Demystifying Artificial Sweeteners: The Chemical and Brand Names
For many years, consumers have turned to non-nutritive sweeteners as a way to reduce calorie intake and manage blood sugar levels. The world of low- and zero-calorie sweeteners is broad, encompassing many chemical compounds, each with unique properties. Breaking down these alternatives can help clarify their differences and how they appear on food labels.
Artificial Sweeteners
Artificial sweeteners are synthesized compounds that can be many times sweeter than regular table sugar (sucrose). Because they are so intensely sweet, only a tiny amount is needed, meaning their caloric contribution is often negligible. Several of these have been approved by regulatory bodies, including the U.S. Food and Drug Administration (FDA), for use in various foods and beverages.
-
Acesulfame Potassium (Ace-K): This is a calorie-free sweetener that is approximately 200 times sweeter than sugar. It is often blended with other sweeteners to mask its slight aftertaste. Brand names include Sunett® and Sweet One®. It is heat-stable and can be used in baking.
-
Advantame: One of the most potent sweeteners on the market, advantame is about 20,000 times sweeter than sugar. Approved by the FDA in 2014, it is a derivative of aspartame but is heat-stable and can be used by people with phenylketonuria (PKU).
-
Aspartame: Composed of two amino acids, aspartic acid and phenylalanine, aspartame is roughly 200 times sweeter than sugar. It is not heat-stable and is commonly used in products that don't require cooking, such as diet sodas, sugar-free gum, and tabletop sweeteners. Brand names include NutraSweet®, Equal®, and Sugar Twin®.
-
Neotame: This sweetener is structurally similar to aspartame but is even more potent, ranging from 7,000 to 13,000 times sweeter than sugar. Sold under the brand name Newtame®, it is heat-stable and can be used in baking.
-
Saccharin: Discovered in 1879, saccharin is one of the oldest artificial sweeteners. It is 200 to 700 times sweeter than sugar and has no calories. Despite past controversies, it has been deemed safe for human consumption by regulatory bodies. Common brand names include Sweet'N Low®, Sweet Twin®, and Necta Sweet®.
-
Sucralose: This chlorinated sugar is approximately 600 times sweeter than sucrose. It is heat-stable, making it suitable for baking and cooking. It is widely recognized by the brand name Splenda®.
Natural Non-Nutritive Sweeteners
These sweeteners are derived from natural sources, such as plants, but are processed to concentrate their sweet-tasting compounds. They are calorie-free and do not typically impact blood glucose levels.
-
Stevia (Steviol Glycosides): Extracted from the leaves of the Stevia rebaudiana plant, stevia extracts are 200 to 400 times sweeter than sugar. Highly purified extracts are generally recognized as safe (GRAS) by the FDA. Brand names include Truvia®, PureVia®, and Stevia In The Raw®.
-
Monk Fruit (Luo Han Guo): This sweetener is extracted from the fruit of the Siraitia grosvenorii plant, native to southern China. Its sweetness comes from compounds called mogrosides. Monk fruit is 100 to 250 times sweeter than sugar and is also recognized as GRAS by the FDA. Brand names include Monk Fruit In The Raw® and Lakanto®.
Sugar Alcohols (Polyols)
Sugar alcohols are carbohydrates that are used as sweeteners and bulking agents. They are found naturally in some fruits and vegetables but are also commercially manufactured. They are less sweet and have fewer calories than sugar, and they do not cause a sudden spike in blood glucose.
-
Erythritol: Naturally found in some fruits, this sugar alcohol has zero calories and is about 70% as sweet as sugar. It is often used as a bulking agent in other sweetener blends, such as some stevia products.
-
Xylitol: Found in many fruits and vegetables, xylitol is as sweet as sugar but with fewer calories. It is known for not promoting tooth decay.
-
Sorbitol: This sugar alcohol is roughly 60% as sweet as sugar and is often used in sugar-free candies and gums.
Comparison of Common Sugar Substitutes
| Feature | Aspartame (Equal) | Sucralose (Splenda) | Stevia (Truvia, PureVia) | Monk Fruit (Luo Han Guo) | Erythritol | Saccharin (Sweet'N Low) |
|---|---|---|---|---|---|---|
| Origin | Chemical Synthesis (Amino Acids) | Chemical Synthesis (Chlorinated Sugar) | Plant Extract | Plant Extract (Fruit) | Sugar Alcohol (Fermentation) | Chemical Synthesis |
| Sweetness | ~200x sweeter than sugar | ~600x sweeter than sugar | ~200-400x sweeter than sugar | ~100-250x sweeter than sugar | ~70% as sweet as sugar | ~200-700x sweeter than sugar |
| Calories | Minor calories per serving (due to bulking agents) | Minor calories per serving (due to bulking agents) | Zero | Zero | Zero | Zero |
| Heat Stable? | No (loses sweetness when heated) | Yes | Yes | Yes | Yes | Yes |
| Common Uses | Diet sodas, chewing gum, tabletop sweetener | Baking, beverages, frozen desserts | Beverages, baked goods, tabletop sweetener | Beverages, dairy products, baked goods | Chewing gum, candies, bulking agent | Canned fruit, drinks, tabletop sweetener |
Understanding the Labels
Identifying which sugar substitute is in a product requires careful reading of the ingredients list. Look for both the chemical name and the brand name, as manufacturers may use either one. For example, a product may list "sucralose" or "Splenda" as an ingredient. Natural sweeteners like stevia and monk fruit are increasingly popular and often highlight their plant-based origin on the packaging. Sugar alcohols are also listed on the nutrition facts label, often under a separate "sugar alcohols" line. Blended sweeteners, which combine several types for an optimized taste, are also common.
Navigating Safety and Dietary Concerns
While approved sugar substitutes are generally considered safe for healthy individuals when consumed in moderation, they are not without potential health considerations.
-
Digestive Issues: Some sugar alcohols, like xylitol and sorbitol, are not fully absorbed by the body. In sufficient amounts, this can lead to digestive discomfort such as bloating, gas, or a laxative effect.
-
Phenylketonuria (PKU): Individuals with this rare genetic disorder cannot metabolize the amino acid phenylalanine. Since aspartame contains phenylalanine, those with PKU should avoid it.
-
Microbiome Impact: Research is ongoing regarding how artificial sweeteners might affect the gut microbiome. Some studies suggest potential disruptions, while others find no significant short-term effects.
-
Weight Management: The long-term effectiveness of non-nutritive sweeteners for weight management is debated. While they provide low or no calories, some studies have shown mixed results regarding their impact on weight, with some linking them to potential weight gain over time.
Note: Always consult a healthcare provider or a registered dietitian if you have concerns about incorporating sugar substitutes into your diet, especially if you have pre-existing health conditions like diabetes.
Conclusion: Making Informed Choices
In conclusion, the world of "fake sugar" is much more diverse than a single name suggests. It includes a variety of chemical and natural compounds, each offering a different sweetness profile and suitability for various applications. From the heat-stable sucralose to the plant-derived stevia and the sugar alcohol erythritol, consumers have many options. Knowing the different names for these sugar substitutes, both their chemical names and brand names, empowers individuals to read labels accurately and make informed dietary decisions that align with their health goals. While safety concerns exist and research continues, major health organizations, including the FDA, have approved their use within specified acceptable daily intake limits for healthy populations.
