Even though some people balk at the fat content in pistachios, they are one of the most efficient foods in terms of their ratio of high protein to relatively low calories.
These nuts are energy-dense, so you feel full from the fat and fiber and have energy from the calories and protein. Studies have shown that the gut does not absorb the fat from nuts, which means you don’t retain the fat in your body once you digest them.
To get the most health benefits out of pistachios, buy them in the shell. Unshelled pistachios usually don’t have as much added salt as ones sold out of the shell. Plus, the act of shelling each individual nut helps slow down your eating, allowing your body to alert you when you’re full.
