METABOLISM #10: PERSONALIZED METABOLOMICS- Metabolomics measures small chemicals which all the organs of your body and your gut bacteria have created from the foods you eat. Whatever you don’t absorb , is broken down by your gut bacteria and re-enters your blood stream to finally be excreted from your body in the urine. Using mass spectrometry , scientists can identify all of these small chemicals (15 to 1500 molecular weight) and this becomes a metabolic fingerprint. Shown on the slide is the result of a study of 3500 twins in the UK with the same human genes but different diets , gut bacteria , and excreted metabolites. The green areas on the disk of chemicals are areas where twins had similar chemicals while the red areas are where they differed. The bar graphs below that show how the pat
