Background Plant sterols are plant derived dietary compounds that are structurally similar to cholesterol. Plant sterols reduce cholesterol absorption, and therefore plant sterol enriched functional foods are designed to lower blood cholesterol level. Reduction of cholesterol absorption increases the level of intraluminal cholesterol, and high intraluminal cholesterol concentration has been ass...

BACKGROUND Plant sterol supplementation was shown to reduce total and LDL-cholesterol concentrations, whereas endurance training was shown to increase HDL-cholesterol concentrations and decrease triacylglycerol concentrations. OBJECTIVE The objective was to examine the effect of plant sterols, endurance training, and the combination of plant sterols and endurance training on plasma lipid and ...

BACKGROUND Increased consumption of foods containing plant sterols has the potential to reduce the incidence of coronary heart disease (CHD) and thus reduce costs associated with treating that disease in a significant way. This paper reports the results of an investigation of the potential monetary benefits of allowing foods enriched with plant sterols to be marketed in Canada. OBJECTIVE The ...

Dietary plant sterols supplementation has been demonstrated in some studies to lower plasma total and LDL cholesterol in hypercholesterolemic subjects. The cholesterol lowering action of plant sterols remains to be investigated in subjects with the metabolic syndrome. In a randomized, crossover study of 2 x 4 week therapeutic periods with oral supplementation of plant sterols (2 g/day) or place...

Phytosterols (PS, comprising plant sterols and plant stanols) have been proven to lower LDL-cholesterol concentrations. The dose-response relationship for this effect has been evaluated in several meta-analyses by calculating averages for different dose ranges or by applying continuous dose-response functions. Both approaches have advantages and disadvantages. So far, the calculation of average...

Coronary patients with low baseline ratios of serum cholestanol and plant sterols to cholesterol (indicating low cholesterol absorption) but not those with high ratios (high absorption) experienced reduced recurrences of coronary events during simvastatin treatment in the Scandinavian Simvastatin Survival Study. Thus, in the present study, serum cholesterol, its precursor sterols (reflecting ch...

We read with interest the paper by Miettinen et al. (1) demonstrating that the higher the absorption of cholesterol, the higher the plant sterol contents are in serum resulting in their higher contents in atherosclerotic plaque. The prospective Cardiovascular Munster (PROCAM) study found that people in the upper quartile of sitosterol levels had a 1.8-fold increased risk of major coronary event...

rice bran sterols have antioxidant activity as well as physiological and biological effects. because of these benefits, the aim of this study is evaluating the quantity and quality of iranian rice bran sterols. three widespread iranian rice cultivars (khazar, hashemi, and alikazemi) were used for determination of their sterol contents. two methods of sample preparation were compared and the bet...

The effects of stigmasterol, sitosterol, campesterol, and cholesterol on the phase properties of dipalmitoylphosphatidylcholine bilayers have been compared by differential scanning calorimetry and x-ray diffraction. The sterols were equally effective at progressively reducing the cooperativity and the enthalpy of the dipalmitoylphosphatidylcholine phase transition as their concentrations in the...
