The Effect of Buckwheat and Couscous on Satiety and Food Intake in Young Adults

The Effect of Buckwheat on Blood Glucose, Satiety and Food Intake

A diet rich in whole grains has been linked to multiple beneficial health outcomes, including cardiovascular health, weight loss and a decreased risk of acquiring type 2 diabetes. However, grain products vary due to their botanical origin, composition, and post-harvest processing. While wheat is considered a dominant grain crop in Canada, the minor crops, including gluten-free buckwheat, become popular alternatives to wheat products such as couscous. Both buckwheat groats and couscous are traditionally consumed in the form of the porridge or side dish, however, their acute effects on satiety and food intake remain unknown. The objective of this study is to investigate the short-term effects of couscous and buckwheat on satiety and short-term food intake in young adult males.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Food intake	The amount of energy (kcal) consumed ad libitum with the test meal (pizza lunch) two hours later.	120 minutes
Subjective appetite	The subjective assessment of appetite parameters including a desire to eat, fullness, hunger and a prospective food consumption measured with 100 mm Visual Analogue Scales with two opposite statements at each end (e.g., for the hunger scale, 0 mm means not hungry at all, and 100 mm means very hungry).	0-120 minutes

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Subjective feeling of physical comfort	The subjective assessment of wellness and gastrointestinal symptoms including a feeling of nausea, diarrhea, flatulence, and other parameters measured with 100 mm Visual Analogue Scales with two opposite statements at each end.	0-120 minutes
Subjective perception of food palatability (pleasantness)	The pleasantness of the meals measured with 100 mm Visual Analogue Scales with two opposite statements at each end (e.g., 0 mm means that food is not pleasant at all, and 100 mm means that the food is very pleasant).	0, 120 minutes
