Keto Sweeteners: Sorbitol And Sucralose Explained

Sorbitol is a sugar alcohol that is naturally found in fruits but is mostly manufactured from corn syrup. It can act as a laxative and is about 60% as sweet as table sugar. It has been known to cause gastrointestinal distress and is not recommended for those with irritable bowel syndrome (IBS). Sucralose, on the other hand, is an artificial sweetener that is not metabolized by the body and is popular because it lacks the bitter taste found in many other artificial sweeteners. It is 600 times sweeter than regular sugar and has no impact on glucose. However, Splenda, a popular sucralose-based sweetener, contains maltodextrin and dextrose, two carbs that supply calories and carbs. Sucralose may not be suitable for baking as it could produce harmful compounds when exposed to high temperatures.

Sorbitol is a sugar alcohol that is 60% as sweet as sugar

Sorbitol is a sugar alcohol that is about 60% as sweet as sugar. It is a type of carbohydrate called a polyol. It is found naturally in some fruits, including apples, apricots, dates, berries, peaches, plums, and figs. It is also commercially manufactured from corn syrup or glucose and used as a sugar substitute in packaged foods, beverages, and medications.

Sorbitol has about two-thirds of the calories of table sugar and provides about 60% of the sweetness. It is often used in foods and beverages instead of traditional sugar to reduce their calorie content. It also has very little effect on blood sugar levels when eaten, which is why it is commonly added to foods marketed to people with diabetes.

In addition to its use as a sweetener, sorbitol is also used as a laxative to treat constipation. It works by drawing water into the large intestine, stimulating bowel movements. It can be purchased over the counter at most grocery and drug stores without a prescription.

While sorbitol is generally considered safe, consuming large amounts can cause side effects such as bloating, abdominal cramping, nausea, and diarrhea. These side effects are more likely with doses of 10 grams or more per day. It should also not be taken with calcium or sodium polystyrene sulfonate, as this can lead to intestinal tissue death.

Sucralose is an artificial sweetener that is calorie-free

Sucralose is made through a chemical process that begins with regular table sugar (sucrose). Three select hydroxyl groups on the sucrose molecule are replaced with three chlorine atoms. This structure prevents enzymes in the digestive tract from breaking it down, which is why it is not metabolized and passes through the body undigested.

Most consumed sucralose is not absorbed by the body and is excreted unchanged in feces. Of the small amount that is absorbed, none is broken down for energy, so sucralose does not provide any calories. All absorbed sucralose is quickly excreted in the urine.

Sucralose is generally considered safe and has been approved by the U.S. Food and Drug Administration (FDA) as a general-purpose sweetener. It can be used as an ingredient in any type of food or beverage, including baked goods and frozen desserts. However, it may not be a suitable substitute for sugar in recipes that require baking, as some studies have found that sucralose could produce harmful compounds when exposed to high temperatures.

While sucralose is touted as a way to enjoy sweet-tasting foods and beverages with fewer calories, its impact on weight loss is debated. Some studies suggest that it may help with weight loss or weight maintenance, while others indicate that it may stimulate appetite and lead to increased calorie intake.

In terms of gut health, human studies on short-term sucralose consumption have not shown any significant effects on the gut microbiome. However, long-term animal studies have found that it could disrupt the balance of the gut microbiome and increase inflammation. More research is needed to understand how sucralose affects gut health in humans.

Overall, sucralose is a popular artificial sweetener that can be used to reduce added sugar intake. While it is generally considered safe, there are some questions about its long-term health effects, especially regarding weight, gut health, and potential breakdown into harmful compounds when exposed to high temperatures.

Sucralose may not be suitable for baking

Sucralose is an artificial sweetener that is generally considered safe when consumed in moderation. However, its long-term effects are still unclear, and some studies have associated it with adverse health issues. Sucralose is calorie-free, and Splenda, the most popular sucralose-based product, is widely used in cooking and baking.

While sucralose is often deemed suitable for baking, recent studies have questioned its stability at high temperatures. Sucralose starts to break down and interact with other ingredients at high temperatures, potentially generating harmful substances called chloropropanols, which may increase cancer risk.

For instance, a 2010 study found that heating sucralose with glycerol, a compound found in fat molecules, produced chloropropanols. Conversely, a more recent study funded by the manufacturers of Splenda contradicted these findings, concluding that sucralose does not form these compounds when heated and is safe for cooking and baking.

Given the conflicting evidence, some people may prefer to use alternative sweeteners when baking at temperatures above 350°F (175°C) until further research clarifies the safety of sucralose at high temperatures.

Sucralose may cause harmful compounds when exposed to high temperatures

Sucralose is an artificial sweetener that is widely used as a non-caloric sweetener. It is popular because, unlike many other artificial sweeteners, it lacks a bitter aftertaste. Sucralose is not metabolised by the body, meaning it passes through undigested and does not contribute to calorie intake.

However, concerns have been raised about the stability of sucralose at high temperatures. Several studies have indicated that sucralose decomposes at high temperatures, such as those reached during cooking and baking. This decomposition is associated with the formation of potentially toxic chlorinated compounds, including chloropropanols, polychlorinated dibenzo-p-dioxins (PCDD), dibenzofurans (PCDF), and dioxins. These compounds have the potential to be harmful to health, with some displaying carcinogenic properties.

As a result of these findings, the German Federal Institute for Risk Assessment (BfR) recommends that foods containing sucralose are not heated to temperatures that occur during baking, deep-frying, and roasting. Alternatively, they suggest adding sucralose only after heating. This advice applies to both consumers and commercial food manufacturers.

While the potential health risks are still being assessed, it is clear that sucralose can degrade at high temperatures, leading to the generation of potentially harmful compounds. Therefore, it is advisable to follow the BfR's recommendations when using sucralose in cooking and baking.

Sucralose may or may not cause a rise in blood sugar

Sucralose is an artificial sweetener that is calorie-free and often used in place of sugar. It is sweeter than sugar, so only a small amount is needed to achieve a sweet taste. Sucralose has zero calories and can help with weight loss, making it a popular choice for people trying to manage their calorie intake or dieting. However, it may affect gut health and has the potential to cause digestive issues.

There is some debate about the effects of sucralose on blood sugar levels. On the one hand, artificial sweeteners like sucralose are marketed as sugar substitutes that do not raise blood sugar levels, which can make them a safer choice for people with diabetes. Some studies have found that sucralose has little to no effect on blood sugar levels in individuals of average weight who regularly consume it.

On the other hand, more recent research suggests that sucralose can cause blood sugar levels to spike in other populations, such as those with severe obesity who are new to using artificial sweeteners. A small study found that sucralose elevated blood sugar levels by 14% and insulin levels by 20% in 17 people with severe obesity who didn't regularly consume artificial sweeteners. These results indicate that sucralose may affect blood sugar levels in new users but have little effect on regular consumers.

For individuals with diabetes who do not produce insulin or respond properly to the hormone, a spike in blood sugar levels could lead to serious health problems. Therefore, it is recommended that people with diabetes limit their intake of sucralose and consult their doctor before adding it to their diet.

In conclusion, while sucralose is generally considered a safe alternative to sugar, there is some evidence that it may cause a rise in blood sugar levels, especially in new users or those with severe obesity. More research is needed to fully understand the link between sucralose and blood sugar levels, and individuals should consult their doctor to determine if sucralose is a suitable sweetener for their specific situation.
