So the bacteria use an enzyme called glucosyltransferase to cut the bond between them, use the fructose for energy, and add the glucose to a growing chain of glucose molecules called a glucan.
Glucans allow the bacteria to attach firmly to the surface of the tooth, and form dental plaque, which is a sticky collection of bacteria, proteins from saliva, and dead cells from the lining of the mouth.
And unlike wheat and most other grains, oats contain large amounts of a specific type of fiber called beta glucan, which studies have consistently linked to healthier cholesterol scores and a reduced risk for diabetes and cardiovascular disease.
