Focus of Study: 1- Effect of Tea Consumption on Gut Microbiota, Focus of Study: 2- Effect of Tea Consumption on Body-iron Status
Can the Reduction of Iron Availability Caused by Tea Consumption Change the Gut Microbiota Composition and Disrupt Host Body-iron Status
Iron is an essential micronutrient for nearly all living organisms, including microbes. The adult human body contains approximately 3-5 g of iron (45-55 mg/kg of body weight in adult women and men, respectively).
