Sugar substitutes are chemical or plant-based substances used to sweeten or enhance the flavor of foods and drinks. You may have heard them called “artificial sweeteners” or “non-caloric sweeteners.” They can be used as a tabletop sweetener (for example, to sweeten a glass of iced tea) and/or as an ingredient in processed foods and drinks.
Most sugar substitutes are many times sweeter than sugar. It takes a smaller amount of these sugar substitutes to provide the same level of sweetness. Some sugar substitutes are low in calories. Others have no calories.
Sugar substitutes are regulated as food additives by the U.S. Food and Drug Administration (FDA). This means that the FDA reviews scientific evidence to be sure that a sugar substitute is safe before it can be used in foods and drinks.
Path to improved health
Sugar substitutes provide sweetness and enhance the flavor of food without adding the calories of sugar. Unlike sugar, they do not contribute to tooth decay. Most of them do not raise blood sugar levels. This may be helpful if you have diabetes and have to be careful about how much sugar you consume.
Sugar substitutes may also be helpful if you are trying to control the amount of calories you consume. They are found in most of the “light,” “reduced calorie,” and “sugar-free” foods and drinks available today. Although sugar substitutes have fewer calories than sugar, it’s best to limit them and focus on healthy food choices. Fruits, vegetables, lean meats, and whole grains are the best sources of nutrition for your body.
How can I tell if a food or drink contains a sugar substitute?
Sugar substitutes are used in many processed foods and drinks, including baked goods, soft drinks, powdered drink mixes, candy, puddings, canned foods, jellies, and dairy products. Check the ingredient list on the nutrition facts label for the names of the sugar substitutes listed above. This list gives ingredients in descending order by weight. Unless you add a sugar substitute yourself, it is often hard to know exactly how much a food or drink contains.
What sugar substitutes/artificial sweeteners are approved by the FDA?
The following sugar substitutes are FDA approved as food additives in the United States:
- Acesulfame K (brand names: Sunett and Sweet One)
- Aspartame (two brand names: Equal and Nutrasweet)
- Neotame (brand name: Newtame)
- Saccharin (two brand names: Sweet ‘N Low and Sweet Twin)
- Sucralose (brand name: Splenda)
According to the FDA, some sugar substitutes are “generally recognized as safe” (GRAS). This means they do not require FDA approval because qualified experts agree the scientific evidence shows these products are safe for use in foods and drinks. Sugar substitutes in this category include highly purified stevia extracts called “steviol glycosides” (two brand names: Pure Via and Truvia) and monk fruit extracts (two brand names: Monk Fruit in the Raw and PureLo).
Sugar alcohols are another class of sweeteners that can be used as sugar substitutes. Examples include mannitol, sorbitol, and xylitol. The FDA has determined that sugar alcohols are generally recognized as safe for use in foods and drinks.
Aspartame is a common low-calorie sugar substitute. It is a combination of 2 amino acids: aspartic acid and phenylalanine. It is about 200 times sweeter than sugar. It can be found in thousands of processed foods and drinks. Products that contain aspartame include yogurt, frozen desserts, pudding, dry dessert mixes, chewing gum, and soft drinks.
It is used as a tabletop sweetener. It can also be found in some medicines (for example, cough drops) and vitamins. Aspartame should not be used as a substitute for sugar when you are baking. It loses its sweet taste when it is heated.
Is aspartame safe?
Aspartame is one of the most researched sugar substitutes available in the United States. More than 100 studies have examined its safety. It has been approved by the FDA as a food additive since 1981.
People who have a rare condition called phenylketonuria (PKU) should not consume aspartame. This is because their bodies are unable to metabolize (process) phenylalanine, which is one of the amino acids in aspartame.
According to the National Cancer Institute, there is no evidence that aspartame and other sugar substitutes approved for use in the United States cause cancer or other serious health problems. Medical research studies have shown that these sweeteners are safe for most people when used in moderation.
Acesulfame K is a no-calorie sugar substitute that is 200 times sweeter than sugar. It is also known as acesulfame potassium or Ace-K. It is often used in combination with other sweeteners.
Acesulfame K can be found in a variety of processed foods and drinks, including baked goods, candy, frozen desserts, and soft drinks. It can also be used as a tabletop sweetener. It is used in some medicines and in oral hygiene products (for example, toothpaste and mouthwash).
It can be used in cooking and baking because it does not lose its sweet taste at high temperatures. For best results, follow the package instructions for using it in your recipes.
Is acesulfame K safe?
More than 90 studies have examined the safety of acesulfame K. It has been approved by the FDA as a food additive since 1988. According to the National Cancer Institute, there is no evidence that acesulfame K and other sugar substitutes approved for use in the United States cause cancer or other serious health problems.
Saccharin is a low-calorie sugar substitute that was first discovered in 1879. It is 200 to 700 times sweeter than sugar, depending on how it is used. Some people may notice an aftertaste when they consume saccharin. This is often eliminated in processed foods by combining saccharin with another sugar substitute.
Saccharin is found in many processed foods and drinks, including chewing gum, canned fruit, baked goods, and soft drinks. It is also used as a tabletop sweetener. It is used in some medicines and vitamins.
