As you may know, fructose is absorbed more effectively when an equal or greater amount of glucose is present in the food. This begs the question: "Why not just eat some extra glucose (a.k.a. dextrose) when I eat to help my IBS?" This might help in some limited situations if, and only if:
- You have fructose malabsorption
- You are eating a food containing excess fructose but no other FODMAPs
Since most people with FODMAP intolerance have trouble with multiple FODMAPs, and since many foods contain multiple FODMAPs, that really narrows down the potential for help from this trick. An apple, for example, contains sorbitol in addition to excess fructose. Still, some of you may find it worth trying.
Rolls of glucose/dextrose tablets are sold with diabetes supplies at the pharmacy. Some hard candies like Smarties are mostly dextrose.
