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.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
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.
What the research says
1 studyEven 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.
