Research Subject Recruitment

Would you like to be a subject in a nutrition research trial? The following studies are recruiting for subjects:

Study on the impact of drinking common beverages with breakfast on blood glucose and insulin levels

Participants are being sought to participate in a study that will look at how drinking different common beverages (milk, low-fat milk, nonfat milk, orange juice, coffee and water) with a meal changes blood sugar and insulin levels after eating.

Participants will come to Purdue Clinical Research Center on six mornings separated by at least one week. On each of the mornings, participants will consume a breakfast with one cup of a beverage. Blood samples will be taken before and every 30 minutes after eating for four hours to test blood sugar and insulin levels. Each test day will last about five hours.

Measurements include calories and nutrients in the participant's diet, weight/height/lean tissue, and blood glucose and insulin levels. Participants will receive $500 for completing the study.

Men and women ages 35 to 65 who are overweight, nonsmoking, not pregnant and interested in participating in this study should contact Jia Li at or 49-41706 for more information.

The principal investigator is Wayne Campbell, professor in the Department of Nutrition Science.

Almonds and weight management study

Participants are needed by the Department of Nutrition Science to study the role of almonds in weight management. 

The principal investigator for the study is Richard Mattes, Distinguished Professor of Nutrition Science.

Men and women age 18-60, overweight but generally in good health, who have no nut allergies and who are interested in participating in this study should contact Jaapna at  Participants may earn up to $200 upon completion of the study.
