Peanut butter can control blood sugar and appetite, study finds
New research published in the British Journal of Nutrition found that eating peanuts or peanut butter at breakfast can help keep your blood sugar stable throughout the day.
Not only that, but peanut butter can also help to reduce appetite – even following a high-carbohydrate lunch.
Researchers at Purdue University and the Federal University of Vicosa in Brazil studied the effects of peanuts on appetite and glycemic response in obese women with type 2 diabetes risk.
Over three phases of the study, the women ate either 1.5 ounces of peanuts or 3 tablespoons of peanut butter with breakfast. Another group ate no peanuts or peanut butter with breakfast.
All three groups then ate the same high-carbohydrate lunch of white bread and strawberry jam. Blood samples were taken from the women following breakfast and lunch.
Researchers found that peanut butter or peanuts help promote the secretion of the appetite-supressing hormone peptide YY (PYY). The women who had eaten peanut butter or peanuts reported feeling fuller longer, and they also had lower blood sugar after lunch.
It appeared that peanut butter had a slightly more beneficial effect on the glycemic response than peanuts. Researchers said that the combination of high protein, fiber and healthy oils is what makes peanut butter a good option for blood sugar and appetite control.
"Combined with findings from other work, this new research provides additional reasons to start your day with peanut butter and include a snack of peanuts in the late afternoon if you want to control your appetite and blood sugar too," said Pat Kearney, MEd, RD, program director for The Peanut Institute.
