I can tolerate glucose quite well, lived on that for months, as it's the sugar that's in Elemental028 (similar to Ensure, Fresubin etc.). I haven't eaten glucose since, as I'm just not craving any sweet food at all, but if yes, I would bake or sweeten with glucose in moderation. It is absorbed in the upper small intestine and does not need to be broken down, furthermore it does not seem to lead to SIBO or other dysbiosis issues.
