The researchers also found that after the participants ate high-protein leguminous patties for breakfast, Raben told Life Science: "Compared with eating high-protein or low-protein leguminous patties for breakfast, their lunch calories decreased by 65,438+02% to 65,438+03%-a difference of 95 to 65,438+005 calories." , pork and potatoes (high protein patties); Broad beans and split beans (high protein bean patties); Or broad beans, green beans and potatoes (low-protein bean cakes). All meat pies contain various spices, such as rapeseed oil and butter, high-protein meat pies and high-protein bean meat pies.
19% of calories come from protein, and 53% comes from carbohydrates. However, the difference between high-protein patties lies in the fiber content of each kind of patties: high-protein patties have only 6 grams of fiber per100g, while high-protein bean patties have 25 grams of fiber per100g. On the other hand, low-protein bean pies.
Only 9% calories come from protein, while 62% calories come from carbohydrates. 10g of meat pie contains10g of fiber [What kind of food is the most full? ]
According to the research results, the higher the fiber content in high-protein legume patties, the higher the satiety or satiety level of participants. The research results were published in the journal of Food and Nutrition Research in June 65438+ 10/9. Raben told Life Science magazine:
"Fiber and protein work through different mechanisms." The body does not break down fibers, so it will stay in the gastrointestinal tract until it is excreted. However, protein is digested and absorbed by the human body, so that its components can be used by human tissues, including the brain.
The researchers pointed out that this result does not necessarily mean that eating plant protein always makes people feel full than eating animal protein. "It is useful to test foods with similar fiber and protein content," Raben said.
One limitation of this study is the different tastes of food: participants said that high-protein watercress cake is obviously not as delicious as high-protein meat pie and low-protein watercress cake. This is important, the researchers say, because generally speaking, more delicious food is considered less likely to be full than unpalatable food, which may affect the research results.
The researchers said that this study is the first time to directly compare the effects of a vegetable diet based on beans and vegetables on appetite regulation. Similar studies compare the protein of soybean and dairy products (in the form of whey, casein and milk), or use food substitutes (such as protein powder dissolved in water) instead of real food as experimental meals.
Researchers are interested in the environmental impact of these findings. Raben said, "From a global perspective, it will be more ecological to choose a vegetable-based diet."
