I feel like the world is constantly conspiring to get me to eat bacon. That was my first thought when I saw this new study from France claiming that a plant-based diet is not actually the planet-saver we all thought. (My second thought was: WTF, I don’t want to eat bacon.)

The study followed nearly 2,000 diners who self-reported their meals to scientists at the National Research Institute of Agronomy in Marseille; the researchers then tried to determine how much greenhouse gas was emitted in production of the most commonly consumed foods. Let the fuzzy math ensue! Reuters reports:

Overall, about 1,600 grams of carbon dioxide were emitted for every 100 grams of meat produced. That’s more than 14 times the amount of greenhouse gas emitted during the production of fruit, vegetables and starches. It’s also about 2.5 times as much greenhouse gas as that generated by fish, pork, poultry and eggs.

That gap narrowed, however, when the researchers looked at how many grams of carbon dioxide were emitted per 100 kilocalories (kcal) — a measure of energy in food.
