    We have earlier demonstrated that muesli enriched with oat beta-glucan effectively lowered serum LDL cholesterol. Addition of plant stanols further lowered LDL cholesterol. Besides these hypocholesterolemic effects, beta-glucan and plant stanol esters (PSE) may also affect inflammatory processes. Forty-two mildly hypercholesterolemic subjects randomly consumed for 4 wk (crossover design) control muesli (4.8 g control fiber), beta-glucan muesli (4.8 g oat beta-glucan), or combination muesli (4.8 g oat beta-glucan plus 1.4 g stanol as PSE). Changes in cytokine production (IL-6, IL-8, and TNF-alpha) of LPS-stimulated peripheral blood mononuclear cells (PBMC) and whole blood were evaluated, as well as changes in plasma high-sensitivity (hs)-CRP. Additionally, changes in expression profiles of 84 genes involved in atherosclerosis metabolism were assessed in isolated PBMC. IL-6, IL-8, and TNF-alpha production by PBMC and whole blood after LPS stimulation did not differ between the treatments. Also high-sensitivity C-reactive protein (hs-CRP) levels were similar. beta-Glucan consumption did not change gene expression, while only 3 genes (ADFP, CDH5, CSF2) out of the 84 genes from the atherosclerotic risk panel were differentially expressed (p < 0.05) after consumption of PSE. Consumption of beta-glucan with or without PSE did not influence inflammatory parameters in mildly hypercholesterolemic subjects.
