> I remember reading that Americans eat 2x the protein they need on average

Not anymore, because the new recommendations (1.2–1.6 grams of protein per kilogram of body weight per day) are up to double the old recommendations (0.80 g of good quality protein/kg bodyweight/d - https://www.nationalacademies.org/read/10490/chapter/12).

I have no idea which one is better for the average person, just thought this was funny. If everyone is eating double the recommendation, just double the recommendation, problem solved.

According to Grok, it's (probably) way more than 3x.

I haven't bothered checking with reliable sources but according to Grok, the average American consumes 3.2x the required amount of proteins from animal produces alone.

Growing up, I was taught the grains were at the bottom of the food pyramid. I actually agree that the new food pyramid is a right step when it comes to nutrition
reply
Grains actually should be the bottom of the food pyramid, just not the grains represented in the old pyramid.

Peanuts, lentils, oats, peas, chickpeas, beans, etc. All grains that are both healthy and safe to eat a lot of.

reply
"Grains" usually refers to cereal grains. Everything you listed except for oats is typically classified as a legume or a pulse, not a grain.

And meat should be much less present too. Animal produce in general.

Protein intake should come from both vegetables and meats (to the tune of 500g to 600g per person per week, as a rule of thumb).

But the new pyramid is pretty similar to the old pyramid. From the page:

Grains: Target: 2–4 servings per day.

Vegetables: 3 servings per day.

Fruits: 2 servings per day.

The old pyramid (https://en.wikipedia.org/wiki/Food_pyramid_(nutrition)#/medi...) recommends 3-5 veg (same/more), 2-4 fruit (same/more), more grains, and is still relatively protein heavy (4-6 between meat and dairy).

It's basically a scene from The Office. https://www.youtube.com/watch?v=lC5lsemxaJo

To me, the actual food pyramid picture from that campaign conveys the wrong idea, to the point that it's in fact detrimental.

Yes; that's why the Obama administration changed it in 2011 to be a plate instead of a pyramid.

This is wrong. Protein displaces other macros, ie carbs and fat. We get too much fat and carbs.

A very good balanced take on the new guidelines can be found on “talking with docs” YouTube channel. Even the vegetarian doc agrees with prioritizing protein over carbs and fat. The big disagreement they have is the emphasis on the food industry, especially meat and dairy.
