Sugar Alcohols: How Many Are Keto-Friendly Daily?

Sugar alcohols are a type of carbohydrate with a chemical composition similar to sugar and alcohol. They are commonly used as sugar substitutes and are often found in products labelled as sugar-free. Sugar alcohols are popular among people on the keto diet as they are sweet-tasting but can claim to have no sugar added on the packaging.

Sugar alcohols are harder for the body to digest than standard sugar, and so they yield fewer calories and carbohydrates. They also have a less significant effect on blood sugar levels.

However, consuming too many sugar alcohols may cause digestive issues such as gas, cramping, and diarrhoea. The acceptable amount varies by individual sensitivity and body mass, but most people can avoid discomfort by consuming less than 15-30 grams of sugar alcohols per day.

Sugar alcohols are sweeteners that taste similar to sugar but have fewer calories and a less significant effect on blood sugar levels

Sugar alcohols are often used as sugar substitutes and are advertised as having 0 calories per gram. They are popular among people on the ketogenic diet as they are sweet-tasting but can be packaged as "no sugar added".

As the name suggests, sugar alcohols are sugar compounds with a chemical structure similar to glucose but with an attached hydroxyl group (-OH) or alcohol group. They are similar in structure to glucose but are digested differently, which is why they yield fewer calories and carbohydrates.

Types of Sugar Alcohols

Not all sugar alcohols are the same. The most common types include xylitol, maltitol, sorbitol, and erythritol. Mannitol and glycerol are also sugar alcohols.

Absorption, Digestion, and Side Effects

Sugar alcohols are partially digested in the small intestine. The remnants that are not digested are broken down by bacteria in the large intestine and passed through as stool.

The breakdown of sugar alcohols can lead to gastrointestinal disturbances as they draw water into the intestine, which can cause diarrhoea. Additionally, the breakdown by bacteria in the large intestine can lead to gas and other symptoms such as stomach cramps and bloating.

Erythritol is the most keto-friendly sugar alcohol. It is commonly found in keto-baked goods and drinks and does not impact blood glucose levels.

Xylitol is also keto-friendly and is often found in chewing gum as it may improve oral health and prevent tooth decay. However, it should be noted that xylitol is toxic to dogs and should be avoided if you have a pet.

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

Calculating Net Carbs

Net carbs are typically calculated as total carbohydrates minus fibre and the amount of sugar alcohol. However, some sugar alcohols, like maltitol and sorbitol, are digested and can spike blood glucose levels. Therefore, it is best to only subtract erythritol from the total carbs when calculating net carbs.

In some cases, xylitol can also be subtracted, but consumption should be monitored to avoid a glycemic response.

Sugar alcohols are commonly used in sugar-free products and can be found naturally in certain fruits and vegetables

Sugar alcohols are a type of carbohydrate with a chemical composition similar to sugar and ethanol. They are called sugar alcohols because they are sugar compounds with a chemical structure similar to glucose but with a hydroxyl group (-OH, or alcohol group) attached.

Sugar alcohols are often used as an alternative to table sugar (sucrose) because they are sweet-tasting but can be labelled as having no sugar. They are also used to add structure to baked goods.

The most common sugar alcohols include xylitol, maltitol, sorbitol, and erythritol. Mannitol and glycerol are also sugar alcohols.

Sugar alcohols are only partially digested and yield fewer calories and carbohydrates. They are harder for the body to digest, so they have a less dramatic effect on blood sugar levels. This means that they don't significantly interfere with fat burning, which makes them acceptable on low-carb diets like keto and Atkins.

However, consuming too many sugar alcohols may cause digestive issues like gas, cramping, and diarrhoea. This is because sugar alcohols draw water into the intestine and are broken down by bacteria in the large intestine. These side effects are most severe when consuming maltitol. Erythritol is the most well-tolerated sugar alcohol.

Sugar alcohols can be subtracted from total carbs when calculating net carbs, but it depends on the sweetener. Net carbs are typically calculated as total carbohydrates minus fibre and the amount of sugar alcohol. However, some sugar alcohols like maltitol and sorbitol are digested and can spike blood glucose levels, so it is best to only subtract erythritol from total carbs when calculating net carbs.

Erythritol is the most keto-friendly sugar alcohol as it has a glycemic index of 0 and is well-tolerated

Erythritol is a keto-friendly sugar alcohol. It has a glycemic index of 0, meaning it does not raise blood sugar levels and will not disrupt ketosis. Erythritol is also well-tolerated, with fewer gastrointestinal side effects than other sugar alcohols. It has a sweetness of around 60-80% of table sugar and contains very few calories. It can be used as a substitute for table sugar in beverages and some recipes, although its cooling effect on the tongue may make it unsuitable for baked goods.

Sugar alcohols are harder for the body to digest, which can lead to digestive issues such as gas, cramping and diarrhoea

Sugar alcohols are a type of carbohydrate that is hard for the body to digest. They are partially broken down in the small intestine, and the remnants that are not digested are passed to the large intestine, where they are broken down by bacteria. This process can cause a build-up of gas, leading to digestive issues such as cramping and diarrhoea.

The good news is that not all sugar alcohols are created equal. Some are better tolerated by the body than others and can be enjoyed in moderation as part of a keto diet. For example, erythritol is well-tolerated and has a minimal impact on blood glucose levels, making it a good choice for keto-friendly baked goods and drinks. Xylitol, commonly found in chewing gum, may also be consumed on a ketogenic diet, although it should be avoided if you have a dog as it is toxic to canines.

On the other hand, maltitol and sorbitol are two sugar alcohols that are known to cause digestive issues and should be avoided on a ketogenic diet. They are only partially digested and can cause a spike in blood glucose levels, which is not ideal when trying to maintain ketosis.

It's important to note that individual sensitivity to sugar alcohols can vary. While some people can consume larger amounts without issue, others may experience digestive problems when consuming even small quantities. It's always a good idea to start slowly and see how your body reacts before increasing your intake.

Sugar alcohols can be subtracted from total carbs when calculating net carbs, but this varies depending on the type of sugar alcohol

Sugar alcohols are often used as sweeteners in keto-friendly products. They are popular because they are harder for the body to break down and absorb compared to sugar, so they cause a much smaller rise in blood sugar levels. This means that they can be subtracted from the total number of carbs in a food item to give you a figure known as 'net carbs'.

However, this varies depending on the type of sugar alcohol. For example, erythritol is fully absorbed in the small intestine and then excreted without being metabolised, so it can be completely subtracted from the total carb count. On the other hand, sorbitol is only 25% absorbed in the small intestine, while the rest is fermented by bacteria, so only 75% of it can be subtracted from the total carb count.
