ISA Symposium at the French Nutrition Days 2024 - International Sweeteners Association

The International Sweeteners Association (ISA) is delighted to support the 2024 French Nutrition Days (FR: Journées Francophones de Nutrition – JFN) that is being held in Strasbourg, France, from 4^th to 6^th December 2024.

On the occasion of JFN 2024, the ISA is organising a scientific symposium on Thursday 5 December 2024, at 12h15 – 13h45 CET, where French academic and scientific experts will talk about recent data on the safety and impact of low/no calorie sweeteners on appetite and on the physiology of sweet taste.

ABOUT THE ISA SCIENTIFIC SYMPOSIUM
There is a global consensus on the need to reduce excessive sugar consumption. This has led to an increased interest in the use of low/no calorie sweeteners as a strategy to reduce sugar intake, with a parallel assessment of the science on their safety and benefits. The Symposium proposed by the International Sweeteners Association (ISA) aims to inform delegates of the latest scientific developments on low/no calorie sweeteners and the physiology of sweet taste with the participation of three multidisciplinary speakers.

Dr. Stéphane Pirnay will review fundamental principles and protocols for the evaluation and re-evaluation of the safety of sweeteners by health authorities such as the Joint Scientific Expert Committee on Food Additives (JECFA) of the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) at the international level, as well as the European Food Safety Authority (EFSA) in Europe. He will also address the role of the European Commission, which is drafting – following the publication of a positive scientific opinion by EFSA – a proposal for the authorisation of the use of the sweetener in question in foods and beverages on the European market.

Dr Sandrine Chometton will review the state of knowledge on the modalities of the perception of sweet taste in humans. Although humans have an innate preference for sweetness, the physiology of sweet taste in humans is complex. Recent research has provided a better understanding of the mechanisms involved, and in particular the role of receptors, in the perception of sweet taste.

Dr Julie-Anne Nazare will present the latest data on the impact of low/no calorie sweetened foods and beverages on satiety and appetite, in particular those from the European SWEET project. This project, funded by the European Commission under Horizon 2020, aims to study the long-term benefits and potential risks of sweeteners and sweetness enhancers in the context of public health and safety, obesity and sustainability (https://sweetproject.eu/).

ABOUT JFN 2024
The French Nutrition Days – Journées Francophones de Nutrition (JFN) is an annual, interdisciplinary and interprofessional scientific meeting dedicated to nutrition that is jointly organized by the French Nutrition Society (FR: Société Française de Nutrition – SFN) and the French Society of Clinical Nutrition and Metabolism (FR: Société Francophone Nutrition Clinique et Métabolisme – SFNCM).

In recent years, the JFN has become an essential event in the field of nutrition, bringing together nearly 2,000 participants and experts in physiology, biology, food sciences and nutrition. This year, JFN 2024 is taking place at the Palais de la Musique et des Congrès in Strasbourg, France, from 4th to 6th December 2024.
