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.

In plain English

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.

Why this might work

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.

  1. Study: 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.
