摘要:Dear Editor,We thank Drs. Scarborough and Rayner for their comments regarding our recent paper on nutrient density of beverages in relation to climate impact (1). We hope that they do not disagree with the central premise of our research: that calculations of greenhouse gas emissions from the food system ought to take nutrient density of foods or beverages into account. The desirable food products are those that are sustainable but also have maximum nutritional value.(Published: 19 November 2010)Citation: Food & Nutrition Research 2010. 54: 5732 - DOI: 10.3402/fnr.v54i0.5732
