Abstract

Objective: Ultraprocessed foods (UPF), hyper-palatable foods (HPF), and high energy density (HED) foods may contribute to obesity risk. All have distinct definitions; however, it is unknown the degree to which they may identify overlapping or distinct foods. This study examined the availability of UPF, HPF, and HED foods in the US food system from 1988 to 2018 and the degree of distinction across definitions.

Methods: Four data sets representing the US food system (1988, 2001, 2006, 2018) from the US Department of Agriculture were analyzed. UPF were identified based on the extent of industrialized processing. HPF were identified using the standardized definition that specifies palatability-inducing nutrient combinations. HED was characterized as >2.0 kcal/g.

Results: Across years, 58% to 65% of foods were classified as UPF, 55% to 69% as HPF, and 37% to 47% as HED. Prevalence of UPF, HPF, and HED foods was higher in 2018 versus 1988 (p values < 0.001); HPF evidenced the largest increase (14%) and UPF evidenced the smallest (4%) over time. There was moderate to high overlap in foods (40%-70%) across definitions.

Conclusions: Together, UPF, HPF, and HED foods comprise most foods in the US food supply. Changes in availability varied across definitions, with substantial increases in HPF and HED and relative stability of UPF.
