Statistics show nearly 2 in 5 U.S. adults have high cholesterol, the excess of fat in the blood that can raise the risk of heart disease. For decades, people were told that foods high in cholesterol — eggs and butter, for example — were the major culprits. Now dietary cholesterol is thought to play only a minor role.
