Do Fermented Foods Actually Reduce Inflammation? A Randomised Trial Just Gave Us an Honest Answer. Fermented foods have had a good few years on social media. Sauerkraut, kimchi, kefir: all positioned as gut-healing, inflammation-reducing, metabolically protective. Patients ask about them regularly. Most clinicians have not had solid trial data to point to. A randomised crossover trial published in the European Journal of Clinical Nutrition this month gives us that data. The results are more nuanced than the wellness industry would like. 87 healthy adults consumed 100g of sauerkraut daily for four weeks, alternating between fresh sauerkraut containing live bacteria and pasteurised sauerkraut with no viable bacteria. Each intervention phase was separated by a four-week washout. Blood markers for inflammation, gut permeability, and glycaemic control were measured before and after each phase. Blood pressure, modest but real reduction. Both fresh and pasteurised sauerkraut produced a statistically significant drop in systolic blood pressure of approximately 1.5 to 2.5 mmHg. The effect was more pronounced in participants under 5
