As you suggest the genes/piano is sort of the hand you are dealt (you have the gene for certain disease or not), but the microbiome is what will typically unlock those diseases or not given the gene set.
The way I used to describe it was that your genes are like the blueprints for a house and what you eat is like local building materials. The blueprints may specify 2 bedrooms, one bathroom, but exactly how that will look will depend a lot on the vernacular architecture. Is it adobe brick because you live in the American Southwest? Is it made of blocks of ice because you are an Inuit? Etc.
So, different building materials have different strengths and weaknesses. This will significantly impact things like ceiling height and room size because what shapes the material supports will vary, depending on the material.
I'm sorry some people are reflexively downvoting. I hate it that so many people who imagine themselves to be scientific are so incredibly dismissive of stuff like this.
