Frequent burger consumption may up the risk of asthma, according to a study of 50,000 children. Specifically, children who eat three or more burgers per week have an elevated risk of asthma and wheezing. Conversely, a Mediterranean diet high in fish and fruit appears to prevent asthma.

Curiously, a diet high in any type of meat was not linked with asthma. Consequently, the study’s authors suggest that the link may be due to lifestyle factors, rather than beef itself.
