Promoting Health and Longevity through Diet: From Model Organisms to Humans

Abstract

Reduced food intake, avoiding malnutrition, can ameliorate aging and aging-associated diseases in invertebrate model organisms, rodents, primates, and humans. Recent findings indicate that meal timing is crucial, with both intermittent fasting and adjusted diurnal rhythm of feeding improving health and function, in the absence of changes in overall intake. Lowered intake of particular nutrients rather than of overall calories is also key, with protein and specific amino acids playing prominent roles. Nutritional modulation of the microbiome can also be important, and there are long-term, including inter-generational, effects of diet. The metabolic, molecular, and cellular mechanisms that mediate both improvement in health during aging to diet and genetic variation in the response to diet are being identified. These new findings are opening the way to specific dietary and pharmacological interventions to recapture the full potential benefits of dietary restriction, which humans can find difficult to maintain voluntarily.

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

  • Long-lived animals including naked mole-rats, calorie-restricted/intermittent-fasting rodents, and long-lived daf-2 mutant worms have decreased oxidative damage and greater resistance to oxidative stress.

    “Accordingly, long-lived animals, including the naked mole-rat, rodents maintained on calorie restricted (CR) and intermittent fasting (IF) diets, and long-lived daf-2 mutant worms exhibit decreased levels of oxidative damage and are more resistant to oxidative stress (Fontana and Partridge, 2015; Guarente and Kenyon, 2000; Pérez et al., 2009).”

  • Exercise and dietary changes including caloric restriction and intermittent fasting can slow and even reverse aging progression.

    “Exercise and dietary changes, including caloric restriction and intermittent fasting, can slow and even reverse the progression of aging (Brandhorst et al., 2015; Fontana and Partridge, 2015; Garatachea et al., 2015; Mercken et al., 2012)”

  • Effects of caloric restriction can be long lasting and passed to next generation.

    “The effects of caloric restriction can be long lasting and even be passed on to the next generation (Fontana and Partridge, 2015).”

  • Diet and exercise changes affect insulin/IGF signaling and AMPK and alter expression of many genes.

    “Changes in diet and exercise impact the activity of various longevity regulatory mechanisms, including insulin/IGF signaling and the nutrient-sensing kinase AMPK, and can alter the expression of many genes (Fontana and Partridge, 2015; Garatachea et al., 2015).”

    From The Aging Epigenome (2016) · cites this paper as Fontana and Partridge, 2015

  • Initiation timing and duration of metabolic interventions can alter their effect on longevity, indicating context matters and they are not one-size-fits-all.

    “the initiation timing and duration of these metabolic interventions (exercise and diet changes) can alter their effect on longevity, suggesting that context is an important factor and that these are not “one size fits all” interventions (Fontana and Partridge, 2015).”

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.
