Preview Besides controlling hyperglycemia, a high-carbohydrate, high-fiber diet can lower serum lipid levels notably. Thus, the risk of cardiovascular disease, which is elevated in diabetic patients, is reduced. The authors describe the benefits and review practical aspects of managing diabetes the high-fiber way. They also provide a sample meal plan for home use.

More than 11 million people in the United States have diabetes. 1 The incidence will probably increase by about 500,000 new cases yearly because obesity, a major contributing factor to diabetes, is becoming more common. 1 This increase coupled with the declining death rate from diabetes will greatly add to the number of diabetic patients requiring medical care in the next decade. Treatment of diabetes and its ophthalmic, neurologic, and cardiovascular complications is costly, totalling an estimated $20.4 billion in 1987 for direct and indirect costs. 2 Effective, economical treatment could significantly lower these costs. Although diet is considered the cornerstone of diabetes treatment, insulin and drug therapy often take the leading role. Of the $1.7 billion spent in 1987 for outpatient care, 47% went for insulin and oral sulfonylureas.2 Ironically, use of excess exogenous insulin can suppress endogenous secretion and worsen insulin resistance. 3 Oral sulfonylureas do increase insulin secretion and sensitivity, but they are often used as a substitute rather than an adjunct to

diet and exercise. 4 Diet therapy is cost-effective, well-tolerated, and safe but is often neglected because of the time, education, and behavior modifications required.

Goals in management of diabetes In the past, management of diabetes focused primarily on control of blood glucose. Today, physicians know that control of lipid levels is also vitally important. Death caused by heart disease occurs two to three times more often among persons with diabetes than among those without diabetes.4 Hypercholesterolernia is the major risk factor for atherosclerosis, and average serum lipid levels are higher in diabetic than nondiabetic persons. 5 The risk for heart disease increases with each additional life-style risk, such as obesity, hypertension, and tobacco use. Figure 1 shows how diabetes contributes to atherosclerosis. Hyperlipidernia, glycosylation of lipoproteins, platelet dysfunction, arterial wall changes, hyperinsulinemia, hypertension, and obesity combine to accelerate atherosclerosis in diabetic patients.6 Achieving and maintaining

desirable serum lipid levels have emerged as primary goals in management of diabetes. Evidence indicates that for every 1% reduction in plasma cholesterol level, there is an estimated 2% reduction in coronary artery disease. 7 Classification of cholesterol levels in adults from the National Cholesterol Education Program is summarized in table 1.8 Total cholesterol and low-density lipoprotein (LDL) cholesterol levels that are considered borderline for nondiabetic persons are probably of concern in diabetic patients. Major cardiovascular risk factors in diabetic patients are hypercholesterolernia, hypenriglyceridernia, hypertension, and smoking. Obesity, inactivity, and poor stress management are secondary factors that should also be addressed. Thus, at the University of Kentucky Metabolic Research Group, Lexington, management goals for adult diabetic patients are the following: • Fasting plasma glucose less than 150mgldU • Glycosylated hemoglobin (hemoglobin A 1J less than 7% • Serum cholesterol less than 200 mgldL • Fasting serum triglycerides less than 250 mgldL • LDL cholesterol less than 130 mgldL • High-density lipoprotein (HDL) cholesterol: in men, more than 45 mgldL; in women, more than 55 mgldL continued

Many factors (eg, hyperlipidemia, platelet aggregation, dysinsulinemia) work together to accelerate atherosclerosis in diabetic patients.

Fiber and lipid control When studying the effects of high fiber intake on glycemic control, we soon discovered that fiber also lowers serum lipid levels. In our studies, a high-carbohydrate, high-fiber diet lowered serum cholesterol values an average of 30% for type I diabetes and 24% for type 11 diabetes. 6 Fasting serum triglyceride levels decreased an average of 5%, although the responses varied. Compared with a high-carbohydrate, low-fiber diet, a high-carbohydrate, high-fiber diet reduces serum triglyceride levels. 4 The diet developed for home use provides 55% to 60% of calories as carbohydrate and 25 g of dietary fiber per 1,000 kcal. Long-term use of such a diet maintained serum cholesterol values 15% to 20% lower

and serum triglyceride values 40% lower than initial values in a patient who was on a traditional diabetic diet. 6 High-fiber diets also lowered blood pressure 10% in diabetic men compared with controls.6 Water-soluble fibers are particularly effective at lowering lipid levels. When hypercholesterolemic men were followed up for 99 weeks after starting a high-carbohydrate, highfiber diet supplemented with oat bran or dried beans, their total

Weight loss is another benefit of a high-carbohydrate, high-fiber diet. Obesity contributes to both hyperglycemia and hyperlipidemia. By slowing gastric emptying and the recontinued 159

Cereals and beans (eg, kidney, pinto) are good sources of water-soluble fiber.

lease of gut hormones, a high fiber intake helps increase satiety. Also, high-fiber foods are less energy-dense and take longer to eat. When the amount of carbohydrates and highfiber food is increased, intake of fat and cholesterol is automatically reduced by displacement. Additionally, recent evidence has more clearly defined the role of fiber in the prevention and regression of colon cancer. 16

High-carbohydrate, high-fiber nutrition plan

Our high-carbohydrate, high-fiber diet for home use provides the following: • 55% to 60% of calories from carbohydrates (about two thirds from complex carbohydrates) • 15% to 20% protein (minimum of 45 g daily) • 20% to 25% fat or less (10% or less as saturated fat) • 200 mg or less cholesterol daily (100 mg/1,000 kcal) • 40 to 50 g total dietary fiber daily (25 g/1,000 kcal) • 10 to 15 g soluble fiber daily The high-carbohydrate, highfiber exchange system (table 2) simplifies diet calculation. 17 The cereal and bean groups help to ensure adequate intake of water-soluble fiber. Table 3 illustrates a typical highcarbohydrate, high-fiber maintenance menu, and table 41ists selected sources of water-soluble fiber. Although food sources of water-soluble fiber are preferred, fiber supplements may be advisable for certain patients, such as those with or at risk for heart continued on page 164
