Interpreting FODMAP content of foods in clinical practice.

The article by San Mauro Martin et al raises the important issue of discrepancies in the FODMAP food-composition data published by various sources. The Table compiled by Martin et al provided no indication of serving size, so it is not clear whether the discrepancies reflect true differences in FODMAP content, or simply differences in FODMAP ratings arising from differences in the selected serving size and/or cut-off criteria for high or low content.
