Is There a Safe, Low-Calorie Sweetener?

The natural sweetener erythritol does not appear to carry the adverse effects associated with other low and non-caloric natural and artificial sweeteners and may actually have antioxidant potential. For a while it was only available in Japan but now it’s becoming more accessible. It’s found naturally in pears and grapes, but industrially we have yeast make it for us. It doesn’t cause cavities and hasnít been implicated in some of the disorders tied to other sweeteners such as fibromyalgia (see my video Aspartame-Induced Fibromyalgia), preterm birth (Diet Soda and Preterm Birth), headaches, hypertension, brain disorders, and platelet disorders (see A Harmless Artificial Sweetener).

What about stevia? The jury is finally in. The reason itís been such a long time coming is that research out of Japan in the ’90s found that steviosides, the active ingredient in stevia, appeared totally harmless, but in the guts of rats intestinal bacteria transformed steviosides into something called steviol, which is toxic, causing a big spike in mutagenic DNA damage (see the graph in Is Stevia Good For You?). So the question was do we have those same rat bacteria in our guts, and it turns out we do. So we now know that when we eat stevia, mutagenic compounds are produced in our colons and absorbed into our bloodstream. The only remaining question was how much.

In the World Health Organization’s evaluation of food additives, they consider up to 4 mg/kg of body weight safe. So thatís 1.8 mg per pound. If you multiply your ideal weight in pounds by 1.8, thatís about how many milligrams of stevia compounds you should stay under on an average daily basis. As long as one consumes less than, say,† two stevia-sweetened beverages a day, stevia can be considered harmless. Erithritol may be even better than harmless, though, as you can see by clicking on the video pick above.

There are two caloric sweeteners that are health-promotingócan you guess which ones? Check out The Healthiest Sweetener for a comparison of agave nectar, blackstrap molasses, brown rice syrup, corn syrup, brown sugar, date sugar, honey, maple syrup, raw cane sugar, and turbinado sugar.

I figure I'm old enough now that it doesn't really matter to me so I will continue with my 1 or 2 cups of coffee with sweet-n-low, like I have for the past 40 years. I am concerned about the things my grandchildren are exposed to though. I'm especially concerned about aspartame, since I have been hearing bad things about it for most of my life, especially when used in hot or to-be-heated items.

I've been using a tiny bit of stevia per day and thought it was a healthy alternative. Seems there really isn't one.

Erythritol - Truvia sweetener a powerful pesticide; scientists shocked as fruit flies die in less than a week from eating GMO-derived erythritol.
A shocking new study published in the journal PLOS ONE (1) has found that Truvia, an alternative sweetener manufactured by food giant Cargill, is a potent insecticide that kills fruit flies which consume it.The study is titled, Erythritol, a Non-Nutritive Sugar Alcohol Sweetener and the Main Component of Truvia, Is a Palatable Ingested Insecticide.

The study found that while fruit flies normally live between 39 and 51 days, those that ate the Truvia ingredient erythritol died in less than a week. Check it out:
