Is there any link between pistachios and diabetes?

Research has indicated that pistachios reduce levels of glucose and insulin as well as other metrics of insulin resistance, notes the American Diabetes Association. The pistachio regimen also improved other measurements connected to diabetes and heart risk.

The implications of this study are that consuming a handful of pistachios each day, in conjunction with other elements of a healthy diet, helps some prediabetic people improve so that they do not develop Type 2 diabetes or other diseases, according to the American Diabetes Association. However, the high caloric content in nuts means that portions must be controlled to prevent weight gain.
