We aimed to assess 1) the association of area- and household-level housing costs with household-level food purchasing characteristics and 2) explore the moderating effect of Supplemental Nutrition Assistance Program (SNAP) participation and SNAP purchasing power in these associations. Household-level data come from the National Household Food Acquisition and Purchase Survey (FoodAPS; n = 3707 households), including the outcomes analyzed: spending per 500 kcal, total kcal purchased, and quality of food purchased. Exposures include being housing-cost burdened (i.e., spending &gt;30 % of monthly income on housing) and the U.S. Department of Housing and Urban Development's Small Area Fair Market Rent (FMR) as a measure of area-level (i.e., zip code in metro areas, county in non-metro areas) housing costs. Moderators were SNAP participation and SNAP purchasing power (i.e., the ratio of the max SNAP benefit amount to the local cost of the Thrifty Food Plan). We ran linear regression models adjusted for household and area-level covariates. In areas with low SNAP purchasing power, a higher FMR was associated with higher spending per 500 kcal for SNAP participants (B = 0.039, 95 %CI = 0.009,0.069), eligible non-SNAP participants (B = 0.030, 95 %CI = 0.012,0.048), and ineligible non-SNAP participants (B = 0.020, 95 %CI = 0.004,0.036). In areas with high SNAP purchasing power, a higher FMR was associated with lower total kcal purchased for SNAP participants (B = −0.084, 95 %CI = −0.141,-0.028).

Some have proposed that these substitutes might soon replace animal-based meats based on the supposition that price, taste and convenience (PTC) are the primary drivers of food choice. Thus, it is conjectured that if a plant-based meat analogue matches (or exceeds) its animal-based counterpart in terms of PTC, a majority of consumption would shift from animal-based to plant-based. However, this conjecture has received little critical attention. To fill this gap, we will review evidence testing the PTC conjecture, including cross-sectional surveys, hypothetical discrete choice experiments, a field experiment and commercial case studies. Ultimately, given current consumer preferences, we do not find support for the PTC conjecture.
