June 18/Albany, Ga./PRNewswire -- A new study, released in the current British Journal of Nutrition, showed that consuming peanut butter or peanuts for breakfast can control blood sugar throughout most of the day, even after eating a high carbohydrate lunch. In addition to this "Second Meal Effect," peanuts and peanut butter caused a significant reduction in the desire to eat for up to 12 hours and a significant increase in the secretion of the hormone PYY that promotes satiety and feelings of fullness.
The study, "Acute and second-meal effects of peanuts on glycaemic response and appetite in obese women with type 2 diabetes risk: a randomized cross-over clinical trial," was conducted jointly by Purdue University and the Federal University of Vicosa in Brazil. The principal investigator, Dr. Richard Mattes of Purdue University, explained, "If you include peanut butter or peanuts at breakfast, you not only diminish the rise in blood sugar at breakfast but also again after lunch, helping to reduce blood sugar over a very large portion of the day."
