What you are describing with meat is what happens not long after eating too much. In fact, other than lactose intolerance, it is rare to have issues that are not due to eating too much. Sure, there is a disease you can get from ticks, that can make you unable to process a protein, found in all animal products. Friend of mine has it. However, rare. Far more people have type one diabetes precluding them from eating a bunch of vegan friendly food.
That vast majority of people have bad reactions to hurting others though.
Quite a lot of people experience physical discomfort or pain from eating the things you listed.
A good portion of the world is lactose intolerant, justtpo point out an obvious one.
Meat can cause a “spike followed by a come down” effect somewhat similar to sugar in some people.
But what I think happens is that people dont make the connection between how they feel and their diet.
