The International Sweeteners Association (ISA) is delighted to be supporting and to be present at the 12th EFAD Conference this year. Acknowledging the important role that dietitians play in raising awareness of, and educating people towards a healthy diet, the ISA proudly participates to the EFAD Conference for the fifth consecutive time.

The European Federation of the Associations of Dietitians (EFAD) is organising the 12th EFAD Conference this year in Berlin, Germany, on 1-2 November 2019. Themed as “Breaking Professional Boundaries”, the conference is bringing together dietitians across Europe to discuss the key role of dietitians in multidisciplinary teams, the importance of patient-centred care in developing new standards of dietetic care, as well as latest scientific evidence and the use of new technology in nutrition and dietetic research and care.

ISA activities at EFAD Conference 2019 include an ISA supported symposium with renowned experts who will present the latest evidence on the consumption of low calorie sweeteners as part of a healthy diet as well as an ISA information booth in the exhibition area during the whole duration of the congress.

Read more about the outcomes of the presentations at the ISA symposium in our press release “Low/no calorie sweeteners are safe and have a role to play in food reformulation” by clicking here or in the dedicated, more detailed, article available here.

The ISA information booth will host the ISA resources for healthcare professionals including newly developed materials presenting the latest research about low calorie sweeteners. By visiting the ISA booth, you will have the opportunity to receive a print copy of the new ISA booklet entitled “Low calorie sweeteners: Role and benefits – A guide to the science of low calorie sweeteners, as well as further resources for health professionals, including the recently created ISA infographics on benefits of low calorie sweeteners.

With November being the month dedicated to raising diabetes awareness, dietitians are invited to visit the ISA booth for a preview of the video developed for World Diabetes Day (WDD) 2019. This video and further online and printed materials for WDD 2019 are being developed by the ISA and with the scientific support of the EFAD’s European Specialist Dietetic Network (ESDN) for Diabetes. Delegates visiting the ISA booth will also have the opportunity to receive copies of printed infographics developed for previous editions of World Diabetes Day.

Furthermore, please do take the opportunity to participate in our new 5-minute survey and enter a prize draw to win a smart watch to help you track your heart rate, sleep, activity and overall fitness level. Your feedback counts, so your scientific interests and views in relation to low calorie sweeteners and the ISA are of highest importance to us.

We therefore look forward to welcoming you all at the ISA information booth at the EFAD 2019 exhibition area during the whole duration of the congress, to answer any question you might have in relation to low calorie sweeteners’ use, benefits and role in the diet.

With sugar reduction being a key public health objective, there is an increased interest from the scientific and consumer communities in the use of low calorie sweeteners as part of a healthy diet. In this context, the ISA is delighted to announce a highly interesting programme for the ISA-supported symposium at EFAD Conference 2019, which will take place on 1st November 2019, from 11h00 to 12h30pm (Room MOA 1-2).

During this session, invited speakers, who have conducted research in related areas, will discuss: 1) the evidence evaluated by regulatory authorities in the process of low calorie sweeteners’ safety assessment; 2) emerging science around diet, low calorie sweeteners and gut microbiota; and 3) recent recommendations about sweeteners’ intake in the context of obesity and diabetes.

Title of Presentation: Safety assessment and approval of low-calorie sweeteners: what type of evidence needs to be evaluated?
Speaker: Prof Dominique Parent Massin
Abstract: Risk assessment for food additives, including low calories sweeteners, is performed before authorisation by risk manager. Risk assessment is divided in four steps, hazard identification, hazard characterisation, exposure assessment, risk characterisation. Food additives authorised in EU under Regulation (EC) No 1333/2008 are currently being re-assessed by the European Food Safety Authority (EFSA). The deadline for the re-evaluation of a number of sweeteners by EFSA expires on 31st December 2020. However, their safety has been assessed several times by food safety agencies in the past. For some of them as aspartame, due to studies published in scientific literature, their assessment has been recently performed. Acceptable Daily Intakes (ADI) have been defined for most of them considering toxicological data. Exposure data have shown that ADI is not exceeded at maximum permitted level (MPL) in EU. Consequently, all low calories sweeteners are considered of not concern for the consumers. Risk assessment process and the latest risk assessment of each low-calorie sweeteners will be presented.

Title of Presentation: Low calorie sweeteners and gut microbiota: a review of animal and human studies
Speaker: Prof Ian Rowland
Abstract: The human colonic microbiota is a large and complex microbial community. Over 1000 bacterial species have been identified with about 160 being found in the gut of any individual. The size and diversity of the microbiota is reflected in extensive metabolic activities.
Observational studies comparing the faecal microbiotas of healthy subjects with those of patients, strongly suggest an association of gut microbiota composition and the aetiology and/or development of a range of gastrointestinal diseases and also a link with obesity and diabetes. However, the precise organisms involved are difficult to identify.
The interactions of low/no calorie sweeteners (LNCS) and gut microbiota has been the subject of numerous studies in laboratory animals and human subjects. LNCS are a structurally diverse group of compounds that have very different metabolic fates following consumption. Most (e.g. acesulfame K, saccharin, and sucralose) are not metabolized by gut bacteria. Stevia is a notable exception as its glycosidic forms are hydrolysed by the microbiota, releasing steviol, which is then absorbed intact without further bacterial metabolism.
LNCS are consumed at such low levels that they are unlikely to have a direct, clinically meaningful impact on the gut microbiota. Nevertheless, some studies on saccharin (mostly in laboratory animals) have shown effects on microbiota composition or metabolism, although only at very high doses above normal human consumption. Studies with other LNCS show either no, or inconsistent, effects on the microbiota, probably as a consequence of design issues and lack of adequate controls. Overall, the evidence indicates that LNCS have minimal impact on gut microbiota.

Title of Presentation: Recommendations about intake of sugars and low calorie sweeteners: impact on obesity and diabetes epidemics
Speaker: Dr Margaret Ashwell
Abstract: To help the public to reduce energy intake for their health, authorities have proposed limiting ‘free sugars’ to 10, or even 5 per cent of total energy intake. ‘Free sugars’ include all monosaccharides and disaccharides added to foods by the manufacturer, cook or consumer, plus sugars naturally present in honey, syrups and unsweetened fruit and vegetable juices and purees. Current intakes of ‘free sugars’ are well above these recommendations.
The use of low calorie sweeteners (LCS) is just one of the strategies to achieve these sugar goals. Groups of scientific experts have generated consensus statements, position papers, or other statements on LCS to show they are safe and effective. Many systematic reviews and meta-analyses have shown that LCS can help in reducing energy intake with implications for weight loss. Further, it is known that only small amounts of sustained weight loss are needed to reduce the risk of diabetes. It is now acknowledged that central obesity is a potent risk factor for diabetes and that the prevalence of central obesity is increasing rapidly. Fortunately central obesity can be detected by a simple anthropometric measure: the waist to height ratio (WHtR). A simple cut off WHtR 0.5 has been proposed which is universally applicable to children and adults. Prevention of central obesity is therefore essential if we are to have any impact on the epidemics of obesity and diabetes.
There is good evidence that the use of LCS can help to reduce obesity, including central obesity, or prevent it from increasing. Current UK government advice suggests low calorie drinks (i.e. those sweetened with LCS) as a suitable replacement for high sugar drinks. LCS consumption, as a means to limit ‘free sugar’ consumption, should be advocated more widely as one way to help to contain the epidemics of obesity and diabetes.
