| Plenty of replacements exist already. There are older artificial sweeteners like aspartame, saccharin and sucralose - typically used in diet drinks - and newer natural sweeteners such as stevia and monk fruit extracted from plants (the latter isn't yet approved, external as a food item in the UK or EU). Many times sweeter than sugar, they require only tiny amounts. | |
| There are also polyols or sugar alcohols - erythritol particularly has gained traction in recent years. | There are also polyols or sugar alcohols - erythritol particularly has gained traction in recent years. |

| Other new bulking sweeteners are emerging too. In the UK, The Supplant Company has developed a low calorie, low glycemic response product which is mildly sweet.

| Physically modified in this way effectively makes the sugar sweeter: it dissolves more easily in the mouth, so less is required for the same taste. Incredo's customers include US bulk chocolate manufacturer Blommer. | Physically modified in this way effectively makes the sugar sweeter: it dissolves more easily in the mouth, so less is required for the same taste.
