Short-term fiber-rich vs fiber-poor diet switch, Germany

Synchronized response of CD4+ T cells to short-term dietary changes leads to windows of mucosal and systemic immune depression

30 fecal samples from healthy adult volunteers in Germany, collected after 5-day fiber-rich and fiber-poor diet phases; shotgun metagenomics intervention study of short-term dietary switching. machine-written summary

Sampling design and relatedness

longitudinal — not resolved

6 of 6 people sampled more than once (12 samples; median 2, up to 2 per person). Schedule stated by the source: “Stool collected at end of fiber-rich diet phase (day 5) and end of fiber-poor diet phase (day 10)” (time origin: intervention start); stated follow-up 10 d.

Archive description

Healthy volunteers were offered one defined fiber-rich diet (FRD) and one defined fiber-poor diet (FPD), both consumed for 5 consecutive days. Stool samples were collected at the end of each dietary switch (i.e. end of fiber-rich, FRD and fiber-poor diet, FPD phases). Shotgun metagenomics and fecal microbiota transfer (FMT) into germ-free (GF) mice were performed.
