Science-backed low/no calorie sweeteners offer a safe way to enjoy sweetness while cutting sugar. With rising rates of obesity and non-communicable diseases, they can support healthier diets
Low/no calorie sweeteners provide sweet taste with minimal or no calories. They are used in foods and beverages to help reduce their sugar content. Supported by decades of scientific research and safety evaluations, low/no calorie sweeteners can be a practical tool for managing weight, assisting with glycemic control, and supporting oral health as part of a balanced diet.
Low/no calorie sweeteners are among the most thoroughly researched ingredients, with their safety confirmed by global food safety authorities like the European Food Safety Authority (EFSA), the U.S. Food and Drug Administration (FDA), and the Joint Expert Committee on Food Additives (JECFA) of FAO/WHO. Extensive studies demonstrate that consumption of approved sweeteners is safe for all population groups.
Sweetness is an integral part of the human diet and our appetite for sweet taste is innate. When health organisations worldwide recommend that free sugars intake should be reduced, managing dietary sweetness, including with the support of low/no calorie sweeteners, is critical from a nutritional and a public health perspective.

Brussels, 10 April 2026: The International Sweeteners Association (ISA) notes the publication of a new study in Frontiers in Nutrition examining the effects of sucralose and stevia under experimental conditions in mice. It is important to place these findings in the appropriate context while reaffirming that they do not challenge the established conclusions on the […]

Brussels, 8th January 2026: In response to the publication of the Dietary Guidelines for Americans 2025-2030, the International Sweeteners Association (ISA) highlights strong scientific evidence showing that low/no calorie sweeteners (LNCS) can support the important public health goal of sugar reduction. As acknowledged in the Scientific Foundation for the Dietary Guidelines for Americans, clinical and […]

Mexico City, 1st December 2025. With the participation of more than 20 international experts from Latin America, Europe, and North America, the 1st Latin American Scientific Forum on Low/No Calorie Sweeteners concluded in Mérida, Yucatán, marking a milestone in advancing scientific dialogue on nutrition, public health, and food policy in the region. Organized by the […]

Brussels, 19 November 2025: The International Sweeteners Association (ISA) responds to the recently published Lancet Series ‘Ultra-Processed Foods and Human Health’. There is currently no universally agreed definition of ‘Ultra-Processed Food’ (UPF) and it would be scientifically incorrect to automatically classify food and beverages containing low/no calorie sweeteners as UPFs. Low/no calorie sweeteners are amongst […]

Brussels, 9 October 2025: The International Sweeteners Association (ISA) would like to point to the limitations of the observational study presented at the United European Gastroenterology (UEG) Week 2025 that reported an association between beverages with low/no calorie sweeteners and liver disease. While observational studies can highlight population-level trends, they cannot establish causation. Importantly, individuals […]
Highlights: Analysis of three large prospective cohorts suggests that replacing sugar-sweetened beverages with diet drinks or water may help limit long-term weight gain. Increasing intake of low/no calorie sweetened beverages was not associated with weight gain, but rather, with slightly less weight gain over time. Findings are in line with evidence from randomised controlled trials […]
The new Dietary Guidelines for Americans, 2025–2030 promote a “real food” approach that prioritises minimally processed, nutrient-dense foods while discouraging consumption of highly processed products and food additives, including low/no calorie sweeteners. However, the recommendation regarding low/no calorie sweeteners is weakly substantiated and appears to be driven more by the ideology about “processing” than by a […]
What recent research reveals about low/no calorie sweeteners’ health effects and benefits Highlights Weight loss maintenance: A 2025 landmark clinical trial publication shows that incorporating low/no calorie sweeteners into a healthy, low-sugar diet can help people with overweight or obesity keep the lost weight off over one year. Low/no calorie sweeteners in diabetes: Recent position statements from […]
Highlights: Adults’ sweet taste preferences are remarkably stable. A six-month intervention with low, regular, or high exposure to sweet-tasting foods in the diet did not change how much people liked sweetness or how intensely they perceived it. Dietary sweetness exposure did not influence eating behaviour or health outcomes. No differences were found in calorie intake, […]
An overview of recent position statements on the use of low/no calorie sweeteners from professional nutrition and diabetes associations in Brazil and the UK Highlights: Low/no calorie sweeteners have long been part of the dietary toolbox for people with diabetes, offering the sweetness of sugar without its impact on blood glucose. However, controversy over their […]
Results from the SWEET Randomised Controlled Trial Highlights: A new landmark clinical trial shows that incorporating low/no calorie sweeteners into a healthy, low-sugar diet can help people with overweight or obesity in keeping the lost weight off over one year. The study also found beneficial shifts in gut microbiota composition associated with improved metabolic function, which may […]
