Lin et al. presented the largest cross-sectional study to date on the gut microbiome and kidney health. Their use of a vast sample size, discovery and validation approach, shotgun metagenomics, and integration with serum metabolomics represents a significant advance. In this commentary, we place these new findings into context with prior research and highlight the need for studies with a prospective design to identify true temporal relationships of the gut microbiome with kidney health.

Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of...
