The DHSS recently reported on school children's food intakes (1). Although the type of fat eaten is clearly an important issue, the DHSS study did not analyse the fat intake for its saturated and essential fatty acid content. We have explored the intakes of the children for fibre, sugar and saturated fats as well as additional vitamins and trace elements, not reported by the DHSS. The data from the DHSS survey was presented as a summary of the main food types eaten. They aggregated some food groups e.g. meat and meat products, fish and fish products, cakes and biscuits. While this approach might make little difference to protein intakes, it may be expected to make a difference to fat and essential fatty acid intakes. We have re-analyzed the childrens food intakes keeping within the confines of the food groups reported. We had to rely on certain assumptions about the nature of an 'average' diet; we therefore explored the possibility that our assumption of an average diet was incorrect and examined a worse and a better situation to define how much the nutrient intake varied. The result of the analyses illustrate an important principle in the context of the present concern for food and health. The only way in which we could satisfy NACNE and COMA recommendations for fat, saturated fat, fibre and sugar, without a radical change in eating habits, was by simply replacing half the 'junk' foods by an isocaloric amount of fresh fruit and vegetables. In addition there was a marked improvement in the intakes fo beta-carotene, vitamin C, B6 and folic acid. These improvements in diet are of particular importance to children as it is well known that the period most vulnerable to nutritional distortions is during growth and development. No matter which way we looked at the data is clear that not only are the school children's diets unsatisfactory from the view point of prevention of cardiovascular disease in later life but they also leave much to be desired from the view point of the wide range of nutrients known to be important for general health, growth and development. If this is true for the mean values obtained, it will be even more true for the 'high risk groups'.
