Is Stevia/Truvia/PureVia A Safe Sweetener?

August 16, 2011   44 Comments

The leaf above is from a Stevia plant and the powders and pills are the sweeteners derived from it. What is Stevia?

Are Stevia, Truvia or PureVia Safe?

Stevia is a South American plant from the chrysanthemum family, grown and used by locals for its sweet tasting leaves.

Stevia extracts are 200-300 times sweeter than sugar, but contain no calories. This has made stevia an alternative to sugar and artificial sweeteners such as aspartame and saccharine.

What is the difference between Stevia and artificial sweeteners?

Stevia is an herbal extract. Aspartame, saccharine, or sucralose (Splenda) are made from chemicals in a manufacturing plant.

But, the leaves of the stevia plant are not just ground up and served to us. There is a bunch of processing that goes into getting the best calorie free sweetener.

Manufacturers want to isolate Rebaudioside A because it has the least bitterness of all the sweet compounds in the stevia plant. To produce rebaudioside A commercially, stevia plants are dried and subjected to a water extraction process.

This crude extract contains about 50% rebaudioside A; its various glycoside molecules are separated via crystallization techniques, typically using ethanol or methanol as solvent.

At this point, you begin to wonder if there is a BIG difference between an herbal extract and a synthetic sweetener. They both spend some serious time in a manufacturing plant.

In December 2008, the FDA gave rebaudioside A (or reb A) approval for "Generally Recognized As Safe" status. Back in 1991, the FDA restricted stevia's import because there wasn't enough toxicological information to demonstrate its safety.

What changed? Well Cargill and Pepsico both developed reb A products, Truvia and PureVia (respectively). And, there have been more toxicological studies showing that it doesn't cause cancer.

But, is it safe?

There is one outspoken group - the Center for Science in The Public Interest - that believes that there should be more study of stevia in mice before we start a large experiment on ourselves with the stuff.

You see there are a bunch of studies in rats - but, they believe, not enough research in mice to prove that stevia is safe.

The good news is that stevia didn't cause cancer in rats and that the World Health Organization (WHO) did a study in 2009 and also concluded that stevia is safe.

My thinking is that as with any additive, the best plan is moderation. If you like the taste of stevia than use it to sweeten things - but don't go over board.

No toxicological study is going to be able to gauge the effect of large doses of anything on humans over many years. We are just subjected to too many different environmental factors.

What do you think of stevia based sweeteners?

I found that when I used Splenda for a while, my body started to get aches and pains. When I stopped, I felt much better. Now I am using Truvia but am feeling achy, joins hurt, etc. again. Not sure if it is my imagination or not. Will quit any "non-sugar" and see what happens. Does anyone else experience this?

I was diagnosed as Insulin resistant about 4 weeks ago. Since then, I have learned that Stevia is the only "safe" sugar substitute for my body. Artificial sweetners cause your body to produce more insulin because it thinks you are having sugar. THIS IS NOT GOOD. Stevia, however, reacts in your body differently than other artificial sweetners. It does not cause an increase in insulin production. This in turn lessens the cravings for sugary foods and drinks. Trust me, I didn't believe it at first but 30 days later, I am proof!!

on August 16, 2011

I rarely use artificial sweeteners. But if I have too much Splenda, I know it because I feel headachy. But I have not had the same reaction with Stevia so far.

on August 16, 2011

Although I'm generally all for whole foods, a little processing isn't always a horrible thing. Pasta is a processed food - and I'll buy it because I sure don't want to make it myself. (I have made pasta from scratch - and I swore I'd never do it again!) Yes, real Stevia does go through some processing but if you're getting the real thing no additional ingredients should be added. That is not true with Splenda, Truvia, or PureVia. And that's where things get tricky. An ingredient in Truvia is "natural flavors" - what does that even mean? (hint: think corn).

I recently wrote about artificial sweeteners: http://www.anorganicwife.com/2011/08/all-about-artificial-s… and natural ones: http://www.anorganicwife.com/2011/08/list-of-natural-sweete…

on August 16, 2011

With all other artificial sweeteners I have experienced an aftertaste. Not true with Truvia. So I do use it in moderation.

on August 16, 2011

I have used Stevia w/ chromium , I us about 3 packets a day for hot green tea. I haven't heard any negative from Stevia. I bought it at the health food store. I guess we can all use Honey or Agave!

on August 16, 2011

it's not even legal here in the UK!

on August 16, 2011

I don't really like the taste of Stevia, so I don't use it. I also found some claims online about people who used it who had extreme carb cravings. Seems strange, but there were quite a few reports out there on the interwebs...

on August 16, 2011

Cathy, I'm wondering about what you said - not necessarily about stevia alone, but other natural sweeteners like sugar alcohols (like they put in vitamin water zero). I've been drinking large amounts (several bottles a day) of vitamin water zero, and in the last few weeks I've noticed that my fingers are stiff and hurt - I've been concerned that I'm getting early onset arthritis (I'm only 39). But I wonder if it's something to do with these "natural" sweeteners... Maybe I'll do a "no sweeteners" test too and see how it goes...

on August 16, 2011

Yes, in response to the stiffness and pain in the fingers. That happened to me too. Really weird. I, too, think I will either use REAL sugar or no sugar for a while and see what happens. Thanks!

