Doctors in the UK are to prescribe fruit and vegetables to potential victims of heart disease , UK newspaper The Guardian reports this week. Up to 200 people in the north-west of England are being given vouchers to exchange for produce as part of a health programme designed to kickstart changes in their diets and lifestyles. The adults are also offered advice on healthy cooking habits, fitness regimes and food shopping advice. The initiative is run by Health Links, a specialist service funded by local government and health authorities in a health action zone. It involves vouchers worth £6 a week being redeemed in local Co-op supermarket stores for fresh, tinned, frozen and dried food. Patients must have been referred by GPs or practice nurses to an exercise and lifestyle programme, which are becoming increasingly common in the UK. There is increasing evidence that eating five portions of fruit and veg a day could cut deaths from heart disease, cancer and strokes by about a fifth. Recent surveys in the UK, the newspaper reports, have suggested that one in five children eat none in a week and those that do eat an average of two portions a day. There is clearly room for improvement.
