Question: are pistachios hard to digest?
Answer: Pistachios, cashews, hazelnuts, and almonds: avoid Most nuts are good for your tummy, but pistachios and cashews are high in fructans and GOS, both FODMAPs. Hazelnuts and almonds are a little higher in FODMAPs than some other nuts so eat them in limited quantities (10 nuts or 1 tablespoon nut butter per serving).
