Individuals with high cholesterol levels above 8 mmol L have been shown to benefit from dietary and other therapeutic interventions resulting in a lower incidence of coronary heart disease than those untreated. Individuals with moderately raised cholesterol have not been shown to improve their prognosis by attempts at reduction. Nevertheless there is considerable public pressure to determine cholesterol levels. There is no doubt that a number of organisations continue to offer cholesterol screening as a sort of loss leader to enhance other more worthwhile health promotion initiatives. Improved diet There are still many aspects of the average diet which are less than satisfactory. The Committee on Medical Aspects of Food Policy COMA report showed that as a nation we consume food containing too much salt unrefined sugar and fat and too little fibre. The average percentage of food energy derived by the population from saturated fatty acids is 17 per cent and from total fat 40 per cent. Eight per cent of men are obese and 12 per cent of women. Of course the individual must have a choice and staff restaurant menus cannot reasonably exclude for example chips. However healthy choices should always be available and labelled. Many organisations use the traffic light system for labelling menu items with red indicating the high fat content food and green the other extreme. The BBC in Northern Ireland showed a decrease in the consumption of white bread butter non-fibre cereals cream and dressed salads over a period of about two years when healthy alternatives were introduced in its staff restaurants. Gradual change to a healthier lifestyle can have a major effect on long-term national health. Smoking There is no doubt that smoking damages your health. National initiatives are limited to activities such as National No-Smoking Day. Audio-visual material is available .
