Resheachers have discovered that pairing "Peanut Butter" with "Whole Wheat" bread enables the body to get a better balance of amino acids. Diane Birt, PhD, a professor of food science at Iowa State University said “Wheat lacks some amino acids and peanuts have the amino acids lacking in wheat." Together they make a whole complete balanced amino acid source. “When your body is synthesizing proteins, it needs all the amino acids”. 
 

Apples contain the flavonoid quercetin, and grapes contain catechin. Studies show that pairing the two compounds may improve cardiovascular health by making blood platelets less sticky so they don’t clump together and clog arteries. “The combination tends to have a mild anticoagulant effect,” says Barry Halliwell, PhD, nutrition professor at the National University of Singapore, who co-authored a study on quercetin and catechin. Leave the peel on the Apples, as a bulk of the antioxidants are in the peel.
