Abstract

Diets rich in animal source foods vs plant-based diets have different macronutrient composition, and they have been shown to have differential effects on the gut microbiome. In this study, we hypothesized that diets with very different nutrient composition are able to change gut microbiome composition and metabolites in a very short period. We compared a fast food (FF) diet (ie, burgers and fries) with a Mediterranean (Med) diet, which is rich in vegetables, whole grains, olive oil, nuts, and fish. Ten healthy subjects participated in a controlled crossover study in which they consumed a Med diet and FF diet in randomized order for 4 days each, with a 4-day washout between treatments. Fecal DNA was extracted and the 16S V4 region amplified using polymerase chain reaction followed by sequencing on an Illumina MiSeq. Plasma metabolites and bile acids were analyzed using liquid chromatography-mass spectrometry. Certain bile-tolerant microbial genera and species including Collinsella, Parabacteroides, and Bilophila wadsworthia significantly increased after the FF diet. Some fiber-fermenting bacteria, including Lachnospiraceae and Butyricicoccus, increased significantly after the Med diet and decreased after the FF diet. Bacterially produced metabolites indole-3-lactic acid and indole-3-propionic acid, which have been shown to confer beneficial effects on neuronal cells, increased after the Med diet and decreased after the FF diet. Interindividual variability in response to the treatments may be related to differences in background diet, for example as shown by differences in Bilophila response in relationship to the saturated fat content of the baseline diet. In conclusion, an animal fat-rich, low-fiber FF diet v. a high-fiber Med diet altered human gut microbiome composition and its metabolites after just 4 days.

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?

  • A small pilot crossover study in humans showed a detrimental impact on the gut microbiota and associated metabolites within 4 days of adopting a Western-style diet, with increases in bile-tolerant microbes, including Collinsella, Parabacteroides, and B. wadsworthia, as well as increases in TMAO and decreases in indole-3-lactic acid and indole-3-propionic acid.

    “More recently, a small pilot crossover study in humans showed a detrimental impact on the gut microbiota and associated metabolites within 4 d of adopting a Westernstyle diet, with increases in bile-tolerant microbes, including Collinsella, Parabacteroides, and B. wadsworthia, as well as increases in TMAO and decreases in the metabolites indole-3-lactic acid and indole-3-propionic acid (205).”
  • In a recent pilot study, consumption of a Mediterranean and fast-food diet differentially affected tryptophan metabolites in humans.

    “A direct effect of diet on tryptophan metabolites in humans was demonstrated in a recent pilot study, in which consumption of a Mediterranean and fastfood diet differentially affected tryptophan metabolites ( 205).”

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.
