It is increasingly recognized, by individuals and health professional alike, that gardening and food growing is good for our health and wellbeing. While much of the evidence for these benefits is anecdotal, there is a large, and growing, body of evidence published in the scientific literature. The aim of this review is to draw together some of the published evidence so that it can be used to support decision making and to encourage health professionals to actively use gardening and food growing as part of the health care service provision.
