Why Cashews may feel difficult
Cashews are high in both GOS and fructans, so they are commonly limited during a low-FODMAP elimination phase.
Gas can build when fermentable carbohydrates reach the large intestine and gut bacteria break them down. The same food may feel fine one day and harder during a sensitive week.
For people with IBS, the total meal matters. A food can feel different when it is paired with wheat, dairy, beans, sugar alcohols, large portions, alcohol, or a stressful day.

| Regular serving | Higher-FODMAP pattern during elimination |
Lower-FODMAP alternatives
Walnuts (30g) can be a useful swap. Walnuts offer a similar crunch and are commonly listed with measured lower-FODMAP servings.
