Sugar alcohols are neither sugar nor alcohol but are carbohydrates with a chemical structure similar to sugar. They are commonly used as low- or zero-calorie sweeteners in food products and are generally recognized as safe by the FDA. Sorbitol, erythritol, and maltitol are three common types of sugar alcohols. Sorbitol is found naturally in fruits and vegetables and is manufactured from corn syrup. It is 50-60% as sweet as sugar and is used as a sweetener in sugar-free foods and drinks. Erythritol is also a common sugar alcohol and sweetener, although research suggests it may increase the risk of heart attack and stroke. Maltitol is made from corn, wheat, and potatoes and is about 75% as sweet as sugar. It is often used in food production as it tastes similar to regular sugar.

Sorbitol, erythritol, maltitol and other sugar alcohols are sugar-free sweeteners
Sugar alcohols are neither sugar nor alcohol but a type of carbohydrate with a chemical structure similar to sugar. They are commonly used as sugar substitutes or artificial sweeteners in food products. Sorbitol, erythritol, maltitol, xylitol, and mannitol are some examples of sugar alcohols. Sorbitol is found naturally in fruits and vegetables and is also manufactured from corn syrup. It is 50% to 60% as sweet as sugar and has a smooth mouthfeel and cool taste. It is commonly used in sugar-free foods and drinks, including jelly spreads and soft candy. Erythritol is another sugar alcohol that is well tolerated and has a sweetness similar to that of sugar. It is one of the most widely used sugar alcohols in the food industry, along with xylitol and maltitol. Maltitol is made from corn, wheat, and potatoes and is about 75% as sweet as sugar. It has a very similar taste and mouthfeel to regular sugar.
While sugar alcohols offer functional and nutritional benefits, they also have potential side effects. For example, sorbitol and maltitol can lead to bloating or laxative effects in high amounts. The European Food Safety Authority (EFSA) has established an acceptable daily intake (ADI) for these sugar alcohols of up to 20 milligrams per kilogram of body weight per day. Additionally, research suggests that sugar alcohols like xylitol and erythritol may increase the risk of heart attack and stroke. A 2023 observational study found a link between the use of erythritol as a sweetener and cardiovascular disease events in people with risk factors like diabetes and high blood pressure.
Sugar alcohols are commonly used in processed foods labelled "sugar-free" or "low sugar", such as hard candies, cookies, chewing gums, soft drinks, and throat lozenges. They provide texture and body to frozen products, reducing the freezing point. However, they are not commonly used in home food preparation. When choosing a sugar substitute, it is important to consider the potential side effects and the acceptable daily intake levels to ensure safe consumption.

Sugar alcohols are carbohydrates, not sugars or alcohols
Sugar alcohols, also known as polyols, are a type of carbohydrate with a chemical structure similar to sugar. They are commonly used as low- or zero-calorie sweeteners and sugar substitutes in food products, particularly those labelled as "sugar-free" or "low sugar". Examples of sugar alcohols include sorbitol, erythritol, maltitol, xylitol, mannitol, and lactitol. These sugar alcohols differ in their sweetness levels, with sorbitol being about 50-60% as sweet as sugar, maltitol being 75% as sweet, and mannitol ranging from 50-70%.
Sorbitol, for instance, is naturally found in fruits and vegetables and is manufactured from corn syrup. It is commonly used in sugar-free foods and drinks, such as jelly spreads and soft candy, as it has a very little effect on blood sugar levels and causes minimal digestive symptoms when consumed in small amounts (under 10 grams). However, consuming larger amounts (over 20 grams) can lead to significant digestive issues, including pain and diarrhoea.
Erythritol is another commonly used sugar alcohol that is well tolerated by the body. However, it has been associated with a heightened risk of cardiovascular events, including heart attack and stroke, especially in individuals with pre-existing heart disease or risk factors such as diabetes and high blood pressure. While erythritol is generally recognised as safe by regulatory bodies like the FDA, excessive consumption of sugar alcohols may cause digestive discomfort in some individuals.
Maltitol, derived from corn, wheat, and potatoes, has a very similar taste and mouthfeel to regular sugar. It contains 2 to 3 calories per gram compared to sugar's 4 calories per gram. While it has a lower glycemic index than sugar, it can still impact blood sugar levels. Like sorbitol, consuming large amounts of maltitol may lead to bloating or laxative effects.
In summary, sugar alcohols are carbohydrates that are used as sweeteners and sugar substitutes. While they offer functional and nutritional benefits, such as providing body and texture to frozen products, they may also carry potential side effects, including digestive issues and, in the case of erythritol, possible long-term health risks. Therefore, it is important to be mindful of the acceptable daily intake guidelines established by regulatory authorities and to avoid excessive consumption of these sugar alcohols.

