Sugar Alcohols And Keto: Carb Management Tips

Sugar alcohols are popular substitutes for sugar in keto and low-carb products. But are they keto-friendly?

Sugar alcohols are a type of carbohydrate that tastes like sugar but is processed differently by the body. They are neither sugar nor alcohol but get their name from their chemical structure, which contains an -OH (alcohol) group. They are often used as sweeteners because they have a similar taste and mouthfeel to sugar but with fewer calories.

Sugar alcohols are only partially absorbed by the body and have a minimal impact on blood sugar and insulin levels, making them a popular choice for people on keto or low-carb diets. However, they can cause digestive issues such as bloating, diarrhoea, and flatulence if consumed in excess.

Not all sugar alcohols are equal when it comes to their impact on blood sugar and insulin levels. Erythritol, for example, has a glycemic index of 0 and is easily tolerated by the body, making it a good keto-friendly option. On the other hand, maltitol can cause a blood glucose response and should be limited on a keto diet.

So, while sugar alcohols can be a great way to enjoy sweet-tasting foods while on a keto diet, it's important to choose the right types and consume them in moderation to avoid any negative side effects.

Sugar alcohols are a hybrid of sugar and alcohol, but contain neither

Sugar alcohols are indeed a hybrid of sugar and alcohol—but contain neither. They are carbohydrates that act like sugar in terms of taste but are processed differently by the body. They are derived from fruits and vegetables, although most commercial sugar alcohols are synthetically produced. They are also known as polyols and occur naturally in certain fruits and vegetables, but some are man-made and added to processed foods.

Sugar alcohols are popular in sugar-free and keto products because they don't spike blood sugar levels as regular sugar does. They are also used in sugar-free chewing gum, medications, laxatives, and toothpaste. Sugar alcohols are usually less sweet than regular sugar, which can be a great way to wean yourself off highly sweet foods. They are also tooth-friendly, as they are not fermented by bacteria in the mouth, which increases acid and damages tooth enamel.

Sugar alcohols are not easily absorbed by the body, which means they are less calorie-dense than sugar. This makes them a great option for low-carb baking and cooking. However, this also means that consuming too much can cause digestive issues such as bloating, diarrhoea, flatulence, and stomach aches.

Some common sugar alcohols include erythritol, mannitol, sorbitol, xylitol, lactitol, isomalt, and maltitol. Erythritol is a great option for keto as it has a glycemic index value of zero and is almost as sweet as sugar.

When counting carbs for keto, it's important to note that sugar alcohols are still counted as total carbohydrates. However, since they are not fully digestible, most people subtract the grams of sugar alcohols entirely or deduct a certain percentage from the total carbohydrate count.

They are harder to absorb and digest, so are lower in calories

Sugar alcohols are harder to absorb and digest, so they are lower in calories. This is because they have a different chemical structure to regular sugar, meaning the body does not absorb them as efficiently. As a result, they contain fewer calories and don't have the same negative effects as regular sugar, such as raising blood sugar levels or contributing to tooth decay.

Sugar alcohols are often used as lower-calorie sweeteners in sugar-free products, such as chewing gum, candies, and baked goods. They provide a sweet taste without the negative side effects associated with regular sugar. However, it's important to note that sugar alcohols are not as sweet as regular sugar and may cause digestive issues if consumed in large amounts.

The body doesn't fully digest most sugar alcohols, so they pass through to the large intestine, where they are fermented by gut bacteria. This can lead to bloating, gas, and other gastrointestinal issues, especially in individuals with irritable bowel syndrome (IBS). It's recommended that moderate doses of 10-15 grams per day are usually tolerated, but sensitive individuals may need to avoid or reduce their intake of sugar alcohols to prevent these symptoms.

Sugar alcohols are considered low-digestible carbohydrates, meaning they are not completely absorbed by the small intestine. This makes them a good alternative for people with prediabetes, diabetes, or metabolic syndrome, as they have a minimal effect on blood sugar levels. Additionally, sugar alcohols don't contribute to tooth decay and may even help prevent it. Xylitol and erythritol, for example, are commonly used in toothpaste and sugar-free mints or gums to promote dental health.