Saccharin can be used as a substitute for sugar when you are baking. For best results, follow the package instructions for using it in your recipes.
Is saccharin safe?
Saccharin is approved by the FDA as a food additive. You might remember that saccharin used to carry a warning label that said it was known to cause cancer in laboratory animals. However, there has been extensive research on the safety of this sugar substitute. In 2000, the U.S. government removed the requirement for a warning label on foods and drinks made with saccharin.
Stevia is a plant-based sugar substitute that has no calories. The term “stevia” refers to Stevia rebaudiana, which is a South American plant. Only certain parts of the plant are sweet. Highly purified extracts from the leaves of the plant are called “steviol glycosides.” They are 200 to 400 times sweeter than sugar.
The term “stevia” can refer to the whole Stevia rebaudiana plant. However, in this article, “stevia” refers to the sugar substitute made from steviol glycosides. That is how the term is commonly used.
Stevia is found in many processed foods and drinks, such as desserts, chewing gum, baked goods, candy, and yogurt. It is also used as a tabletop sweetener. Stevia can be used as a substitute for sugar when you are baking. For best results, follow the package instructions for using it in your recipes.
Is stevia safe?
According to the FDA, steviol glycosides are “generally recognized as safe” (GRAS). This means that qualified experts agree the available scientific evidence about this sugar substitute shows it is safe for use in foods and drinks.
Sucralose is a no-calorie sugar substitute. It is about 600 times sweeter than sugar.
It is used in thousands of processed foods and drinks. Some examples include soft drinks, juices, sauces, syrups, candy, desserts, baked goods, and canned fruits. It is used in medicines, nutritional supplements, and vitamins. It is also used as a tabletop sweetener.
Sucralose can be used in baking because it does not lose its sweet taste at high temperatures. For best results, follow the package instructions for using it in your recipes.
Is sucralose safe?
More than 110 studies have examined the safety of sucralose. It has been approved by the FDA as a food additive since 1998.
According to the National Cancer Institute, there is no evidence that sucralose and other sugar substitutes approved for use in the United States cause cancer or other serious health problems.
Despite their name, sugar alcohols aren’t sugar, and they aren’t alcohol. They are carbohydrates that occur naturally in certain fruits and can also be manufactured. They get their name because they have a chemical structure similar to sugar and to alcohol. Sugar alcohols are also called “polyols.”
What products contain sugar alcohols?
Sugar alcohols are found in many processed foods, including hard candies, ice cream, puddings, baked goods, and chocolate. They can also be found in chewing gum, toothpaste, and mouthwash. They may be used in combination with another sugar substitute.
The most common sugar alcohols found in foods include:
- Erythritol – 0.2 calories per gram and 60% to 80% as sweet as sugar
- Isomalt– 2 calories per gram and 45% to 65% as sweet as sugar
- Lactitol – 2 calories per gram and 30% to 40% as sweet at sugar
- Maltitol – 2.1 calories per gram and 90% as sweet as sugar
- Mannitol – 1.6 calories per gram and 50% to 70% as sweet as sugar
- Sorbitol – 2.6 calories per gram and 50% to 70% as sweet as sugar
- Xylitol – 2.4 calories per gram and the same sweetness as sugar
By comparison, there are 4 calories per gram of sugar.
How do I find sugar alcohols on a nutrition facts label?
If a food is labeled as “sugar free,” the amount of sugar alcohol (in grams) must be listed. If the food contains only 1 sugar alcohol, the name of that specific sugar alcohol is listed. Sugar alcohols are easy to spot on the label because most of them end in “tol.” If the food contains more than 1 sugar alcohol, the term “sugar alcohols” is listed.
How do sugar alcohols affect blood sugar levels?
Your body doesn’t completely absorb sugar alcohols, so they don’t affect your blood sugar levels as much as sugar and other carbohydrates do.
If you have diabetes, it is important to consider sugar alcohols when you are managing your blood sugar level. Check the nutrition facts label on a processed food to find the amount of sugar alcohol per serving (listed in grams). If a food has fewer than 5 grams of sugar alcohol per serving, it will likely have a very small effect on your blood sugar level.
Are sugar alcohols safe?
According to the FDA, sugar alcohols are “generally recognized as safe” (GRAS). This means that qualified experts agree the available scientific evidence shows they are safe for use in foods and drinks. However, you should consume them in moderation. Because sugar alcohols aren’t completely absorbed by your body, eating large amounts can lead to bloating and diarrhea.
Things to consider
Over the years, there has been much research done concerning the safety of sugar substitutes. The findings of this research support the conclusion that FDA-approved sugar substitutes are safe to use in moderation. Also, GRAS sugar substitutes (stevia extracts, monk fruit extracts, and sugar alcohols) are considered safe.
While they are considered safe, sugar substitutes can cause diarrhea. This can happen when you consume large amounts of a product such as sugar-free candy.
When to see a doctor
Health experts have debated for years the use of sugar substitutes. Some would say that sugar substitutes are still controversial. However, the scientific community and FDA agree that they are safe to use, especially in moderation. If you have concerns, you should talk to your doctor about how or when to include sugar substitutes as part of a healthy diet.
