Researchers set out to measure energy value of pistachios when eaten.
In the study, 16 men and women between the ages of 29 and 64 ate either 1.5 or 3 ounces of pistachios per day for 3 weeks as part of a controlled diet.
Energy value of pistachio nuts was calculated from differences in energy excretion during the different dietary treatments. The measured energy density of pistachios was found to be 22·6 kJ/g, which is 5 % less than the currently accepted.
