The United States Surgeon General's 1988 report on nutrition and health, based on over 2,000 studies, concluded that illnesses of over eating and nutritional imbalance are the leading causes of death in North America. Numerous epidemiological studies point the link between diets high in saturated fats and cholesterol and increased risk for atherosclerosis and coronary heart disease. The "silent killer," or elevated blood pressure, has been linked to high sodium intake (some 20% of the US population is predisposed to retain sodium and as a result hold water), and it is believed that 30% - 50% of all cancer is diet related (Hoeger, 1991). In addition, poor nutritional habits may also lead to obesity, diabetes mellitus, and osteoporosis.
