pesticide risk messaging decreases fruit and vegetable consumption
In plain terms: Does warning people about pesticides make them eat less fruit and veg?
Part of: 🔍 pesticides in food
Three studies touch on this and none of them ran the experiment. For all the pesticide warning that exists, nobody appears to have tested whether it changes what people actually buy. The one real-world study found shoppers bought visibly stained tomatoes anyway, because they had no alternative.

How the studies fall
What the evidence shows
This claim matters because if residue warnings reduce how much fruit and veg people eat, the messaging could cost more health than the residues do. It is essentially untested. No study has experimentally manipulated a pesticide-risk message and measured downstream produce consumption or purchasing.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
