Enrich Your Love Life With Pistachios

Preliminary Research Suggests That Eating Pistachios May Improve Symptoms of Erectile Dysfunction in Men

FRESNO, CA--(Marketwire - Feb 1, 2012) - Pistachios are making noise in the health and nutrition spectrum as 'The Love Nut' based on a recent Turkish study which demonstrated that men with erectile dysfunction (ED) who added pistachios to their diet saw improvement in erectile function.1 This study supports the growing body of evidence on the health benefits of pistachios, including heart and blood vessel health, weight management and blood sugar control.

The study, which was conducted by Dr. M. Aldemir at Atatürk Teaching and Research Hospital in Ankara, Turkey, and published in the January 2011 issue of The International Journal of Impotence Research, consisted of 17 married men (ranging from 38-59 years of age) who had experienced ED for at least 12 months. All patients were evaluated using medical history and sexual history with the International Index of Erectile Function (IIEF), a physical examination and routine blood analysis. Each man ate 100 grams (about 3.5 ounces) of pistachio nuts per day for three weeks. The subjects were asked to maintain their regular daily dietary intake, physical activity and other lifestyle habits. Study participants saw a significant improvement on IIEF scores, which measure such things as orgasmic function, sexual desire and sexual intercourse satisfaction. There was also improvement in penile ultrasound measures, but the difference was not statistically significant. Participants also had a significant reduction in total blood cholesterol and LDL ("bad") cholesterol, and a significant increase in HDL ("good") cholesterol. The authors speculate that several attributes of pistachios may have contributed to both the erectile function and blood lipid improvements, including their healthy fats, natural plant sterols, protein, fiber and antioxidants.

"Pistachios have been considered an aphrodisiac in some folklore," said Dr. Thomas W. Hopkins, M.D., internal medicine specialist and former member of the National Advisory Panel for Erectile Dysfunction. "To my knowledge, this is the first study that lends support for this belief. We know that pistachios can improve blood cholesterol levels and can be part of a successful weight management program. Men, especially, may want to consider substituting pistachios for other snack foods."

Pistachio nuts are a natural health food, full of nutrients. The U.S. Food and Drug Administration recognize that tree nuts, including pistachios, can be part of a heart-healthy diet. Pistachios have more nuts per serving, 49, than any other tree nut, and contain only 160 calories in this serving size.

The American Pistachio Growers was not involved in this study.

American Pistachio Growers is a voluntary trade association representing members who are pistachio growers, processors and industry partners in California, Arizona and New Mexico. These states represent 100% of the domestic commercial pistachio production. APG pistachios are the "Official Snack" of both USA Water Polo and Miss California. For more information, visit
