Before you enjoy a baseball game under the warm sun this summer, remember that Justin is asking you to stop eating hot dogs.

In 2011, the World Health Organization (WHO) concluded that processed meat of any kind was a Class 1 carcinogen (the same classification as cigarettes). If a person eats 3.5 ounces (the size of one jumbo hot dog) of processed meat every day, their risk of colorectal cancer will be 36% higher than someone who eats no processed meat. If they eat 7.0 ounces of processed meat every day (49 ounces per week), their risk will be 72% higher.
