New Research Unveils That Pistachios May Lower Risk of Type 2 Diabetes by Improving Blood Sugar Levels
The new study led by researcher Dr. Cyril WC Kendall from University of Toronto’s Department of Nutritional Sciences and funded by the Western Pistachio Association, looked at the effects of pistachios on glucose and insulin responses and on its influence on satiety, or level of fullness. Previous studies have examined pistachios’ effect on glucose levels which showed a dose response effect on blood sugar levels. In order to further assess pistachios’ impact on health, Dr. Kendall and his team studied the effect of pistachios on serum glucose, insulin levels and gut satiety hormone responses.
“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,
Study Design and Highlights
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.

Pistachios and Other Nuts Lower HbA1C in Persons with Type 2 Diabetes
This new pistachio study ties into another study being presented today by Dr.
More recently, interest has grown in the potential value of including nuts in the diets of individuals with diabetes. To date, there have been few studies that have assessed the effect of nuts on glycemic control. Dr. Kendall’s aim was to assess the effect of two doses of mixed nuts on serum lipids and glycemic control in type 2 diabetics.
The study showed that nuts improved blood glucose control in people with diabetes and significantly lowered HbA1C (a marker of blood sugar control over the previous three months) and LDL cholesterol levels. The study concluded that mixed nuts may improve serum lipids and glycemic control in individuals with type 2 diabetes.
“Overall, nut consumption is associated with reduced risk of cardiovascular disease and better long term control of blood sugar in persons with type 2 diabetes,” said Dr.
General Nutrition Facts About Pistachios
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. A one-ounce serving of pistachios equals 49 nuts – more per serving than any other snack nut. One serving of pistachios has as much potassium as a small banana and three grams of fiber making it a nutritious snack choice or ingredient to incorporate into your daily diet.
