Safety

The FDA has not given stevia the “generally recognized as safe” label; however, the herbal compound has been used for hundreds of years without any recorded side effects. Japanese studies found that the sweetener consistently yielded a non-toxic status, even after extensive toxicity trials. The Japanese have used stevia for years with the approval of Japanese control agencies, and in Paraguay the herb has enjoyed hundreds of years of consumption with no reports of detrimental side effects. No anomalies have ever been observed in cell, enzyme, chromosomal or other significant physiological parameters during these toxicity tests. Stevia has not been associated with any form of cancer or birth defects. Stevia consumption in Japan was approximated at 170 metric tons in 1987 with no cases of documented side effects. Scientific Toxicology Studies Comprehensive and tedious clinical studies in Japan have more than established the fact that stevia can be taken safely. One such study used over 450 rats who were fed stevia for up to two years with doses many times greater than human consumption. No changes were observed in organ weights, blood biochemistry, growth, appearance, or cellular function. The Japanese have found no indication that stevia affects fertility or unborn children and have never linked it to cancer or other cellular mutations. (NOTE: Diabetics and people with other medical conditions should always consult their physician before using this or any other dietary supplement and should never alter or stop their medication unless advised to by their physician.)

If you fall into the category of a consumer who is searching for an excellent natural sweetening agent which is safe, powerful, and calorie- free, stevia extracts should be first on your list. Ironically, while enormous quantities of aspartame and saccharine continue to be consumed in this country, a sweetening substance that poses less risk and is more effective continues to be rigorously regulated. Fortunately, restrictions are easing and it is now possible to purchase stevia as a supplement. Both xylitol and saccharine have been linked to tumor development and aspartame continues to prompt controversy in its reported wide range of negative side effects, yet all of these products enjoy unrestricted marketability. It is rather ironic that chemical compounds that have the capability of wreaking all kinds of havoc with human physiology have the advantage over natural substances that are certainly much more benign. It’s hard to imagine that a safe, natural herb which offers concentrated sweetening power and may also actually normalize blood sugar and prevent tooth decay remains relatively unknown. Stevia will inevitably emerge as one of the best non-caloric sweeteners available. It’s just a matter of time before American consumers discover its extraordinary attributes. In the meantime, learning to use stevia dietary supplements can provide us with the ability to “sweeten” our lives without compromising our health. There are over fourteen current clinical studies on stevia listed in Medline which discuss various biochemical
attributes of the herb’s glycosides.
