Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals.

Here is the Vegan Society's definition of veganism:

This philosophy is contrary to Scripture which clearly teaches that mankind has a right to eat animals.  It is therefore not compatible with Catholicism.  Also, vegans typically believe a lot of nonsense about environmentalism including that stopping eating animals will save the world.  Most of them are convinced that this is the ideal healthy way to eat.  There have been many cases in the news of children getting sick or even dying because there parents have fed them a vegan diet.  In my experience, it is like a religion for them and it is not possible to reason with them.


I am not surprised that you have not met any trad Catholics who accept these beliefs.  Catholicism is the religion of truth and veganism is about one lie after another.

There are no health benefits to a meatless diet.  There are benefits from changing from the standard Western diet which is highly processed and far too high in sugar.  Eating primarily fresh fruits and vegetables is better than that, so people may see an improvement in health.  They would, however, be even healthier if they ate lots of unprocessed meat.

If you want to be like Adam and Eve in the garden, then I suppose you want to be a nudist too. Or maybe when it comes to clothing you realize that this is not a good basis for our life choices, since we are not Adam and Eve in the garden. What does apply to us is the explicit instruction God gave to Noah in Genesis 9:

1 And God blessed Noe and his sons. And he said to them: Increase and multiply, and fill the earth. 2 And let the fear and dread of you be upon all the beasts of the earth, and upon all the fowls of the air, and all that move upon the earth: all the fishes of the sea are delivered into your hand. 3 And every thing that moveth and liveth shall be meat for you: even as the green herbs have I delivered them all to you.

And this is confirmed in the New Testament in Acts 10:

[11] And he saw the heaven opened, and a certain vessel descending, as it were a great linen sheet let down by the four corners from heaven to the earth: [12] Wherein were all manner of fourfooted beasts, and creeping things of the earth, and fowls of the air. [13] And there came a voice to him: Arise, Peter; kill and eat.

If you want to take care of your body appropriately then your diet should include meat.  If you stubbornly cling to your mistaken belief that a meatless diet is healthy and continue to eat that way, at least don't call yourself vegan.  That is the name of a non-Catholic philosophy and it causes scandal when you speak as if it were acceptable for Catholics.

So long as diet and health does not become an idol in one's life.
