Dr. Hibberd's answer:
 

Yes. Oat bran cereal contains soluble fiber which helps reduce the absorption of dietary fat and cholesterol at the gut level.
 

About 10-20 percent of our blood cholesterol levels are tied to what we eat, with the rest reflecting our liver synthesis of cholesterol. So the reduction of saturated fat and cholesterol in the diet is often enough to bring many adults and children's cholesterol levels into recommended healthy ranges.
 

About two out of three adults have high cholesterol or high triglycerides. Oat bran has soluble fiber that not only supplies dietary bulk to reduce cancer risk and improve bowel function, but also mops up and reduces the absorption and reabsorption of excessive fatty acids and cholesterol. It's also filling, inexpensive, and easy to use for all ages. 
 

An adult should aim to eat 40 grams of fiber per day — including 30 grams of soluble fiber.
