Fibermaxxing: the gut trend with evidence behind it

Most food trends outrun their research. This one arrived late to a body of work that was already there.

The first signs were administrative. A supplier note here, a substitution there — the kind of paperwork that never reaches a headline until the day it does.

What follows was reconstructed from public filings, two regulators' correspondence and eleven conversations with people who were in the room. Names are used where permission was given.

How it started

The pattern held across every place we checked, which is usually a sign that the cause is structural rather than local. Where it broke down, it broke down for reasons that were specific, documented and — in retrospect — predictable.

“By the time it was obvious from the outside, it had been obvious from the inside for a month.”

What changed on the ground

People adapted the way people always do: informally, quickly, and without a budget line. Staff rewrote their own protocols, called colleagues in other districts, and kept a shared spreadsheet that outperformed the official dashboard for six weeks.

That improvisation worked, which is both the good news and the problem. A system that survives on goodwill is not resilient; it is borrowing against people who cannot keep lending.

What happens next

Two reviews are open and one timeline has been published. The measures under discussion are unremarkable — buffers, second sources, mandatory notice periods — which is usually a sign that the fix is known and the will is the variable.
