Hmm!! I've been a vegetarian now for almost 40 years. It would have been more, but my husband made me eat meat when I became a Christian and married him. I got sick after a few years, and he "allowed" me to go back to being a vegetarian.
When he got diagnosed with pre-diabetes, we went to a provincial workshop on the best diet to eat. It is also the heart smart diet.
It consists of high fibers and grains that are unprocessed. No sugar and limit red meat to once a week or less.
My husband now regrets we did not follow my "hippie" diet which in fact, was eating foods in their most natural form as possible. The form that God created food! Not animals from feed lots, farm fed fish with viruses and parasites, etc. Vegetables, and fruits and combining vegetable proteins. And lots of interesting spices and things like that. I cannot digest red meat at all, so I stay away from it, and despite my health issues, I have a healthier heart than most people my age who are supposedly "healthy."
We won't even get into GMO's and poisons and Monsanto and how our food is shipped from places so far away it loses most of its nutrition.
Also, I am in NO WAY a SDA, but population studies show they are healthier than their counterparts that eat meat.
I do not condemn anyone that eats meat, but it is a waste to the planet, and an unhealthy way to eat.
No scriptures this time, just my personal experience. You really don't meat to be healthy, kosher or otherwise, and in fact, you may find yourself healthier than a person who eats meat if you don't eat meat.
As for poop, I put manure on my garden and my plants are healthy and happy. So I guess in the ecological scheme of the planet, what comes around goes around! LOL
