The Claim

Inter-individual variation in sulforaphane metabolite excretion after consumption of broccoli sprouts is strongly associated with gut microbiome composition, with specific bacterial taxa including Bifidobacterium, Dorea longicatena, and Ruminococcus torques correlating with higher excretion, while Alistipes and Blautia correlate with lower excretion, explaining 81% of the variability in metabolite levels among healthy adults.

In plain English

The amount of sulforaphane metabolites excreted by healthy adults after eating broccoli sprouts varies between individuals, and this variation is linked to the types of bacteria present in their gut, with certain bacteria associated with higher or lower excretion levels.

Why this might work

When someone eats broccoli sprouts, gut bacteria break down a compound called glucoraphanin. Some bacteria turn it into sulforaphane, which the body absorbs and turns into waste products that show up in urine. Other bacteria turn it into a different compound that the body cannot use and clears slowly. The mix of bacteria in a person’s gut decides which path happens, and that determines how much useful waste they excrete.

  1. Study: Sulforaphane and Sulforaphane-Nitrile Metabolism in Humans Following Broccoli Sprout Consumption: Inter-individual Variation, Association with Gut Microbiome Composition, and Differential Bioactivity

    People who eat broccoli sprouts and excrete more of the healthy compounds tend to have different gut bacteria than those who excrete less — and this study found that specific good bacteria like Bifidobacterium are linked to higher levels, while others like Alistipes are linked to lower levels.
