Dietary data, mostly in the form of the frequency of consumption of foods, from the 9003 respondents in the Health and Lifestyle Survey were used to compare lifetime non-smokers with light, heavy and ex-smokers, taking account of age and social class. Non-smokers, of both sexes, were significantly more likely than smokers to consume, frequently, fresh fruit in summer and winter, fruit juice, cooked and canned fruit, salads in summer and winter, breakfast cereals, cakes, biscuits, puddings, pasta, poultry, light desserts and preserves. They were also more likely to choose 'brown' bread, semi- or skimmed milk, low fat or polyunsaturated spread and to eat breakfast. Smokers were likely to consume chips and processed meats frequently, to drink more alcohol, more cups of tea and coffee and take sugar in these beverages. The differences from the non-smokers were more marked in the heavy smokers. Ex-smokers only differed from non-smokers in consuming more alcohol, tea and coffee, and nuts, in consuming cakes and soft drinks less frequently and in being more likely to choose skimmed or semi-skimmed milk. The results extend previous findings, and suggest that the eating patterns of non-smokers are more in line with current dietary recommendations than those of light smokers or, more particularly, heavy smokers.
