Sugar Alcohol And Keto: What's The Verdict?

Sugar alcohols are sweeteners that have tastes and textures similar to those of sugar, but with fewer calories and a less significant effect on blood sugar levels. They are commonly used as sugar substitutes and are often used as an alternative to table sugar (sucrose) because they are sweet-tasting but can claim no sugar is added on the packaging. Sugar alcohols are found in products labelled sugar-free (drinks, gum, and food), as well as naturally in certain fruits and vegetables.

Sugar alcohols are a mixture of alcohol and sugar molecules. They don’t contain ethanol so you won’t get drunk consuming them, and they don't contain sugar so you won't get energy from them. Sugar alcohols are often used as sugar substitutes in food products because they are difficult to digest and are slow to metabolize.

Sugar alcohols can be a satisfying option for individuals looking to reduce their sugar intake, such as those following a keto diet. However, it's important to note that not all sugar alcohols are created equal and some may cause digestive issues such as bloating, nausea, and diarrhea.

Erythritol is keto-friendly, with a glycemic index of 0

Erythritol is a keto-friendly sugar alcohol with a glycemic index of 0. This means it has a negligible effect on blood sugar levels, making it a good choice for people following a ketogenic diet.

Erythritol is a type of food additive and sugar alcohol, which is a class of compounds with a chemical structure similar to glucose but with an attached hydroxyl group (-OH) or alcohol group. It is often made by fermenting the glucose found in corn starch or wheat starch, resulting in a product that looks like powdery white crystals.

As a sugar alcohol, erythritol has a much lower calorie content than table sugar. It provides only about 6% of the calories found in an equal amount of sugar, with 0.24 calories per gram compared to 4 calories per gram for table sugar. This is because erythritol is absorbed quickly by the small intestine and excreted from the body through urine within 24 hours, so it doesn't have a chance to metabolize into energy.

In addition to being low in calories, erythritol also has a sweet taste similar to table sugar. It provides 70% of the sweetness of sugar while containing only a fraction of the calories. This makes it a popular choice as a sugar substitute, especially in foods marketed for weight loss and diabetes management.

Not only is erythritol keto-friendly, but it also offers potential health benefits. For example, it may improve oral health by suppressing the growth of bacteria in the mouth and reducing the formation of dental plaque and cavities. Additionally, erythritol does not raise blood sugar levels, making it a suitable option for people with diabetes or insulin resistance.

However, it's important to note that some people may experience side effects from consuming large amounts of erythritol. These side effects can include mild to severe digestive issues such as bloating, cramping, excess gas, and diarrhea. There is also some research suggesting a possible link between erythritol consumption and an increased risk of heart attack, stroke, and blood clots. Therefore, while erythritol can be a useful tool for managing blood sugar and weight, it should be consumed in moderation as part of a balanced diet.

Xylitol is mostly tolerated but can cause a slight increase in blood glucose levels

Xylitol is a sugar alcohol that is commonly used as a sweetener in foods and medications. It is well tolerated by the body and does not cause a significant rise in blood sugar levels, making it a suitable alternative for people with diabetes or metabolic problems.

However, it is important to note that xylitol can cause a slight increase in blood glucose levels. This is because xylitol is metabolised in the liver and can be converted to xylulose 5-phosphate, which activates carbohydrate response element binding protein and promotes the transcription of lipogenic enzyme genes. This process may contribute to increased insulin levels and a slight rise in blood glucose.

Despite this, xylitol is still considered a better option than regular sugar for individuals following a keto diet or looking to manage their blood sugar levels. This is because it has a much lower glycemic index than regular sugar, meaning it does not cause a rapid spike in blood sugar levels. Additionally, xylitol has 40% fewer calories than regular sugar, making it a weight-loss-friendly option.

Overall, while xylitol may cause a slight increase in blood glucose levels, it is still a healthier alternative to regular sugar and is generally well tolerated by most individuals.

Maltitol and sorbitol are not keto-friendly and can cause severe GI issues

Sugar alcohols are often used as sugar substitutes in food products because they are difficult to digest and have a low-calorie content. While they are considered to be keto-friendly, some are better options than others.

Maltitol and sorbitol are two sugar alcohols that should be avoided on a ketogenic diet. They are partially digested, which causes an increase in blood glucose levels, and can cause severe gastrointestinal issues.

Maltitol is a sugar alcohol commonly used as a low-calorie alternative to table sugar in candies, baked goods, and other foods. It is about 90% as sweet as sugar. However, maltitol has a glycemic index of up to 52, which means it can significantly affect your blood sugar levels. Consuming products with maltitol can cause you to inaccurately count net carbs, potentially kicking you out of ketosis.

