A new survey reveals that 82% of Americans who eat hamburgers think that the sandwich is a good source of nutrients.

Researchers with the market research group Mintel polled 1,767 Americans who had ordered a burger from a restaurant in the last three months. 62% of the people said they love burgers—and the numbers were strong even among Millennials, the generation most likely to say that menu healthiness is important to them when they choose a restaurant. Americans’ obsession with burgers isn’t surprising, but the sandwich’s perceived healthiness is, given the fact that the World Health Organization (WHO) recently announced that processed meat is a carcinogen and red meat likely causes cancer.

While burgers are good sources of protein, iron and vitamin B12, they come with a lot of problems, according to nutrition experts—particularly the fatty meat, sugary ketchup and refined grain buns.

The new survey did find that even burger lovers know they could choose a healthier sandwich. People want more chicken and turkey burgers, the survey found, which are considered healthier options.
