“Around 41% of the study participants’ daily calories came from UPFs, a number close to the Australian average of 42% and far less than the 60% Americans consume.”

SINGLE SOURCE

While the claim mentions specific percentages for Australians (41-42%) and Americans (60%), the provided evidence for this claim consists of dictionary definitions of 'average' rather than the actual statistics. Only the original article (via The Independent's mention of the 60% US figure) provides this data, but it is not independently corroborated by the other provided search results.
