Immunity developed by environment?

Hi guys I'm doing a project on a real-life example I've experienced, but I REALLY need evidence for it, and I can't find much online. So please help. The idea is like this:

People born in relatively unhygienic environments develop a sort of 'resistance' to common diseases like common cold and asthma, food poisoning and other digestive problems. It's not 'immunity' since these ailments can still strike them, but it's like harder for these people to catch these diseases because they've been 'coexisting with the germs since birth'. Yeah, somehting like that. I know this for sure because I come from India and am currently in Singapore, so I can spot the differences. Also, my cousins in the US and Australia are less resilient to these diseases than my family back in India.

So any concrete evidence people? Please please please help me

    I'm not aware of any recent evidence or studies about this subject, but you might try using historical examples, probably the best documented would be related to the settlement of the Americas and the higher mortality rates amongst the native peoples who were unexposed to the diseases brought in by European settlement try this link to a paper by Wolfe dealing with mortality rates in the native peoples of Alaska,

    Hope that helps

    Evolution isn't purely the adaption to the ecosystem. it is likewise the evolution of animals right into a condition the place they have the terrific achievable possibility to stay to tell the story. it is organic decision; the animals that can't make it interior the international die, and people who stay on the longest get to mate extra, and pass on their features to the subsequent era. micro organism bobbing up immunity is evidence of evolution interior an identical way. micro organism is a existence sort and, as such, is going via evolution purely besides as different existence types will. via micro organism bobbing up immunity, we are able to make certain a classic occasion of a few thing adapting to the international and evolving via organic decision to furnish it the terrific achievable possibility to stay to tell the story. So I counter you; How ought to it not be an occasion of evolution?
