food to begin with, and then you've got all that packaging to deal with.

I want to talk about the food system a little bit, too, because it's so relevant to this.

The easiest way to describe the food system is, again, with corn.

Because if you look at the 12 billion bushels of corn that are produced in the United States every year, roughly 45% of them

of that corn is used to feed animals.

Another 45% is used to make ethanol for automobiles.

And don't even get me started on that.

I think it's just crazy.

Leaving maybe 10%.

of the corn that's produced in the United States as food for people in all its forms.

Not only corn on the cob, but corn ingredients, high fructose corn syrup, all of that falls into that 10% category.

We don't have a food system that's aimed at producing food for people.

We have a food system that's aimed at producing feed for animals and fuel for automobiles.

But the emphasis on animals is not very good for our environment because the production of beef causes the largest release of greenhouse gases of any other food in the food system by a very large margin.

So we would be much better off eating—

diets that had more plants and less animal, not no animal necessarily, but certainly a lot less.

And that's where the triple duty dietary advice comes in, because the diet that is best for preventing hunger, preventing obesity and its consequences is

and preventing climate change is one and the same diet, which is to eat real food, processed as little as possible, with a big emphasis on plants.

And it's the same diet as the one that's best for health.

Isn't that nice?
