Co - the best thing is to agree - because meat the way it is generally raised in this country and cooked IS bad for you. That's the best way to start. By agreeing.
Then educate them about how cows are fed soy and grains which make them grow all sorts of nasty bacteria that isn't natural to them and shot up with hormones and antibiotics so that they can be genetically mutated until they can barely live and then put onto feed lots where they live a horrible existence and then the meat has to be cooked just so that it doesn't kill us. This will open them up, because a vegetarian will be nodding their head up and down now.
Then talk to them about grass-fed animals, what a good life healthy life they lead and how they live and die. Tell them there ARE no studies of eating these kind of animals or especially eating them the way that our ancestors did and thrived on for millions of years - raw and natural. Tell them that they are right and that until people wise up and eat meat the way it CAN be healthy, that they shouldn't be eating it at all.
And then slip in that they also shouldn't be eating irradiated, pesticide ridden, cooked vegetables either.
That ought to give your friend something to think about.
