Not everyone can eat a pure vegan diet. We are omnivores. We don’t get to pick, we must eat it all to stay healthy.
So do it. While some people would argue vefpganism is ideal, the important part is “less meat”, especially less beef. I’d give kudos to anyone who eats one less beef meal per week: chicken is much easier in the environment than beef, or ne less meat meal,
The word Ideal is very generic. Ideal to who? What is ideal? Your health? The climate? Your bowel movement?
Meat contributes a ton of CO2. 15% of global output in just beef alone. Pork and Chicken is better.
Instead of pickering over words we could just acknowledge the underlying facts.
Those who can, and most people in western industrialized countries can, should reduce their meat consumption. For most of them veganism is a viable option, especially as there is easy access to doctors checking as well as supplements if there is difficulties.
There is no intrinsic need for animal protein or fats for a healthy diet.
Everyone needs nutrients they can digest. The source doesn’t matter under these conditions. Excluding rare medical cases, everyone can get all required nutrients from non-animal sources, ergo everyone can have and live a perfectly healthy life on a vegan diet.
Meat has more than just protein. It has so many micronutrients that your body needs that you would have to take a shit ton of supplements to just come close to it. Sure, you can survive without those micronutrients. But why go through all the trouble?
