Onderzoek: Etiket van levensmiddelen kan andere effecten hebben in verschillende sociaaleconomische groepen

Researchers at King's College London UK aimed to investigate the likelihood of paradoxical effects of nutritional labelling on energy intake. Participants attended a cinema where they were randomised to receive their selected flavour of popcorn with one of three labels: a green low-fat label, a red high-fat label or no label.
Contrary to predictions neither BMI nor weight concern moderated the effect of label on consumption. There was a three-way interaction between low-fat label, weight concern and socioeconomic status (SES). They concluded that nutritional labelling may have different effects in different socioeconomic groups. An article about the research is published in Appetite.
