For the most part, all the food groups contain the six basic nutrients. For example, when you eat a piece of bread, you think you are eating just a carbohydrate. No, it is largely a carbohydrate, but it also contains proteins, fats, water [H2O], vitamins, and minerals.
What about a potato? It is made of carbohydrates, a trace of proteins and fat, vitamins, minerals, and water. What about meat? It is proteins, fat, and a trace of carbohydrates, vitamins, minerals, and water. What about milk? Well, it is proteins, carbohydrates, fats, vitamins, minerals, and water, too. What about chocolate, cookies, cake, or candy? They, too, are fats, carbohydrates, some proteins, and a trace of vitamins, minerals, and water.
Simple carbohydrates are made of short chains of glucose (basically C6H12O6). Breads are made of long chains of glucose. Fructose (another arrangement of C6H12O6) is a simple carbohydrate that God made to fit exactly in the taste bud, which in turn stimulates a nerve ending to send a signal that the brain interprets as “delightfully sweet.” If you were to examine the bloodstream, you would not be able to tell if you had eaten long chains or short chains. Glucose is the sugar form that each of your cells uses for energy. We do not have to eat it—the foods we eat are turned into glucose by the liver. Likewise, your body does not know if it ate honey, unrefined sugar from the sugar cane plant, refined table sugar, or bread, because all the units are converted to glucose in the liver and then transported into the bloodstream in the form of single unit glucose molecules to be used by the body cells. Being overanxious about the source of sugar is part of the bondage of food.