Sugar alcohols have functional and nutritional benefits
Sugar alcohols are neither sugar nor alcohol but a type of carbohydrate with a chemical structure similar to sugar. They are commonly used as low- or zero-calorie sweeteners in food products and are generally recognised as safe by health authorities like the FDA, the World Health Organization, and the European Union.
Sugar alcohols like maltitol, erythritol, and sorbitol are popular sugar substitutes, providing a similar taste to sugar without the same effect on blood sugar or insulin levels. For instance, maltitol is about 75% as sweet as sugar, while sorbitol is about 50-60% as sweet. Erythritol is better tolerated by the body, whereas sorbitol and maltitol can lead to bloating or laxative effects in high amounts.
One of the functional benefits of sugar alcohols is their ability to alter the texture and hardness of food products, especially frozen desserts, by reducing the freezing point. Sorbitol and erythritol have a more significant impact on the freezing point than maltitol. This property makes sugar alcohols useful in creating the desired body and texture in frozen products.
Nutritionally, sugar alcohols offer a way to enjoy sweet treats without the same caloric, carbohydrate, and insulin impact as sugar. They are often found in sugar-free products, including hard candies, cookies, chewing gums, soft drinks, and throat lozenges. However, excessive consumption of sugar alcohols may cause digestive discomfort, and they have been linked to an increased risk of cardiovascular events, such as heart attacks and strokes, especially for individuals with pre-existing health conditions.
While sugar alcohols provide functional and nutritional benefits, it is important to consume them in moderation and be aware of potential side effects, especially for those with specific health concerns.

Sugar alcohols are generally safe but may cause digestive issues in high amounts
Sugar alcohols, also known as polyols, are ingredients used as sweeteners and bulking agents. They are popular among individuals with diabetes as they provide fewer calories (about half to one-third fewer) than regular sugar. This is because they are converted to glucose more slowly, require little to no insulin to be metabolized, and don't cause sudden increases in blood sugar. Common sugar alcohols include mannitol, sorbitol, xylitol, lactitol, isomalt, maltitol, erythritol, and hydrogenated starch hydrolysates (HSH).
While sugar alcohols offer functional and nutritional benefits, they may cause digestive issues in high amounts. Their slow digestion can lead to fermentation and excess gas, pulling extra water into the colon and causing a laxative effect. This can result in bloating and diarrhea, with individual tolerance varying based on factors such as body weight, health conditions, and the type and amount of sugar alcohol consumed. The European Food Safety Authority (EFSA) has established an acceptable daily intake (ADI) of up to 20 milligrams per kilogram of body weight per day for xylitol, erythritol, sorbitol, and maltitol.
Food products labeled "sugar-free" or "diabetes-safe" often contain sugar alcohols, including hard candies, cookies, chewing gums, soft drinks, and throat lozenges. While these products can aid in reducing carbohydrate intake, excessive consumption may lead to weight gain and adverse health effects. It is recommended to introduce sugar alcohols gradually into the diet and monitor how the body responds.
Recent research has raised concerns about the potential health risks associated with sugar alcohols, particularly xylitol and erythritol. Studies suggest that elevated levels of these sugar alcohols may increase the risk of "major adverse cardiovascular events," including heart attacks and strokes. However, it is important to note that association does not equal causation, and more research is needed to fully understand their impact on health.
In conclusion, while sugar alcohols are generally considered safe and provide benefits for individuals with diabetes, they may cause digestive issues when consumed in high amounts. It is important to consume products containing sugar alcohols in moderation and focus on incorporating whole foods into the diet whenever possible.

Sugar alcohols are commonly used in processed foods
Sorbitol, for example, is found naturally in fruits and vegetables and is about 50-60% as sweet as sugar. It has a smooth mouthfeel and a cool taste, with about 60% of the calories of sugar. It has a very little effect on blood sugar and causes minimal digestive symptoms when consumed in small amounts (under 10 grams). However, consuming more than 20 grams of sorbitol can cause significant digestive issues, including pain and diarrhoea.
Erythritol is another commonly used sugar alcohol and is often chosen as a sugar substitute due to its similarity in taste to sugar. Research suggests that erythritol may raise the risk of heart attack and stroke, with a 2023 observational study finding a link between erythritol consumption and cardiovascular disease events in people with risk factors such as diabetes and high blood pressure. However, it is generally well-tolerated and does not cause the same bloating or laxative effects as sorbitol and maltitol.
Maltitol is also widely used in food production and is about 75% as sweet as sugar. It has a similar taste and mouthfeel to regular sugar. However, it is poorly absorbed by the small intestine and therefore does not have the same effect on blood sugar or insulin levels as sugar. Like sorbitol and erythritol, excessive consumption of maltitol may lead to digestive discomfort.
Overall, sugar alcohols are popular in the food industry due to their functional and nutritional benefits, providing sweetness with fewer calories and a lower impact on blood sugar. However, it is important to be aware of potential side effects, such as digestive issues and, in the case of erythritol, possible long-term health risks.
