Document Summary
What are carbohydrates: one of the three macronutrients, an important energy source, especially for nerve cells, composed of the atoms carbon, hydrogen, ozygen, good sources include fruits, vegetables, grains. Glucose: the most abundant carbohydrate, comes from plants photosynthesis, the preferred source of energy for the brain, an important source of energy for all cells. Simple carboydrates contain one or two molecules: monosaccharides contain only one molecule. Plants store glucose as polysaccharides in the form of starch. Our cells cannot use complex starch: glycogen. Stored in our bodies in the liver and muscles. Not found in food and therefore not a dietary source of carbohydrate: fiber. Functional fiber: nondigestible form of carbohydrate with known health benefits, which is extracted from plants andadded to foods. Cellulose, guar gum, pectin, psyllium: total fiber= dietary + functional fiber. Dietary fiber is also classified by solubility.
