Non-sugar sweeteners - too sweet to be true?

Non-sugar sweeteners (NSSs) are low-calorie artificial alternatives to sugar, widely used in food, drinks, medicines and hygiene products. Their popularity has surged over recent decades, particularly for weight management and diabetes control. This paper examines the most commonly used NSSs in the United Kingdom, evaluating their chemical compositions and regulatory standards. Key findings reveal that NSSs may provide dental health benefits by reducing the risk of caries; however, their effects on metabolic health remain a topic of debate. While NSSs offer clear advantages for individuals seeking to limit sugar intake, research also points to possible long-term health implications, thus this paper highlights the importance of informed usage to minimise possible adverse effects, emphasising the need for balanced patient guidance on their consumption.
