Your cholesterol is the fourth number Dr. Oz wants you to know. At your next physical, have your doctor check your cholesterol ratio. "You want your healthy HDL cholesterol to be greater than 50," he says. "You want that LDL, lousy cholesterol, under 100."
The right cholesterol is similar to plaster—it can help your body heal itself. "The body will try to repair the injuries that are caused, for example, by high blood pressure," he says. "But if your cholesterol is not of the right kind, it can be a problem."
