There's not magic shit in meat, it's mostly water and amino acids and the remaining fraction is mostly bad for you. (I eat meat all the time, but we know a lot more than barely anything about nutrition. Figure out vitamin RDAs in milligrams if you want an example)
I'm shocked that people seriously believe that the fundamentals of nutritional science are a virtual mystery or has enough "wiggle room" to make ridiculously broad claims about diet necessities. We know almost exact micrograms of iodine we need per day to be healthy. We have a pretty great idea of what the body needs to function optimally and are getting a clearer picture every day. Is this why GMOs became such a par…
You are right we have some pretty good information on deficiency problems with key things like iodine, B12 (topical) etc. We have much less understanding of how even dietary source actually work even with some key nutrients outside of lab conditions, and beyond that dietary nutrition is absolutely full of handwaving. We are nowhere near a clear picture; lot's of people will tell you we are but they still contradict each other regularly. This is not a mature science.
