                          Nutrition therapy is an essential component of diabetes management regardless of the cli-
                          ent’s weight, blood glucose levels, or use of medication. People with diabetes generally have
                          the same nutritional requirements as the general population; therefore, dietary recommen-

                          eat less saturated fat and cholesterol, eat more fiber and less sodium—are also appropriate
                          for people with diabetes. Because coronary heart disease (CHD) is the leading cause of
                          death among people with diabetes, it makes sense that nutrition recommendations issued
                          by the ADA to prevent and treat diabetes are remarkably similar to recommendations put
                          forth by the American Heart Association (AHA) for the primary and secondary prevention
                          of CHD (Chapter 20). Nutrition recommendations for diabetes management are summa-
