I heard the USDA changed the nutrition information for pistachios. How did the nutrition facts change?
The USDA's National Nutrient Database issued a new release (Release 21) in September 2008; however the nutritional information for pistachios did not change. An article published in the Western Pistachio Association's Fall/Winter 2008 newsletter quoted a consultant who used a reduced serving size of 1 oz (28.35 grams), and that was the reason for the cited variation in caloric content.
The format and regulations concerning the Nutrition Facts statements on packaged food products, like pistachios, is governed by the FDA, not the USDA. FDA regulations have established a standard serving size (or Reference Amount for Customary Consumption) of 30g. In addition, the FDA has established rounding rules for the various nutrient amounts.
