A recent report on diet and oral health by the British Nutrition Foundation reviews the anatomy, microbiology and pathology of a number of oral diseases including dental caries, tooth-wear, oral cancer, periodontal disease and enamel defects. The role of nutritional factors in the aetiology and prevention of these oral diseases is discussed. The report states that improvements in the levels of caries in the UK are halting and remain unacceptably high in some 'at risk groups'--including the socially deprived. It states that a two-pronged attack, i.e. reduced frequency of consumption of sugary foods and use of fluoride is necessary to address the problem. To address the increased prevalence of oral cancer avoiding tobacco, limiting alcohol and increasing fruit and vegetable consumption are recommended. Recommendations for approaches to improve oral health are made for health authorities, industry, schools and health professionals and it is recommended that the Government make adequate resources available to improve oral health preventive strategies.
