The Claim
In healthy adults aged 51±12 years with high education levels, consuming 6.3 servings of fermented foods daily for 10 weeks increases gut microbiota diversity and reduces circulating levels of IL-6, IL-10, and IL-12b.
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.
In healthy adults aged 51±12 years with high education levels, consuming 6.3 servings of fermented foods daily for 10 weeks increases gut microbiota diversity and reduces circulating levels of IL-6, IL-10, and IL-12b.
See the scientific wording
In healthy adults aged 51±12 years with high education levels, consuming 6.3 servings of fermented foods daily for 10 weeks increases gut microbiota diversity and reduces circulating levels of multiple inflammatory cytokines, including IL-6, IL-10, and IL-12b, suggesting fermented foods may dampen systemic inflammation in industrialized populations.
Eating fermented foods introduces microbes and their byproducts into the gut, which change the environment so that more types of good bacteria grow. These bacteria produce chemicals that signal the immune system to become less active, leading to lower levels of inflammatory proteins in the blood.
What the research says
1 studyStudy: Gut-microbiota-targeted diets modulate human immune status
Eating about six servings a day of yogurt, kefir, or kimchi for 10 weeks made people’s gut bacteria more diverse and lowered their blood levels of inflammation markers — exactly what the claim says.
