in a nutshell: keep an eye on the overall quality of the meat everything. Don´t eat meat everyday too much, but if so, treat yourself with some high quality meat exercise
This is how I see food. Everything of a bad quality can cause problem, particularly in excess. And seeing that you cannot objectively analyze the quality of a product, without going through scientifical experiments that noone bothers except the lobby groups, you are better off just eating whatever you like.
Lobby groups are the ones providing scientific knowledge? This is a deeply misinformed post.
And you can see clearly when food is rotten, that's objectively true. If it makes you sick, it was objectively bad.
The smaller objective facts are out there, even if they are not immediately observable. If we know for a fact that ingredient X causes something bad, then a food product with ingredient X is objectively "bad" or worse than a identical product without it. There's no subjectivity in disease statistics.
And you can check the amounts of sugars, salt and fats and many other things right on the tin.
And even premium stuff can cause problems, especially in excess.
Eating X and then exercising won't fix everything. Many foodstuffs do more in your body than just give energy.
Fructose is one example of this. It's sugar like the rest of them, but it's almost entirely metabolized in the liver, causing fatty liver disease, among other unwelcome changes in normal body function.
You're absolutely right in not worrying too much about eating meat though.
But whatever you choose to eat and think, at the very least don't equate scientists with lobbyists, please.
