- Changs in Total Cholesterol [ Time Frame: Beginning and end of each phase ]Fasted total cholesterol concentration will be measured using the automated enzymatic methods.
- Changes in LDL Cholesterol [ Time Frame: Beginning and end of each phase ]Serum LDL cholesterol will be estimated using the Friedewald equation.
- Cholesterol Absorption/Synthesis [ Time Frame: End of each phase ]The rate of cholesterol absorption and synthesis will be measured in each intervention phase using single stable isotope labelling technique.
- Potential Gene-nutrient Interactions: CYP7A1 and APOE [ Time Frame: Once for each participant ]The Single Nucleotide Polymorphism (SNP) rs3808607 of CYP7A1 gene, rs429358 and rs7412 of APOE gene, and their associations with different blood lipid responses to beta-glucan interventions will be determined.
- Changes in Body Weight and Waist Circumference(WC) [ Time Frame: Every day for body weight; beginning and end of each phase for WC ]Body weight will be monitored every day when subject visits the Richardson Centre. Waist circumference will be measured at the beginning and end of each study phase.
