Nuts are good!
Many kinds are low in carbs, so won't send your BG up. look out for Macadamia nuts, walnuts, Brazils etc. Peanuts are not true nuts and quite high in carbs. Always read the nutrition panel.
I eat a handful of pistachios when I have the munchies either mid-morning or afternoon. Doesn't seem to cause my BS to do anything unusual and keeps off the hunger pangs.
