I'm vegan but I'd never make stuff up. Notion of food being unhealthy or healthy is borderline orthorexic. Saying that red meat is unhealthy is vague. There's no concept in science that categorizes food as either healthy or unhealthy. There has been no strong evidence that diets containing meat are unhealthy.

As much as I'd like everyone to severely decrease their meat consumption and eventually stop using all animal products I won't scare them with shaky facts.

Would USA population benefit from eating less food, definitely. Are epidemiological studies strong enough evidence for diet related health benefits? No.

HN is full of orthorexic hivemind demonizing ingredients like sugar, cholesterol, fat, meat or whatever.

There are plenty of valid, rational reasons to stop eating meat. If one is in good health then health is not a valid reason.
