Changing the idea of the food we eat is going to be challenging. For years, we have been told that grains of any kind are considered equal. But newest research is saying this is not true all grains are not considered equal. Farmers grow amazing grains but the Milling Industry take the simplist pure form grain and makes it into powder (lifeless powder). Why? Because each part of the whole grain has value and the more it is pulled apart the more money they make. Then to make them more money they bleach it so they can mill it and ship it out right away.
The bleach they use (alloxan) has been proven to kill off the beta cells in the pancreas (basically what creates diabetes). That processing makes the flour act like sugar in the body. The body recognizes this white powder as sugar so it is not good for diabetics so people who need to avoid sugar need to avoid bleached white flour.
Try starting slowly in removing flour from your diet. Don't coat meat with flour before cooking - try corn starch. Don't thicken gravy with flour use corn starch.
