Gut Microbiome, Metabolome, and SSBP

The goal of this interventional study is to learn if elevated Na+ alters the gut microbiota and is associated with altered metabolism, inflammation and salt sensitivity of blood pressure (SSBP). The main questions it aims to answer are: * SSBP correlates with Na+-induced changes in gut microbiome composition * Na+-induced changes in the gut microbiome and SSBP are associated with altered metabolism and with immune cell activation * Microbiota from humans with SSBP induce inflammation and hypertension in germ-free mice. Researchers will quantify SSBP from 24-hour ambulatory BP monitoring in a randomized crossover design, using standardized one week low- and high-salt diets. Participants will: * Take high- and low-salt diet each for one-week * Complete three study visits, with each visit being 1 week apart * Complete a 72-hour dietary log
