About this study

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.

Split Red Lentil Muffin

Other

Consumption of split red lentil muffin; consumption of ad libitum pizza test meal after 180 minutes

Wheat Muffin

Other

Consumption of wheat muffin; consumption of ad libitum pizza test meal after 180 minutes

Small Green Lentil Chili

Other

Primary outcomes

  1. Satiety

    Time frame: Acute: 0, 15, 30, 45, 60, 90, 120, 150, and 180 minutes after treatment consumption

    Satiety will be measured using 100mm visual analog scales (VAS) rating appetite sensations of hunger, fullness, desire to eat, and prospective consumption

  2. Food Intake

    Time frame: Acute: 180 minutes following consumption of treatment

    Food intake will be measured as kilocalories using an ad libitum cheese pizza test meal

Secondary outcomes

  1. 24-hour Energy Intake

    Time frame: Acute: 24 hours

    24-hour energy intake will be measured by providing electronic food scales to participants to weigh and record all food and drink consumed for the rest of the day after leaving the study visit
