I find there is nothing you can do but just travel more. Eat more street food, bite your nails andwash your teeth with the tap water etc. Get down and dirty.
There is no such thing as a free immune system. You need plenty of experience of having miserable tummy bugs and travel sickness to get strong.
You can't live in a sterile environment when travelling. You have to face it all eventually.
In my early travel days, I used to get sick at least once a trip. And badly. Now I can pretty much eat anything from anywhere. And never get ill.
Having a very strong gut microbiome is important too. Eat plenty of fruit and veg. Lots of fermented foods. That is key to a good digestive immune system.
And of course. Always pack some immodium and a few courses of ciprofloxicin incase you do get a really bad one that you can't shake off.
