That’s a very different food pyramid from the one that I was taught at least. The 90s/2000s food pyramid made no distinction between different kinds of meats but did make a distinction between grains, fruits, and veggies, with grains as the base of the pyramid.

Your food guide looks different than mine. Notably, yours has a distinction between meat, poultry, and seafood where mine are all lumped in as one category that also includes legumes.

For what it’s worth, I believe this guide has been fully discredited. There was a considerable amount of lobbying to present certain foods prominently.
