Maltitol And Keto: A Bad Combination?

Maltitol is a sugar alcohol commonly used as a sweetener in sugar-free and low-carb products. It is made from glucose and sorbitol and is about 70-90% as sweet as sugar. While it is often marketed as a keto-friendly alternative to sugar, there is significant debate within the keto community about its compatibility with a keto diet.

Maltitol increases blood glucose levels

Maltitol is a sugar alcohol, or polylol, that is commonly used as a sweetener in sugar-free and keto-friendly products. While it is true that maltitol has fewer calories than regular table sugar, it is still a carbohydrate and can affect your blood glucose levels.

Maltitol is made from glucose and sorbitol and is roughly 70-90% as sweet as sugar. It contains about 2.1 to 3 calories per gram, compared to table sugar, which has 4 calories per gram. This means that maltitol is not completely calorie-free, and consuming too much of it can affect your blood glucose levels.

When you consume maltitol, it is partially broken down into glucose and sorbitol in the intestines. The glucose is completely absorbed, while the sorbitol is only partially absorbed. This process of breaking down maltitol results in a slower rise in blood sugar and insulin levels compared to sucrose and glucose. However, it still causes an increase in blood glucose levels, which can be problematic for people on keto diets or those trying to manage their weight.

The glycemic index of a food is a measure of its effect on blood glucose levels. Maltitol syrup has a glycemic index of 52, while the powdered form has a glycemic index of 35. In comparison, white table sugar has a glycemic index of 65. This shows that maltitol can indeed increase blood glucose levels, although not as much as regular sugar.

It is important to note that the effect of maltitol on blood glucose levels also depends on the amount consumed and the individual's metabolism. Some people may be more sensitive to the effects of maltitol, while others may be able to tolerate higher amounts without experiencing significant changes in their blood glucose levels.

In conclusion, while maltitol may be a suitable alternative sweetener for some people, especially those with diabetes, it is important to recognize that it can increase blood glucose levels. Therefore, individuals on keto diets or those trying to manage their weight should be cautious about consuming maltitol and should always read labels to ensure they are making informed choices about their food selections.

Maltitol is a sugar alcohol

Sugar alcohols are carbohydrates that partially resemble sugar and alcohol but are not fully absorbed by the human body, making them low-calorie and low-carb. They are found naturally in some fruits and vegetables but are also commercially produced from starches and sugars. Maltitol, in particular, is derived from starch and is considered a carbohydrate. It has a glycemic index of 52, compared to sucrose (table sugar) which has a GI of 60. This means that it is partially broken down into glucose, elevating blood sugar levels and triggering an insulin response.

Maltitol is used as a sugar substitute because it shares many properties with sugar but has almost half the calories. It is also similar to sugar in taste, texture, and interaction with other ingredients. It is available in granular, powdered, and liquid syrup forms, with the liquid form being suitable for sweetening tea or coffee. The powdered and granular forms are not always straightforward substitutes for sugar in baking, so adjustments may be needed.

While maltitol can be a beneficial sugar substitute for some, it is important to be aware of potential side effects. Consuming large amounts of maltitol can cause gastrointestinal issues, including abdominal discomfort, bloating, gas, stomach pains, cramping, and diarrhea. The FDA has categorized maltitol as "generally recognized as safe," but has issued a warning about its laxative effects when ingested by adults at levels above 100 grams per day. To avoid these side effects, it is recommended to start with small amounts of maltitol and gradually increase as tolerated.

Maltitol is high in net carbs

Maltitol is a sugar alcohol, which is a type of carbohydrate that is neither sugar nor alcohol. It is made by reducing maltose and has a taste, texture, and interaction with other ingredients that are similar to sugar. It is often used as a sugar replacement because it causes a slower rise in blood sugar and insulin than d-glucose or sucrose.

Maltitol is commonly found in baked goods, candy, and other sweetened items that aim to reduce the total caloric and carbohydrate levels of certain sweet foods. It is also used in sugar-free and low-carb products such as candy and nutrition bars.

Because of its high glycemic index and the fact that it is high in net carbs, maltitol should be avoided on a keto diet. It is important to limit your net carb consumption to 20-30 grams per day to stay in ketosis. Instead of maltitol, you can use non-glycemic and non-caloric sweeteners such as stevia, monk fruit, and erythritol.

Maltitol is linked to an increased risk of chronic diseases

Maltitol is a sugar alcohol, or polylol, commonly used as a sweetener in sugar-free and low-calorie foods and drinks. It is often found in sugar-free chocolate, baked goods, candy, chewing gum, and ice cream. While maltitol is considered safe for human consumption by the FDA, it has been linked to an increased risk of chronic diseases, particularly gastrointestinal issues.

Maltitol is only partially digested and absorbed by the body. After consumption, it is broken down into sorbitol and glucose in the intestines. While glucose is completely absorbed, sorbitol is only partially absorbed. The remaining maltitol that is not broken down is then fermented by bacteria in the large intestine, which can cause gastrointestinal issues.

The most common side effects associated with consuming maltitol include gastrointestinal problems such as bloating, gas, stomach pains, cramping, and diarrhea. These side effects can occur even in small doses, and people with irritable bowel syndrome (IBS) may be more susceptible to experiencing these symptoms. Additionally, maltitol has a laxative effect when consumed in larger amounts, with the FDA requiring products containing over 50 grams of maltitol to carry a warning about potential laxative effects.

Furthermore, maltitol can affect blood glucose levels, which is a concern for people with diabetes. While it has a lower glycemic index than table sugar, it still elevates blood sugar and triggers an insulin response. This can be misleading for people following a keto diet or trying to manage their weight, as it may hinder their efforts to control blood sugar levels and maintain ketosis.

In conclusion, while maltitol is generally considered safe, it has been linked to an increased risk of gastrointestinal issues and can affect blood glucose levels. Therefore, it is important for individuals, especially those with IBS or diabetes, to be aware of the potential risks associated with consuming maltitol and to consume it in moderation to minimize the risk of adverse effects.

Maltitol has a laxative effect

Maltitol is a sugar alcohol or polylol that is commonly used as a sweetener in sugar-free foods. It is roughly 70-90% as sweet as sugar and contains about 2.1 calories per gram, as compared to table sugar, which has 4 calories per gram. It is not metabolised by oral bacteria and so does not promote tooth decay.

Maltitol is a laxative and can cause GI issues. It draws water from the GI tract, which can cause bloating, gas, stomach pains, cramping, and diarrhoea. It is recommended that a daily consumption of more than 90g of maltitol may have a laxative effect on the human body. However, this amount is very high and most people will consume much lower quantities.

Maltitol is broken down in the intestines back into sorbitol and glucose. The glucose is completely absorbed, whereas the sorbitol is only partially absorbed. Any remaining maltitol is fermented by bacteria in the large intestine.

Maltitol is not keto-friendly as it increases blood sugar levels. A test showed that after eating 50g of maltitol syrup, blood sugar levels went up by 40 points in just 30 minutes. This is a major drawback for those on a keto, low-carb, or diabetic-friendly diet.
