The Claim
The reduction in systolic blood pressure observed after sauerkraut consumption is mediated by non-probiotic components such as organic acids, peptides, or fiber, as both fresh and pasteurized sauerkraut produce similar reductions in systolic blood pressure.
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.
Consuming either fresh or pasteurized sauerkraut lowers systolic blood pressure by the same amount, indicating that the effect is caused by non-living components like organic acids, peptides, or fiber, not by live bacteria.
See the scientific wording
The reduction in systolic blood pressure from sauerkraut consumption is not dependent on live bacteria, as both fresh and pasteurized sauerkraut produced similar effects, suggesting non-probiotic components such as organic acids, peptides, or fiber may mediate this benefit.
Fermented cabbage releases peptides that block an enzyme that normally tightens blood vessels. When this enzyme is blocked, blood vessels relax, and blood pressure drops. This happens whether or not live bacteria are present, because the peptides survive pasteurization.
What the research says
1 studyWhether the sauerkraut had live bacteria or not, it lowered blood pressure by the same small amount—so the good effect must come from other parts of the food, not the bacteria.
