals with diabetes.
While erythritol is generally well-tolerated, some people may experience adverse reactions to sugar alcohols. Additionally, recent research has linked erythritol to an increased risk of blood clots, heart problems, and an enhanced risk of heart attack and stroke. However, more studies are needed to confirm these findings and fully understand the potential health risks associated with erythritol consumption.

Erythritol has close to zero net carbs
Erythritol is a keto-friendly option as it has a glycemic index of 0 and works well in cooking and baking. It has close to zero net carbs and is a good substitute for sugar. It is a sweet, indigestible carbohydrate called a sugar alcohol. Erythritol is usually better tolerated than other sugar alcohols like xylitol, sorbitol, and isomalt.
Erythritol has about 70% of the sweetness of sugar but only 5% of the calories. It is often made by fermenting the glucose found in cornstarch. Due to its small particle size, it is better tolerated than other sugar alcohols. However, some people have reported headaches and fatigue after consuming it.
Erythritol is a good option for those on a keto diet as it does not spike your blood sugar or insulin levels. A Japanese study from 1994 supports this, finding that erythritol did not affect glucose, insulin, cholesterol, triglycerides, or electrolytes. This makes it a good choice for those looking to reduce their sugar intake and maintain a state of ketosis.
However, it is important to note that some people may have negative gastrointestinal side effects from consuming erythritol and other sugar alcohols. Maltitol, for example, has been known to cause stomach issues and can kick you out of ketosis. It is always recommended to consult a healthcare provider before starting any new diet or using new sweeteners.

Erythritol has potential health benefits
Erythritol is a sugar alcohol and a popular artificial sweetener. It is a good option for people on a keto diet as it has a glycemic index of 0 and does not raise blood sugar or insulin levels. It is also suitable for cooking and baking. Erythritol is commonly used as a sugar replacement for people with diabetes as it does not cause cavities and tooth decay, unlike sugar. It is also better tolerated than other sugar alcohols like xylitol and sorbitol.
Erythritol has the same taste as sugar but with no calories, making it a good option for people who are cutting calories or monitoring their sugar intake. It is also a lower-calorie option for people who want to consume less sugar with minimal adverse health effects. Erythritol is also added to sugar substitutes that are sold as "natural" alternatives to sugar.
Erythritol is commonly added to sugar-free products like ice cream, candy, gum, cookies, cakes, protein bars, and fruit spreads. It is also used to bulk up other artificial sweeteners. Erythritol is popular in foods marketed for weight loss and diabetes, and it may be recommended for people with obesity, diabetes, or metabolic syndrome.
However, it is important to note that some people may experience adverse side effects from consuming erythritol, and there is ongoing research into the potential health risks associated with its consumption. While it is generally recognised as safe, more studies are needed to fully understand its long-term effects.
