Both sleep disruption and a low intake of fruit and vegetables (FV) are associated with higher rates of premature death and chronic disease. This review looked at previous studies in order to determine whether there is a link between sleep and FV consumption. A recent meta-analysis found that shorter sleep duration is consistently associated with low fruit and vegetable intake in children, but in adults the association is less clear. Studies looking at the effect of sleep on FV intake had variable results. Tart cherries and kiwi fruits were the most commonly studied fruits for their effect on sleep measures. Observational studies tended to find that both short- and long-sleepers tend to eat less FV than those that sleep for 7-8 hours. A lot of evidence shows that people who go to sleep later (‘owls’) tend to consume unhealthier diets with lower intakes of FV than people who go to bed earlier (‘larks’). The researchers also looked at potential mechanisms for the association between sleep and FV intake. Polyphenols in FV may influence sleep by increasing neurotransmitters via the gut-brain axis, improving energy metabolism and through alterations in circadian rhythms and the CLOCK genes. Ways in which disrupted sleep may affect FV consumption included changes in hunger hormones, emotional stress and impaired decision making. With further research, interactions between sleep measures and FV consumption may be clarified and potentially reduce the burden of chronic diseases and premature deaths.
