Dietary patterns and nutritional status in free-living older white men with established vascular disease

Thirty-nine white men aged 51-84 years with established vascular disease were studied to investigate the effect of fish oil capsules on the regression of these lesions. This article deals with the baseline data of the study. The subjects completed a 7-day dietary record, weight and height were measured and a fasting blood sample was analysed for proteins, haematological values and certain vitamins. Dietary analysis indicated that the mean energy intake was 8,552 kJ (SD = 2,095). The energy distribution was 15.5% protein, 33.6% fat and 46.4% carbohydrate. In the light of the recommended dietary allowances the diet was lacking in zinc, vitamin B6 and folic acid, which suggests that the subjects might be deficient in these micronutrients. Although the diets were lacking in these nutrients, no clinical stigmata were observed. The subjects averaged a body mass index of 26.1 and could therefore be classified as overweight. The mean haematological values as well as the plasma vitamins were within the normal range. In conclusion it can be said that the men consumed a diet that was too high in fat and that the diet lacked certain micronutrients.
