Abstract

Many fresh pork products, in particular, fresh lean pork products, are nutrient-dense sources of protein and several other nutrients. The purpose of this study was to estimate nutritional contributions of fresh and fresh lean pork to adults' diets in the United States. Mean total nutrient intakes by fresh and fresh lean pork consumers on a day of recall were compared with intakes by nonconsumers to test the hypothesis that overall nutrient intakes by consumers were comparable with or better as compared with intakes by nonconsumers. Intakes were assessed using the National Health and Nutrition Examination Survey 2003 to 2006. Based on 1 day of dietary intake, 10% of adults consumed fresh pork, and 4% consumed fresh lean pork. Among consumers, fresh and fresh lean pork contributed 16% and 9%, respectively, of total fat and accounted for 23% to 31% of total protein, cholesterol, selenium, and thiamin intake. Fresh and fresh lean pork also accounted for 11% to 19% of total saturated fat, phosphorus, potassium, riboflavin, niacin, vitamin B(6), and vitamin B(12) in the diets of consumers and contributed 21% and 16%, respectively, of total zinc. Diets including fresh or fresh lean pork provided higher energy-adjusted amounts of protein, selenium, thiamin, and vitamin B(6) as compared with diets of adults not consuming fresh pork (P < .05) and provided comparable amounts of fat and saturated fat. Consumption of lean cuts of fresh pork is consistent with dietary guidance, and selection of fresh lean pork products by current nonconsumers could increase dietary variety without adversely affecting nutrient intake.
