A healthy guideline

Global ill-health costs from diabetes alone are similar to the total value of farming in the global economy.

• Researchers calculated that producing unprocessed red meat has the highest impact on all environmental indicators.
• Food with medium environmental impacts or not associated with ill health, such as refined grain cereals, dairy, eggs, and chicken, could help improve health and reduce environmental harm if they replace foods such as red meat.

Producing a reasonable guideline for a healthy and sustainable diet would put the world and its people in a much better place.
