Pistachios grown and marketed by the American Pistachio Growers, Fresno, Calif., can now carry the American Heart Association’s Heart-Check mark.

The certification mark can be used on packages and promotional materials for roasted and salted pistachios both in and out of the shell, as well as roasted, unsalted pistachios, according to a news release from APG.

Judy Hirigoyen, APG’s director of global marketing, said in the release that the approval from the American Heart Association to use the Heart-Check mark confirms what pistachio growers have been saying for a long time: The cholesterol-free nuts can promote better health in the context of an overall healthy diet.

One serving of pistachios, which is about 45 nuts, contains vitamins, minerals, 7 grams of monounsaturated fats and four grams of polyunsaturated fats, according to the APG.

The American Heart Association has been promoting healthy eating habits by awarding its Heart-Check mark to approved foods since 1995.
