Abstract

Malnutrition may manifest as either obesity or undernutrition. Accumulating evidence suggests that the gut microbiota plays an important role in the harvest, storage, and expenditure of energy obtained from the diet. The composition of the gut microbiota has been shown to differ between lean and obese humans and mice; however, the specific roles that individual gut microbes play in energy harvest remain uncertain. The gut microbiota may also influence the development of conditions characterized by chronic low‐level inflammation, such as obesity, through systemic exposure to bacterial lipopolysaccharide derived from the gut microbiota. In this review, the role of the gut microbiota in energy harvest and fat storage is explored, as well as differences in the microbiota in obesity and undernutrition.

  • The majority of carbohydrate-metabolizing microbes reside in the colon.

    “where the majority of carbohydrate-metabolizing microbes reside (Krajmalnik-Brown et al., 2012).”
  • If not for the colonic microbiota, indigestible carbohydrates and proteins would generally be eliminated via the stool without further absorption due to the limited digestive capability of the human large intestine.

    “If not for the colonic microbiota, these nutrients would generally be eliminated via the stool without further absorption due to the limited digestive capability of the human large intestine [142].”

  • In healthy adults, approximately 85% of carbohydrates, 65-95% of proteins, and nearly all fats are absorbed before entering the large intestine.

  • Even less is known about the gut microbiota in undernutrition compared to high-energy intake and obesity.

    “In contrast to high-energy intake and obesity, even less is known about the gut microbiota in undernutrition [142].”

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.
