UK doctors are to prescribe fruit and vegetables to patients in danger of succumbing to heart disease. According to a report in The Guardian newspaper, up to 200 people in the north of England will be handed vouchers they can use to purchase produce. Health Links , a specialist service funded by local government and health authorities in a health action zone, is operating the scheme. The vouchers, worth £6 (US$8.60) per week, can be redeemed at participating Co-op stores for fresh, tinned, frozen or dried food.
