Toots & Trots / Does it matter?
Smooth peanut butter or crunchy on toast — does it matter?
Both are the same underneath: high fat, modest GOS, low FODMAP at a 20 g serve. The difference is purely mechanical — crunchy adds intact pieces that smooth doesn't have.
Scores use a standard reference serving via the GASP model. Individual tolerance varies.
A small difference — mainly particle load.
If you notice visible roughage or residue in output, Peanut butter is the gentler pick. If you're tolerating both well, it probably doesn't matter.
