As others have commented, it's hard to draw conclusions from such a biased sample set. To truly determine causation we would need to run a double blind experiment.

Ah!

I know nothing about being blind, but maybe there is some confounding lifestyle factor for blind people.

Well, the blind would not be as tempted by a McDonalds advertisement, for starters

That's an interesting point. A huge part of food is visual cues-- without those there are that many fewer triggers to eating processed and fast foods

Olfaction ? I can make your stomach gargle instantly. And blind people are said to have heightened senses.

I mean, who doesn't hear the "I'm lovin' it" jingle and not want a highly processed not real meat patty shaped something on a bun?

> not real meat patty

Since when? Last time I checked they're selling real meat from animals that lived in an absolute horror show for their short life, which came to a close in the slaughter house where they're drowned in CO2.

I mean, if you want to consider other animal parts used as filler as real meat, then sure. Personally, I don't.

There are continuous audits wrt the meat to make sure exactly that doesn't happen.

Show me a single article which reports with proof that McDonald's accepted this kind of meat at scale.

You won't find it because they don't have to. They're paying cents per pound of meat because the meat industry has gotten extremely efficient at producing it.

Animals are artificially inseminated whenever they're not pregnant using sperm provided by a lab, fed soja and corn to maximize growth etc.

There are a lot of issues with the food, but the "meat quality" is likely higher then the stuff you buy at a supermarket.

You can literally go to court if what you claim is provable as they're making clear statements that its 100% beef. There are no asterisks on that, it is beef as defined by law.

McDonalds is the company that previously trademarked the term 'real beef' so they could mix filler in with it and still sell it as 'real beef (tm)' .. are they now that loophole has been plugged, do you think they're incapable of shaving the quality down in as many other ways as possible?

That particular hypothesis could be tested reasonably well by comparing the BMI of the two groups.

Maybe some blind hackers could share their view in that
