What to know about cashew nuts
As a snack, cashew nuts are the highest-FODMAP nut you can grab: Monash rates even 10 nuts high FODMAP, driven by both fructans and a very high GOS load. That is why a handful of cashews bloats people who tolerate almonds or macadamias fine. They also run high in nickel and rate poorly for SIBO, so cashew nuts are an easy trap when you are snacking to trigger-test.
Watch for
- One of the highest-FODMAP nuts, high in both fructans and GOS, so a small handful can bloat a sensitive gut
- Even 10 cashews are enough to cross into a high-FODMAP serve, unlike most snack nuts
- Poor for SIBO, since the fermentable carbohydrates feed bacterial overgrowth
- High in nickel, worth noting if you have systemic nickel allergy
