While much of the below fits with info from other sources; I would like to see the studies though. My GI specialist specifically told me to eat a bran fiber to prevent cancer. ANd he is at a teaching hospital........fortunately I recently changed over to vegetables for their nutrients and and fiber.

Bran is by far the worst kind of fiber to consume and increasing dietary intake of fibre has shown many harmful side-effects as Barry Groves writes in his article Climb Down from the Bran Wagon: “. . . bran has a far higher fibre content than vegetables and bran was a practically worthless by-product of the milling process which, until then, had been thrown away.
Now, virtually overnight, it became a highly priced profit maker. Bran is quite inedible – there is no known enzyme in the human body that can digest it. Tests into the supposed benefits of increasing dietary intake of fibre soon showed that there could be other harmful side-effects:
Because it is indigestible, bran ferments in the gut and can induce or increase flatulence (gas), distension (bloating), and abdominal pain.
Although it is supposed to travel through the gut at a faster rate, it does not always do so and it has been shown to cause blockages.
All the nutrients in food are absorbed through the gut wall and this takes time. It should be obvious, therefore, that if the food travels through faster, less will be absorbed. And, indeed, this is the case. Fibre is found to inhibit the absorption of zinc, iron, calcium, phosphorus, magnesium, energy, proteins, fats and vitamins A, D, E and K.
Phytate associated with cereal fibre (bran) [as well as grains, seeds, nuts and legumes] also binds with calcium, iron, and zinc, causing malabsorption.
For example, subjects absorbed more iron from white bread than from whole meal bread even though their intakes of iron were fifty percent higher with the whole meal bread. (25) Also, while white bread must have added calcium, the law does not require it of whole meal bread.
Bran fibre has also been shown to cause faecal losses, and negative balances of calcium, iron, zinc, phosphorus, nitrogen, fats, fatty acids and sterols [cholesterol, certain vitamins, adrenal hormones, etc.] thus depleting the body of these materials. (A negative balance is where more is lost from the body than is absorbed, i.e. the body’s stores are depleted.)
