Take a look at this. It presents an argument that man is marvelously adapted for a vegetarian diet. Primarily fruits.

Osteoporosis, gout, liver failure, kidney disease, constipation, and colon cancer are all consequences of too much meat in the diet.
We must eat the diet for which God made us.
Again the question is not about what is the healthiest diet. It is a moral question. The article says the right diet is not a matter of belief and it sets out to prove humans should not eat meat based on how the human body has adapted over many generations to available foods.
Predators have forward facing eyes. Prey have eyes that see a wider angle to avoid predators. The article showed a human skull compared to a predators and compared teeth. If you compare a human skull to a pure vegetarian skull you will also see a great contrast, with the human appearing to have features of both, indicating we are omnivores.
If you take the adaptation arguement you would be forced to look at indiginous people around the world who are primarily hunters and gatherers. I don’t think there are groves of fruit trees in many areas naturally occurring. You will not find humans swinging from branches eating bananas. You will not find them in plains eating grass. Whereve you find them they eat meat unless they belong to a religion that says it is immoral.
Humans do not need teeth like pure predators, lions and tigers to tear apart their food. We have hands and tools whi h is part of how we are adapted to eat everything.
It may very well be that the ideal diet for best health is vegetarianism. I don’t think that is true, because the long term or life long vegetarians I know are not healthy people. One of my father’s nieces became a vegan. She drove her parents crazy. They knew every salad bar for a 100 miles. She lectured them about how unhealthy it is to eat meat. My father who ate meat daily wryly said to her that people who eat meat do not live long lives. She thought she finally was making a convert not realizing she was speaking with a 92 year old healthy carnivore.
None of this is relevant to the question of morality. Jesus said it does not matter what you eat. It goes in one end and out the other. Nothing you eat can make you unclean (immoral). This is very plain. Peter said don’t eat blood or strangled things, meaning it is ok to eat animals that were shot, stabbed, or clubbed over the head and roasted. Remember the vision he had of all the animals and being told to eat them.
If someone lives on seals, whales and caribou we have no problem with that. If you live on coconuts and taro root and fish don’t worry about it.
If you think that eating or not eating this and that, observing dietary laws will get you to heaven there is a big problem.
The one thing we can say about most of the people in our modern culture who are obsessed with diet is the majority of them do not go into nature and find and produce their own foods. We primarily live in cities and enjoy a broad variety of food at our disposal from supply chain of food coming from various regions around the globe, soya, wheat, rice, fruits and nuts from the north and south and the tropics. People who have to eat what is available, eat what is available and there is no religious or moral implication to this, nothing that impacts the state of your soul, according to our Chuch.
If a person believes eating a chicken is sinful and wants to join a religion that says it is not the case and where the majority of his coreligionists eat chicken without giving it a thought that makes no sense. This was the OPs question. How can I join a religion that allows meat eating, because I do not eat meat, because I think it is wrong?
The answer is DON’T join that religion. Find another one or reconcile your belief that meat eating is immoral. Don’t join any religion whose moral teaching you do not believe.