We need to examine how often we are enjoying cakes, cookies, and sodas, and consume them less. There is so little food value in these types of foods. They don't make us look and feel better, so why do we eat them as frequently as we do? Eat real sugar, but eat it infrequently. You don't need to eat a cookie or some cake every night. Why are we poisoning our bodies with lab-created sugars?

on August 16, 2011

I've been using stevia in my coffee for about 2 months now in an effort to break my sugar habit. I figure/hope it's better for me than the sugar. FYI: I'm using a French press for my coffee now & I use less sweetener that way (since the coffee tastes better). I also switched from half & half to dark chocolate almond milk. Have a good day :-)

on August 16, 2011

I use pure stevia extract powder most of the time, but in cooking I started looking at Truvia and Stevia in the Raw. Truvia had 7 carbs per serving. Stevia in the Raw had less than 1 and stevia extract powder had none. It makes you wonder what they have snuck into Truvia to add 7 carbs per serving.

on August 16, 2011

Remember that Truvia and Stevia are not the same thing. Stevia is generally derived from the whole leaf. While there is a process to make it into a liquid or a powder form, it's based on the whole leaf. Truvia is based on the extraction of the single compound. It's not a whole leaf product. Just as refined grains have little to do with the health benefits of a whole grain, whole leaf stevia has little to do with Truvia. Knowledge is power!

I have out-of-body experiences with Splenda!I'm a fan of Zero Vitamin Water which contains stevia extract. It agrees with me.

on August 16, 2011

Actually I have a quick question...what kind of "real sugar" does regular (non diet) soda use? The reason I ask is that Pepsi recently did that Throwback promo where they're using "real sugar" again for their regular pepsi soda. So then...what have they been using for the non-Throwback and non-diet Pepsi all this time? O___o

on August 16, 2011

We've been using NuStevia for a while & like it very much (http://www.nunaturals.com/). There is no aftertaste and a little goes a very long way. We were recently introduced to xylitol as a sweetener and are trying it out as well. We like that neither of these sweeteners spike blood sugar, as diabetes is a problem in both of our families.

on August 16, 2011

I do have to add to some comments about using real sugar~ my yoga instuctor from India says she uses the brown raw sugar. Its pure and natural and safe, she uses it in all her baking and dishes. Now that makes a lot of sense! And she said of course "in moderation".

on August 16, 2011

One thing that can be said for Stevia is that it has been used in Asian and South American countries for a long time. Whether their version is less processed than ours is a good question though. I will say, unfortunately it's too strong tasting for me to put in coffee, and I usually only use it in tea, which is disappointing. I have only used the Trader Joe's brand though, not the new Pepsi brand which might taste better.

on August 16, 2011

How is "real sugar" made? I thought it was processed from beets?

on August 16, 2011

Also wanted to ask: what's the difference between rats and mice for reseach purposes?

on August 16, 2011

I have been using Sun Crystals for about two years now. It is stevia and pure cane sugar mixed. At first I noticed a gittery funny feeling after eating it. I would say it lasted about a week or two after first trying the product. Afterwards, I guess my body got used of it.

I love it for my tea, oatmeal, etc. The bad news is that it has been discontinued for low sales. I wish they would start putting stevia in more items as an alternative to aspertane and splenda. Splenda makes my stomach hurt after too much. It would be wonderful to have a low calorie alternative.

on August 16, 2011

I actually grew stevia in my herb garden last year and it was fun to add to iced tea. I was tickled, though, because it has an artificial aftertaste, even though it's straight from the garden.

on August 16, 2011

Can somebody tell me what 'real' sugar is? Because there's all kinds of sugar, and granulated/white sugar isn't exactly good for you.

I use cane sugar (I'm not sure if it's organic, but it contains no beet sugar) and evaporated cane juice in my baked goods

Thanks for posting. This is very helpful. I steer clear of artificial sweeteners because they give me headaches. I once asked my doctor about them (and the headaches) and she told me to stay away considering my reaction. Fake sugar is really in so many things these days and you really need to read the label carefully!

What about agave nectar?

on August 22, 2011

My stevia is a green powder derived from the whole leaf, not a stevia-based white powder product. I buy an ounce or two from a trusted supplier as needed.

I have been using it for at least 10 years, with no side effects that I know of.

It really is very sweet but will taste bitter if I use a smidgen too much. For this reason, I only use it for tea and literally use barely a pinch. My few ounces last a long time.

.

There is evidence that stevia in large doses may cause some health issues (http://cspinet.org/nah/4_00/stevia.html).

.

