Without listening to the discussion, I'll give my (undeterminably but probably undereducated) opinion on the matter... Cause this is definitely a lamb chopping
Once upon a time there was a fat little kid, teenager actually but 'kid' just sounds better - he was quite overweight and very unathletic, one day he started to eat less processed food and he started feeling better... And then he became a vegetarian, and then vegan, and finally he ate mostly raw. And closely paid attention to what he ate. After a year went from 214lbs to 145lbs, he looked and felt great!
He started exercising, began to run, within 6-7 months he ran his first race, a marathon. Around 9-10 months he ran his second race, an ultra-marathon. He was on top of his game, or was he?
(this is where you expect the plot twist) Yeah, he pretty much was doing great.
Only once did a massage therapist say that his ligaments were undersized, but what does she know anyway? ...However that comment left enough of an impression (more like planted a seed of concern) that maybe this kid (now in his 20's) should reintroduce animal products into his diet... So he did, and here's where the story thickens...
With bone broth and stews. Still, nothing changed. I feel the same.
So what is the moral of MY story? That we can and have survived on a wide verity of foods, and that we thrive on anything *well balanced and varied* that your great-great-grandparents would have eaten. It's what we've developed in the last 100 years that is making people sick.
But if you were to ask me "what diet do you believe is ideal?" I would introduce you to my own, which is what wannabe eccentric people like myself do...
I call it the 1882 diet.
If it didn't exist in 1882, don't eat it. Then I use those numbers again and say eat approximately 18% fauna product, and 82% floria product by mass.
I'll leave it at that, and listen to the podcast.
