[Effect of diet on major risk factors in an organized population]

In the organized population, 364 male subjects aged 20-59 years (those with dyslipoproteinemias and borderline hypertension and patients with coronary heart disease) were on diet for 6 months, which resulted in a significant drop in plasma cholesterol, triglycerides, systolic and diastolic blood pressures, and body weight by 7.7%, 17%, 3%, 3.7%, and 5.3%, respectively. The portion of fat in the diet was reduced from 40% to 36% of total caloric value and that of sugar was decreased from 13% to 10%, at the same time complex carbohydrates and protein were increased from 8% to 12% and from 15% to 17%, respectively. A multiple stepwise regression analysis was used to define whether different variables were significant in lowering the risk factors.
