Abstract

We review evidence that suggests a role for excessive consumption of energy-dense foods, particularly fructose, and consequent obesity and insulin resistance (metabolic syndrome) in the recent increase in prevalence of autism spectrum disorders (ASD). Maternal insulin resistance, obesity, and diabetes may predispose offspring to ASD by mechanisms involving chronic activation of anabolic cellular pathways and a lack of metabolic switching to ketosis resulting in a deficit in GABAergic signaling and neuronal network hyperexcitability. Metabolic reprogramming by epigenetic DNA and chromatin modifications may contribute to alterations in gene expression that result in ASD. These mechanistic insights suggest that interventions that improve metabolic health such as intermittent fasting and exercise may ameliorate developmental neuronal network abnormalities and consequent behavioral manifestations in ASD.

  • Maternal metabolic disorders including diabetes and obesity can pose another threat to the unborn child as placental dysfunctioning alters the prenatal exposure to nutrients and toxins.

    “Maternal metabolic disorders including diabetes and obesity can pose another threat to the unborn child as placental dysfunctioning alters the prenatal exposure to nutrients and toxins [312–314].”

    From Development of prefrontal cortex (2022) · cites this paper as [314]

    The “Maternal Metabolic Syndrome and ASD” section (page not provided) says that a fetus of a mother with metabolic syndrome is exposed to elevated glucose, insulin, and pro-inflammatory cytokines, and it links maternal obesity and diabetes to risks for offspring. It does not say that placental dysfunction alters exposure to nutrients and toxins; its discussion of prenatal toxicants does not connect them to maternal metabolic disorders or placental 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.
