Low calorie sweeteners

Last Updated : 15 October 2012

During the 19th European Congress on Obesity, organised by The European Association for the Study of Obesity, which took place in France from May 9th to 12th 2012, the topic of low calorie sweeteners was addressed. Low calorie sweeteners are many times sweeter than sugar and deliver very few calories because they are used in tiny amounts. They are used to replace sugar in a wide range of sugar-free and low-calorie foods and drinks and most are also available as table top sweeteners. Low calorie foods and drinks contribute to people's weight management efforts, but it is important that they form part of a balanced diet and healthy lifestyle which includes regular physical activity.

In this podcast interview, Dr. Josephine Wills, Director General of EUFIC, interviewed two speakers from the U.S.A. who participated in the symposium ‘Low calorie sweeteners – translating the science into practical recommendations’, Professor Richard Mattes from Purdue University and Dr. Julie Mennella from the Monell Chemical Senses Center in Philadelphia.
