High Ultraprocessed Food Intake Linked to Lower DNA Methylation

7 minutes

Ultraprocessed foods alter DNA methylation patterns, silencing protective genes and activating harmful ones, creating cellular dysfunction that begins before visible health problems appear in both adults and children
A study of 30 adult women revealed those consuming 45% of their daily calories as ultraprocessed foods showed hypomethylation in 80 genome regions, affecting genes linked to fat storage, insulin sensitivity, and cancer progression
Research on 3,152 European children found that ultraprocessed food consumption caused consistent DNA methylation changes affecting thyroid function, liver health, DNA repair, and stress-response genes
Methylation changes occur even in healthy-weight individuals, demonstrating that genetic damage accumulates years before traditional metabolic markers like blood sugar, cholesterol, or body fat show problems
Breaking ultraprocessed food addiction requires restocking your pantry with whole foods, adding protein and fiber to meals, reading ingredient labels carefully, and building supportive communities focused on healthier eating
