The December 2011 issue of the Nutrition Bulletin is a Special Issue: Achieving a healthy sustainable diet: an integrated approach, guest edited by our own Helen Riley. This issue presents evidence and arguments from all sides of the sustainability debate, in relation to food production and supply, as well as consumption patterns.  We are delighted to have the ‘Foreword’ written by the Chief Scientific Advisor to the Government, Professor Sir John Beddington, while the issue itself contains a compilation of scientific papers prepared by eminent and respected spokespeople from within government, horticulture, livestock, fisheries, food manufacturing, retail, and the food service industry.  It also examines public health implications, presents the consumer perspective, and discusses food waste and seasonal foods.
