The University of Toronto is unveiling new study findings that show incorporating pistachios into a meal results in delayed emptying of the stomach and blunting of the blood sugar curve, which may be of benefit to long term blood sugar control.

“Our study found that strategies, such as pairing pistachios with meals decrease blood sugar peaks after a meal, which may result in a lower risk for type 2 diabetes and coronary heart disease (CHD) risk,” said Dr. Cyril WC Kendall, University of Toronto.
Study Design and Highlights

The University of Toronto study included 15 men and women who fasted and then consumed three similar types of test meals in random order. The meals consisted of white bread plus two ounces of pistachios, white bread plus butter and cheese and the control meal was white bread. Blood samples were taken and subjective satiety measures were assessed over a three hour period in each of the test subjects.
The study found that:

  • The pistachios meal reduced peak blood sugar levels after a meal relative to white bread but was not different from the control meal.
  • Serum GIP was significantly raised by the pistachio and control meals relative to the white bread meal, indicating slower stomach emptying
  • At three hours, serum grehlin was significantly lower following the pistachio and control meals compared with the white bread meal, indicating a greater reduction in hunger.
  • Pistachios consumed with carbohydrate rich meals may blunt/moderate the blood sugar response after a meal or postprandial glycemic impact and thus may be of benefit in improving long term glycemic control.

Furthermore, in a study published in September 2009, pistachios were shown to have a dose-response effect on risk factors for heart disease, such as LDL cholesterol. Heart disease remains the leading cause of death among both men and women.   Pistachios are natural cholesterol-free snacks that contain just 1.5 grams of saturated fat and 13 grams of fat – the majority of which comes from monounsaturated fat.
