Pistachio nuts were a common food in what is now northeastern Iraq since at least 6750 B.C. The pistachio has been promoted as the “skinny nut” since at least January 2009. The book The Secret to Skinny (2009) stated:
 
“Pistachios are the skinny nut. They’re one of the lowest in fat, highest in protein, and highest in fiber, which means they are one of the few protein source that have fiber to help unplug you while satiating you.”
 
   
Wikipedia: Pistachio

The tree produces an important culinary nut.

The Skinny Nut. **Giveaway!**
Back in October, the folks at Everybody’s Nuts sent me a sampler of their Pistachios. I am a big fan of pistachios and an even bigger fan of freebies, so I accepted their sampler box and expected to be no more or less impressed with Pistachios than I was before I tried them. Though, I was grateful nonetheless for the chance to give new flavors a try.

New Research Supports Pistachios as the “Skinny Nut”
FRIDAY, JULY 15, 2011
This week, two mindful eating studies supporting pistachios as the Skinny Nut were published in the journal Appetite.  In the first study, Eastern Illinois University researchers found that participants who consumed in-shell pistachios ate 41% fewer calories compared to those who consumed shelled pistachios.  In the second study researchers found that pistachio nut shells can provide important “visual cues” as a reminder of consumption that translate into a 22% reduction in calorie consumption.  Both studies further underscore that in-shell pistachios, which are one of the lowest calorie nuts, are a practical, everyday snack for weight management.
