Brief Summary

This study aims to evaluate the impact of a community-based nutritional intervention based on the Planetary Health Diet on dietary patterns, gut microbiota composition, and health indicators in adult women living in rural communities in Querétaro, Mexico. Participants will receive nutritional education, individualized counseling, and practical workshops focused on improving dietary habits and promoting sustainable food choices. The intervention is designed using behavioral and community-based approaches to facilitate long-term adherence to healthy and environmentally sustainable diets. Outcomes will be assessed before and after the intervention, including changes in diet quality, anthropometric measures, gut microbiota composition, and environmental impact indicators such as carbon footprint, water use, and land use.

Outcome Measures

Primary Outcomes (1)

• Change in adherence to the Planetary Health Diet

  Adherence to the Planetary Health Diet will be assessed using the EAT-Lancet Diet Index (ELD-I), which evaluates compliance with recommended intake ranges for key food groups and provides a composite score reflecting diet quality and sustainability. Scores range from 0 to 14, with higher scores indicating greater adherence to the Planetary Health Diet and a more sustainable dietary pattern.

  Baseline to post-intervention (approximately 12 weeks)

Secondary Outcomes (8)

• Changes in gut microbiota composition

  Baseline to post-intervention (approximately 12 weeks)

• Change in dietary carbon footprint

  Baseline to post-intervention (approximately 12 weeks)

• Change in dietary water footprint

  Baseline to post-intervention (approximately 12 weeks)

• Change in dietary land use

  Baseline to post-intervention (approximately 12 weeks)

• Change in total energy intake
