The Claim
In Korean adults, fermented foods contribute a substantial portion of dietary sodium, with kimchi and jang-based products being the primary sources, and sodium intake from these foods increases with age despite a decline in overall fermented food consumption.
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, most dietary sodium comes from fermented foods like kimchi and jang, and older adults consume more sodium from these foods than younger adults, even though they eat less of them overall.
See the scientific wording
In Korean adults, fermented foods contribute a substantial portion of dietary sodium, with kimchi and jang-based products being the primary sources, and sodium from these foods increases with age despite lower overall fermented food intake.
As people get older, their kidneys remove less salt from the body, so salt builds up in tissues. This extra salt activates immune cells, which release chemicals that cause inflammation. Even though older people eat less fermented food like kimchi, the salt in those foods still triggers this inflammation because their bodies are more sensitive to salt. The inflammation signals the liver to make more CRP, a marker of body-wide inflammation.
What the research says
1 studyOlder Koreans eat less kimchi and soy paste than younger people, but the salt in those foods still affects their health more because their bodies react more strongly to sodium as they age.
