Participant Flow

Participants were recruited at the Richardson Centre for Functionals Foods and Nutraceuticals, University of Manitoba, Winnipeg during July 2010 to May 2011

Over 200 subjects were screened; 45 subjects were enrolled in the study and randomly assigned to the experimental diets (treatment groups).

PRIMARY outcome

Timeframe: Beginning and end of each phase

Serum LDL cholesterol will be estimated using the Friedewald equation.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: End of each phase

The rate of cholesterol absorption and synthesis will be measured in each intervention phase using single stable isotope labelling technique.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 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.

SECONDARY outcome

Timeframe: 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.
