A large study done on a large dataset including the Nurses Health Study and the Health Professionals Follow-Up study found that eating fast foods and fried foods away from home was POSITIVELY coorelated with surviving to and beyond 70 years of age, being free of chronic disease, intact mental health, intact physical function, and intact cognitive function.

Now I'm sure you've always believed that eating fast foods and fried foods was bad for you.

So, presuming the study was done correctly, and presuming that fast foods and fried foods are indeed bad for you as we have always believed, can anybody explain the result?

I can think of at least two possible explanations (confounders), but I'd like to hear what other people think first.

1. Positively correlated doesn’t say too much - how strongly? Need a number.

2. Of course all of those healthy traits

would correlate positively and strongly. They're all different traits of "health"

3. Sounds like the correlation is frequency of eating out and some rating of "healthiness" (longevity, duration free of disease, etc). I think this is mainly a case of people who are healthy are also ones who are willing and able to get out, do things, travel, and maybe offer themselves a burger and fry treat. If you're unhealthy, you likely don't get out to do this.

And that's the kicker, the study showed eating fast food AWAY from home had this positive correlation. I'll bet anything it would be negative for eating fast food at HOME. The study seems to really be correlating (a) getting out of the house and doing things with (b) health: not fast food consumption and health.
