The unhealthy user bias suggests that individuals who disregard mainstream health advice and consume red meat may also engage in other risky behaviors.

“well is it the hamburger that's not beneficial for them or is it the fact that they're not exercising or not seeing their family or not doing things not going to the doctor as often they should be in getting regular screening this is the unhealthy user bias I would argue that's been associated with red meat”

“in the Western world only not in Asia we can talk about the Asian Studies as well in the Western war in the Western us in epidemiology when we do surveys of people and these are epidemiology they're prospective or retrospective cohorts where they look at people and they say what and we're gonna take a survey of people and ask this set of people what they ate for the last 20 years and they look at that group of people and in the group of people in who provide information about what they ate in the last 20 years they find epidemiologically that those who ate more red meat had more incidence of heart disease now that is epidemiology and this is something I I said many times in the podcast with lame it is confounded by what is called healthy user bias”

“who has eaten red meat for the last 70 years people who disregard health advice they are more likely to smoke more likely to drink more likely to be obese more likely to ride motorcycles i'm kind of joking about that one but you get the idea more likely to have many other risky behaviors because they are disregarding quote mainstream health advice and eating red meat this is what is called the unhealthy user bias”

“who eats more red meat this is where the unhealthy user bias comes in people that eat more red meat are people who disregard health advice in general”

“i think it is much more likely that it is the latter case because of unhealthy user bias”

“The flip side of that is unhealthy user bias, which is when we study things like the correlation between red meat and cardiovascular disease. Because who tends to eat red meat, generally speaking? ... people that eat red meat are generally unhealthy, okay?”

“these are observational studies and could they be confounded by healthy user bias and unhealthy user bias”

“What I'm describing in an observational study from which you cannot draw causative inference so meat doesn't cause cardiovascular disease why do we even think that in the first place well because of these observational studies ignoring the ones in Asia and probably because the saturated fat in red meat raises LDL”

“this is unhealthy user bias and healthy user bias respectively or what I'm describing in an observational study from which you cannot draw positive inference”
