The Claim

Daily consumption of pasteurized sauerkraut for four weeks is associated with a significant reduction in fasting blood glucose and fructosamine levels in healthy adults under 50 years of age.

In plain English

In healthy adults under 50, eating pasteurized sauerkraut every day for four weeks is linked to lower fasting blood glucose and fructosamine levels.

See the scientific wording

In healthy adults under 50 years of age, daily consumption of pasteurized sauerkraut for four weeks is associated with a significant reduction in fasting blood glucose and fructosamine levels, suggesting greater metabolic responsiveness to sauerkraut in younger individuals.

Why this might work

Compounds made during fermentation of cabbage block an enzyme that raises blood pressure and trigger gut bacteria to produce chemicals that calm inflammation. This reduces stress on the body’s metabolism, allowing cells to take up sugar from the blood more efficiently, which lowers blood sugar levels.

  1. Study: Fermented foods and inflammation: a crossover intervention trial with fresh and pasteurized sauerkraut.

    The study found that younger adults under 50 who ate pasteurized sauerkraut every day for a month had better blood sugar control, just like the claim says. Even though the sauerkraut was cooked (killing the good bacteria), it still helped.
