What makes you think that processing food through an animal is healthier than through a factory?

You have to compare the actual nutrients contained in the product to draw any conclusion about health effects, and the macros are fairly similar for the plant-based versions compared to a given meat product.

The average person (in developed countries) eats significantly more meat than the recommended upper limit by nutrition organizations.

If you just go by the naturalistic argument, you’d conclude that processed drinking water is worse than untreated water, and that vaccines are worse than “perfectly natural” diseases. It’s a common logical fallacy.
