The Claim

In patients with Hashimoto thyroiditis, higher consumption of animal-derived protein is associated with lower abundance of Bacteroides in the gut microbiota.

In plain English

In people with Hashimoto thyroiditis, eating more animal-derived protein is linked to lower levels of Bacteroides bacteria in the gut.

See the scientific wording

In patients with Hashimoto thyroiditis, higher consumption of animal-derived protein is associated with lower abundance of Bacteroides in the gut microbiota, suggesting diet may modulate microbial composition in this population.

Why this might work

When more animal protein is eaten, the gut gets flooded with amino acids, which changes what bacteria can thrive. Bacteroides bacteria, which normally feed on plant fibers, struggle to survive in this environment, so their numbers drop. This shift in bacteria also changes the chemicals they produce, which can affect the gut lining and immune activity.

  1. Study: Detection of Alterations in the Gut Microbiota and Intestinal Permeability in Patients With Hashimoto Thyroiditis

    This study found that people with Hashimoto’s who eat more meat and other animal proteins tend to have less of a certain gut bacteria called Bacteroides compared to those who eat less animal protein. So yes, what you eat seems to change your gut bacteria in this condition.
