Here's the real subject of the discussion. It was stated early in this thread that seeds have such a high protein level that they should not be fed in the morning. Also that high protein diets cause fatty liver disease, obesity, high cholesterol, cardiovascular problems, high hormone levels, and aggression. I am unable to find supporting evidence for any of this, and the available information indicates that all of it disagrees with the mainstream medical/nutritional viewpoint. A lot of it is so far off the radar screen that no one else is even talking about it, and it's hard to find information that's remotely relevant. No one else on this thread has provided a shred of backup for any of it either, so at this point I have to conclude that supporting evidence does not exist. This group obviously has good intentions, but IMO they are promoting baseless ideas as scientific fact. This is not the kind of place where I want to hang out so I'm outta here.
The nutrition database information on the protein content of foods is solid and basically irrefutable, but I'm the only person here talking about this kind of data. A safe upper limit hasn't been established for avian protein intake, but the available evidence indicates that the veterinary profession is comfortable with a 30% level and this is not unreasonable. A study on protein and kidney failure was unable to find any problems whatsoever at the 20% level. The reason that protein intake could be an issue with the kidneys is that excess protein is converted to urea and excreted, which increases the workload for the kidneys. Kidneys that are chronically overloaded will be damaged within a few months, and the study lasted long enough to establish that this wasn't a problem even at the 70% protein level.
But there are other relevant factors that basically turn even the 20-30% comfort level into a moot point. Nutrition Data has a search function that lets you get a list of foods in order of their protein content. Food that's in a reasonably natural state has a pretty limited protein level, topping out at about 40% max. To go any higher than that you have to process a food to remove non-protein components like fat, carbohydrates and moisture (of course the moisture content is restored when water is added or drunk). There are few plant foods that exceed the 24% level, and most are well below 20%. The 25-40% range mostly consists of meat and other animal products.
In order to reach a 20% crude protein level in the overall diet, you'd have to feed a bird a diet so unbalanced that the crude protein percent would be the least of your worries. An all-sunflower diet would put you slightly above 20% but everybody knows that is a bad, bad idea. Commercial bird seed mixes top out around 18%, and most are in the 10-15% range. The fat content in some of these mixes is a lot scarier than anything else about them. We have not been given any information on the protein level in the gloop recipe so we don't know how it compares to an ordinary seed mix.
