Do Americans on "normal" diets have deficiencies in minerals and vitamins so that these minimal differences FloraSpring in a slice of bread make a difference? All of the recent data on vitamin and mineral research say, NO. Unless a person is pregnant,or an alcoholic, on some very unusual diet, or has an underlying gastrointestinal disease our normal foods have adequate amounts of minerals and vitamins. Extra vitamins and minerals are not needed from a vitamin pill and certainly not from a slice of two of bread which supply so little compared to our requirements. If it's not the vitamins, minerals, carbs, protein, fiber or fat, maybe its the glycemic index that is different among the breads.
The Glycemic index (GI) is a measure of the effects of carbohydrates on blood sugar. Carbohydrates that break down rapidly during digestion releasing glucose rapidly into the bloodstream have a high GI; carbohydrates that break down slowly, releasing glucose gradually into the bloodstream, have a low GI. For most people, foods with a low GI have significant health benefits. The concept was developed by Dr. David J. Jenkins and colleagues in 1980-1981 at the University of Toronto in their research to find out which foods were best for people with diabetes. A lower glycemic index suggests slower rates of digestion and absorption of the foods' carbohydrates and less effect on insulin and the conversion of carbs to fat. For example chocolate cake has a glycemic index of 80-100, candy 80 plus, vegetables less than 20.
It looks like that white, whole wheat and whole grain breads are about the same. Is that true? There is very little differences between a slice or two of white, whole wheat or whole grain bread in terms of calories, protein, carbs, fiber, vitamins, minerals and glycemic index. Whether a turkey sandwich with lettuce and tomato is made with white bread, whole wheat or whole grain should not be much of an issue for the dieter. There are far more important issues to be concerned about.
