The Claim

TrnL gene sequencing of fecal samples detects 34% more plant genera than self-reported food diaries in adults with Crohn’s disease.

In plain English

In adults with Crohn’s disease, analyzing DNA from fecal samples identifies 34% more types of plants consumed than asking people to record their food intake.

See the scientific wording

TrnL gene sequencing of fecal samples detects 34% more plant genera than self-reported food diaries in adults with Crohn’s disease, demonstrating its potential as a more objective tool for monitoring dietary adherence in clinical research.

Why this might work

When people eat plants, the DNA from those plants passes through the digestive system without being fully broken down. This DNA ends up in poop, where it can be picked up by special tests that look for plant DNA signatures. People trying to remember what they ate often miss many plants, but the DNA in their poop shows exactly which plants were eaten, because the DNA doesn't change even if the person forgets to report it.

  1. Study: Modulating the gut microbiota in Crohn’s disease: a pilot study on the impact of a plant-based diet with DNA-based monitoring

    People with Crohn’s disease tried to write down what plants they ate, but their lists missed many. When scientists checked their poop using DNA tests, they found 55 different plant types—14 more than what people remembered. So DNA testing gives a more accurate picture of what people really ate.
