Wellness and well-being are terms found in a broad range of literature such as economics, social science, food marketing and general social commentary. These terms are often used in contexts that encompass mental, physical and emotional health as well as broader more esoteric aspects of life satisfaction such as happiness. The terms wellness and well-being are also used ubiquitously and variably in health practice. However, there is limited understanding about how they are used in the broader health promotion context and how consumers might interpret these terms in the context of food and nutrition messages. The primary aim of this paper is to review how the terms wellness and well-being are being used within a number of disciplines and describe implications for food choice. It is proposed that identifying the way these terms are used by key players in the food industry would enable more effective communication across sectors. This may assist in the collaborative development of public
health food and nutrition messages with a consistent meaning.
