Xylitol: Answers to Your Questions & What You Need to Know

Finally, some real answers about xylitol…

Xylitol Answers

Why is xylitol so important?

There are some people writing negative articles about xylitol. In a way I understand, because commercially it’s made in a lab, but so are most vitamins. The most important part is that it is something that exists in nature and not a synthetic chemical. Xylitol will not be good for everyone (as is the case for most things!) but it is a very beneficial tool for many as they start their journey to cut down on the amount of sugar they’re consuming.

Xylitol is in small amounts in many fruits and vegetables (up to 10%). And while I wish we had a way for commercially extracting it from these fruits, it’s just not commercially viable… yet (come on creative food scientists!). But the reality is we NEED xylitol. We are in a health crisis of sugar consumption, eating 600-800% more sugar than our bodies can handle, and we NEED a solution.

Yes, not eating anything with added sweetness is the best, but it’s not going to work for everyone. So, we have xylitol, which is the most researched, best tasting, easiest to use, sugar alternative out there. Right now, we simply need it. While not as deeply studied, nor as easy to use, we also recommend erythritol, stevia extract, and monk fruit, but xylitol is our favorite.

We don’t use it as often anymore as we’ve adjusted our tastebuds to not crave extra sweetness as much, but as we initially made the decision to completely stop eating sugar. xylitol and xylitol sweetened dark chocolate was a lifeline for us for many years, and it worked very well for us.

5 reasons I use xylitol.

  1. It’s my absolute favorite tasting sweetener that does not contain a form of sugar (glucose/fructose).
  2. It is the easiest sugar alternative to bake with since it has similar weight and sweetness as table sugar, so you don’t need to change the rest of the ingredients in the recipe.
  3. It keeps my teeth healthy. Read more about the tooth health benefits of xylitol here.
  4. Opposite to sugar, xylitol actually donates a hydrogen helping to rebuild NADH and glutathione. In simple terms, an antioxidant, and when combined with chocolate (see next point), just can’t be beat.
  5. It makes really, really good chocolate. (This obviously being the most important reason.)

Xylitol – what is it and how does it work?

You may have read a multitude of opinions on xylitol from it being the best sugar alternative, low-carb athletes’ secret weapon and best friend to your teeth, to the opposite opinion of it being a dangerous chemical that can kill a dog.

So, what is xylitol, why does it have a weird name, and what is the truth of this debated powder?

Xylitol comes from the Greek ‘xyl’, which mean wood and then gets the ‘itol’ since it’s an alcohol sugar like sorbitol and erythritol. So, it’s wood sugar. Not surprisingly, a large portion of xylitol comes from birch and beech trees where it exists as xylitol in its simple sugar form xylose. In nature xylitol is found not just in wood, but a large array of foods we already eat on a daily basis. 10% of the sugar in a plum is xylitol. So yeah, it is natural.

Xylitol is an alcohol sugar. Most alcohol sugars are laxative if too much is eaten. This is true of xylitol as well, but it is the second LEAST laxative, just behind erythritol. (For me, erythritol never worked for my gut whereas xylitol from birch worked well, maybe because erythritol is only made from corn). So, if you have had bad experiences with sorbitol and maltitol, xylitol is not at all the same. Still, if you have a sensitive stomach or IBS, proceed with caution or steer clear. What works for many is start small and increase slowly.

Is xylitol paleo?

Xylitol is used by some paleo authors and bloggers. That said, not everyone is for it. While xylitol is paleo in the sense that you could naturally eat it with no processing (for example in plums), it also could be argued that it’s not paleo since the commercial version is processed.

Is xylitol dangerous for dogs?

Yes and no.

It’s not so much xylitol itself, but xylitol by itself. A plum (other than the pit) isn’t dangerous to dogs and xylitol is up to 10% of the sweetness in a plum. The problem is that dogs have a strong insulin response to pure xylitol and xylitol doesn’t use insulin to be metabolized. Humans don’t have an insulin response to xylitol. Good news for diabetics, not for dogs. If a dog gets pure xylitol, it will release a large amount of insulin, effectively putting the dog into a diabetic coma.

So, what should you do if your dog gets into your xylitol baked goods? There’s quite a mix of advice out there, not much of it good. I’ll leave it up to the vet to tell you what to do, but since many don’t know about xylitol, here are a few things to talk to them about: Since xylitol causes a dog’s blood sugar to drop, it seems logical to get glucose in as quickly as possible – anything sugary. Some vets put dogs on a glucose drip as soon as they come in. Remember, 10% of the sugar in a plum is xylitol, so it seems it’s not xylitol itself that is poisonous to dogs, but xylitol by itself, with no other sugars, that is the big problem.

Beneath the Layers

Rock Layers

In the beginning of the journey of work clients and I venture on, the surface issues and discussions are initially “just surface.”

In fitness, when there’s a movement a client cannot perform after much practice and polishing, the first thought is that they just can’t do it.  Soon enough, we discover their central nervous system has protected their body from moving in that specific manner, because there is a limiting belief and limiting decision their central nervous system and their unconscious mind have a greed upon. And it has defined itself as “safety.”

When clients want to lose weight, we later on discover the emotional un-resolve rooted in eating patterns inhibiting them from their success of doing so. Sometimes, more often than others, there’s systematic problems inhibiting digestion promoting bloating, infections wreaking havoc, and the list goes on.

Mental blocks become obvious as we begin to peel away the layers. We eventually become acquainted that the behavioral “issues” desired to be changed, are very obvious physical symptoms or manifestations breeding beneath deeper layers.

There’s a lot of “stuff” we stuff. That “stuff” will introduce itself to you and the world around you, eventually. Self preservation can feel “safe” and comfortable. But it is unsustainable. Eventually the totality of us, will beg to be resolved. Lean in listen and learn. Eventually you will heal.

“We will project that which is unconscious in the most obvious of ways in order to become consciously aware which is most unconscious so we can gain the learning necessary to get results.”- Nathan Rossi
