How to stop nail polish from chipping?

Hi! I make a lot of bread, and that means that I wash my hands a lot. I also have to make sure that my nails are well maintained, and I was wondering if there was anything I could do to to ensure that my nail polish doesn't chip if I apply some while taking care of my hands and nails. I own quite a bit of nail polish, and other nail painting related stuff, but I've never gotten away with them being fully painted for long, because they will always chip. Because I work with my bare hands I want to make sure both that my hands are sanitary and won't cause chips of polish to get into my doughs.

TL;DR: I want to do my nails so I can ensure they are always clean and trimmed for baking bread and what not, but I'm unsure of how to ensure the polish will not get into what I make through chipping, any tips?
