Description This study consists of four dietary phases which are separated by at least 21 days wash-out period. While participating in a treatment phase, the Richardson Centre will provide subjects with all meals for the 35 day period. Breakfast meals will be consumed under the supervision of the research staff and lunch, dinner and snacks will be provided to take home in take-out packaging. While subjects are on the wash-out period they will return to their normal diet. The meals are on a 7 day rotating schedule that reflect an average Canadian diet.
