We eat more than enough protein. What we lack is roughage. We're all in on that ultra processed white bread and corn chip stuff with lots of pasta. The main foods we need to eat more of remains as it always has: vegetables and to a lesser extent unprocessed fruits. We also should shift how we consume starches to healthier variants like baked potatoes. But seriously, it's fiber, we don't eat enough fiber

I don’t disagree with that at all. Fiber is massively important.

I suppose what I’m trying to say is, given a constant calorie budget, people would be healthier if they shifted their proportions of calories towards protein and good fats and away from carbohydrates and bad fats. This does not seem like quackery to me, it seems like sound dietary advice.

This is broadly true, and the majority of the information in the new dietary guidelines is more or less in line with what we know already and what was recommended before. Protein is a great energy source that keeps you fuller longer, and is especially important if you're active. But the new recommended range of protein intake is ridiculous. 1.2-1.6 grams per lb of body weight is well above the range that is helpful for bodybuilders, much less average sedentary Americans. Many will meet this with red meat consumption, which has a number of negative health and climate effects that the new dietary guidelines have nothing to say about.

You also really do need fats and carbohydrates for a number of vital body processes, and I think unless they're active and being VERY careful, someone eating 1.6 g/lb of protein will struggle to get enough fat and carbs without introducing a caloric surplus.

That’s frankly an insane amount of protein. I have been getting into weight lifting the past few years and I target 1g protein per kilogram bodyweight. This got me from 165lbs (75kg) to 205lbs (93kg) on a 6’3” (1.9m) frame and it seems to be well supported by numerous scientific studies.

It really depends on your activity level and what your goals are. To quote from your own source "If you’re actively building muscle with strength or resistance training, more protein can help,” said Dr. Dariush Mozaffarian, a Tufts University nutrition expert. “Otherwise, you’re getting enough.”

Most Americans are getting enough protein in their diet because most Americans are less active than they should be and are already eating more than they should be.

Diets should be built around an individuals needs, though fiber is one of the things virtually no one is getting enough of unless your eating like 5 cups of lentils everyday.
