“Commercial interests were quick to see the potential in the recommendation and jump on the bran wagon. Burkitt’s recommendation was based on vegetable fibre, but bran (cereal fibre) has a far higher fibre content and bran was a practically worthless by-product of the milling process that, until then, had been thrown away. Almost overnight, it became a highly priced profit maker. Although totally inedible, backed by Burkitt’s fibre hypothesis, bran could now be promoted as a valuable food. But Dr. Hugh Trowell, Burkitt’s partner and another strong advocate of dietary fibre, stated in 1974 that:”A serious confusion of thought is produced by referring to the dietary fibre hypothesis as the bran hypothesis, for many Africans do not consume cereal or bran”"

While we should get healthy fiber from fruits and vegetables, we should avoid “bran” fiber like the plague. Bran fiber causes lots of issues related to the gut health which we have already shown is the real marker for health (and risks of cancer). The grain is not our friend…but just a cheap source of “fiber” that is marketed by any company selling processed foods…they are not selling health, just their product as “healthy”. Huge difference.
