The Claim
Runners of both sexes with a daily dietary fibre intake 3 g/day lower than average have an increased risk of running-related injury.
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.
Runners who consume 3 grams less dietary fibre per day than average have a higher rate of running-related injuries.
See the scientific wording
Runners of both sexes with lower daily dietary fibre intake (by an average of 3 g/day) have an increased risk of running-related injury, based on moderate-certainty evidence from a meta-analysis of prospective cohort studies.
When people eat less fibre, the good bacteria in their gut make fewer chemicals that calm inflammation. This causes more inflammation throughout the body, which slows down the healing of muscles and tendons after running, making injuries more likely.
What the research says
1 studyRunners who eat less fibre each day are more likely to get injured while running, according to a review of many studies. This doesn’t mean fibre stops injuries, but it’s a pattern that shows up again and again.
