So they brought with it a lot of carbohydrates and fats as opposed.

And what we know is that with the pyramid, they increased their grain consumption by 40%.

They increased their consumption of seed oils by 55%.

the original pyramid.

They made all of those changes.

People say, well, the pyramid didn't cause those changes, but it actually did shift people.

In 2010, the Dietary Guidelines recognized that, and they dropped the pyramid.

They recognized that people had increased their dietary intake of calories by 350 grams.

Steve Simpson from Australia

hypothesized that that was part of a dilution of the protein that the human body, the humans actually eat toward a protein target and basically by diluting the protein in the diet with carbohydrates, we ended up eating more carbs to maintain that protein intake.

The net effect was we lowered the quality of the protein.

We increased our carb intake and increased our calorie intake.

And we started getting our fats.

And basically, that came with trans fats, which were two to three times more toxic than saturated fats ever were.

And so, you know, everything about it distorted the diet.

So in animal foods in general, essential amino acids make up 45 to 50% of the amino acids in that food.

In plant-based foods, it's more like 35%.

So you'd have to eat a lot more of them.

What we know from when people go more plant-based, they decrease the quantity of the protein they eat, and they also begin to decrease the quality because of both essential amino acids and also bioavailability.

If you look at the NHANES data, our national survey data, what you find is that when people shift that way, they shift to eating more grains.
