Abstract

Omnivorous animals, including mice and humans, tend to prefer energy-dense nutrients rich in fat over plant-based diets, especially for short periods of time, but the health consequences of this short-term consumption of energy-dense nutrients are unclear. Here, we show that short-term reiterative switching to ‘feast diets’, mimicking our social eating behavior, breaches the potential buffering effect of the intestinal microbiota and reorganizes the immunological architecture of mucosa-associated lymphoid tissues. The first dietary switch was sufficient to induce transient mucosal immune depression and suppress systemic immunity, leading to higher susceptibility to Salmonella enterica serovar Typhimurium and Listeria monocytogenes infections. The ability to respond to antigenic challenges with a model antigen was also impaired. These observations could be explained by a reduction of CD4 + T cell metabolic fitness and cytokine production due to impaired mTOR activity in response to reduced microbial provision of fiber metabolites. Reintroducing dietary fiber rewired T cell metabolism and restored mucosal and systemic CD4 + T cell functions and immunity. Finally, dietary intervention with human volunteers confirmed the effect of short-term dietary switches on human CD4 + T cell functionality. Therefore, short-term nutritional changes cause a transient depression of mucosal and systemic immunity, creating a window of opportunity for pathogenic infection.

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

  • The effects of the short-term dietary switch are associated with a rapid reduction of SCFAs, impaired mTOR activity, and mitochondrial function of CD4+ T cells.

    “These effects are associated with a rapid reduction of SCFAs, impaired mTOR activity, and mitochondrial function of CD4+ T cells.709”
  • A short-term dietary switch from a fiber-rich diet to a low-fiber feast diet induces a transient depression of mucosal and systemic immunity by impairing the metabolic fitness of both mucosal and peripheral CD4+ T cells.

    “A recent study found that a short-term dietary switch from a fiber-rich diet to a low-fiber feast diet induced a transient depression of mucosal and systemic immunity by impairing the metabolic fitness of both mucosal and peripheral CD4+ T cells.”

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.
