My grandfather used to loooove them and would rock the stained fingers :)
Pistachios have the lowest calories per serving compared to most tree nuts:
30 pistachio nuts=100 calories
30 almonds= 207 calories
30 cashews= 266 calories
30 walnut halves= 407 calories
30 pecan halves = 315 calories
Per 30 nuts you get 2 grams of filling fiber, 4 grams of protein, and 8 grams of healthy fat!
A GREAT snack for those watching their weight or for just about anybody who wants something nutritious and delicious!
