Acute Effect of Animal and Vegetable Protein Rich Meals With Comparable Dietary Fibers Content on Appetite Sensation and Energy Intake (PAVA-II)
2016年6月29日 更新者：Arne Astrup、University of Copenhagen
Background:
- New Nordic diet guidelines advocate a reduction in consumption of protein from animal sources such as beef and pork, due to environmental concerns.
- Instead, intake of protein from vegetable sources such as legumes and pulses should be increased.
- A previous study showed that a meal enriched with vegetable protein increased the subjective sensation of satiety and decreased hunger and ad libitum energy intake (EI) compared to animal protein.
- This study did, however, not document that vegetable protein per se is more satiating than animal protein as the vegetable meal had higher fiber content. Fiber is a likely confounder.
- The protein from egg is sparingly investigated in relation to appetite. Few studies have found that eggs have a high satiety index but further investigation is needed.
Objective:
- To examine if vegetable protein (beans and peas) can suppress subjective appetite (VAS and ad libitum energy intake) compared to isocaloric meals enriched with either red meat or egg with similar distribution of macronutrients and content of dietary fibers.
Design:
Single-blind randomized 4-way crossover meal study
Subjects:
33 young healthy men (Age: 18-50 years; BMI: 19-30 kg/m2). Expected completers: n=30.
End points:
- Subjective appetite (VAS) (every 30 min for 3 hours)
- Ad libitum EI (3 hours after lunch test meal)
