Data are n (%; 95% CI) or mean (95% CI); all analyses account for survey design and sampling weights. NHANES=US National Health and Nutrition Examination Survey.
NHANES 2007–2010 adults (aged 18–65 years) who responded to questions about trying dietary guidance (MyPyramid or Food Guide Pyramid).
Potential changers are individuals who reported trying dietary guidance and were estimated to be likely to agree that humans contribute to climate change; these individuals comprised 16% (95% CI 15–17) of the sample.
We used χ2 tests to test for association between being a potential changer (or not) and each of the categorical demographic variables; we used Student's t test to test for differences between potential changers and non-changers on each of the consumption variables.
Commodity amounts of edible portion of the meats.
