THE BASICS OF NUTRITION AND GOOD HEALTH Introduction Chronic disease is a leading cause of early death in the U.S. Evidence suggests that lifestyle is a significant factor in this trend. Consuming too many calories or eating too much fat increases risk of heart disease. Of particular concern are eating patterns high in saturated fat and low in whole grains, fruits, and vegetables. The National Institutes of Health recommends that, starting at age 20, everyone should have their blood cholesterol levels measured every five years. A relationship exists between high levels of Low Density Lipoprotein (LDL) and elevated risk of heart disease. Conversely, high levels of High Density Lipoprotein (HDL) are associated with a decreased risk. LDL is the vehicle for unhealthy cholesterol buildup in arteries, while HDL removes arterial cholesterol deposits and transports them back to the liver. Over 97 million adults living in the U.S. are overweight or obese, which has a direct impact on their ability to maintain good health and avoid disease. Body Mass Index (BMI) is a measure used to assess health implications of body fat. BMI is calculated by dividing weight in kilograms by height in meters squared. A BMI between 18.5 and 24.9 kg/m 2 is considered normal. Excess body fat is associated with increased risk of chronic disease. Men with a waist circumference greater than 40 inches and women with one greater than 35 are at increased risk of disease. The incidence of Diabetes Mellitus has grown worldwide in connection with unhealthy lifestyle choices including eating habits and lack of exercise. There are four types of diabetes: gestational, pre­diabetes, Type 1, and 2, each of which has different characteristics and long­term consequences. Gestational diabetes affects about 4% of all pregnant women and , left untreated , results in fat baby syndrome, or a baby that weighs greater than eight pounds at birth. Pre­diabetes precedes Type 2 and is diagnosed when elevated blood glucose levels are found. Type 1 is acute and requires an external source of insulin. Untreated diabetes erodes health and damages tissue.
