RESUMO
One of the most recent food trends is the quest for products that provide 'sustained energy'; a term that is garnering considerable attention within the marketplace. Often, 'sustained energy' health claims are based on a food's post-prandial glycaemic response. However, are generalised health claims regarding 'sustained energy' valid when only supported by glycaemic response data? Without context, the short answer is: probably not. Health claims that link sustained energy to a glycaemic response, or any other attribute of a food or diet, require context to ensure that the public correctly interprets and experiences the claimed effect and is not misled in their quest for healthy foods that impose the desired physiological benefit.

The recent proliferation of standards and labels for organic, fair-trade, locally produced, and healthy food products risks creating confusion among consumers. This study presents a standardized approach to developing a comprehensive sustainability label that incorporates ecological, economic, and social values. The methodology is based on an extension of modular life-cycle assessment to non-environmental sustainability criteria. Interviews with a wide range of experts (n=65) and a consumer survey (n=233) were conducted to analyze the feasibility and potential effectiveness of the approach. Responses indicated that a comprehensive sustainability label could considerably influence consumption patterns and facilitate cross-product comparisons.
