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.
Assessment of the safety of nutrients presents a challenge different from that posed by the assessment of other chemicals in food such as additives or contaminants. Because nutrients are essential, a dose-response relation exists at both ends of the intake range, separated by a safe range of intake that reflects normal homeostatic processes. The safe intake may not be the same for all population groups and life stages. The size of the safe intake range for each nutrient will vary and in a few cases may be very small. Certain nutrients such as vitamin A and manganese have known and potentially serious adverse effects at high intakes, whereas others such as iron or vitamin C may have more minor adverse effects that are readily reversible and may only be associated with supplement intake. The risk of harm occurring from taking dietary supplements will depend on the safe intake range of the nutrient concerned, the susceptibility of the individual, and the likely intake of the same nutrient from other supplements or the rest of the diet. In many cases, the available database for the safety of nutrients is very limited because the studies, where available, were not designed to assess adverse effects but may have detected problems when they occurred. Further information on the safety of nutrients could be obtained through careful experimental design.
Recent recalls of lead-contaminated jewelry and the death of a Minnesota child by lead poisoning after swallowing a jewelry charm have highlighted the hazards of leaded jewelry to children. We sought to determine the extent of lead contamination in inexpensive, imported jewelry available in United States retail stores. A total of 139 jewelry items were purchased from ten retail store chains in five different geographic locations. Samples were digested in nitric acid followed by atomic absorption analysis. Accessibility of lead was analyzed by leaching a subset of heavily leaded samples in 0.07 M hydrochloric acid. Almost half (42.6%) of the items assayed were heavily leaded, exceeding 80% lead by weight. Average lead content for all items tested was 44.0%, and one or more heavily leaded items were found in samples from each retail store and each geographic location. Six of ten samples tested for leachability of lead exceeded the US Consumer Product Safety Commission guidelines of 175 microg accessible lead. Our results show that much inexpensive children's and costume jewelry imported and sold in the US is heavily leaded. Given the high neurotoxicity of lead to young children, inexpensive jewelry items pose a potential yet avoidable threat to children's health.
