Dietary interventions (caloric restriction, high-fat, high protein-to-carbohydrate ratios, and specific micronutrients) administered during critical developmental windows (puberty, pregnancy, or lifetime) can induce transgenerational epigenetic modifications that protect offspring against environmental toxins.

To potentially protect future generations from environmental toxins, parents should consider adopting protective dietary patterns—such as high protein-to-carbohydrate ratios, caloric restriction, or specific micronutrient supplementation—during critical life stages like puberty, pregnancy, or throughout their lifetime. These dietary choices can induce epigenetic changes that may persist for multiple generations.

ModerateSupportsMEDIUM confidence
Potential evidence in the primary literature supports that caloric restriction, high-fat diets, high protein-to-carbohydrate ratios, and dietary supplementation protect against environmental toxins and strengthen these effects on their offspring’s epigenome.
