Dietary Modification of the Microbiome Affects Risk for Cardiovascular Disease

Mendelsohn, Andrew R., Larrick, James W.·2013·Rejuvenation Research

Abstract

The incidence of cardiovascular disease (CVD) increases with age and is associated with some syndromes that exhibit aspects of premature aging, such as progeria. Various factors are thought to contribute to the progression of CVD, including hypertension, hypercholesterolemia, diets rich in saturated and trans fats, etc. Recent reports have uncovered an important connection between diet, the microbiome, and CVD. Dietary carnitine (present predominately in red meat) and lecithin (phosphatidyl choline) are shown to be metabolized by gut microbes to trimethylamine (TMA), which in turn is metabolized by liver flavin monoxygenases (especially FMO3 and FMO1) to form trimethylamine-N-oxide (TMAO). High levels of TMAO in the blood strongly correlate with CVD and associated acute clinical events. Plasma TMAO levels may be an important clinical biomarker for CVD. The data suggest that that presence of specific as yet unidentified microorganisms in the gut linked to diet are required for high TMAO levels and TMAO-mediated CVD progression. Development of novel therapeutic approaches to manipulate gut flora may help treat CVD.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Reducing carnitine or choline levels in the diet is not a possibility for treating TMAO-related diseases because they are important nutrients and low levels can lead to organ dysfunction.

    “Instead of changing the gut microbiota, the option of reducing carnitine or choline levels in the diet would not be a possibility because they are important nutrients and low levels of them can lead to organ dysfunction.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
