Sugar Substitutes: Other Sweetener Choices

FDA also has approved two other artificial sweeteners, acesulfame potassium and sucralose, both of which are available in products such as fruit drinks and gelatin desserts.

Acesulfame Potassium: First approved in 1988 as a tabletop sweetener, acesulfame potassium, also called Sunett, is now approved for products such as baked goods, frozen desserts, candies, and, most recently, beverages. More than 90 studies verify the sweetener's safety.

About 200 times sweeter than sugar and calorie free, acesulfame potassium often is combined with other sweeteners. One major beverage maker mixes acesulfame potassium with aspartame to sweeten one of its diet sodas. Worldwide, the sweetener is used in more than 4,000 products, according to its manufacturer, Nutrinova. Acesulfame potassium has excellent shelf life and does not break down when cooked or baked.

Sucralose: Also known by its trade name, Splenda, sucralose is 600 times sweeter than sugar. After reviewing more than 110 animal and human safety studies conducted over 20 years, FDA approved it in 1998 as a tabletop sweetener and for use in products such as baked goods, nonalcoholic beverages, chewing gum, frozen dairy desserts, fruit juices, and gelatins. Earlier this year, FDA amended its regulation to allow sucralose as a general-purpose sweetener for all foods.

Sucralose tastes like sugar because it is made from table sugar. But it cannot be digested, so it adds no calories to food. Because sucralose is so much sweeter than sugar, it is bulked up with maltodextrin, a starchy powder, so it will measure more like sugar. It has good shelf life and doesn't degrade when exposed to heat. Numerous studies have shown that sucralose does not affect blood glucose levels, making it an option for diabetics.

Sugar Alcohols: Though not technically considered artificial sweeteners, sugar alcohols are slightly lower in calories than sugar and do not promote tooth decay or cause a sudden increase in blood glucose. They include sorbitol, xylitol, lactitol, mannitol, and maltitol and are used mainly to sweeten sugar-free candies, cookies, and chewing gums. FDA classifies some of these sweeteners as "generally recognized as safe" and others as approved food additives.

Other "natural sweeteners" are available, but these are variations of table sugar and contain about the same amount of calories. These products include honey, molasses, evaporated cane juice, rice syrup, barley malt, and fructose.

Another product, stevia, is derived from a South American shrub. Though it can impart a sweet taste to foods, it cannot be sold as a sweetener because FDA considers it an unapproved food additive. "The safety of stevia has been questioned by published studies," says Martha Peiperl, a consumer safety officer in FDA's Office of Premarket Approval. "And no one has ever provided FDA with adequate evidence that the substance is safe." Under provisions of 1994 legislation, however, stevia can be sold as a "dietary supplement," though it cannot be promoted as a sweetener.

Three other sugar sweeteners are currently under FDA review. One of them, cyclamate, was marketed in the 1960s, but FDA banned it in 1970 after evidence emerged linking it to bladder cancer. Subsequent studies have failed to verify that link, so FDA is considering a petition to reapprove cyclamate. The other sweeteners under review are neotame and alitame.

Though sugar substitutes have a long history of controversy, the Calorie Control Council says Americans are continually searching for good-tasting, low-calorie products as part of a healthy lifestyle. Market surveys show that calorie-conscious consumers want more low-calorie foods and beverages. And though artificially sweetened products are not magic foods that will melt pounds away, they can be, experts say, a helpful part of an overall weight control program that includes exercise and other dietary factors.
