Objective:

To propose a theoretical model to measure and intertwine the human food activities that affect the loss or achievement of ecosystem balance.

Methodology:

A documentary review was made on the current eating pattern, its determinants, and the impact on planetary health.

Results:

The transformation of the eating act, determined by different social, economic, and cultural factors, has given rise to unbalanced diets with high consumption of meat, which demand environmental systems. Parallel to this, rates of chronic non-communicable diseases have been increasing, creating a negative effect on planetary health.

Limitations:

This study formulates a theoretical proposal that allows addressing the complexity of the diet and its effect on public and environmental welfare, serving as a guideline for applied analysis.

Conclusions:

The MCS provides a broad and critical vision for the analysis and intervention of socioecological difficulties such as food, providing scientific bases for health professionals, food production, decision-makers, and public policy developers.
