The Claim

Daily consumption of 100 grams of sauerkraut for four weeks has no appreciable effect on systemic health in healthy adults, as indicated by the absence of significant changes in inflammatory and metabolic biomarkers.

Source: Fermented foods and inflammation: a crossover intervention trial with fresh and pasteurized sauerkraut.

Description
1 study reviewed
In plain English

Eating 100 grams of sauerkraut every day for four weeks does not change measurable markers of inflammation or metabolism in healthy adults.

See the scientific wording

Daily consumption of 100 grams of sauerkraut for four weeks does not produce appreciable systemic health benefits in healthy adults, as most inflammatory and metabolic biomarkers showed no significant change despite minor subgroup effects.

Why this might work

Eating sauerkraut releases small protein fragments that block a blood pressure-raising enzyme, causing blood vessels to relax and lowering blood pressure slightly.
