Why is it your opinion (and that is all that it is) that red meat is bad for you?
Everything I communicate is my opinion. This statement is useless at best, absurdly condescending at worst.
But since you asked, red meat has fewer vitamins and minerals than vegetables, with a lot more calories, is less likely to make you feel full with the same volume (contributing to overeating), typically has all the other problems with fat and cholesterol, often has more contaminants, is much more difficult to process safely from slaughter to plate, contributes more pollutants to the environment along the way, and has been indicated in fueling gut bacteria unfriendly to cardiac health.
Most of that is pretty well known, but the cardiac research is recent.

Opponents to the conclusion that red meat is implicated here argue that the bacteria is the problem. Those who think the research implicates red meat point out that red meat creates the environment for the bacteria to thrive, and you can't exactly wipe out all your gut bacteria.
I eat red meat because it's freaking delicious, but I don't think it's good for me. In moderation, it can be not a big deal, maybe. But even "not a big deal" is not the same as "good for you."
I still disagree.
Red Meat is Very Nutritious
Meat
Red meat is one of the most nutritious foods you can eat.
It is loaded with vitamins, minerals, antioxidants and various other nutrients that can have profound effects on health.
A 100 gram (3.5 ounces) portion of raw ground beef (10% fat) contains (3):
Vitamin B3 (Niacin): 25% of the RDA.
Vitamin B12 (Cobalamin): 37% of the RDA (this vitamin is unattainable from plant foods).
Vitamin B6 (Pyridoxine): 18% of the RDA.
Iron: 12% of the RDA (This is high quality heme-iron, which is absorbed much better than iron from plants).
Zinc: 32% of the RDA.
Selenium: 24% of the RDA.
Then there are plenty of other vitamins and minerals in there too, in smaller amounts.
This comes with a calorie count of 176, with 20 grams of quality animal protein and 10 grams of fat.
Red meat is also rich in important nutrients like Creatine and Carnosine. Non-meat eaters are often deficient in these nutrients, which can have negative effects on various aspects of health, including muscle and brain function (4, 5, 6).
Grass-fed beef is even more nutritious than grain-fed, containing plenty of heart healthy Omega-3s, the fatty acid CLA, along with more Vitamins A and E (7, 8, 9).
Bottom Line: Red meat is very nutritious, especially if it comes from animals that have been naturally fed and raised. It’s a great source of protein, iron, B12, Zinc, Creatine and various other nutrients.
