Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Lentil Satiety study will examine the effects of replacing wheat and rice with two types of lentils within food products (muffins and chilies) on satiety and food intake in healthy adults.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Lentil Satiety study will examine the effects of replacing wheat and rice with two types of lentils (small green Eston and red split) within food products (muffins and chilies) on satiety and food intake in healthy adults, for a total of 6 study treatments. A total of 3 to 6 study visits (corresponding to consuming all muffins and/or all chilies) will take place where participants will consume one of the study treatments and subsequently complete satiety questionnaires over 180 minutes to measure satiety as subjective appetite sensations (hunger, fullness, desire to eat, and prospective food consumption). At 180 minutes, participants will receive ad libitum pizza and bottled water to consume until they are comfortably full for a measure of weighed food intake. At the end of each study visit, participants will be given a food scale and instructed to weigh and record all food and drink consumed for the remainder of the day for a measure of 24-hour energy intake.