Maltitol is also known to cause gastrointestinal issues, even in small doses. It draws water from your gastrointestinal tract, which can lead to bloating, gas, stomach pains, cramping, and diarrhea. Many sugar-free candies and "keto-friendly" products contain maltitol, but these should be avoided as they can kick you out of ketosis and cause digestive problems.

Sorbitol is another sugar alcohol that is only partially absorbed in the small intestine, with the rest being fermented by bacteria. It can impact blood sugar levels because it is fully metabolized, although very slowly. It is also associated with gastrointestinal side effects, especially at higher dosages.

In summary, while sugar alcohols are generally considered keto-friendly, maltitol and sorbitol are two notable exceptions. They can cause a significant increase in blood glucose levels and severe gastrointestinal issues, including bloating, gas, stomach pains, and diarrhea. It is best to avoid these sugar alcohols and choose other keto-friendly sweeteners instead.

Sugar alcohols are not fully digestible, and keto dieters often subtract them from total carbs

Sugar alcohols are sugar compounds that have a chemical structure similar to glucose but with a hydroxyl group (-OH, or alcohol group) attached. They are commonly used as sugar substitutes and are often used as an alternative to table sugar (sucrose) because they are sweet-tasting but can claim no sugar is added on the packaging. Sugar alcohols are found in products labelled as sugar-free (such as drinks, gum, and food), as well as naturally occurring in certain fruits and vegetables.

Sugar alcohols are often used as sugar substitutes in food products because they are difficult to digest and slow to metabolize. This is due to the presence of the alcohol group in the area typically occupied by a carbonyl group in sugars. This also prevents polyols from being broken down by salivary amylases and fermented by bacteria found in plaque, both of which contribute to the production of acid and caries.

Because of this, most sugar alcohols are only partially digested and thus yield fewer calories and carbohydrates. Sugar alcohols are often commercially manufactured as a low-calorie way to sweeten food products. Common sugar alcohols include erythritol, isomalt, maltitol, sorbitol, and xylitol.

Sugar alcohols are not fully digestible, and keto dieters often subtract them from the total number of carbs in a food item. This number is referred to as net carbs. However, it is important to note that not all sugar alcohols are treated equally when calculating net carbs. Erythritol, for example, can be fully subtracted from the total carbohydrate content since it is not metabolized by the body. On the other hand, xylitol can only be partially subtracted, as it is absorbed and metabolized by the body.

It is also worth noting that sugar alcohols can cause digestive issues, especially in larger amounts. Side effects such as bloating, nausea, and diarrhea have been observed when intake exceeds 35-40 grams per day. Individuals with irritable bowel syndrome (IBS) may experience negative side effects with any amount of sugar alcohols and may want to avoid them altogether.

Sugar alcohols are commonly found in sugar-free products and some fruits and vegetables

Sugar alcohols are commonly used as sugar substitutes in sugar-free products and some fruits and vegetables. They are often used as an alternative to table sugar (sucrose) because they are sweet-tasting but can be labelled as having "no sugar added". They are also advertised as having zero calories per gram.

Sugar alcohols are found in products labelled "sugar-free" (such as drinks, gum, and food) and occur naturally in certain fruits and vegetables. Pineapples, olives, asparagus, sweet potatoes, and carrots are natural sources of mannitol; cereals, mushrooms, and some fruits and vegetables contain xylitol; and various fruits like apples, pears, blackberries, peaches, and prunes contain sorbitol.

Sugar alcohols are also added to foods, including baking mixes, cereals, and ice cream, to give them a sweet taste without the negative side effects associated with regular sugar. They are considered to be low-calorie sweeteners and are about 25–100% as sweet as sugar, but with 50–60% of the calories.

Sugar alcohols are often used to sweeten sugar-free or diet products like gum, yogurts, ice cream, coffee creamers, salad dressings, and protein bars and shakes. They are also found in lower-calorie and sugar-free foods like energy bars, puddings, frostings, cakes, cookies, candies, and jams.

The most commonly used sugar alcohols include xylitol, maltitol, sorbitol, and erythritol. Erythritol is the most well-tolerated sugar alcohol and is commonly found in keto baked goods and drinks. Xylitol is also suitable for a ketogenic diet and is commonly found in chewing gum as it may improve oral health and prevent tooth decay.

Sugar alcohols are considered to be keto-friendly because they have a less significant effect on blood sugar levels than regular sugar. However, some sugar alcohols, like maltitol, may have a more noticeable impact on blood sugar and should be limited on a keto diet.
