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. In the last 30 years, obesity rates have doubled in adults, tripled in children, and quadrupled in adolescents.
Count till 687,000 and see how long it takes. That is a LOT of unnecessary deaths.
