An interesting book entitled WHEAT BELLY by cardiologist William Davis makes a similar point regarding the newer strains of wheat grown since the mid-sixties. He discovered by accident in his practice that when his heart patients went on wheat-free diets, their heart condition dramatically improved. He set out to find out why and the book is the result.
Dollars to donuts his patients lost weight. Eliminate all bread, pasta cakes, cookies, donuts, etc. from your diet and you will most likely lose plenty of weight. Lose weight and your heart condition improves.
It's not rocket surgery.
