Fermented mageu changed gut diversity and a blood marker in breastfeeding mothers
A randomized trial examined a fermented grain food during lactation, finding changes in microbial diversity and ferritin without establishing benefits for maternal or infant health.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Among breastfeeding mothers in South Africa, live-culture mageu increased gut microbial diversity during the consumption period. Users also had lower circulating ferritin than non-users. These are changes in microbiota and a blood marker; the abstract does not establish improved maternal health or benefits for infants.
The abstract provides no sample size, effect sizes or uncertainty intervals. It reports no infant outcomes, and the health meaning of the ferritin decrease is not established.
What researchers found
Circulating ferritin
At week 10, live-culture mageu users had lower circulating ferritin than mothers consuming no mageu; no effect size or uncertainty interval was provided.
What researchers compared
Mothers were assigned to different mageu conditions during lactation. Researchers collected dietary and clinical information, examined stool microbes, and measured nutritional and inflammatory biomarkers to explore how the food related to these outcomes.
What the changes mean
Gut microbial diversity increased during live-culture mageu consumption, and plant protein intake was higher among mageu users. The abstract does not establish whether these changes translated into better health or whether live-culture mageu outperformed pasteurized mageu.
