Today, I'm diving into the details of whether or not toothpaste breaks your fast!

Pssst It's officially week 2 of the New Year Intermittent Fasting Challenge and it's not too late to join in! Head over HERE for the deets on how to get started!

Are your pearly whites breaking your fast?!

But First... What's In Toothpaste?

Depending on the brand, this answer can vary widely. Standard brands of toothpaste will have various fillers, chemicals and sometimes sugar alcohols while more natural mom-and-pop brands will use ingredients such as coconut oil as the base. Generally speaking, it would work against the goals of preventing cavities by adding sugar to toothpaste - so it is unlikely that any toothpaste brand contains sugar. (a mini win!)

Does Toothpaste Break a Fast?

It depends on your goals with Intermittent Fasting. If it is for religious purposes, then it is possible that toothpaste would be considered a break in the fast. Any food, drink and sometimes even water will do that. However, for the purposes of stabilizing blood glucose levels and reducing the insulin response in order to tap into fat burning mechanisms - even if you did swallow a very small amount of toothpaste, the effect on insulin and blood glucose levels is not even measurable.

Next time you brush your teeth, you can breath a little easier knowing it won't break your fast. Just make sure you don't eat a tube of toothpaste 😉
