The Claim
Daily consumption of 100 grams of fresh or pasteurized sauerkraut for four weeks reduces systolic blood pressure by 1.5 to 2.5 mmHg on average in healthy adults aged 21–69, and non-viable microbial components or other bioactive compounds in sauerkraut contribute to blood pressure regulation independent of live bacteria.
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 100 grams of fresh or pasteurized sauerkraut every day for four weeks lowers systolic blood pressure by 1.5 to 2.5 mmHg on average in healthy adults aged 21–69. This effect is due to non-live components in sauerkraut, not live bacteria.
See the scientific wording
Daily consumption of 100 grams of fresh or pasteurized sauerkraut for four weeks reduces systolic blood pressure by 1.5 to 2.5 mmHg on average in healthy adults aged 21–69, suggesting that non-viable microbial components or other bioactive compounds in sauerkraut may contribute to blood pressure regulation independent of live bacteria.
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.
What the research says
1 studyEating a small bowl of sauerkraut every day for a month lowered blood pressure a little bit — whether it was fresh or cooked (pasteurized). That means it’s not the live bacteria causing the drop, but something else in the sauerkraut.
