Abstract

Humans run on a fuel called food.Yet economists and other social scientists rarely study what people eat.We provide simple evidence consistent with the existence of a link between the consumption of fruit and vegetables and high well-being.In cross-sectional data, happiness and mental health rise in an approximately dose-response way with the number of daily portions of fruit and vegetables.The pattern is remarkably robust to adjustment for a large number of other demographic, social and economic variables.Well-being peaks at approximately 7 portions per day.We document this relationship in three data sets, covering approximately 80,000 randomly selected British individuals, and for seven measures of well-being (life satisfaction, WEMWBS mental well-being, GHQ mental disorders, self-reported health, happiness, nervousness, and feeling low).Reverse causality and problems of confounding remain possible.We discuss the strengths and weaknesses of our analysis, how government policy-makers might wish to react to it, and what kinds of further research --especially randomized trials --would be valuable.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
