Pistachios are one of the lowest calorie nuts with 160 calories per 30 gm serving (approximately 1 ounce). Also pistachios are cardio-supportive when 1.5 and 3 ounces of pistachios was included in the diet. Pistachios support weight management and are a wise snack. They are a good source of proteins and fiber. Snacking on pistachios supports the body mass index (BMI) goals and also supports heart health, according to researchers at the University of California - Los Angeles.
The fat found in pistachios does not get completely absorbed from the gastrointestinal tract, which indicates that pistachios might actually contain fewer calories per serving than previously thought. This research was conducted by the Agricultural Research Service (ARS) of the United States Department of Agriculture (USDA). 16 healthy adults were part of the study. They were given one 30gm serving of pistachios. The energy value from differences in energy excretion during the dietary treatment timeframe was calculated which showed that the energy value of one 30gm serving was 5.9% less than previous calculations.
