When navigating the world of sweeteners, it's easy to get lost in general terms like 'natural' or 'synthetic.' However, a deeper understanding reveals nuances. While 'natural' might refer to common sugars such as table sugar, brown sugar, honey, or maple syrup, the term 'synthetic' often encompasses artificial sweeteners. Adding another layer of complexity, sugar alcohols also serve as popular sugar substitutes.

For those looking to reduce sugar intake and contemplating between sugar alcohols and artificial sweeteners, both can play a beneficial role. Hannah Thompson, RDN, LD, CPT, notes that despite their similar applications, these sweeteners differ in their chemical makeup and sweetness intensity. They are widely utilized to impart sweetness and enhance flavors without contributing excess calories or carbohydrates.

Despite their common goal of sweetening, these sugar alternatives exhibit distinct characteristics. Below, we'll dissect the disparities between sugar alcohols and artificial sweeteners, and ascertain if one offers a healthier option than the other.

Sugar Alcohols: A Closer Look

Sugar alcohols are carbohydrate compounds sharing structural similarities with both sugars and traditional alcohol (though they do not cause intoxication). Mary Ellen Phipps, M.P.H., RDN, LD, explains that sugar alcohols are categorized as nutritive sweeteners because they do provide some caloric value. On average, they contribute approximately 2 calories per gram, half the amount found in table sugar.

Their sweetness varies from half to equal that of table sugar, meaning larger quantities may be needed to achieve the desired sweetness. Although naturally occurring in small amounts in some fruits and vegetables, they are also produced industrially. Due to their ability to provide significant sweetness with minimal calories, they are frequently used to replace sugar in products like chewing gum, candies, desserts, and baked goods.

Such products are often labeled as 'diet,' 'no-sugar-added,' or 'sugar-free.' The amount of sugar alcohols present in a product can be found listed under carbohydrates on its Nutrition Facts panel.

Commonly used sugar alcohols in food products include:

• Erythritol
• Hydrogenated starch hydrolysates (HSH)
• Isomalt
• Lactitol
• Maltitol
• Mannitol
• Sorbitol
• Xylitol

Artificial Sweeteners: An Overview

In contrast to sugar alcohols, artificial sweeteners, also known as nonnutritive sweeteners, are typically calorie and carbohydrate-free, with aspartame being a notable exception, containing 4 calories per gram. However, these sweeteners are considerably more potent than table sugar, ranging from 200 to an astounding 20,000 times sweeter. Consequently, only minuscule amounts are required to achieve the same level of sweetness, rendering the caloric contribution of aspartame negligible in practice.

Artificial sweeteners are prevalent in foods and beverages marketed as 'sugar-free' or 'diet,' such as desserts, soft drinks, candies, yogurts, and jellies.

Some well-known nonnutritive sweeteners and their commercial names include:

• Acesulfame-K (Sunett and Sweet One)
• Advantame (Advantame)
• Aspartame (Nutrasweet, Equal and Sugar Twin)
• Saccharin (Sweet’N Low)
• Sucralose (Splenda)

Sugar Alcohols vs. Artificial Sweeteners: Making the Choice

When deciding between sugar alcohols and artificial sweeteners, or products containing them, personal health requirements are paramount. There isn't a universally 'better' option, as the ideal choice varies from person to person.

Key considerations include:

• Blood Sugar Regulation: For managing blood sugar levels, the type of sweetener is significant. Thompson states that nonnutritive sweeteners generally do not elevate blood sugar as much as table sugar or other carbohydrate-containing sweeteners, making them suitable for individuals with diabetes or those monitoring blood glucose. However, for those with diabetes, understanding the sugar alcohol content in products is still important, as they can cause some blood sugar elevation, and different sugar alcohols may have varying effects.
• Potential Side Effects: Phipps points out that common side effects of sugar alcohols, particularly mannitol and sorbitol, include bloating, loose stools, and gas. This often leads to gastrointestinal distress warnings on 'sugar-free' or keto product labels. Thompson also mentions occasional reports of headaches associated with nonnutritive sweeteners, though research suggests these are rare. If such symptoms occur, avoiding these sweeteners might be advisable.
• Individual Responses: Phipps emphasizes that sugar substitutes, both nutritive and nonnutritive, can be beneficial for many, but some individuals may choose to avoid them for various reasons. It's crucial to observe how your body reacts to foods containing these ingredients. For example, if erythritol in ice cream causes bloating or stomach cramps, opting for a brand with a different sweetener could be a solution.
• Overall Dietary Habits: The impact of a single food item, regardless of its sweetener—be it real sugar, artificial sweeteners, or sugar alcohols—is less critical than one's overall dietary pattern. Thompson highlights that comprehensive dietary habits are far more important than debating between these sweeteners. Furthermore, the presence of a sugar substitute does not inherently make a food more or less nutritious. While they can facilitate enjoying treats like ice cream or coffee drinks when managing sugar or calorie intake, moderation remains key.

Sugar alcohols and artificial sweeteners are viable sugar alternatives that impart sweetness with minimal or no caloric impact. They differ in their sweetness intensity, as well as their carbohydrate and calorie contributions. While both are considered safe for consumption, some individuals may experience gastrointestinal discomfort from sugar alcohols. This doesn't necessitate complete avoidance, but rather suggests finding what works best for your body. These substitutes can be valuable tools for reducing added sugars and calories, yet they don't automatically confer health benefits to foods. Therefore, view them as a means to occasionally indulge in sweet treats, as part of a balanced and comprehensive eating strategy.
