Researchers seek participants for study on pistachios and diabetes

A Vascular Health Intervention Lab study will examine the cardiovascular changes in people with type 2 diabetes caused by eating different diets, including a diet containing pistachios. This study may provide important information about the health effects of adding pistachios to the diet.

The study is approximately 12-14 weeks long and consists of a two week run-in diet. This is followed by two, four-week diet periods with a two week washout in between. During the run-in and diet periods, all of the subjects' food for the day will be provided. Caffeine consumption will be limited to 40 ounces a day and alcohol consumption limited to two drinks per week. It is vital to the study that the participants are able to adhere to the diet plan and eat one meal a day Monday through Friday at the GCRC.

We are looking for men and postmenopausal women between the ages of 30 and 70 who have been diagnosed with type II diabetes more than six months prior to entering the study. Subjects must be relatively healthy, nonsmokers who have no other chronic diseases besides diabetes. Other exclusion criteria include taking insulin or blood pressure-lowering medications. After the screening exam, participants will make nine visits to the GCRC on campus and undergo heart rate and blood pressure monitoring, stress tasks like mental arithmetic, oral glucose tolerance tests, fasting blood draws, and a vascular ultrasound. Vascular ultrasound involves inflating a blood pressure cuff on the forearm for five minutes to measure artery health.

All of the tests pose minimal risk and subjects will be paid $500 for the completion of the study. For more information, contact Kate Sauder at kaf22@psu.edu or 814-863-0926.
