That's demonstrably and hilariously false. There is ZERO nutritional need to eat flesh, or any animal products.
You've all been brainwashed since birth by industries that make a ton of money from keeping people ignorant. I know, I was a non-vegan for most of my life, just like most people.
I'm FAR healthier now, as a vegan, than I was as a flesh eater. I don't get sick anymore...almost NEVER, even when I'm around people who are sick.
And as I've mentioned before, in the last 9 years, every single time I've gotten my bloodwork done it comes back near perfect. No deficiencies.
There are tons of people who have cured themselves from all sorts of illnesses by radically changing their diet, to a whole food plantbased diet. It lowers one's risk for cancer and heart disease and other preventable diseases.
The problem is, people LOVE eating dead animals so much that they only want to hear what their itching ears want to hear. And the animal industries fund "studies" to do just that - tell people what their itching ears want to hear.
Meanwhile cancer and heart disease are epidemics in the US, because people don't want to give up their bacon, steak, cheese, etc etc. And they turn a blind eye to the horror show that goes on every day.... and mock people who speak against it. But since this is a messed up, upside-down world, I guess it shouldn't be surprising.
