The Truth on Artificial Sweeteners
Sweetness and Light
No getting around it, we Americans have a sweet tooth. Most of us eat the equivalent of 20 teaspoons of sugar a day. True, you're probably not sucking on sugar cubes throughout the day, but you are probably downing more than your fair share of sugary cereals, snacks, sodas, ice cream .. and the list goes on and on.
For the average person, there's nothing wrong with sugar per se, unless all the sweet foods in your daily diet are keeping you from eating and drinking the nutritious foods you need. But for people who are trying to lose weight, or have to watch their blood sugar because of diabetes, too much sugar can be a problem. That's where artificial sweeteners can come in handy. These low-calorie sweeteners, reports the International Food Information Council, are safe to use, provide sweetness without calories, and provide a choice of sweet foods.
A 1998 survey conducted by the Calorie Control Council reported that 144 million American adults routinely eat and drink low-calorie, sugar-free products such as desserts and artificially sweetened sodas. The FDA has approved five artificial sweeteners:
- Acesulfame potassium (Sunett)
- Aspartame (NutraSweet or Equal)
- Sucralose (Splenda)
- D-Tagatose (Sugaree)
- Saccharin (Sweet 'N Low)
You may be surprised to see saccharin on that list. Discovered in 1879, saccharin -- which is 300 times sweeter than sugar -- was used during World War I and World War II to make up for sugar shortages and rationing. In the 1970s, the FDA was going to ban saccharin based on the reports of a Canadian study that showed that saccharin was causing bladder cancer in rats. A public outcry kept saccharin on the shelves (there were no other sugar substitutes at that time), but with a warning label that read, "Use of this product may be hazardous to your health. This product contains saccharin which has been determined to cause cancer in laboratory animals."
That warning label is no longer needed, says Ruth Kava, PhD, RD, director of nutrition for the American Council on Science and Health. Further research has shown that male rats have a particular pH factor that predisposes them to bladder cancer. What may be true for male rats does not necessarily hold true for humans (or even for female rats); hence, no more warning labels for saccharin. "A lot of things that cause harm in animals don't always cause harm in humans," she says.
