Dear readers: Whenever I spot a link between food industry professionals and scientists, I get a queazy feeling in my stomach as their intention is almost by definition driven by profits and never by our health and well being.
In the 1999’s definition of “whole grain” by the American Association of Cereal Chemists (AACC) International, which is exactly that ominous kind of mixture of food industry professionals and scientists, “whole grain” can be any mixture of components of an intact grain (the bran, endosperm and germ) but the grains are allowed to be (and usually are), processed so that the parts are separated and ground before being put into foods.
To clear things up a bit – the “whole grain” is an INTACT grain – a fiber-rich coating of bran surrounding a starchy endosperm and a reproductive kernel called the germ. The fiber content is what’s synonymous with good health, good digestion, lower cholesterol, heart health etc.
When you separate these components and process them, the contents of healthy fiber and nutrients drop significantly.
The U.S. Food and Drug Administration adopted (to no wonder) the AACC definition in 2006, allowing the food industry to push out their products marketed as “whole grain” that contain very little fiber and lots of sugar.
As reported by the Scientific American’s text Whole Grain Foods Not Always Healthful from July 2013:
“An individual would have to eat 10 bowls of Multi-grain Cheerios, 16 slices of whole-wheat bread, or nine cups of brown rice to get the fiber recommended for an American adult for one day. “There’s nothing wrong with eating brown rice, but you can’t expect health benefits if you’re going to be eating brown rice as your source of whole grains,” David Klurfeld the national program leader for human nutrition in the Agricultural Research Service at the U.S. Department of Agriculture.”
When the whole grains are being processed (usually by grinding or flaking) to make them tastier and longer lasting, this also degrades their natural antioxidant content and markedly reduces the amount of fiber – remember, those are the two ingredients that make whole grains good for the heart and over-all health.
To make matters worse, the AACC International recently went on to propose a modification of its definition of “whole grain”, which is bad as it is, to allow for this nutrient loss during processing. Continue reading
