Prominently displayed on the front page of noted nutrition advocate Jamie Oliver's web page is the claim that "20% of Australian children think pasta comes from animals".
A google search shows that this meme has spread quite a bit, almost certainly originating from that site.
However, I cannot find a source for this claim. The infographic contained on this page seems to be the primary point of distribution for this factoid (along with the claim that 27% of Australian kids believe that yogurt comes from plants), but the sources at the bottom of the infographic list a bunch of rather generic web pages, without linking to the specific report.
This version of the graphic includes a link to a PDF source, but the link isn't valid. I did find this PDF which is very similar to the broken link in that graphic, but there is no mention of any study, or even the claims cited" in that document.
Is the claim that 20% of children in Australia think pasta comes from animals, and 27% think yogurt comes from plants, backed by legitimate research?
