The Claim
Daily consumption of 100 grams of fresh or pasteurized sauerkraut for four weeks is associated with a small but statistically significant reduction in systolic blood pressure by 1.5 to 2.5 mmHg in healthy adults aged 21–69, and non-probiotic components of sauerkraut may contribute to blood pressure modulation 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 in healthy adults aged 21–69, and this effect is not due to live bacteria.
See the scientific wording
Daily consumption of 100 grams of fresh or pasteurized sauerkraut for four weeks is associated with a small but statistically significant reduction in systolic blood pressure by 1.5 to 2.5 mmHg in healthy adults aged 21–69, suggesting that non-probiotic components of sauerkraut may contribute to blood pressure modulation independent of live bacteria.
Cabbage fermented into sauerkraut produces small protein fragments that block a body system that tightens blood vessels. This blockage causes blood vessels to relax, which lowers the pressure inside them.
What the research says
1 studyEating a small bowl of sauerkraut every day for a month slightly lowered blood pressure in healthy adults, whether the sauerkraut had live bacteria or not — so something else in the sauerkraut, not the bacteria, must be helping.
