I don’t use sweetener often, as most of my recipes are savory in nature. However, on the occasions that I bake a little sweet treat, I always use a erythritol. The number one reason being that it is a natural sweetener. When I am purchasing products that contain sweetener, I will always search for a brand that is sweetened with erythritol. Many of the other sugar alcohols have some seriously nasty side effects. Check out this article by Kris Gunnars that details all the reasons erythritol stands out in the crowd. Get erythritol – Here
The low-calorie sweetener Erythritol may seem too good to be true.
It’s natural, doesn’t cause side effects and tastes almost exactly like sugar without the calories.
Basically, all the good stuff in regular sugar, with none of the bad stuff.
Since I’ve gotten several e-mails asking me about this trendy sweetener, I decided to do some research on it.
What is Erythritol?
These molecules are like hybrids of a carbohydrate and an alcohol (it doesn’t contain any ethanol though… the stuff that gets you drunk).
There are many different sugar alcohols. They can be found in natural foods like fruits, but they’re also added to “sugar-free” products of all sorts.
The way these molecules are structured gives them the ability to stimulate the sweet taste receptors on our tongues.
Common sugar alcohols include xylitol, sorbitol, maltitol, to name a few. But erythritol appears to be quite a bit different than the others.
To begin with, it contains much fewer calories:
- Table sugar: 4 calories per gram.
- Xylitol: 2.4 calories per gram.
- Erythritol: 0.24 calories per gram.
With only 6% of the calories of sugar, it still has 70% of the sweetness.
Due to its unique chemical structure, our bodies don’t break it down.
It goes pretty much unchanged through our system, without causing any of the harmful metabolic effects of excess sugar… or the digestive issues associated with other sugar alcohols.
Erythritol Does Not Spike Blood Sugar or Insulin
Humans don’t have the enzymes to break down erythritol.
It gets absorbed into the bloodstream and is then excreted unchanged in the urine.
Erythritol Does Not Feed Bacteria in The Mouth
One widely accepted side effect of sugar consumption is poor dental health… cavities and tooth decay.
The harmful bacteria in the mouth can use sugar for energy.
When these bacteria have plenty of energy, they grow, multiply and secrete acids that erode the enamel of the teeth.
Other sugar alcohols like Xylitol have found their way into “tooth-friendly” products, because bacteria can not digest them and use them for energy.
Multiple studies have examined the effects erythritol has on dental caries and the results are mixed. Some studies show a reduction in plaque and the harmful bacteria, while another study shows no actual reduction in caries (2, 3, 4).
What Happens to Erythritol in The Body?
There is one major caveat to most sugar alcohols… they can cause digestive issues.
Because the body can’t metabolize all of them, some travel to the intestine where they get fed to the bacteria.
But… again, erythritol is different.
Most of it gets absorbed into the body way before it gets to the colon, where most of the bacteria reside.
From the small intestine, it travels into the bloodstream.
Erythritol And The Digestive System
Unless you’re eating massive amounts of it at a time, then it’s unlikely to make you sick or have to run to the toilet.
Take this with a grain of salt however, as this can vary between people.
Overall, erythritol appears to be very safe. Multiple studies on metabolism and toxicity have been performed in test animals. Despite long-term feeding of high amounts of erythritol, no negative effects have been discovered (11, 12).
My Concerns About Low-Calorie Sweeteners in General
I did not manage to find anything negative about erythritol in any of the studies I looked at.
But I am still not convinced that low-calorie sweeteners in general are totally harmless.
This may be because the sweeteners increase the “reward value” of our foods, which can impact our brains and make us eat more subconsciously (17).
Some obesity researchers even believe the amount of processed super-rewarding foods in the food supply to be the true cause of the obesity epidemic.
Whether all of this applies to erythritol and not just artificial sweeteners like Aspartame, I do not know. Time will tell.
The Bottom Line
Overall, erythritol appears to be an excellent sweetener.
- It contains almost no calories.
- It has 70% of the sweetness of sugar.
- It doesn’t raise blood sugar or insulin levels.
- Human studies show very little side effects… mainly minor digestive issues in some people.
- Studies where animals are fed massive amounts for long periods of time show no adverse effects.
I’ve often recommended that people who must have some sweetness in their lives replace it with stevia or tiny amounts of honey.
However, honey contains calories and fructose, while many people don’t appreciate the aftertaste of Stevia.
Erythritol appears to have the best of both worlds.
