Acute Effect of Animal and Vegetable Protein Rich Meals With Comparable Dietary Fibers Content on Appetite Sensation and Energy Intake (PAVA-II)

29 giugno 2016 aggiornato da: 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:

  1. Subjective appetite (VAS) (every 30 min for 3 hours)
  2. Ad libitum EI (3 hours after lunch test meal)

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Vegetable protein meal
Vegetable protein meal based on legumes (3.6 MJ, 19E% protein, 28 g dietary fibers)
4-arm crossover study with the objective to examine if vegetable protein (beans and peas) can suppress subjective appetite (VAS and ad libitum EI) compared to isocaloric meals enriched with either red meat or egg with similar distribution of macronutrients and content of dietary fibers.
Sperimentale: Egg protein meal + fibers
Protein meal based on eggs and added pea dietary fibers (3.6 MJ, 19E% protein, 28 g dietary fibers)
4-arm crossover study with the objective to examine if vegetable protein (beans and peas) can suppress subjective appetite (VAS and ad libitum EI) compared to isocaloric meals enriched with either red meat or egg with similar distribution of macronutrients and content of dietary fibers.
Sperimentale: Egg protein meal
Protein meal based on egg without added dietary fibers (3.6 MJ, 19E% protein, 6 g dietary fibers)

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Ad libitum energy intake
Lasso di tempo: Measured on 4 separate test days in a crossover design. Each test day is separated by >1 week. Assessed 180 min after each of the 4 test meals.
180 min after each test meal an ad libitum meal of spaghetti bolognese is served, and the total energy intake is recorded.

Misura Descrizione
Lasso di tempo
Acute 3-h changes from baseline in subjective appetite sensations using visual analogue scales
Lasso di tempo: Measured on 4 separate test days in a crossover design. Each test day is separated by >1 week. On each test day appetite sensations are measured prior to the test meal (time 0) and 15, 30, 60, 90, 120, 150, 180 minutes post intake
