RESUMEN
Background Over the past decade, the rise of consumers following a gluten-free diet has increased greatly. The majority of people following a gluten-free diet have not been diagnosed with coeliac disease or gluten or wheat intolerance but believe it to be a health benefit.Aim To assess the differences between gluten-free and gluten-containing products with regards to the implications this might have on oral (and wider) health.Method In total, 50 purposively selected products (25 gluten-free and gluten-containing pairs) available to UK consumers, classified using the UK National Diet and Nutrition Survey food categories, were analysed using content analysis of food packaging. The European Union front-of-pack labelling system revealed the nutritional composition of each product, focusing on carbohydrates, sugars and energy. Cost and use of emotive language to market products was also assessed.Results A nutritional comparison of the 25 product pairings found that, on average, all gluten-free products contained more calories, total carbohydrates and total sugar. The majority of the gluten-free products were classified as 'confectionary' or 'baked goods,' emphasising that products primarily consisted of foods high in sugar. The average sugar per 100 g for each category of food ranged from 2.5-37.0 g/100 g (gluten-free) compared to 2.1-30 g/100 g (gluten-containing). All gluten-free products were considerably more expensive when compared with the conventional version; the average price difference ranged from £0.08 to £4.40.Conclusion This study emphasises the 'health halo' phenomena, where foods for special diets are regarded by consumers as healthy when in fact they are not. This results partly from the products being mainly high-sugar 'treats', which are not a core of the UK Eatwell Guide food-based dietary guidelines. As many people consuming gluten-free products in the UK do not need them from a medical perspective, this could have implications for oral and wider health. It is important that members of the dental team are aware of the possible implications of a gluten-free diet where it is not medically indicated, coupled with reliance on convenience foods.
RESUMEN
Aim Energy drinks are widely consumed worldwide and are recognised for their adverse health effects, usually due to their high caffeine content. However, little is known about their impact on oral and general health. The aim of this investigation was to review the most popular energy drinks sold in the UK, for their possible effect on oral health and contribution to obesity. Materials and methods Five drinks representing 75% of the UK energy drinks market were purposively selected (Lucozade, Red Bull, Monster, Rockstar and Relentless). pH and sugar content were measured and their ingredients reviewed in the context of oral and general health, focusing on dental caries and erosion and obesity. Results All five energy drinks investigated had pH values below the critical value (5.5) associated with dental erosion; the lowest pH was 2.72 (Lucozade) and the highest was 3.37 (Monster). The drinks also contained excessive amounts of free sugars, ranging from 25.5 g (Red Bull) to 69.2 g (Rockstar). Differences in sugar content were mainly explained by portion size. Other ingredients contained within the energy drinks, caffeine and various acids, are also linked to oral and general health. Conclusion Regular consumption of energy drinks could contribute to dental erosion and the development of obesity. Lucozade and Rockstar were found to potentially have the greatest impact on oral health and obesity. Achieving a healthy product by reformulation is highly unlikely due to the very high initial free sugar content. Thus, health professionals need to acknowledge the popularity of these products and help their clients to reduce their use. This is the first study which compares in detail the potential oral and general health consequences of overuse of a selection of energy drinks popular in the UK.

BACKGROUND: Novelty sweets resemble or can be used as toys, are brightly coloured, with striking imagery, and sold at pocket money prices. They encourage regular consumption as packaging can be resealed, leading to prolonged exposure of these high-sugar and low pH products to the oral tissues, risk factors for dental caries and erosion, respectively. AIM: To determine how children conceptualise novelty sweets and their motivations for buying and consuming them. DESIGN: Focus groups conducted using a brief schedule of open-ended questions, supported by novelty sweets used as prompts in the latter stages. Participants were school children (aged 9-10) from purposively selected state primary schools in Cardiff, UK. RESULTS: Key findings related to the routine nature of sweet eating; familiarity with and availability of novelty sweets; parental awareness and control; lack of awareness of health consequences; and the overall appeal of novelty sweets. CONCLUSIONS: Parents reported vagueness regarding consumption habits and permissiveness about any limits they set may have diluted the concept of treats. Flexible permissiveness to sweet buying applied to sweets of all kinds. Parents' reported lack of familiarity with novelty sweets combined with their low cost, easy availability, high sugar content, and acidity give cause for concern.

BACKGROUND: There is an increasing awareness that the provision of healthy food relies on the co-ordinated efforts of a number of diverse disciplines, not merely those traditionally linked with food. This paper documents the development of a food and health strategy, commissioned by the health alliance for the city of Cardiff, and focuses on the areas of sustainability, education and training as well as nutrition, food provision and food safety. OBJECTIVE: The aim of the strategy was to increase the uptake of a healthy, safe and sustainable diet for all those living in Cardiff. METHOD: The methodology included a rapid appraisal of food initiatives operating within the city, establishing a food and health strategy working group and the production of strategy documentation. Multi-agency collaboration and consultation were key components of the approach. RESULTS: As the strategy developed, seven action areas became apparent, including education and training, public sector procurement and rewarding excellence. These action areas were incorporated into seven 'action tables', which constitute the core of the strategy. The food and health strategy document was ratified by the Local Health Alliance board in August 2004. But, far greater benefits were realised as a consequence of setting up the strategy working group. Long before the document was written, the strategy process was operating as 'multidisciplinary public health in action'. CONCLUSION: The network that comprised the food and health strategy working group was already able to commence delivery of a more integrated approach to food and health within Cardiff.
