If you're trying to stay away from refined sugars or artificial sweeteners, you have a number of options, of natural food ingredients, that can be used in their place. One of your options could be to use fig syrup, a.k.a. miele di fichi or fig honey.
Personally speaking, fig syrup tended not to aggravate my intestinal flare-ups. It may also be a good option for you if "fiber is not your friend".
In Canada, this product is basically impossible to purchase. So, you'll have to make it yourself. Don't worry. It's actually quite simple. Click here for my recipe.
