This human clinical trial is using a randomized crossover design to examine the effect of two varieties of beans compared to beef on satiety and food intake in older adults.
This human clinical trial is using a randomized crossover design that includes 3 study visits separated by washout periods of at least 1 week. Each study visit will last approximately 4 hours and will occur at the Human Nutraceutical Research Unit (HNRU) at the University of Guelph. Study visits will occur in the morning and begin with measurement of fasting body weight. Participants will then complete a baseline satiety questionnaire before they consume a breakfast test meal (that includes either red kidney beans, black beans or extra-lean ground beef). After the breakfast meal, participants will complete a palatability questionnaire. They will also complete more satiety questionnaires at 15, 30, 45, 60, 120, 150 and 180 minutes. After 180 minutes, participants will be consume an ad libitum pizza lunch meal until they are comfortably full. Participants will then be sent home with a food scale and instructions to record everything they eat and drink for the remainder of the day.
