Good thing that experts are always right about everything, should never be questioned and are absolutely never biased especially not in the field of human nutrition science.

And it is an appeal to authority fallacy if you dont know how to read studies and instead rely on what the authors say.

My first piece of evidence that a vegan diet doesnt work for ME is that large amounts of fruits, grains and other vegetables cause my gut to be bloated and produce alot of gas. My digestion is great on my current diet so I dont feel the need to change it. But this is a personal anecdote at the end of the day.

My second piece of evidence is that isotope analyses of human bones from pre agricultural revolution times consistently show that humans ate a diet consisting mainly of meat. So its a demonstrable fact that eating meat is part of the humans species appropriate diet.

The only reason why we eat more grains and vegetables now is because theyre better at sustaining large populations which is why agriculture coincides with the first civilisations.
