Epidemiology studies linking higher meat consumption to increased cardiovascular disease risk may be confounded by unhealthy lifestyle choices.

“there was recently one in the journal of the american medical medical association kind of on the flip side showing the more meat you eat the more risk you have of cardiovascular disease and again it's an association these are not they didn't take a group of people and feed them more meat and then see more cardiovascular disease they took a group of people and they surveyed them and they said how much meat did you eat over the last 10 years and they looked at the people who ate the most meat and they had more cardiovascular disease so this is potentially confounded by unhealthy user bias”
