Sugar alcohol is a type of sweetener that is commonly used as a substitute for sugar in many food products. It is a low-calorie alternative to sugar and is often used by people who are looking to reduce their sugar intake. However, the question remains: how healthy is sugar alcohol?
Sugar alcohol is a type of carbohydrate that is found naturally in some fruits and vegetables. It is also produced commercially from sugars and starches. Unlike regular sugar, sugar alcohol is not fully absorbed by the body, which means it provides fewer calories per gram. This makes it an attractive alternative to sugar for people who are looking to manage their weight or blood sugar levels. However, sugar alcohol is not without its drawbacks, and it is important to understand the potential health risks associated with its consumption.
Understanding Sugar Alcohols
Chemical Structure
Sugar alcohols are a type of carbohydrate that are commonly used as sugar substitutes. They are called sugar alcohols because their chemical structure is a combination of a sugar molecule and an alcohol molecule. Unlike regular sugar, sugar alcohols are not completely absorbed by the body, which means they have a lower calorie count and do not raise blood sugar levels as much as regular sugar.
Types of Sugar Alcohols
There are several types of sugar alcohols, including erythritol, xylitol, sorbitol, mannitol, lactitol, and maltitol. Each type has a different level of sweetness and calorie count, and they are often used in combination with each other to achieve a desired level of sweetness and texture in food products.
Erythritol is a sugar alcohol that is made from cornstarch and has a sweetness level that is about 70% that of regular sugar. It has a very low calorie count and does not affect blood sugar levels, which makes it a popular sugar substitute for people with diabetes.
Xylitol is another popular sugar alcohol that is commonly used in sugar-free gum and toothpaste. It has a sweetness level that is about the same as regular sugar and a calorie count that is about half that of regular sugar.
Sorbitol is a sugar alcohol that is commonly used in sugar-free candy and chewing gum. It has a sweetness level that is about 60% that of regular sugar and a calorie count that is about two-thirds that of regular sugar.
Mannitol is a sugar alcohol that is commonly used in sugar-free chocolate and other confectionery products. It has a sweetness level that is about 50% that of regular sugar and a calorie count that is about half that of regular sugar.
Lactitol is a sugar alcohol that is commonly used in sugar-free ice cream and other frozen desserts. It has a sweetness level that is about 30% that of regular sugar and a calorie count that is about two-thirds that of regular sugar.
Maltitol is a sugar alcohol that is commonly used in sugar-free baked goods and other confectionery products. It has a sweetness level that is about 90% that of regular sugar and a calorie count that is about two-thirds that of regular sugar.
Overall, sugar alcohols are a popular sugar substitute because they have a lower calorie count and do not raise blood sugar levels as much as regular sugar. However, they can cause gastrointestinal problems if consumed in high amounts, so it is important to consume them in moderation.
Health Impacts of Sugar Alcohols
Glycaemic Index
Sugar alcohols have a low glycaemic index (GI) compared to regular sugar. This means that they do not cause a rapid increase in blood sugar levels. Hence, sugar alcohols are suitable for individuals with diabetes or those on a low-carbohydrate diet. However, some sugar alcohols such as maltitol have a higher GI and can cause a spike in blood sugar levels.
Dental Health
Sugar alcohols are less cariogenic than regular sugar, meaning they are less likely to cause tooth decay. They do not feed the bacteria that cause plaque and cavities. In fact, some sugar alcohols such as xylitol can even reduce the risk of dental caries by inhibiting the growth of oral bacteria.
Digestive Considerations
Sugar alcohols are not completely absorbed by the body, which means that they can cause digestive issues such as bloating, gas, and diarrhoea. However, the severity of these symptoms varies depending on the individual, the type of sugar alcohol consumed, and the amount consumed.
Caloric Content
Sugar alcohols have fewer calories than regular sugar, making them a suitable alternative for individuals looking to reduce their calorie intake. However, they are not completely calorie-free and can still contribute to weight gain if consumed in excess.
Overall, sugar alcohols can be a healthier alternative to regular sugar, but they should still be consumed in moderation. It is important to note that some individuals may experience digestive issues when consuming sugar alcohols, and they should consult their healthcare provider before consuming them.
