During 1980 and 1982, 164 men aged 45-54 in North Edinburgh and West Fife participated in a 7-day individual weighed dietary survey. The mean energy intake was 11.2 MJ (2700 kcal), 38.1 per cent of which came from fat and 6.7 per cent from alcohol. The P:S ratio was 0.30 and the mean daily fibre intake 19.8 g. Saturated fatty acids accounted for 16.3 per cent of the energy and polyunsaturated fatty acid for 4.6 per cent. Oleic acid was the principal dietary fatty acid accounting for 32.4 per cent of fatty acids. The major polyunsaturated fatty acid was linoleic acid and contributed 3.5 per cent of energy. Cereal and cereal products were the principal source (30.8 per cent) of linoleic acid. Though this study was conducted prior to the publication of recent dietary recommendations, a small proportion of the men were achieving some of them but few would have met the recommendations in full.
