Stevia is too new to make any real determinations on. Currently, there is a lot of uncertainty. Just because something comes from a plant doesn't make it safer. Almonds used to be loaded with cyanide before we eliminated the trees that had those kinds of almonds. There have been recent studies questioning the safety of stevia, and this will likely be dealt with over the next decade. Unfortunately, certain countries have gotten around the necessary procedures for sufficient scientific inquiry because they are marketing it not as a food additive or sweetener but as a dietary supplement, which makes it easier to avoid such scrutiny. Unlike xylitol, which is perfectly fine for human consumption and has been shown to inhibit growth of oral bacteria that leads to caries and plaque, stevia is simply an unknown at this point.

However, stevia has also been around for a while. It has been a product since the 90s and has been banned and un-banned in numerous countries. European reports have shown that it is safe, but it is also still banned in many countries there.

For those of you think that it is "natural" and thus safer, I urge you to look up the naturalistic fallacy on wikipedia before going any further here. It has also been used as a sweetener by certain tribal peoples for centuries, so that means absolutely nothing as far as science goes, but it will still sway many people over, just like traditional herbal Chinese medicines like tiger penis powder and rhinoceros horn powder.

However, it is not a "natural" substance whatsoever, even though that word means nothing in nutrition anyways. Basically they take a small amount of Rebaudioside A from the stevia plant and use a bunch of alcohols and other chemicals to extract out the active sweetening ingredient and then crystallize it. This is then renamed steviol. It is significantly less sweet than most of the other sweeteners, except maybe saccarin, at only about 150x the sweetness of sugar.

Basically, Stevia is probably not bad for you, although the verdict is definitely not in on this one. It is no more "natural" than any of the other sweeteners. You need more of it to reach the same level of sweetness as your other sweeteners so dosage could be an issue. But you have to understand that each of the companies that makes these sweeteners has to find a way to sell their product. So, what do they do? They claim that their sweetener is "natural" and "safe" which implies that all of the other sweeteners that came before it aren't, and as evidence by my previous tirades, this is simply not the case. But they profit from our unwillingness to look at the data for ourselves and play on our natural tendencies to trust them.

In short, we are not certain about stevia yet, but we are certain that sugar is bad and aspartame is fine. However, you probably shouldn't eat any processed food, but we already know that in our bones. We all know that cooking up a delicious meal from simple ingredients is the best way to eat healthy but we don't do it because we are lazy. I am just as guilty of this as the next person. We can only dream of a future similar to "The Invention of Lying" where marketers aren't allowed to lie to us and can simply say that their food is bad for you but you drink it because it tastes good and because you have been for years. A world where they can't market to our children so we don't all grow up addicted to halloween candy or cereals that are more sugar than grains. The best way to do this is to cut your cable from the television and live on the internet with AdBlock installed. Then those fuckers can't get at you as easily.

Chocolate can be toxic to dogs. Regular candy isn't (sugarfree/xylitol is also a no-no), just bad for the teeth if they eat a lot But this was just a few pieces.

Sure hope it's isn't that dangerous, I'm sitting here with a bottle of NaF (Sodium fluoride) [Edit: Sucky pills] that I got from the dentist. And there's plenty of it in the water to being with. "Should not be used in regions where the fluoride in the water is adequate." How do I know that?

I bet the Xylitol and Sorbitol mixed into these have some effect too.

Edit: A bottle of NaF would be cool, 5-10g can kill a person.. The possibilities would be endless!
