Unhealthy eating and physical inactivity are leading causes of death in the U.S. Â
Unhealthy diet contributes to approximately 678,000 deaths each year in the U.S., due to nutrition- and obesity-related diseases, such as heart disease, cancer, and type 2 diabetes.1 In the last 30 years, obesity rates have doubled in adults, tripled in children, and quadrupled in adolescents.2, 3, 4

The typical American diet is too high in calories, saturated fat, sodium, and added sugars, and does not have enough fruits, vegetables, whole grains, calcium, and fiber. Such a diet contributes to some of the leading causes of death and increases the risk of numerous diseases5, including:
heart disease;
diabetes;
obesity;
high blood pressure;
stroke;
osteoporosis;6 and
cancers, including cervical, colon, gallbladder, kidney, liver, ovarian, uterine, and postmenopausal breast cancers; leukemia; and esophageal cancer (after researchers took smoking into account).7

Unhealthy eating habits and inactivity affect quality of life and cause disabilities
Few recognize that unhealthy diet is a leading cause of disability. Yet unhealthy eating habits and physical inactivity are leading causes of loss of independence:
Diabetes is a leading cause of blindness and amputations. Roughly 73,000 people have lower-limb amputations each year due to diabetes.8
Bone injuries due to osteoporosis are most likely to occur in the hips, spine, and wrist. Even just a slight fracture in these areas can result in loss of independence. Twenty percent of seniors who break their hip die within just one year. Those who survive often require long-term (nursing home) care.8, 9
Heart attack or stroke can result in difficulty with everyday activities—such as walking, bathing, or getting into or out of bed—or cognitive impairment.10
Number of Americans Living with Diseases Related to Diet and Inactivity Â
Obesity1178,100,000
High Blood Pressure1266,900,000
Diabetes1329,100,000
Heart disease1426,600,000
Cancer1420,073,000
Osteoporosis159,900,000
Stroke146,400,000
Obesity rates are skyrocketing
Over two-thirds (67.5%) of American adults are overweight or obese.2
Obesity rates in children have tripled over the last three decades, and one in three children and adolescents 2-19 years old is overweight or obese.4, 16

Costs of Diseases Associated with Diet and Inactivity*
Diabetes8$245 billion
Cancer18$216.6 billion
Coronary heart disease9$204.4 Billion
Obesity20$190 Billion
High blood pressure19$46.4 Billion
Stroke19$36.5 Billion
Osteoporosis9$19 Billion
* Estimates of annual direct + indirect costs for diseases overall (including portions caused by factors other than diet and physical inactivity), except for the figure for obesity, which is an estimate of direct (medical) costs only.
Health care costs $8,900 per person per year.21 Â According to the Centers for Disease Control and Prevention (CDC), a 1% reduction in dietary health risks such as weight, blood pressure, glucose, and cholesterol risk factors would save $83 to $103 per person per year in medical costs.22
