Unhealthy eating and foods continue to contribute to the obesity epidemic the same way that smoking contributes to increase incidences of lung cancer. While food corporations make money off sugar water and snacks, they help to create a vicious cycle of obese consumers who cannot control themselves from opening a pack of potato chips or downing a couple of cheap carbonated sugar drinks.
Health experts want to curb the cost of obesity and diabetes by proposing a tax over junk food, and apply that extra money to subsidize and promote healthier foods such as fresh fruits and vegetables.
