The Claim
In elite male basketball players, a higher consumption of ultra-processed foods (averaging 49% of daily energy intake) is associated with significantly lower abundance of the gut bacterial family Veillonellaceae and genus Agathobacter, independent of neuromuscular and cardiovascular fitness levels.
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 specific gut bacteria linked to short-chain fatty acid production, even when their athletic fitness is unchanged.
See the scientific wording
In elite male basketball players, higher consumption of ultra-processed foods (averaging 49% of daily energy intake) is associated with significantly lower abundance of the gut bacterial family Veillonellaceae and genus Agathobacter, which are linked to short-chain fatty acid production, despite no measurable differences in neuromuscular or cardiovascular fitness, suggesting a specific impact on gut microbiota composition independent of athletic performance metrics.
When people eat a lot of ultra-processed foods, they consume less fiber. This starves certain gut bacteria that need fiber to survive and produce useful compounds. As a result, these bacteria decline, and the body makes fewer of those compounds, which are important for gut health and metabolism.
What the research says
1 studyEven though these basketball players stayed just as strong and fit, those who ate more junk food had less of two helpful gut bacteria that make good compounds for the body. So, junk food affects their gut bugs, even if it doesn’t change their athletic performance.
