Abstract

There is growing awareness that the profound changes in the environment (eg, in diet and other lifestyle conditions) that began with the introduction of agriculture and animal husbandry approximately 10000 y ago occurred too recently on an evolutionary time scale for the human genome to adjust. In conjunction with this discordance between our ancient, genetically determined biology and the nutritional, cultural, and activity patterns of contemporary Western populations, many of the so-called diseases of civilization have emerged. In particular, food staples and food-processing procedures introduced during the Neolithic and Industrial Periods have fundamentally altered 7 crucial nutritional characteristics of ancestral hominin diets: 1) glycemic load, 2) fatty acid composition, 3) macronutrient composition, 4) micronutrient density, 5) acid-base balance, 6) sodium-potassium ratio, and 7) fiber content. The evolutionary collision of our ancient genome with the nutritional qualities of recently introduced foods may underlie many of the chronic diseases of Western civilization.

  • Metabolic syndrome increases the risk for Type 2 diabetes, cardiovascular disease, and Alzheimer's disease.

    “Metabolic syndrome increases the risk for Type 2 diabetes and cardiovascular disease, and AD (Kivipelto et al., 2001; Luchsinger et al., 2004; Cordain et al., 2005; Whitmer et al., 2008).”

    The Glycemic load and Glycemic index sections link metabolic syndrome and insulin resistance with coronary heart disease and type 2 diabetes. The paper does not address Alzheimer’s disease in the passages found, so it does not support that part of the claim. Page numbers were not available in our copy. (LLM, conf=0.86)

  • The rationale for the hypothesis that diet influences oral microbiota relies on historical observation of the Neolithic and Industrial revolutions, which altered macronutrient proportions, glycemic load, fatty acid composition, sodium and potassium levels, micronutrient levels, dietary pH, and fiber content.

    “The rationale for this hypothesis relies on historical observation of two key periods in human history: the Neolithic and Industrial revolutions. These periods represented two critical junctures in our history with repercussions beyond economic, cultural, and social matters. Indeed, the foods and processing techniques that arose in these two historical periods significantly altered the central”
  • The change to dominance of caries-associated bacteria is most likely associated with the onset of the Industrial Revolution.

    “This change is most likely associated with the onset of the Industrial Revolution which began some 200 years ago and represents the largest change in food production and processing technology since the shift to farming9.”
  • The Industrial Revolution saw the production of refined grain and concentrated sugar, generating mono- and disaccharides that are the main substrates for microbial fermentation that lowers plaque pH and causes enamel demineralization.

    “The Industrial Revolution saw the production of refined grain and concentrated sugar from processed sugar beet and cane9, generating mono- and disaccharides, which are the main substrates for microbial fermentation that lowers plaque pH and cause enamel demineralization26.”
  • Food-processing technologies were broadly similar during the Neolithic through Medieval times.

    “in parallel with the broad similarity of food-processing technologies during these times9.”

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.
