Abstract

Background: Dietary composition can modify gene expression, favoring the development of chronic diseases via epigenetic mechanisms. Objective: Our study aimed to investigate the relationship between dietary patterns and NR3C1 gene methylation in users of the Brazilian Public Unified Health System (SUS). Methods: We recruited 250 adult volunteers and evaluated their socioeconomic status, psychosocial characteristics, lifestyle, and anthropometrics. Peripheral blood was collected and evaluated for cortisol levels, glycemia, lipid profile, and insulin resistance; methylation of CpGs 40–47 of the 1F region of the NR3C1 gene was also measured. Factors associated with degree of methylation were evaluated using generalized linear models (p < 0.05). Lifestyle variables and health variables were included as confounding factors. Results: The findings of our cross-sectional study indicated an association between NR3C1 DNA methylation and intake of processed foods. We also observed relevant associations of average NR3C1 DNA across the segment analyzed, methylation in component 1 (40–43), and methylation in component 2 (44–47) with a pattern of consumption of industrialized products in relation to BMI, serum cortisol levels, and lipid profile. These results may indicate a relationship between methylation and metabolic changes related to the stress response. Conclusion: These findings suggest an association of methylation and metabolic alterations with stress response. In addition, the present study highlights the significant role of diet quality as a stress-inducing factor that influences NR3C1 methylation. This relationship is further linked to changes in psychosocial factors, lifestyle choices, and cardiometabolic variables, including glucose levels, insulin resistance, and hyperlipidemia.

  • Prevention and treatment approaches tend to span multiple levels, including trauma-focused therapy, attachment and relationship-based interventions, and broader strategies that support regulation through sleep, stress management, and health behaviors.

    “Prevention and treatment approaches therefore tend to span multiple levels, including trauma-focused therapy, attachment and relationship-based interventions, and broader strategies that support regulation through sleep, stress management, and health behaviors (19, 125–135).”

  • Consumption of industrialized foods such as sausages, sugary drinks, and chocolate-based products has been associated with increased NR3C1 methylation.

    “In this context, dietary patterns may also play a role, including the consumption of industrialized foods such as sausages, sugary drinks, and chocolate-based products, which have been associated with increased NR3C1 methylation (129).”

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.
