High alpha diversity in the gut microbiome is dependent on linoleic acid and an evolutionarily consistent diet rich in nose-to-tail nutrients, not plant fiber.

“it's not about plant fiber for alpha diversity it's not about plant fiber for healthy gut i actually believe that it's mostly about linoleic acid and eating an evolutionarily consistent diet that is free for as many plant toxins as possible and full as as many nose to tail nutrients as you can get”
