When mice with human gut bacteria were given sugar (fructose) and a food preservative (potassium sorbate) together, their gut bacteria changed in a unique way—especially a type called Akkermansia that jumped four times higher—and this change seemed to go along with worse liver damage.

Synergistic Effects of Fructose and Food Preservatives on Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD): From Gut Microbiome Alterations to Hepatic Gene Expression

Cohort Study

Animal

2024 Oct 30

The study gave mice a mix of fructose and potassium sorbate (a food preservative) and found that it changed their gut bacteria in ways linked to liver damage — just like the claim said.

Similar Assertions

When mice with human gut bacteria were given a drink with 10% sugar (fructose) and a common food preservative (potassium sorbate) for 11 weeks, their livers got more fatty, inflamed, and scarred than expected—suggesting the two together are worse for the liver than either one alone.

When mice with human gut microbes were fed a mix of fructose and potassium sorbate, the fungi in their guts became less diverse, but the bacteria stayed the same—suggesting this food combo specifically hurts the fungal community.
