You might think that based on a cursory anecdotal comparison, but studies show it is not true.
"Ultra-processed food staples dominate mainstream U.S. supermarkets. Americans more than Europeans forced to choose between health and cost" - https://www.medrxiv.org/content/10.1101/2024.02.16.24302894v...
"Price and availability trends by level of neighbourhood deprivation however, remain unclear; while studies in the US have tended to find differences between neighbourhoods and prices for availability of healthier food items, studies conducted in other countries have generally reported no association" - https://pmc.ncbi.nlm.nih.gov/articles/PMC3679513/
"The distribution of the FPro scores in the three stores shows a high degree of similarity: each store exhibits a monotonically increasing curve (Fig. 2a), indicating that minimally pro-cessed products (low FPro) represent a relatively small fraction of the inventory of grocery stores, the majority of the offerings being in the ultra-processed category (high FPro). Although less-processed items make up a smaller share of the overall inventory, they likely account for a proportionally larger portion of actual purchases, highlighting a discrepancy between sales data and available food options. Never-theless, systematic differences between stores emerge: Whole Foods offers a greater selection of minimally processed items and fewer ultra-processed options, whereas Target has a particularly high pro-portion of ultra-processed products (high FPro)." - https://www.nature.com/articles/s43016-024-01095-7.epdf?shar...
"“Our research shows that consumers prioritize taste and price when shopping for food, with nutrition coming in a distant third,” Balagtas said. “So the fact that consumers associate healthy eating with high costs and low taste is a challenge for food manufacturers and public health advocates.”" - https://ag.purdue.edu/news/2025/08/how-americans-make-health...
We have more ultraprocessed foods, fewer healthy options, the healthy options are more expensive, and their distribution is uneven (less healthy food depending on the store). Consumers' associations confirm this.
Meanwhile abroad there is less ultraprocessed food, the healthy food is more often subsidized (so it's cheaper), and healthy food distribution choices are more evenly distributed.
