Can you provide links to any primary domestic legislation, statutory instruments, regulations, directives, binding international treaties or conventions which prove this is now "set in concrete"?
Without those, it is not law and sounds more like a conspiracy theory.
Suggest you look on the WHO website and the EAT Lancet website and the Lancet website. If you pull up the Apocene Diet report as published and held in archives, then Page 2 shows their corporate sponsoring links and who paid for the report in the main. What is not showing are some of the other links that exist, such as to the Wellcome Foundation, and the Rockefella Foundation. These last two are funding the presentations around the world to various governments such as the UK, EU Commission, Nigeria, India Australia etc.
They wer presenting to the EU comission, the UK Commission on Climate Change the UN General Assembly, and are currently in Mexico and the Phillipines. I am sure there are minutes of these meetings that could be unearthed.
As regards the Law, then yes you are so far correct in that this has not been placed into law per se, but if you read the Apocene Diet report, they make it very clear that this will be required to be in place by 2030. and is their stated goal. So I do not need conspiracy theory since this organisation is being very open about it. Their own words speak volumes.

It is noted as a Fact that the FAO has representatives employed in the EAT Lancet Consortium, and EAT Lancet has employees seconded to the FAO. The same is true of the Oxford Martin School responsible for providing much of the science backing up the Apocene Diet, The same is true for Harvard Medical School, which again provides 'evidence' used in justification. Their science claims do not hold up to scrutiny.
I have on another thread posted the changed Canadian version of Eatwell that define the guidelines for national nutrition, and the sections for meat and dairy that used to be there have been removed. Same with Brazil. USA is considering a Meat Tax, as has also been reported in our press so is the UK. These are not fancyful dreams of mine, the evidence is there on the internet.
May I suggest you take the table in the EAT Lancet diet report and feed it into a nutrition app and then see how it fares in terms of the RDA for micronutrients, and then decide if it is sustainable for humans long term.
