U of A/ U of M Beans and Peas Health Claim Project
The purpose of this study is to compare how regularly eating (dried) beans or peas or rice (control) lowers blood lipids, particularly Low Density Lipoprotein cholesterol and total cholesterol, in mildly hypercholesterolemic men and women. The investigators hypothesize that regularly eating beans or peas will significantly improve blood lipid profiles in these people.
Participants in this study will consume 1 study food item 5 out of 7 days a week containing beans or peas or rice for a total of 6 weeks. This study will benefit Canadian pulse growers by enhancing development of food products for human consumption and supporting marketing strategies to increase awareness that a diet rich in pulses can improve human health. Measuring changes in blood and urinary polyphenol levels will help to verify whether these compounds play a role in the beneficial actions of beans and peas and subsequently assist with the identification of the beneficial bean/pea components. This in turn, will enable crop breeders to select for plants that are rich in these compounds.

Experimental: Bean consumption to lower cholesterol
This arm will consume 90 grams of beans per day for 5 out of 7 days for 6 weeks.
Dietary Supplement: Beans
90g of beans per day for 5 out of 7 days per week will be given to participants for 6 weeks to determine the cholesterol lowering effects of various pulses.
Placebo Comparator: Control (rice) consumed to show results
The control group will consume 90 grams of rice per day for 5 out of 7 days for 6 weeks.
Dietary Supplement: Control (rice)
90g of rice per day will be given to the control group to demonstrate the cholesterol lowering effects of the experimental group.
Experimental: Peas consumed to lower cholesterol
This arm will consume 90g of peas per day for 5 days out of each week for 6 weeks.
Dietary Supplement: Peas
90 grams of peas will be consumed 5 out of 7 days per week