There is also evidence that it can be beneficial to some as well (http://www.diabeteshealth.com/read/2006/08/01/4813/steviaa-…).

.

There is a wealth of information available about stevia. Before I made the decision to use it, I sought answers pro and con and made an informed decision I was comfortable with.

Thanks Erin! like the idea of the sleetweaf root beer liquid stevia in sparkling water. I tried the vanilla stevia in a mint sparkling water and it was pretty good too.

on February 22, 2012

The Stevia plant(i am sure some forms are better then others) is the most natural low calorie sweetener out there at the moment.

on July 3, 2012

My sister has stevia plants on her window sill. She picks a few leaves, lets them dry, and crushes them into whatever she wants sweetened. No processing problems there and we love it!

on July 31, 2012

Equal causes major problems for me.

I want to use Splenda (maybe 2 packets/day) but I notice stiffness and *headache* so I just keep trying to keep sugar intake low (and trust me, it is a battle!). I am off all soda (yay!) and have sugar in my coffee in the morning. 1/2 stevia in flavored iced tea in the afternoon, but I really don't care for the taste in general.

Xylatol makes my tongue tingle so I don't know what that's all about.

on July 31, 2012

Shannon,

They use corn syrup in regular sodas!

on October 24, 2012

Stevia makes me break out all over my neck and face with itchy bumps... every single time I try it. Now that I know that, I have to go through great pains to avoid it because it seems they are SNEAKING it into EVERYTHING! My philosophy is stick with items that are as close to nature as possible. This lab created stuff is dangerous!!!

good info

I get migraines from artificial sweeteners. Stevia does not bother me. I was surprised when I was using Truvia (thinking it was the same as Stevia) and I got migraines again. Hmm. I stick with plain old liquid stevia. Now, strangely enough, a big dose of sugar (such as the crack cocaine that is a pint of B&J)will trigger a headache the next day, like a hangover.

I am trying to retrain myself to just enjoy foods the way they come naturally, without adding salt and sugar. It's hard though, for an addict, such as myself.

My husband has been diagnosed with type 2 Diabetes, he used to consume alot of sugar and carbs. When I found out that artificial sweetners were bad we started using organic Stevia. My husband feels unhappy when he can not have sweets and I hope the Stevia is healthy.

on May 14, 2013

Too much Stevia can taste bitter. Use very little.

Most sugar alcohols can cause diarrhea.

Here is the place with the brand of Stevia that I like. No after taste.

on July 28, 2013

I've not used the granulated Stevia but use the liquid concentrate all the time.

I make my own ice cream with it.

I discovered that the aftertaste comes from using more than is needed. If adding it at the table, start with half or less than what you think you'll need, then add more if desired.

Also, find a brand you like that is consistent from bottle to bottle or you will likely find it hard to regulate the quantity needed. I like the NOW brand.

For soda, try Zevia.

Don't know much about PureVia and have never tried Truvia, but I believe the processing of these products make them much less desirable regular stevia.

I have no connections with either NOW or Zevia except to be a satisfied user of their products.

on September 25, 2013

DO NOT USE TRUVIA, if you really want a "no colorie sweetener" just simply grow the plant yourself. Truvia is proccesed with "additives". @ cathy- Were you using truvia or purevia because you conversation went to vitamin water 0 which makes me think you were, try the real plant pot it in a sunny window and simply take off leaves :)

on October 2, 2013

I've been following Haylie's "fast metabolism diet" for two months now and use the Stevita brand of stevia and notice no aftertaste. In her link below she does a good analysis of the sugars and makes recommendations.

sallyjw...that is what my husband said. we go through beet farms out west and out comes the sugar trucks (domino, etc)

my comment was about anything but real sugar...vitamin water, gatorade, powerade included. i will have same reaction to those as i do when i come into contact with anything made with aspertame/ sucrolose/ sacchrine in it. why would i have reactions to the drinks if they were not made with my 'fake sugar' allergens?

on August 18, 2014

I see a lot of conversations about artifical sweeteners and safety but I don't see anything asking about the safety of sugar. Sugar is no more safe than something like stevia. I think there are enough studies and the epidemic obesity problems that shows us that sugar is harmful and addictive. I liked an op-ed piece by a pediatrician who allowed his kids to consume stevia products (in moderation) but extremely limited their consumption of sugar. If you are going to discuss the health of sweeteners, sugar needs to be part of the conversation. Just because it is in everything does not make it healthy. Just because it is "natural" does not make it safe - or are you into everything natural like arsenic and hemlock.

"Real" sugar would be Cane Sugar at best, or likely from Sugar Beets. The Non Real Sugar used in soft drinks is almost always High Fructose Corn Syrup.

on July 13, 2016

I have used both Truvia and PureVia and they tasted fine. I have yet to find any Stevia that I didn't think tasted bad. I would like to find one but no luck so far. I use Splenda in my one cup of coffee and now and then in cereal.