Overall, sugar alcohols are a popular choice for people on keto or low-carb diets because they offer a way to enjoy sweets without wrecking their carb count. However, it's important to consume them in moderation and pay attention to how your body reacts, as they can cause digestive issues if overconsumed.

They are often combined with artificial sweeteners to improve taste

Sugar alcohols are often combined with artificial sweeteners to improve taste. While sugar alcohols are less sweet than regular sugar, they are a popular alternative for those on low-carb diets as they have a lower impact on blood sugar spikes.

Sugar alcohols are harder to absorb and digest, which makes them a great option for low-carb baking and cooking meals. However, they are often combined with artificial sweeteners to enhance their sweet taste.

For example, erythritol is a sugar alcohol that is 60-80% as sweet as sucrose. It is a near-zero-calorie natural sweetener commonly used in low-calorie foods. Erythritol is often combined with other sweeteners, such as xylitol, to balance out the flavour and improve the texture in keto treats.

Xylitol is another common sugar alcohol that is as sweet as regular sugar but has 40% fewer calories. It is often found in chewing gum, toothpaste, and mouthwash, as well as hard candy and gum drops.

By combining sugar alcohols with artificial sweeteners, manufacturers can create a sweet taste that is similar to regular sugar while still offering the benefits of a low-carb alternative. This makes these products appealing to those on keto or low-carb diets who are looking to reduce their sugar intake without sacrificing taste.

It is important to note that while sugar alcohols can be a great alternative to sugar, consuming too much can lead to digestive issues such as bloating, diarrhoea, and flatulence. Therefore, it is recommended to consume sugar alcohols in moderation and be mindful of the potential side effects.

They are only partially absorbed by the body, so can cause digestive issues

Sugar alcohols are only partially absorbed by the body, which can lead to digestive issues. This is because the part that isn't absorbed by the small intestine continues to the large intestine, where it may be fermented by bacteria, leading to digestive issues such as bloating, gas, stomach ache, and diarrhoea.

The extent of these side effects depends on the type of sugar alcohol and the amount consumed. For example, erythritol is well tolerated as it is mostly absorbed in the small intestine and isn't fermented by gut bacteria. On the other hand, maltitol, isomalt, and sorbitol are more likely to cause digestive issues.

Most people can tolerate up to 20-30 grams of sugar alcohols per day without experiencing any problems. However, those with digestive sensitivities or irritable bowel syndrome (IBS) may need to be more cautious and limit their intake to smaller amounts or avoid sugar alcohols altogether.

To minimise the risk of digestive issues, it's important to be mindful of the type of sugar alcohol and the amount consumed. Additionally, combining sugar alcohols with other sweeteners or low-calorie sweeteners can help round out their taste and reduce the amount needed.

Erythritol is a good keto-friendly option

Erythritol is a sugar alcohol, a type of carbohydrate that has a similar taste to sugar but is processed differently by the body. It is a good option for those on a keto diet as it has a glycemic index of 0, meaning it does not raise blood sugar levels. It also has a negligible impact on insulin levels. This makes it a popular choice for keto-friendly products and recipes.

Erythritol is often made by fermenting the glucose found in cornstarch. It has 70% of the sweetness of sugar but only 5% of the calories. It is also almost entirely excreted through urine, which is why it is non-glycemic and calorie-free.

Erythritol is a versatile sweetener that can be used in baking, cooking, and drinks. It tends to be better tolerated than other sugar alcohols, although some people may still experience gastrointestinal side effects such as bloating, gas, and diarrhea. It is also important to note that while erythritol is generally recognized as safe by the FDA, a recent study has linked it to higher risks of major heart events. As such, it is recommended to use it sparingly until further research is conducted.

Overall, erythritol is a good keto-friendly option for those looking to reduce their sugar intake while still enjoying sweet-tasting foods. However, as with all sugar alcohols, moderation is key to avoid potential digestive issues.
