Is your stomach growling only a few hours after breakfast?You may want to add peanuts or peanut butter to your morning meal, a new study suggests.

Researchers from Purdue University and the Federal University of Vicosa in Brazil found that consuming peanut butter or peanuts for breakfast can help control hunger and regulate blood sugar all day.

Study participants either ate peanuts or peanut butter, or did not eat any at all. They also ate orange juice and cream of white for breakfast. Later, they consumed a lunch of white bread and strawberry jam. Blood samples and appetite rankings were taken over time to assess blood sugar levels and satiety.

Those who ate peanuts or peanut butter reported feeling fuller up to 8 to 12 hours later and had lower blood sugar, even after eating a lunch high in carbohydrates.

The researchers said that peanuts' high levels of protein, fiber and oils help maintain blood sugar and contribute to feelings of fullness.

The study was published recently in the British Journal of Nutrition.
