Cholesterol Metabolism in Heterozygous Phytosterolemia
Summary
The purpose of the study is to examine the effect of plant sterols on cholesterol absorption and synthesis in people with heterozygous phytosterolemia.
Description
A plant sterol supplementation study will be conducted in individuals who are heterozygous for phytosterolemia compared to non-carriers. The study will use a double-blind, randomised, crossover, placebo-controlled design in which participants will consume 2 treatments including 2.6 g of plant sterol pills and a placebo pill, each for 4 weeks. A 4 week washout period will separate the two treatment periods. Plant sterol concentrations will be measured by gas liquid chromatography and absorption will be measured by the ratio of campesterol to lathosterol in plasma. Cholesterol absorption and synthesis will be measured by dual stable isotope technique, involving simultaneous administration of 13C-cholesterol and deuterium oxide, respectively.

Phytosterol Supplementation and Cardiovascular Risk
This study examined the effects of 2.6 g/d of phytosterol ingestion on LDL cholesterol metabolism. It is expected that this dose will significantly reduce LDL cholesterol after 12 weeks o...
Hypercholesterolemia is a well-established risk factor for the development of atherosclerosis, a component of cardiovascular disease (CVD). The National Cholesterol Education Program advis...
Since it is very difficult to have the real thing (Mediterranean diet) we need to find an alternative to reduce cardiovascular disease (CVD) risk in subjects with moderate hypercholesterol...
Comparison of Low and High Phytosterol Diets With Respect to Cholesterol Metabolism
The objective of this study is to compare cholesterol absorption and metabolism after feeding diets naturally low or high in phytosterols. All meals will be prepared in a metabolic kitche...
Addition of Phytosterols to a Low Phytosterol Diet
Studies have shown that phytosterols will lower LDL cholesterol. Typical diets can contain between 250 to 500 mg of naturally-occurring phytosterols. Long-term studies with phytosterol-con...
