There is so much confusion out there in the food world already and it is being further contaminated by nebulous terms that deceive consumers. And by the way, don’t rely on nutritionists, pediatricians and other so-called experts. Prepared cereal companies are paying them off as “independent experts” to rebut negative talk about breakfast cereals and praise certain sugary cereal brands as their preferred breakfast food. (A news report reveals Kellogg’s pays its Breakfast Council team $13,000 a year to say positive things about their products online.) [Daily Mail Nov 21, 2016]
A revealing study just published in the journal CELL indicates the lack of fiber in the diet allows microbes (germs) to eat the mucus lining of the gut that can result in complete erosion of the gut and may allow invading bacteria to infect the colon. [Medical Daily Nov 18, 2016]
But all sources of fiber are not the same. Fiber from apples and bananas come with loads of sugar and provide no bran like cereal grains do.
A pointed report published in Scientific American notes that whole grains may in fact lack the very fiber that is touted to confer health benefits. Whole grains are often processed grains and they may or may not provide bran, the key essence of whole grains. [Scientific American July 25, 2013]
It is phytic acid from bran that prevents colon cancer. [Anticancer Research Sept-Oct 1999; Carcinogenesis Aug 2000] Bran itself is not nearly as healthy as phytic acid in the prevention of colon cancer. [Nutrition Cancer 1997] In 1985 researchers identified phytic acid (aka inositol hexaphosphate or IP6), present in many but not all fiber-rich diets, that inhibits cancer via its ability to bind to iron.
