Fresh and Lean Beef Consumption in Relation to Nutrient Intakes and Diet Quality Among U.S. Adults, 2005–2016 (P18-057-19)

Abstract

ObjectivesThis study assessed the influence of beef consumption on nutrient intakes and diet quality among U.S. adults. MethodsNationally-representative sample (N = 27,117) from the National Health and Nutrition Examination Survey (NHANES) 2005–2016 waves were analyzed. First-difference estimator addressed confounding bias from time-invariant unobservables (e.g., eating habits, taste preferences) by using within-individual variations in beef consumption between 2 nonconsecutive 24-hour dietary recalls. ResultsApproximately 53.6%, 11.6%, and 6.7% of American adults consumed beef, fresh beef, lean beef, and fresh lean beef, respectively. An increase in lean beef and fresh lean beef consumption by one ounce-equivalent per day was associated with an increase in the Health Eating Index-2010 score by 0.20 (95% CI = 0.10, 0.29) and 0.29 (95% CI = 0.03, 0.55), respectively. Prevalence of beef, fresh beef, lean beef, and fresh lean beef consumption differed by sex, age, race/ethnicity, education level, and obesity status. An increase in beef, fresh beef, lean beef, and fresh lean beef consumption by one ounce-equivalent per day was found to be associated with an increase in intakes of total energy by 46.1, 39.6, 34.3, and 23.3 kcal, protein by 5.0, 4.1, 4.9, and 4.2 g, sodium by 66.6, 63.4, 35.8, and 39.1 mg, choline by 18.9, 18.1, 19.4, and 18.9 mg, iron by 0.6, 0.6, 0.5, and 0.5 mg, selenium by 3.8, 3.4, 3.6, and 3.8 μg, zinc by 1.4, 1.2, 1.3, and 1.1 mg, phosphorus by 37.1, 37.5, 32.4, and 34.4 mg, vitamin B2 by 0.03, 0.05, 0.02, and 0.04 mg, vitamin B3 by 0.9, 0.6, 0.9, and 0.6 mg, and vitamin B6 by 0.1, 0.06, 0.1, and 0.07 mg, respectively. An increase in beef, fresh beef, and lean beef consumption by one ounce-equivalent per day was found to be associated with an increase in daily intakes of saturated fat by 0.9, 0.8, and 0.6 g, and vitamin B12 by 0.4, 0.3, and 0.4 μg, respectively. No association linking fresh lean beef consumption with daily intakes of saturated fat and vitamin B12 was identified. ConclusionsBeef consumers are advised to increase their share of fresh and lean beef over total beef intake in an effort to maximize their nutritional gains from beef consumption while minimize the resultant increase in energy, saturated fat, and sodium intake.
