To be climate-friendly, food-based dietary guidelines must include limits on total meat consumption - modeling from the case of France
Résumé
The average greenhouse gas emissions of the observed diets was 4.34 (SD=2.70) kgCO2eq/d, with an energy intake of 2080 Kcal/d The diet that closely resembled the observed diet under the dietary guidelines, nutrient and acceptability constraints had emissions of 5.15 kgCO2eq/d .
Modeled diets that complied with dietary guidelines and nutrient and acceptability constraints had emissions ranging from 1.16 kgCO2eq/d to 6.99 kgCO2eq/d . All modeled diets had higher consumption levels of fruit, vegetable oils, pulses, and wholegrain products.
The diets minimizing and maximizing greenhouse gas emissions, and the range of modeled diets in between, differed in their level of beef/lamb, refined cereals, fruit, pork, and snack products.
The level of meat, especially beef/lamb, explained most of the difference (up to ≈85%) in greenhouse gas emissions between the models.
The level of total meat consumption decreased progressively across models that imposed a decrease in greenhouse gas emissions.
