And the emissions might not come from where you think.

Mostly that’s because those people eat a lot more meat than the others, especially methane-spewing beef. Animal protein jacks up the emissions for the top consumers, while the ecologically-minded folks at the bottom consume more plant proteins.

In part, that may be because the work is just so complicated. To come up with estimates, the group had to link several large databases of information. The NHANES survey results can tell you what a broad spectrum of American plates look like on any given day, though it’s worth noting that NHANES looks only at the most recent 24-hours’ worth of food, so not everyone in this study who said they ate a lot of beef necessarily eats that much all the time .

And that’s just the fruit and vegetable part of the equation. Poultry is a whole other story, since you have to factor in the feed production. Beef is the same deal, with the added impact ofThat all has to be calculated for every component of every food. If you report that you ate a pepperoni pizza, these researchers had to find a reference recipe for pepperoni pizza and figure out how many grams of pepperoni sausage, tomato, flour, etc. went into that slice.

And by the way, though there are other solid reasons to eat organic veggies or pasture-raised beef, Heller says those choices don’t necessarily mean fewer emissions. “Often times those are the things that people’s imaginations jump to, because those are the kinds of choices they’re presented with in the store. Those are small differences, though, and they’re relatively small compared to the large differences we see between food types.
