The Claim

Higher intake of ultra-processed foods is associated with reduced abundance of Agathobacter in elite male basketball players, even when dietary fiber intake is adequate at 27.7 g/day.

In plain English

Elite male basketball players who eat more ultra-processed foods have lower levels of Agathobacter bacteria in their gut, even when they consume the recommended amount of dietary fiber.

See the scientific wording

In elite male basketball players, higher ultra-processed food intake is associated with lower abundance of Agathobacter, a genus linked to dietary fiber metabolism, despite adequate fiber intake (27.7 g/day), suggesting that ultra-processed foods may disrupt gut microbiota independently of fiber consumption.

Why this might work

Eating a lot of ultra-processed foods introduces chemicals and refined ingredients into the gut that change the environment where good bacteria live. Even when fiber is eaten in enough amounts, these chemicals make it harder for Agathobacter to survive and grow, so their numbers drop. This happens because the gut bacteria that break down fiber need a stable environment, and the additives interfere with that stability.

  1. Study: Consumption of ultra-processed foods does not affect neuromuscular and cardiovascular fitness but alters gut microbiota in elite basketball players

    Even when elite basketball players eat enough fiber, eating lots of ultra-processed foods still lowers a helpful gut bacterium called Agathobacter, which means these foods might hurt gut health in ways that aren't just about fiber.
