Peanut is a kind of "satiety" food, which can make you feel full or full for a longer time. An article published in the journal Nutrition and Metabolism found that people who snack on peanuts eat less. Dr. Martes, a professor of nutrition science at Purdue University in the United States, said: "The high satiety of peanuts is not only the result of fat, dietary fiber and protein content, but also the result of the synergy of all factors." Kathy mcmanus, head of the nutrition department at Brigham and Women's Hospital, said that if you eat peanuts or peanut butter for breakfast, you can reduce the amount of food you eat this day.
