Alternative sugars: Sucralose

    Elaine Gardner, British Dietetic Association (BDA) Spokesperson, discusses the sugar content in sucralose and provides related oral health advice.


    What is it? Sucralose is an artificial sweetener. Although the name sucralose ends in -ose, it is not a sugar like fructose or sucrose, so the name is rather misleading. It is a modified form of ordinary sugar (sucrose). It is also known under the E number E955.

    Found in? It is commonly found in granular, liquid or mini-tablet form and sold under the trade name of 'Splenda' or as the individual yellow packets of Canderel (not other versions of Canderel as they contain different sweeteners).

    Sucralose-based products are in a broad range of lower-calorie foods, including table top sweeteners, fizzy drinks, chewing gum, baking mixes, breakfast cereals and salad dressings.

    Effect on general health: Sucralose itself contains no calories but because it is very sweet (approximately 600 times as sweet as sugar), sucralose in the granulated format is often mixed with other sweetening ingredients such as maltodextrin. This dilutes its intense sweetness and provides volume and texture. These, however, are not calorie-free, so a teaspoon contains about 2-4 calories. This is about 20% of the calories of sugar which the granulated product is intended to replace.

    The claim that 'sucralose has less of an impact on blood glucose than sugar' has been validated by the European Food Safety Authority.1

    Oral health impact: Sucralose has no effect on tooth decay (again validated by EFSA1). Any other sweetening ingredients included in the sucralose-based table top sweeteners are not harmful to teeth. Sucralose is commonly found in oral health products, such as chewing gum.

    Advice for patients: Sucralose is one of many artificial sweeteners that can be used as an alternative to sugar. These can be useful for weight reduction and for helping diabetics reduce their sugar intakes. Sucralose is not cariogenic, but, as always, good oral hygiene should be maintained.

    As part of a healthy diet, the population as a whole could also be encouraged to consider consuming fewer 'sweet snacks and drinks', rather than simply replacing those containing sugar with those containing artificial sweeteners.
