Pistachios in the News!


A new research study, using an experimental model that mimics digestion, suggests that neatly all of the polyphenols in pistachios are released to the body during digestion. [1] The study looked a polyphenols and antioxidants found in pistachios. The study found that these polyphenols and antioxidants, which are also found in fruits and vegetables, are released during digestion, making them available to the body. The new findings, when considered in conjunction with earlier research that suggests dietary fat from pistachios may not be completely absorbed, is a win-win for those on the lookout for nutrient-rich snacks they can feel good about!

Pistachios –Antioxidants You Can See: Pistachios are the colorful nut, owing their green, yellow, and purple-red colors to the antioxidants and polyphenols found in the kernels and skins.

Fat in Pistachios May Not Be Completely Absorbed:[2] A preliminary study published in the January 2012 issue of British Journal of Nutrition suggests that the fat in pistachios may not be completely absorbed by the body. The small, randomized controlled-feeding study suggests we may consumer less calories per serving than originally thought. The research measured the energy value of pistachios by feeding 16 healthy adults the nuts as part of a controlled diet and calculating the energy value from differences in energy excretion during the dietary treatment timeframe. The resulting energy value of one 30‐gram serving of pistachios was 5 percent less than previous calculations.

The Snacking Bottom Line: Pistachios are a great-tasting, fun, and healthy snack that provides protein, fiber, and antioxidants. A naturally cholesterol-free food, 90-percent of the fat in pistachios is the healthy unsaturated type. A one-ounce serving of pistachios equals about 49 nuts, which is more nuts per serving than any other snack nut.

Be sure to color your plate with pistachios for a delicious and healthy snack!
