Dangers of Stevia
Stevia
By Cheryl Cirelli
Stevia is gaining in popularity as a natural sweetener. This natural alternative to sugar has been used for decades in countries such as Japan with little reported side effects. But, be aware that like with anything, there are some dangers and side effects to keep in mind when using this sweetener.

About Stevia
Stevia plant
Native to subtropical and tropical South America and Central American, stevia is an herb extract with about 300 times the sweetening power of sugar. Widely used throughout Japan as a sweetener, stevia is now available in the United States and Canada as a dietary supplement, but not as a food additive or sweetener.
There are several benefits that make stevia an attractive alternative to sugar such as helping alleviate high blood pressure and enhancing a person's glucose tolerance. It also is ideal for diabetics and others who may be on a carbohydrate-controlled diet.
Medicinal Problems and Dangers of Stevia
All of these with medicinal benefits notwithstanding, scientific reports have shown that the extract stevia may also be harmful when consumed. There are several medicinal problems associated with stevia.
Reproductive Difficulties
Stevia, or the singular stevioside, at least in some studies, seems to affect the male reproductive organs. This was the conclusion of a group of European scientists in early 2006.
The study showed that when male rats were fed high doses of stevioside for 22 months, sperm production was severely reduced, the weight of the seminal vesicles declined, and there was an increase of cell proliferation in their testicles. In time, this could easily cause infertility or other reproductive problems.
In another study, female hamsters were fed large amounts of a derivative of stevioside called steviol. Here the scientists found that the female hamsters had fewer and smaller offspring.
Those who are pregnant or planning on becoming pregnant should discuss using stevia with their doctor or skip using it all together.
Cancer
There have also, at least in preliminary studies, been links to cancer. In the lab, steviol can be converted into a mutagenic compound. This, in turn, may promote cancer by causing mutations in the cells' genetic material, or DNA. Scientists are divided on the issue of the cancer link, and remain adamant that further testing, studies, and reviews need to be conducted in order to resolve the issue.
Energy Metabolism
Studies conducted by the Center for Science in the Public Interest indicate that large amounts of stevioside can interfere with the absorption of carbohydrates in animals and disrupt the conversion of food into energy within cells. Scientists are particularly worried about this development, especially as it pertains to children.
Common Side Effects
The Mayo Clinic reports that there are a few side effects associated with using stevia:
Dizziness
Muscle pains
Numbness
Nausea
Gas
Bloating
These side effects are not serious and only last a short duration if at all. If you experience anything unusual with using stevia, it is always wise to contact your physician.
