Sweeteners

Sweeteners are substances used to impart a sweet taste to foods and drinks. They can be naturally derived or synthetically produced. Many sweeteners are significantly sweeter than sucrose (table sugar), meaning smaller amounts are needed to achieve the same level of sweetness.

Sweeteners are added to foods and drinks to provide sweetness with fewer calories than sugar, or for people who need to manage their sugar intake. They are commonly found in 'diet' or 'sugar-free' versions of products such as soft drinks, confectionery, desserts, and chewing gum.

Sweeteners are authorised food additives in Great Britain and are listed on the Register of Food Additive Authorisations. For most people consuming typical amounts, authorised sweeteners are considered safe. Some research has explored links between sweetener consumption and gut microbiota or metabolic health, but evidence is mixed and further investigation is ongoing.
