In a study that compared the satiability of beans and peas to veal and pork, it was found that the plant-based meal is more filling.
“Recent nutrition recommendations advocate a reduction in protein from animal sources (pork, beef) because of environmental concerns”, begins the study’s abstract. “Instead, protein from vegetable sources (beans, peas) should be increased. However, little is known about the effect of these vegetable protein sources on appetite regulation.”
With this in mind, the study’s objective was to “examine whether meals based on vegetable protein sources (beans/peas) are comparable to meals based on animal protein sources (veal/pork) regarding meal-induced appetite sensations.”
In total, 43 “healthy, normal-weight, young men completed this randomized, double-blind, placebo-controlled, three-way, cross-over meal test.” The meals were either high protein based on veal and pork meat (HP-Meat); high protein based on beans and peas (HP-Legume), or low-protein based on legumes (LP-Legume).
Researchers found that HP-Legume led to “higher fullness” than HP-Meat or LP-Legume. Furthermore, “satiety was higher after HP-Legume than HP-Meat”.
The study concludes; “Vegetable-based meals (beans/peas) influenced appetite sensations favorably compared to animal-based meals (pork/veal) with similar energy and protein content, but lower fiber content. Interestingly, a vegetable-based meal with low protein content was as satiating and palatable as an animal-based meal with high protein content.”
