Do you need to get more fiber in your diet? Most likely, Dr. Oz says. The average American gets just seven grams of fiber a day. But women need about 25 grams a day, and men need 35 grams a day. "That's somewhere between seven and nine helpings of fruits and vegetables," he says.
If you radically increase your intake of fiber, though, you may feel gassy. "Your intestinal tract isn't ready for it," Dr. Oz says. "The fiber in the bowel is permeated by all these bacteria, the bacteria eat the fiber, and they make gas. That's their waste product. So you've got to slowly build up when you add fiber to your diet. But at the end of the day, you're going to have some gas. But it's a good sign because you're digesting food that's good for you."
