Deciphering the multifaceted effects of artificial sweeteners on body health and metabolic functions: a comprehensive review and future perspectives.

AbstractAs the rates of chronic diseases such as obesity and diabetes rise worldwide, there is a growing demand for low-calorie or no-calorie sweeteners to reduce sugar intake without sacrificing the sweetness of foods and beverages. Artificial sweeteners have become indispensable as substitutes for sugar due to their high sweetening power and low impact on blood sugar levels and are used in a variety of low-calorie foods and beverages. Although artificial sweeteners offer an alternative for reducing sugar intake while maintaining sweetness, research into their long-term health effects, particularly at high doses, is ongoing, further scientific research and regulatory review are needed to clarify these potential health risks. This article reviews the latest research on the health effects of artificial sweeteners, based on recent studies, introduces the classification, performance, and safety standards for artificial sweeteners, analyses their potential harms to the nervous, immune, and circulatory systems, reproductive system, as well as their effects on gut microbiota, liver function, cancer, diabetes, and obesity. In addition, consumer perceptions of artificial sweeteners and future research directions are discussed, providing insights into current research controversies and knowledge gaps, as well as the health research and market application of artificial sweeteners.
