Modeling study shows that dietary changes improve health and sustainability in adults, suggesting reduced costs.

This modeling study aims to analyze the transition to healthier, environmentally sustainable diets among socio-economic groups in the Netherlands.
Used food consumption data from 1,747 adults in the Dutch National Food Consumption Survey 2019–2021.
Participants categorized by educational level to assess socio-economic position.
Diet optimization minimized greenhouse gas emissions and maximized diet quality using the Dutch Healthy Diet 2015 index.
Compared costs of current vs optimized diets across educational subgroups.
Dietary changes led to a 19%-24% reduction in greenhouse gas emissions.
Diet quality improved by 52%-56% without increasing median diet costs.
Optimized diets included more vegetables, fruits, nuts, legumes, and fish, but less grains, dairy, meat, and sugars.
Improvements were more significant when optimization wasn't limited by educational level.

Vellinga et al. (2025) studied this question.
