Eating fresh fruits and veggies is a great general health advice but unlikely to shift your gut microbiome meaningfully (unless you are eating some specific fruits or fruit skins in specific conditions).
And randomly eating healthy stuff is probably not going to shift your biome in a particular direction nor eliminate the cause of biome issues.
I eat healthy including a lot of whole fruit, nuts, dried fruits, dark green veggies and grass finished meats and there are still times I have my biome be a bit off.
“Unlikely”, “randomly”, and “probably” had me nervous about your contribution to this discussion.
I do appreciate the quantitative precision at the end of your last sentence.
