The Claim
Both fresh and pasteurized sauerkraut produce equivalent modest reductions in systolic blood pressure, indicating that live bacteria are not required for this effect and that non-microbial components such as organic acids, peptides, or phenolic compounds may mediate the reduction.
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.
Eating fresh or pasteurized sauerkraut results in the same modest decrease in systolic blood pressure, meaning the live bacteria in sauerkraut are not responsible for this effect; other compounds like organic acids, peptides, or phenolic substances are likely responsible.
See the scientific wording
Live bacteria in sauerkraut are not required to achieve a modest reduction in systolic blood pressure, as both fresh and pasteurized sauerkraut produced equivalent effects, suggesting non-microbial components such as organic acids, peptides, or phenolic compounds may mediate this benefit.
Chemicals made when cabbage ferments block a key enzyme that tightens blood vessels, causing the vessels to relax and blood pressure to drop.
What the research says
1 studySauerkraut lowered blood pressure whether it had live bacteria or not, so the good effect probably comes from chemicals made during fermentation, not the bacteria themselves.
