For heaven’s sake, can we stop pretending that humans can thrive on a vegan diet? Adult humans, who have completed their skeletal and cardiac development, with the money and knowledge to supplement appropriately can stay healthy on a vegan diet. Best case scenario: human children on a vegan diet struggle with pernicious anemia and bone density issues. Our guts can’t extract all necessary nutrients from plants and supplements are an imperfect stop-gap. A baby fares as well as a puppy when vegan.
Don’t know a whole lot about human physiology as I do animals, as a zoology student obviously, but yes in total agreement. Vegan diets are hard, even for humans as omnivores. It requires a lot of money, supplements and for the person to be generally healthy already (if you have any sort of illness or deficiencies being vegan is just not an option).
