British Nutrition Foundation Conference Addresses Consumer Confusion About Low Calorie Sweeteners, England

Evidence on the safety and health effects of low calorie sweeteners is being debated by leading experts at a British Nutrition Foundation (BNF)

conference, The Science of Low Calorie Sweeteners - Separating Fact from Fiction, in London today.

The results of research in over 2,000 adults, conducted by YouGov on behalf of BNF, has been launched at the conference, showing that although only 10% of adults think low calorie sweeteners were safe for everyone, 82% appear to regularly consume products that typically contain sweeteners. The research also shows that the majority of consumers view nutritionists, dietitians and other health professionals (26%), and the Food Standards Agency (21%), as the most reliable sources of information about food . The conference aims to provide these health professionals, as well as food and nutrition journalists, with information to enable them to educate consumers' choices effectively in relation to low calorie sweeteners.

Sara Stanner, Science Programme Manager at the BNF explained: "Our research shows that some consumers have questions about sweeteners and their role in the diet. It also indicates that health advisers are considered to be the most reliable source of information on food. Health professionals, armed with the facts, can help to get accurate information to consumers and dispel some of the myths."

The BNF conference line-up included eminent experts from across the field of nutrition and health. Prof Adam Drewnowski from the University of Washington Centre for Obesity Research, presented the science behind our innate desire for sweet tastes. He outlined evidence on the physiological and behavioural effects of low calorie sweeteners, which supply the sweet taste that we are programmed to prefer while not providing energy,

Dr France Bellisle, from the Faculty of Medicine at Universite Laval, Quebec, developed this theme, discussing the effects of low calorie sweeteners on appetite and satiety. Early reports on low calorie sweeteners suggested that providing a sweet taste without calories could actually stimulate appetite. However, studies that have tested this in humans have not borne out this theory.

Prof Nick Finer, from the Department of Medicine, University College London, outlined evidence for the effectiveness of low calorie sweeteners in weight control and diabetes. He emphasised the complex and contradictory nature of the literature relating to choice of low calorie sweeteners and their effect on body weight, and whether people who are overweight or obese are more likely to choose these products.

With regards to the safety of low calorie sweeteners, Prof Andrew Renwick, from the School of Medicine, University of Southampton, described the process of safety testing for low calorie sweeteners and how regulatory authorities decide on the acceptable daily intake figures governing the use of these products in foods and drinks.

The conference concluded with a panel discussion on the science behind the headlines, with questions from the audience being directed at panelists including Prof Tom Sanders from Kings College London, Catherine Collins of St George's Hospital NHS Trust, and Brigid McKevith of Cereal Partners UK, together with the aforementioned conference speakers.

Stanner concluded: "We hope that the conference will help to clarify the evidence so that health professionals can effectively help consumers make informed decisions about their use of low calorie sweeteners."
