         | 
         | Of the total land area of the contiguous 48 states, ~45% is
         | used for animal ag. This includes: Land for grazing livestock
         | at ~35%. Land for crops going specifically to animal feed at

         | There are plenty of vegans with Celiacs who manage their iron
         | adequately. But even if you're one of those cases where iron
         | needs to be supplemented, even IV - why not? If you disregard
         | all the arguments against beef or animal products in general
         | it's easy to make the argument that beef would be the best
         | solution.
         | 
         | This reads like appeal to authority (the nutritionist) but a
         | lot of nutritionists take the easy road ("just eat beef") or
         | aren't good at all (haven't kept up with research). That's true
         | of the majority of doctors and the majority of programmers
         | (something people here will be able to relate to in case they
         | haven't realized how useless most doctors are). I've been in
         | and out of hospitals for several relatives for years and have
         | heard doctors tell me outright falsehoods that show they have a
         | only basic understanding of something. That makes sense since
         | those doctors must know about so much more than the patient
         | (thousands of diseases, lots of scientific knowledge about
         | biology) but with a depth-first search into a topic you can
         | spot how most of them have either stopped reading new studies
         | or have lost their motivation to explore all option or have
         | just stopped caring for providing the best kind of care. I hope
         | people here don't have to go through what I have. That was a
         | bit of a tangent, but I already wrote it so I'll keep it as a
         | mini-rant.

         | > Beef is kind of an important thing in our diets, that's all.
         | Now that I'm back to a more normal level I'll go back to eating
         | less of it, but I am now very conscious how important red meat
         | is in a rounded diet.
         | 
         | That's not really true. I'm sure you could ask vegans or
         | vegetarians or Hindus or anyone who doesn't eat beef but has
         | Celiacs and you'd get a whole bunch of options for managing it.
         | Sure, you'll find ignorant people who think eating fruits all
         | the time is enough but that's the same kind of carelessness
         | that leads to non-vegans eating the standard Western diet all
         | the time or doing other basic mistakes.
         | 
         | The same is true for almost everything. Almost nothing is "an
         | important thing in our diets". People live without nuts or
         | fruits or vegetables or legumes or meat or eggs or dairy (not
         | all at once, of course, although I wouldn't be surprised if
         | someone managed to avoid all these) and are able to manage
         | pretty much any disease other groups of people can manage.

         | > calories are only part of the picture when it comes to food

         | True, people should care about the macros and micros. But with
         | the internet it's trivial to do so both wrt learning what does
         | what and how much is needed, and to track how much one eats
         | from each.
