I'm in Brazil so... Hehe, definitely no meat for me. Even if the product says 'free-range' on it, I don't trust it here.
I'd heard about the soy-product EDC issue, but when doing a bit of research, it seems only particularly worrisome for people going through critical developmental stages... That is, teens and younger, especially infants. Not sure though... I only have it with my breakfast every morning, and it is fortified with all sorts of good minerals. Haven't noticed any adverse affects thus far...
GMOs: I've given up on avoiding GMOs... First, they're everywhere ... Second, after a bit of research, I don't trust the organic movement any more. They're now just as bad as the biggest food industries, exaggerating and sometimes outright lying about the harm GMOs cause. I think the worst part of it is exactly as you say... The long-term affects... Eventually, we'll find out, I guess. They've been around for quite a few decades already. Difficult to study though, like all nutrition. I don't envy your job as a nutritionist ;P
In-vitro meat: As far as I've read, it seems safe. Biologically identical muscle tissue. And I'd agree, certainly healthier than CAFO animal meat. Depends on the company practices though, I suppose. In the end, greed trumps all, so if there's a way to "grow" the meat faster and cheaper, it'll be done, no matter if there's a small health risk.
I thought South America had good meat. Is that not so? Or does it depend on which country?
My bottom line as a nutrition coach is usually, how natural is it? But it's not always as simple as that, and everybody's needs are different. So we need to be open minded about how to meet each person's needs in the most practical way. And sometimes that might mean eating foods that wouldn't be my first choice.
So I take all your points above about how you choose to meet your needs. You just do the best you can, and then don't stress about it!
