Parkinson's disease is an age‐related brain disease which is currently incurable. The long period during which damage occurs but symptoms are not evident is a focus of research with an aim to finding ways of reducing damage. This paper is the third in a series of diet and PD and covers the evidence for a role of fruit, vegetables and grains in the development of PD. Evidence is not conclusive but suggests that increasing the consumption of fruit, vegetables and grains may reduce the incidence of PD. A small number of studies have found a positive association between fruit and vegetables and PD but this may be due to chemical contamination. There is a need for further research to be carried out, preferably as part of a large ongoing study, rather than using retospective data, with its inherent bias.
