Intake of pistachio may improve cardiovascular risk factors in adults with type 2 diabetes say study

Study suggests that intake of pistachio may improve cardiovascular risk factors in adults with type 2 diabetes. 30 adults (40 to 74 years) with type 2 diabetes in a randomized, crossover, controlled feeding study. 

After a 2‐week run‐in period, participants consumed a low‐fat control diet (27% fat) containing low‐fat/high‐carbohydrate snacks and a moderate‐fat diet (33% fat) containing pistachios (20% of total energy) for 4 weeks each, separated by a 2‐week washout. Following each diet period,  BP, systemic hemodynamics, and heart rate variability at rest and during acute mental stress, and, in a subset of participants, 24‐hour ambulatory BP was assessed. BP at rest and during stress did not differ between treatments. The pistachio diet significantly reduced total peripheral resistance, increased cardiac output, and improved some measures of heart rate variability. Systolic ambulatory BP was significantly reduced, with the greatest reduction observed during sleep.
