Does monk fruit sweetener break a fast?

Q: Does monk fruit sweetener break a fast?

Maybe - use caution. Usually fine by calories. The fasting issue is not monk fruit itself; it is the product blend and whether sweet taste triggers appetite. Use the smallest amount that works, and check the label for sugar, maltodextrin, or calories.
