Acute dietary effects on diurnal plasma lipids in normal subjects.

The effects of different dietary carbohydrates and different dietary fats as well as of differently spaced dietary constituents on 24-h plasma free fatty acids and triglycerides were determined in healthy young males. If, in an isocaloric diet containing 15-20% protein, 37% fat and 43--48% carbohydrates, sucrose is compared with glucose, 24-h plasma triglycerides are significantly higher with the former carbohydrate. When palm oil (mainly 16 : 0 fatty acids) is compared with olive oil (mainly 18 : 1 fatty acids), 24-h triglycerides are significantly higher with the latter. If the carbohydrate component of a mixed meal is removed, alimentary lipemia is considerably greater. Our findings supplement long term studies regarding the effect of different dietary fats and carbohydrates on plasma lipids and allow calculation of "upper normal limits" for 24-h plasma triglycerides and free fatty acid patterns on isocaloric diets of "prudent" composition.

[Dietary management of familial Hypercholesterolemia in Children and adolescents -- a feasibility study (author's transl)].

The efficacy of a fat-modified, low-cholesterol diet was studied in 38 children and adolescents with familial hypercholesterolemia on an out-patient basis, and the results compared with those achieved with dietary treatment in hospital. On an out-patient basis, a 10% reduction of plasma cholesterol levels was achieved and maintained. However, no patient showed normalization of plasma cholesterol levels. During hospitalisation, the mean plasma cholesterol levels fell by 24%, beta-cholesterol levels by 27%. This resulted in normal plasma lipids in almost half of the patients. Our results demonstrate the efficacy of intensive dietary management in children and adolescents with familial hypercholesterolemia. Long-term results on an out-patient basis could probably be improved by early nutrition education and an improved supply of suitable dietary foods.

[Sitosterol in familial hyperlipoproteinemia type II. A randomized double-blind cross-over study].

The effect of beta-sitosterol on the lipid and lipoprotein level was evaluated in a randomised double-blind cross-over trial in 24 patients with primary familial type II hyperlipoproteinaemia over a period of 16 weeks. All patients completed the trial, however 10 of them had to be excluded from the evaluation due to fluctuations of their body weight or unreliable drug intake. Sitosterol lowered the total cholesterol level by 12.5% (P less than 0.01) from 9.96 mmol/l (3.69 g/l) to 8.37 mmol/l (3.23 g/l). The LDL-cholesterol level was lowered by 19.5% (P less than 0.05). The sitosterol concentration in plasma was consistently lower than 0.3% of total cholesterol. No side effects or tachyphylaxis was observed in the course of the trial. A return to normal of an increased serum cholesterol level by a combination of a lipid lowering diet and sitosterol monotherapy was only achieved in one patient.
