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).

Are you speaking seriously? It is new to me that stevia is not totally approved by FDA . How do you know , for example , that figs or pears or sugar from cane do not have harmful effects to our health?.- In spite of there are probably hundreds of studies pointing good things and bad (at least in case of sugar of cane) things, that they cause to our health , as far as I know , there is no study from the FDA , that has spent public money to approve or not those foods for human consumption. For only one reason . They do not need. They have been eaten by hundreds of years . They do not need to prove that they are bad to health. It only need a formal study ( with public money), if it should appear any indication that their consumption have some bad effects to our health.
That is the stevia case . In South America it have been consumed for millenniums. Its consumption is allowed in Japan , China , and I do not know if exist any other country than the States ( please tell me if exists) , where the stevia is regulated. I am from Paraguay and can say you , with the most absolute security , it will be good to your health . It was consumed by my grand grand father , my grand father , my father , me and my children .

Forget the artificial sweeteners and forget sugar. Use HONEY, which is one of the most natural and good-for-you sweeteners on earth! Read Labels and stay away from HFCS (high fructose corn syrup), which is in everything! Even canned vegetables! READ LABELS, use honey and you'll be alright!!

Off topic Regarding our dumbed-down society using "bad English:" Thank goodness that English evolves with the impact of all aspects of our society and immigration. Otherwise, thee and thou would still be using what I would called "stilted" English.

The Stevia plant is natural; it wouldn't surprise me that some people might react to it even though it might be safe (and desirable) for 95 % of the population. OTOH, the processing of the plant could cause people to be affected negatively, especially if other products were produced at the same plant, such as peanuts or seafood, or any of the many products that we normally hear cause reactions.

Sugar is nothing but harmful and dangerous, sugar is the leading cause of diabetes and obesity, so to say it is low risk is ludacris

So is stevia really dangerous? It was in my chobani Greek yogurt. The label says it is sweetened naturally with only natural ingredients. But I don't think stevia is as natural as it sounds. I still taste the difference between this yogurt and the regular chobani Greek yogurt. And I get the same after taste as I do with some diet sweetners like aspartame. I don't think people should eat stevia, I think they should just lower their sugar intake.

I had really bad reaction on Stevia in two independent cases. One time I did not know I ingested because it was part of the TROPO50 JUICE BY TROPICANA COMPANY. My tongue became numb and I was shaky.
My hands were literally in tremor. Luckily symptoms stopped soon by themselves, but I am avoiding Stevia in anything now. I do not have any food allergies and it was surprising that I react in Stevia like this. Then I started reading about it and apparently a lot of people are experiencing same symptoms with Stevia.

I looked up "sick" in the dictionary. The comparative form of "sick" is "sicker," and the superlative form is "sickest." I am a retired English prof and thought that was the case but double-checked the dictionary to be positive.
I don't usually comment on a person's grammar usage but could not resist this one.

The correct term would be poor English, if you must say.
