The study 'Double Pyramid: Healthy Food for people, sustainable food for the planet' indicates that foods with higher recommended consumption levels are also those with lower environmental impact. Contrarily, those foods with lower recommended consumption levels are also those with higher environmental impact.
The 'Double Pyramid' model combines the well-known food pyramid with the environmental pyramid, based on an estimation of the environmental impact of each foodstuff in terms of generation of greenhouse gases (Carbon Footprint), consumption of water resources (Water Footprint) and use of territory (Ecological Footprint).
