“Recommendations about the use of low calorie sweeteners: where evidence meets policy. Report from a 2018 Expert Consensus Workshop”
A consensus workshop on low calorie sweeteners (LCS) was held in November 2018 where seventeen experts (the panel) discussed three themes identified as key to the science and policy of LCS: (1) weight management and glucose control; (2) consumption, safety and perception; (3) nutrition policy. The aims were to identify the reliable facts on LCS, suggest research gaps and propose future actions.
The panel agreed that the safety of LCS is demonstrated by a substantial body of evidence reviewed by regulatory experts and current levels of consumption, even for high users, are within agreed safety margins. However, better risk communication is needed. More emphasis is required on the role of LCS in helping people reduce their sugar and energy intake, which is a public health priority. Based on reviews of clinical evidence to date, the panel concluded that LCS can be beneficial for weight management when they are used to replace sugar in products consumed in the diet (without calorie substitution). The available evidence suggests no grounds for concerns about adverse effects of LCS on sweet preference, appetite or glucose control; indeed, LCS may improve diabetic control and dietary compliance. Limited data does not provide adequate evidence that LCS affects gut health at doses relevant to human use.
The panel identified research priorities, including collation of the totality of evidence on LCS and body weight control, monitoring and modelling of LCS intakes, impacts on sugar reduction and diet quality and developing effective communication strategies to foster informed choice. There is also a need to reconcile policy discrepancies between organisations and reduce regulatory hurdles that impede low energy product development and reformulation.

“Low calorie sweeteners as a means for weight and glycaemic control: outcomes of systematic reviews and meta-analyses”
Low calorie sweeteners (LCS) may be a useful tool to reduce caloric intake and control glucose response when consuming sweet foods and drinks. Still, several theories about untoward health effects of LCS acutely or in the long term exist, many of which are based on poor, little or no scientific documentation. A number of intervention studies in the past 3 decades have, however, shown that LCS do not stimulate appetite or increase BW, rather on the contrary. Thus, comprehensive meta-analyses from recent years have reported that the use of LCS may lead to reduced body weight relative to sugar (1). Lately, randomised controlled trials (RCTs) have also compared intake of LCS with water and changes in BW. Convincingly, a study in 303 overweight and obese individuals showed that subjects drinking LCS beverages maintained more than twice the weight loss than individuals drinking water after a 1-year behaviroual treatment programme, ie an improvement of weight control with LCS compared with water (2).
Another systematic review and meta-analyses of 29 randomised controlled trials investigated the role of aspartame, saccharin, steviosides and sucralose on glycemia. No rise in glucose was observed after LCS. Instead, glucose declined after LCS consumption (3). These findings have been confirmed by more recent short- and long term clinical studies (4, 5).
Currently, a new systematic review and meta-analysis of acute postprandial glycaemic and insulinemic response after acute exposure of LCS in randomised, controlled human intervention trials is being conducted (PROSPERO 2018 CRD42018099608). The results are expected to be presented at FENS 2019.
In a new Horizon-2020 project “SWEET” (www.sweetproject.eu, 2018 – 2023) we aim to dig further into the potential risks and benefits of sweeteners and sweetness enhancers (S&SEs). The focus in on health, obesity, safety and sustainability, while using a multidisciplinary approach. A main part of SWEET is a 2-y RCT, which will investigate the effect of prolonged use of S&SEs in a whole healthy diet approach (foods & drinks) on diet compliance, weight control and obesity related risk factors (eg glycemia, lipidemia) and safety (eg microbiota).

“Psychological and behavioural factors influencing consumers’ views and intakes of low calorie sweeteners”
Consumption of alternative sweeteners is increasing but there are concerns that sweeteners stimulate appetite, promote preference for sweet-tasting foods and lead to weight gain. Chronic dieters juggle two conflicting goals, hedonic goal of enjoyment of nice-tasting foods/beverages verses diet/weight control. Low Calorie Sweetened (LCS) beverages deliver sweetness (i.e. palatability) but without calories. Do LCS beverages help people to align conflicting goals (hedonic eating and successful weight control)? Our data show restrained eating patterns, body weight concerns, and positive beliefs about palatability and appetite control are key determinants of LCS beverage consumption. Consumption of LCS beverages may help consumers to align conflicting goals (hedonic eating and successful weight control). Frequent consumers may use LCS beverages as a successful strategy to control food intake when in a state of craving. Recent data show frequent consumer show an “attentional bias” towards their favourite LCS beverage (as opposed to a generalised bias to sweet-tasting drinks). This would suggest they don’t promote sweet preference per se. However, long term risks and benefits of LCS consumption will be determined in the ongoing SWITCH trial and SWEET project.

The ISA will also be present at FENS 2019 with an information booth in the conference’s exhibition area (booth number 1) in order to provide you with scientific materials and further information relating to low calorie sweeteners’ science.

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 updated ISA factsheets on the benefits of low calorie sweeteners.

Please do take the opportunity to also participate in our new 3-minute survey and enter into a prize draw to win a smartwatch to help you track your heart rate, sleep, activity and overall fitness level. Your feedback counts, therefore, we would be very interested to learn more about your scientific interests and views in relation to low calorie sweeteners and the ISA.

We therefore look forward to welcoming you all at the ISA information booth at FENS 2019 exhibition area during the whole duration of the congress, from 15th to 18th October 2019, to answer to any question you might have in relation to low calorie sweeteners’ use, benefits and role in the diet.

The FENS conference is held once every four years and is the premier European meeting within nutritional science for nutrition scientists and researchers, bringing together nutrition and health professionals from across Europe.

This year, the Nutrition Society (UK) in cooperation with the Nutrition Society Irish Section are hosting the 13th European Nutrition Conference, Federation of European Nutrition Societies (FENS) 2019 in Dublin, Ireland, taking place from 15th to 18th October 2019. In 2019, the conference will present European perspectives on ‘malnutrition in an obese world’.
