Is Stevia Safe?

A. This year, a few noncaloric sweeteners made from an extract of the Stevia rebaudiana plant arrived on grocery-store shelves. The stevia plant has a long history of use as a sweetener in South America. These new sweeteners—sold under brand names like Truvia and PureVia—include a highly purified extract of stevia called Rebaudioside A (a.k.a. Rebiana or Reb A). Reb A is 200 times sweeter than sugar and does not raise blood sugar.

Until December 2008, stevia and its derivatives could be sold in the U.S. only as dietary supplements, due to safety concerns. In the 1980s, animal studies linked stevia with adverse effects on fertility and reproductive development and possible genetic mutations. But in 2008, the makers of Truvia and PureVia submitted research to the Food and Drug Administration regarding Reb A’s safety and petitioned for it to become a generally regarded as safe (GRAS) ingredient.

The FDA affirmed the GRAS status, but did not change the previous ruling on stevia. “Reb A is different than whole-leaf stevia or [other] stevia extracts, which can only be sold as dietary supplements,” says FDA spokesperson Michael Herndon. “Nobody has provided the FDA with evidence that whole-leaf stevia is safe.”

The Center for Science in the Public Interest (CSPI), a consumer advocacy group, believes that the Reb A’s GRAS status was granted prematurely. “In the past, FDA protocol required repeated testing in two separate animal species prior to approval, but in this case it didn’t,” says David Schardt, nutrition expert with CSPI. “We are not warning people to avoid Reb A, but the public should be aware that the FDA did not follow all the usual safeguards.”

Bottom Line: The FDA considers Reb A a safe sugar substitute, but has not approved other forms of stevia. If you want to use stevia, we suggest sticking with Reb A (look for it on the ingredient label).

Stevia (Pure stevia not the branded products produced by big ag) is a wonderful substitute for cooking and beverages. We have been using it for years (since around 2001 when we were looking for an alternative to sweetener that wasn't chemical). We use it even more now with one of us on a Paleo diet. As to the reference to Super Size me I strongly recommend watching the movie FatHead and doing some related research. eat at home if you want to eat healthy but eat smart not corn syrups etc (unnatural cornsyrup causes so many problems!) Stevia is economical and while it can't be directly substituted in some recipes it can be used with great success in many. Thanksgiving saw my first effort in sugar and gluten free pumpkin pie with just a wee bit of stevia powder (3/4 tsp of pure) and well.... they want more!!

Oddly enough, Stevia plants grow very well on the Central Coast of CA. Dried and ground up leaves seem to be a very good sugar substitute. Prof. D. Williamson

I've been growing it my garden for years. It really does satisfy a sugar craving on a hot summer day, even my 4 year old daughter likes it. I also just found a new soda called "Zevia" which contains Reb A, and its pretty good.

The main ingredient in powdered Truvia and Purevia is some kind of sugar (erythritol [a sugar alcohol]and dextrose, respectively). The second ingredient is a patented form of stevia. If you want legitimate, natural Stevia, WHICH IS OBVIOUSLY SAFE, get a brand that has inulin, a soluble vegetable fiber, as the main ingredient (Stevia is too sweet to be used alone, because the usable quantity would be too small to be practical). "Sweet Life" is a good choice. You can also use the liquid form in a one or two ounce bottle with a pipette (my preference). It should contain nothing but stevia, water, and either alcohol or glycerine. It's safe, convenient, and goes a very long way. Just avoid the big name brands, which are using sugar and a patented type of stevia.

The FDA can't approve anything unless it's proven! Proven what? In some cases proven to be dangerous, like saccharin, aspertame, and sucralose. They're on the market having now been proven dangerous. Stevia, the only natural one in the bunch, and it can't be approved, because no one will research it, and prove it to be...what? dangerous? safe? What a racquet!

Processed sugar that we buy in stores are bad because they calcify the Pineal gland in our brain. As does the flouride that is in our toothpaste, drinking water and tapwater. The calcification of our pineal gland causes excessive damage to our bodies. Do your research on what you put into your body and how it affects not only your health but your brain as well. Nourish your mind and body & spirit will follow! The homework really does pay off by living healthier and longer.

I wouldn't put all my trust into the FDA. They approved aspartame, after all.
