MedicalResearch.com Interview with: Professor Aubrey Sheiham
Emeritus Professor of Dental Public Health
Department of Epidemiology & Public Health,
University College London, WC1E 6BT. UK.
Medical Research: What are the main findings of the study?Prof Sheiham: There is a robust log-linear relationship of caries to sugar intakes from zero to 10% of sugars as a proportion of total energy intake. Furthermore our analyses showed that sugar intakes of 10%E sugars intake that is currently recommended as an upper limit for free sugars by the WHO and the Scientific Advisory Committee on Nutrition in England would induce a very costly burden of caries in most populations. Second, we found that free sugars* in the diet should make up no more than 3% of total energy intake. Above that level they cause a significant level of tooth decay across the lifecourse of most people in the developed world. Third, we were able to show that despite widescale fluoride use from both toothpastes and drinking water the mean numbers of decayed, missing and filled teeth (DMFT) and decayed and filled surfaces (DFS) for adults increased with sugar use despite the presence of fluoride.
*Free sugars are defined by the World Health Organisation Nutrition Guidance Adivisory Group as follows: “Free sugars include monosaccharides and disaccharides added to foods by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit concentrates.” (more…)
