Pulses, Satiation, Food Intake and Blood Glucose

Pulses have the potential to be positioned as a food for body weight and metabolic control based on their composition, effects on rate of digestion and absorption of fat and carbohydrates, and effects on satiety. However, the role of individual pulses incorporated into a mixed meal on regulation of food intake, satiety and glycaemic control remains unclear. Therefore, the objective of our study was to determine the effects of ad libitum consumption of pulse meals (treatments) on food intake at an ad libitum pulse meal, food intake at an ad libitum pizza meal at four hours, subjective appetite and blood glucose.

Treatment and study plan

dietary treatment

Other

A within-subject, balanced repeated-measures design was followed where subjects received 4 treatments or control over 5 weeks approximately 1 week apart. The pulse treatments contained: (1) chickpeas (Primo, Toronto, ON), (2) lentils (Primo, Toronto, ON), (3) navy beans (Ferma, Toronto, ON) or (4) yellow peas (Nupak, Toronto, ON).

Primary outcomes

  1. Short-term energy intake

    Time frame: over 280 min

    Energy intake was measured at the treatment meal (0-20 min) and at a pizza meal (second meal) provided four hours later (260-280 min).

Secondary outcomes

  1. Blood glucose and satiety

    Time frame: 20, 40, 60, 110, 140, 200, 260, 280, 300, 320 and 340 min

    Following treatment meal consumption, blood glucose and appetite were measured at 20, 40, 60, 110, 140, 200 and 260 min and are reported as pre-second meal values. Following the pizza meal, blood glucose and appetite were measured at 280, 300, 320 and 340 min and are reported as post-second meal values.
