A nutrient fiber matrix and associated methods that help control blood sugar levels is described. The matrix can control blood sugar in a variety of ways. In one possible example, the matrix blocks carbohydrates in a manner that reduces the body's ability to take the carbohydrates into its cells. In another example, the matrix acts to increase a person's energy level and feelings of satiety. Thus, the matrix can reduce the person's desire to consume more food and, thereby, help the person to keep from increasing his or her blood sugar levels by eating more. In still another example, the fiber matrix helps sugars to be absorbed over a longer period of time so as to smooth out and prevent spikes in blood sugar levels.
