Sugar is a type of carbohydrate that the body uses for energy. It is made up of single or paired molecules known as monosaccharides and disaccharides. Sugar alcohols, on the other hand, are carbohydrates with a chemical structure similar to sugars and alcohols. They are used as sweeteners and bulking agents in food products, particularly those marketed as sugar-free or diabetes-friendly. While sugar alcohols provide sweetness, they have a different chemical structure and are not absorbed as efficiently by the body, resulting in fewer calories and a reduced impact on blood sugar levels compared to regular sugar. This distinction is important as excessive sugar intake has been linked to various health issues, including obesity, heart disease, and diabetes.

What You'll Learn
Sugar and sugar alcohols have different chemical structures
Sugar is a sweet-tasting carbohydrate that the body can convert into energy. Chemically, sugars are made up of carbon, hydrogen, and oxygen atoms. They can be divided into two main categories: monosaccharides (glucose, fructose, and galactose) and disaccharides (sucrose, lactose, and maltose).
Sugar alcohols, also known as polyols, are a type of carbohydrate with a chemical structure that is similar to both sugars and alcohol. However, they do not contain ethanol, and thus, they are safe for individuals who avoid alcohol. Sugar alcohols are found naturally in some fruits and vegetables and are also made by processing regular sugars.
While sugar and sugar alcohols share some similarities in their chemical structures, they also exhibit significant differences. Firstly, sugar alcohols have a different chemical composition, as they contain an alcohol molecule in addition to the sugar molecule. This gives them a slightly different taste, making them generally less sweet than sugars.
Secondly, the presence of the alcohol molecule affects how the body absorbs and metabolizes these compounds. Sugar alcohols are not as efficiently absorbed or digested as regular sugar, which leads to differences in their calorie content and their impact on blood sugar levels. Sugar alcohols contain fewer calories, providing about 2-3 calories per gram compared to 4 calories per gram in sugars. They also cause a slower rise in blood sugar levels, making them suitable for individuals with diabetes.
Lastly, the difference in chemical structure between sugar and sugar alcohols also results in varying effects on oral health. Unlike sugars, sugar alcohols do not contribute to tooth decay and may even help prevent it. They are often used in toothpaste and mouthwash for this reason.
In summary, while sugar and sugar alcohols share some similarities in their chemical structures, they also exhibit significant differences. These differences lead to variations in taste, digestion, calorie content, blood sugar impact, and oral health effects. Understanding these distinctions is crucial when considering the use of sugar alcohols as sugar substitutes in food products and for individuals with specific dietary needs.

Sugar is a type of carbohydrate
Sugar is a sweet-tasting carbohydrate that the body can convert into energy. They are made up of single or paired molecules known as monosaccharides (glucose, fructose, and galactose) and disaccharides (sucrose, lactose, and maltose). Monosaccharides are the simplest type of sugar and contain just one type of sugar molecule.
Sugar alcohols, on the other hand, are a type of carbohydrate with a structure similar to sugars and alcohols. They are also sweet-tasting but have a different chemical structure, and the body does not absorb them as efficiently as sugars. Sugar alcohols include xylitol, erythritol, sorbitol, maltitol, mannitol, isomalt, and lactitol. They are often used as sugar substitutes, providing fewer calories than regular sugar.
While sugar is a carbohydrate, not all sugars are carbohydrates. For example, glucosamine is a sugar that is not a carbohydrate. Additionally, while sugar alcohols are carbohydrates, they do not contain ethanol and are thus different from alcoholic beverages.
Sugar alcohols are found naturally in some fruits and vegetables, such as plums, strawberries, and avocados, and they are also made by processing regular sugars. They are commonly used in processed foods, especially those labelled "sugar-free" or "diabetes-friendly." Sugar alcohols provide sweetness and improve texture, but they can also cause digestive issues when consumed in large quantities.

