There have been reports of YouTubers I watch getting sick after eating food in third world countries. However, these countries are also home to a large number of people who do not get sick from eating the same food. I think this suggests that the locals may have developed stronger immune systems to the bacteria and viruses that are present in the food. What do you think?

Not necessarily, it is likely that a tourist is just not used to these specific pathogens. While the people living there are used to them. So their immune system isn’t better per se just more adapted to the environment.

Study finds gut microbes adapt quickly to changes in food preparation

Scientists have recently discovered that different diets — say, high-fat versus low-fat, or plant-based versus animal-based — can rapidly and reproducibly alter the composition and activity of the gut microbiome, where differences in the composition and activity can affect everything from metabolism to immunity to behavior.
