Dietary control of hyperlipoproteinemia.

A prospective study of the effect of dietary control of hyperlipoproteinemia (HLP) was carried out in 1,800 adult out-patients. The patients with type II A were treated with a diet low in saturated fat and cholesterol, with substitution of polyunsaturated fat. Additional carbohydrate and alcohol restriction was applied to patients with types II B, III and IV HLP. Caloric restriction was prescribed for overweighted patients. These diets were followed by sequences of stabilizing diets which were modified quarterly. After 7 years the best results were obtained for type IV (50%) followed by II B (22%). The nutritional HLP treatment, in keeping with the metabolic dependence, corrected HLP to one third of the initial sample, without improving the objective cardiovascular disturbances.
