Popular fiber supplement, Benefiber, produced by pharmaceutical company, Novartis, is sourced from wheat.
It is a fiber in the form of wheat dextrin and should therefore not be consumed by anyone wishing to be wheat/gluten-free.
Are there better sources of fiber than wheat dextrin if you are interested in regular and effortless bowel function? There certainly are:
Vegetables, nuts, seeds, chia, flaxseed, chicory inulin, fruit, i.e., real foods rich in natural fibers and mimicking the way humans have eaten for millennia. The dextrin fiber and bran from wheat are most definitely NOT necessary for perfect and regular bowel health.
