new research debunks trad views on nutrition

There is also the complication that:

a) Not all protein is "the same", and there are a handful of studies showing that chickens, at least, can have difficulty in optimizing their critical amino acid intakes in the presence of a cafe of moderate to high calorie foods

and

b) studies have shown, again and again, that critters (us, chickens, others) ability to self regulate intake gets "wonky" once our daily caloric needs are met. With that understanding, seeking micronutrients in foods of low caloric density makes very good sense since it allows the eater to address both needs while staying near their desired caloric target.

So eat your veggies first???

[Edit: and I've not watched the YouTube video, but the simple fact that its posted on Youtube makes me doubt its veracity]

What the studies I've read suggest is it's the amino acid profile rather than the crude protein content that's important. Yet again, it is quite complicated but the studies found that if the amino acid profile was maintained at differing crude protein levels egg production and hens weight were not adversely affected by lower crude protein content.

I'll dig it up. The early cafeteria studies support your claim - I've repeated it myself and linked those studies approvingly. There are a few more recent studies that found less than optimal AA intake where the "cafeteria" provided high energy options holding key aminos.

I read it as a caution to not put all one's nutritional eggs into a single ingredient basket
