Why after thousands of years of consuming alcohol and bread there are still people who are allergic or intolerant to alcohol and gluten?
In: 12
Nobody is allergic to alcohol… some people do have a genetic trend of not producing an enzyme or producing a less effective one, but that’s not an allergy.
Gluten is an autoimmune response just like allergies. Allergies are very common.
People live long enough to become grandparents even if they have untreated celiac disease so they pass their genes.
There are various forms of alcohol intolerance. If people had “instant alcoholism” gene, they had it easier to handle their liquor before invention of distillation. Also some kind of alcoholism was a norm in the history.
Glutenintolerance is not an allergy. It’s an autoimmune disease.
It is not supposed to happen. Allergies arent either.
The amount of years consuming this stuff doesnt have an effect on why and if mistakes happen in your body.
Lactose intolerance is an example of the things you are talking about. And this is because humans arent supposed to consume milk after a certain age. They naturally lose the capability to produce lactase. But in this case, thousands of years consuming it DID have the effect you are talking about. Many ppl nowadays do produce lactase even as adults.

Simply put; there’s nothing really to select against it in such a way that either would be considerably less likely to happen. Being allergic to alcohol or gluten wouldn’t ever have been a particularly devastating affliction other than in a society where food included them in huge (basically exclusively) amounts.
The fact that the “bread and beer” tribes didn’t take over the world means that those with alcohol or gluten intolerance simply weren’t at threat to being wiped out so the genes survive.
It’s basically the same reason as to why people who get wisdom teeth still exist; they aren’t usually lethal, so there’s not much for nature to select them out of the population and replace them with us mutants that have the non-wisdom teeth gene.

The environment hasn’t produced the conditions where one set of genes would be fitter than another in the context of consuming alcohol and gluten.
In an extreme case, let’s say the only viable food source was gluten bread – that is, that is the only food in the whole world that we can consume. Over time, those who can more easily digest gluten bread are more likely to live longer and reproduce, thus carrying their generic disposition to process gluten.
But in the real world, people can and will consume gluten bread. More importantly, they *also eat other foods*. You can survive without bread, and many cultures don’t eat bread as a staple. Thus, we’re not going to see a genetic shift to reduce intolerance to specific foods because they will live long and prosper by simply not consuming the foods they cannot eat.
