Linoleic acid (LA), the primary polyunsaturated fatty acid (PUFA) in the US diet, is an essential fatty acid. LA is available from a wide variety of foods, although it is primarily sourced from plant seed oils. Individual-level data on demography and food and nutrient intake were acquired from the NHANES waves 1999-2000, 2001-2002, 2003-2004, 2005-2006, 2007-2008, 2009-2010, 2011-2012, and 2013-2014. Mean daily intake of (LA) was estimated for each survey wave overall, and by age, gender, educational attainment, race/ethnicity, and income to-poverty ratio. Linear temporal (1999-2014) trends in LA intake were estimated using univariate linear regression tests, with P < 0.05 and a two-tailed distribution. We found that US adults meet intake recommendation for LA and observed a trend of increasing intake of LA in the US overall and by sub-categories of age, sex, education, race/ethnicity, and income-to-poverty ratio.
