Benefits for people with diabetes

Low/no calorie sweeteners cause a lower rise in blood glucose levels after meals (post-prandially) if consumed instead of sugar and they do not otherwise affect blood glucose control or insulin secretion. The benefit of low/no calorie sweeteners on post-prandial glucose has also been recognised as a health claim by EFSA: Consumption of foods containing low/no calorie sweeteners instead of sugar induces a lower blood glucose rise after their consumption compared to sugar-containing foods1.

Low/no calorie sweeteners offer more “sweet” food choices to people with diabetes

Diabetes is one of the fastest growing health challenges of the 21st century, with the number of adults living with diabetes having more than tripled since 2000. Based on the latest figures released by the International Diabetes Federation (IDF) in 2021, it is estimated that globally 1 in 10 adults aged 20-79 years, a staggering 537 million people, are currently living with diabetes. If trends continue, IDF estimates that the number of adults living with diabetes worldwide will rise to 783 million by 2045. A further 1.2 million children and adolescents under the age of 20 live with type 1 diabetes.2

Low/no calorie sweeteners offer people with diabetes broader food choices by providing the pleasure of sweet taste without raising blood glucose.3,4 As low/no calorie sweeteners have no impact on insulin and blood sugar levels and do not provide calories, they can also have a role to play in weight loss and weight control for people with type 2 diabetes. 5-11

The role of low/no calorie sweeteners in diabetes

Over the last decade, numerous diabetes-related organisations worldwide, including the American Diabetes Association (ADA), the Diabetes and Nutrition Study Group of the European Association for the Study of Diabetes (EASD), Diabetes UK, Diabetes Canada, and the Latin-American Association of Diabetes (Asociación Latinoamericana de Diabetes – ALAD) have issued clinical practice and nutritional guidelines, position statements or consensus reports about the use of low/no calorie sweeteners in diabetes.

For example, a Position Statement on low/no calorie sweeteners (LNCS)6 by Diabetes UK concludes that: “LNCS are shown to be safe and they can be used as part of a strategy for adults and children in the management of weight and diabetes”.

Similarly, a consensus of the Latin-American Association of Diabetes (Asociación Latinoamericana de Diabetes (ALAD))7 acknowledges that the consumption of low/no calorie sweeteners is safe within the Acceptable Daily Intake (ADI) levels and further concludes that their use can have benefits in calorie reduction, weight loss and glucose control, when used to replace sugar in the context of a structured dietary plan.

A similar benefit is acknowledged by the Diabetes Canada Clinical Practice Guidelines Expert Committee who pointed out in the Clinical Practice Guidelines for the Prevention and Management of Diabetes in Canada 8 that the evidence from systematic reviews and meta-analyses of randomised controlled trials (RCTs), which give a better protection against bias, have shown a weight loss benefit when low/no calorie sweeteners are used to displace excess calories from added sugars.

More recently, in 2023, the Diabetes and Nutrition Study Group (DNSG) of the European Association for the Study of Diabetes (EASD) published updated European recommendations for the nutritional management of diabetes9 with the aim to provide health professionals with evidence-based guidelines. The European guidelines recommend the use of low/no calorie sweeteners to replace sugars in foods and beverages, while the intake of free or added sugars should be below 10% of total energy intake.9 The latest European recommendations on sweeteners are based on a series of systematic reviews and meta-analyses of RCTs10 and prospective cohort studies11 assessing the impact of low/no calorie sweetened beverages on cardiometabolic health in people with or at risk of developing diabetes. The two studies concluded that low/no calorie sweetened beverages, when replacing sugar-sweetened beverages, reduce body weight and cardiometabolic risk factors in people with or at risk for diabetes10 and are associated with reductions in the risk of obesity and cardiovascular outcomes in participants inclusive of people with diabetes, with reductions similar to those seen with the standard of care, water.”11

Finally, in the 2023 update of Medical Nutrition Therapy recommendations12, the American Diabetes Association (ADA) supported that: “The use of non-nutritive sweeteners as a replacement for sugar-sweetened products may reduce overall calorie and carbohydrate intake as long as there is not a compensatory increase in energy intake from other sources. There is evidence that low- and no-calorie sweetened beverages are a viable alternative to water.”
