The Claim
Fermented food intake as a percentage of daily energy decreases with age in Korean adults, from 10.2% in individuals aged 20–39 to 7.2% in those aged 65 and older, with a shift in consumption patterns from dairy and grains to high-sodium fermented vegetables and soy products.
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 Korean adults, the proportion of daily energy from fermented foods drops from 10.2% in people aged 20–39 to 7.2% in those aged 65 and older, and the types of fermented foods consumed shift from dairy and grains to high-sodium vegetables and soy products.
See the scientific wording
Fermented food intake decreases significantly with age in Korean adults, from 10.2% of daily energy in those aged 20–39 to 7.2% in those aged 65 and older, reflecting a shift from dairy and grains to high-sodium fermented vegetables and soy products.
As people get older, they eat less fermented food, so fewer beneficial bacterial byproducts reach the gut. This weakens the gut barrier and reduces signals that calm inflammation. At the same time, older adults eat more salty fermented foods, and the extra sodium builds up in tissues, triggering immune cells to release inflammatory chemicals. These chemicals signal the liver to produce more inflammation markers, and without enough fermented food to counteract it, inflammation stays high.
What the research says
1 studyThe study found that older Korean adults eat less fermented food overall than younger adults, and what they do eat tends to be salty items like kimchi and soy paste — just like the claim says.