Sugar alcohols are not true alcohols
Sugar and sugar alcohols are sweet-tasting carbohydrates with slightly different chemical structures. Sugar alcohols are derived from sugars and contain one hydroxyl group (-OH) attached to each carbon atom. They are also referred to as polyhydric alcohols, polyalcohols, alditols, or glycitols.
Sugar alcohols are commonly used as sweeteners in the food industry. They are found in sugar-free chewing gum, candies, processed foods, toothpaste, medications, and laxatives. They are also known as artificial sweeteners, although they are not the same as aspartame and saccharin. Sugar alcohols have very few calories and are not as sweet as sugar. They can be used to mask the unpleasant aftertaste of some high-intensity sweeteners.
Sugar alcohols have a different impact on the body compared to sugars. They are not efficiently absorbed or digested, resulting in fewer calories and a reduced effect on blood sugar levels. However, overconsumption can lead to bloating, flatulence, stomach pain, and diarrhea due to incomplete absorption in the small intestine.
While sugar alcohols have been considered safe, recent research suggests they may increase the risk of heart attack and stroke. A study linked high erythritol intake to weight gain, specifically increased belly fat. Therefore, while sugar alcohols are not true alcohols, their excessive consumption may have adverse health effects.

Sugar alcohols are used as sweeteners
Sugar alcohols are organic compounds derived from sugars. They are called polyols, polyalcohols, alditols, or glycitols. They contain one hydroxyl group attached to each carbon atom. Sugar alcohols are used as sweeteners and thickeners in the food industry. They are used in place of table sugar (sucrose) and in combination with high-intensity artificial sweeteners. Sugar alcohols are not as sweet as sucrose, but they have a similar flavour and can be used to mask the unpleasant aftertaste of some intense sweeteners.
Sugar alcohols are low-calorie sweeteners. They are converted to glucose more slowly than sugar and require little to no insulin to be metabolized. They do not cause sudden spikes in blood sugar levels, making them suitable for people with diabetes. Sugar alcohols are also used in products labelled "diabetes-friendly" or "keto-friendly". They are often found in "sugar-free" products, including hard candies, cookies, chewing gums, soft drinks, and throat lozenges.
Sugar alcohols have about half to one-third fewer calories than regular sugar. They have a different chemical structure and are not absorbed as efficiently by the body. They are not linked to tooth decay and may even help prevent it. They do not react with dental plaque and are not metabolized by oral bacteria.
Sugar alcohols can be produced from renewable resources such as starch, cellulose, and hemicellulose. They can also be made from wood materials or by microbial fermentation. They are commonly used in sugar-free desserts and candies, including ice cream, chocolate, baked goods, and chewing gum.
Some common sugar alcohols include xylitol, erythritol, sorbitol, maltitol, mannitol, isomalt, lactitol, and hydrogenated starch hydrolysates (HSH). While sugar alcohols are generally well-tolerated, consuming large amounts can cause bloating, flatulence, stomach pain, and diarrhea in some individuals.

Sugar alcohols have fewer calories than sugar
Sugar and sugar alcohols are sweet-tasting carbohydrates with slightly different chemical structures. Sugar alcohols are generally less sweet and contain fewer calories than sugars. On average, sugar alcohols supply about 2 calories per gram, compared with the 4 calories per gram supplied by sugars. This is because sugar alcohols are converted to glucose more slowly and require little to no insulin to be metabolized. They also don't cause sudden increases in blood sugar, making them a suitable alternative for people with diabetes.
Sugar alcohols have a structure similar to that of sugars but also contain an alcohol molecule. They are classified as carbohydrates whose structure resembles both sugars and alcohol. However, sugar alcohols do not contain ethanol and are thus safe for people who prefer to avoid alcohol. They are often used as lower-calorie sweeteners in sugar-free chewing gum, candies, and processed foods. Common types of sugar alcohols include xylitol, erythritol, sorbitol, maltitol, mannitol, isomalt, and lactitol.
Sugar alcohols are found naturally in some fruits and vegetables, such as plums, strawberries, and avocados, and are also made by processing regular sugars. They can be added to processed items as sweeteners and bulking agents. Sugar alcohols are often used in products labeled "sugar-free," "low-carb," "diabetes-friendly," or "keto-friendly." They are also added to toothpaste to improve taste and help prevent cavities.
While sugar alcohols have fewer calories than sugar, they are not entirely calorie-free. It is still possible to gain weight when consuming foods containing sugar alcohols, especially in excess. Additionally, sugar alcohols may cause digestive issues such as bloating, flatulence, stomach pain, and diarrhea, especially when consumed in large quantities or by sensitive individuals. Recent research also suggests that sugar alcohols may raise the risk of heart attack and stroke.
