The Claim
Higher intake of ultra-processed foods is associated with increased salivary IL-1β levels, which are positively correlated with abundance of Phocaeicola and negatively correlated with abundance of Faecalibacterium.
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.
People who eat more ultra-processed foods have higher levels of IL-1β in their saliva, and these levels are linked to higher amounts of Phocaeicola bacteria and lower amounts of Faecalibacterium bacteria.
See the scientific wording
Higher intake of ultra-processed foods is associated with increased salivary IL-1β, which is positively correlated with Phocaeicola and negatively correlated with Faecalibacterium, suggesting a potential microbial-inflammatory pathway.
Eating lots of ultra-processed foods changes the types of bacteria in the mouth and gut, causing harmful bacteria to increase and helpful bacteria to decrease. These harmful bacteria release substances that activate immune cells in the mouth, which then produce a protein called IL-1β.
What the research says
1 studyPeople who ate more ultra-processed foods had more inflammation in their saliva and more of one type of gut bacteria (Phocaeicola) while having less of another helpful gut bacteria (Faecalibacterium). This matches what the claim says.
