Anthony J. DiMarino, Jr., MD: Hydration, activity, walking, exercising is important and fiber. And hydration, we recommend eight, eight ounce glasses of water a day for most individuals, except for those folks who have a problem with the amount of—that amount of fluid. For example someone who has heart..heart disease and has been in heart failure or has a kidney problem. You might need to check with your physician first, but someone who's otherwise healthy that's the recommended amount of fluid. Fluid is fluid with the exception of alcohol. Alcohol is not something we consider a hydrating substance because in fact, alcohol's a diuretic or mild diuretic and you start to lose fluids if you drink alcohol. But other than alcohol, just or water or any type of, even an orange for example has a lot of fluid in it. So if you eat an orange and chew it well, you're going to get a lot fluid as well as the fiber.
