I am the one that says that the gloop should be 50% grains/beans (I should add seeds here, too as the gloop does contain flax and sesame seeds) and 50% veggies but, like Wolf, I also feed raw produce and seeds/nuts on a daily basis (and right now, they are also getting mealworms AND sprouts four times a week) so it's not as if the birds diet was 50% grains. Furthermore, this 50% "grains" does not only include the small white beans, the black lentils and the seeds but also the black, red and wild rice which have no gluten AND, I am now using ancient grains which are naturally lower so, as you can see, the actual percentage of 'gluten' in their diet is much lower.
Now, the 'cooked grains are not natural to parrots' is a fact but then you give a recipe that has 20% beans which are even more unnatural to a parrot's diet than cooked grains because parrots, at least, do eat grains in the wild but never, ever eat pulses. Let's face it, we can't give them their 'natural' food so we all have to make do with what is not only available but also practical. Very few people can prepare a nutritionally balanced, completely raw diet for their birds. And, in reality, if we were to get really 'technical' about these things, your germinated and soaked seeds and nuts are not natural to their diet, either. Parrots don't eat germinated or soaked seed in the wild, they eat the seed or the nut right off the plant. Mind you, I am not saying your diet is unhealthy (I am sure it is), only that is also not natural. And when we talk about substantiating and who does it and who doesn't, I think you are been a bit unfair. It's very seldom that I don't post or later provide a link when requested (usually by you

). You, on the other hand, hardly ever do. Whenever I have asked you, you reply that you have given us enough info for us to do the search on our own or mention multiple postings which, to be honest, nobody else seems to have seen (not that this means you haven't, only that they cannot be used as proof) and, in two occasions, posted links that were advertisements of products -which are useless as proof of anything.
As to the 70's reference on people beginning to feed grains to their parrots, that's when pellets came out which are all made with grains as well as when people started feeding them human food like pasta, pizza, bread, etc. even monkey biscuits! Before that and as far as I know, they were fed seeds and nothing else.
And, to tell you the truth, I would not feed the recipe Dr. Mc Watters is giving, either, and I'll tell you why:
- She uses pinto, black-eyed, etc beans which are the highest on the toxic lectin (instead of recommending white beans which are the lowest) and says to boil them for only 10 minutes when all literature says that they need to be boiled for 30 (simmering is not good enough, apparently).
- She uses brown rice (which we all know is way too high in arsenic and not as nutritious as red or black rice) and triticale, a man-made second generation hybrid that is practically only used as animal fodder (I only use and recommend human grade).
- She mentions a grand total of three greens: parsley (which I don't feed at all as it is, by far, the highest of all plant material in oxalic acid), and comfrey or mustard greens (mustard greens been another doozy in oxalic acid). She states that comfrey provides B12 which, for one thing, it's not necessary to supplement to birds because they produce it themselves and, for another, even if it was, comfrey was not going to do the trick as the amount of comfrey that would need to be consumed is huge and unhealthy (4 lbs daily for humans! - it destroys the liver).
- Veggies are good but I am surprised she uses white potatoes (she does say to put them there with the skin but I have never, ever, ever seen any of my birds eating it. All they eat is the white 'meat' which is not much more than carbs) Also, why chayote? I am puzzled by this choice and she doesn't explain it.
- And I would never feed algae or kelp to my birds (way too high in iodine and talk about unnatural!)
Also, can you provide a couple of reputable links indicating that cooked grains should be removed after two hours? Because, although I have seen references to the 'refrigerate after two hours' is always used for food in general (which includes meats, fish, etc), I have never found anything that supports this specifically for cooked grains. Going by my research (but I could be wrong so if you have a good link to correct me, please provide), the ONLY real danger is B cereus but, even if it happens, we are talking about diarrhea (unlikely as the high heat of cooking kills the spores) or vomiting for 24 hours and that's it, more inconvenient than anything anywhere near fatal and, for what I can tell, my birds have never gotten it (I have never, ever had a single parrot vomiting). The other thing is that it appears on almost every food we eat (it's in the soil) but it requires a series of conditions for it to reproduce so much that it actually becomes dangerous -like a dry medium is worse than wet and oily been worst; it requiring low heat cooking for the diarrheal strain spores to survive and quite a bit more than just 2 hours at temperatures higher than 86 degrees for the bacillus colony to grow large enough to actually cause any harm at all, etc. It's known as a common cause of 'food poisoning' from fried rice (oily medium at temperatures of more than 86 F -which they call 'abusive temperatures'

- for many hours). As a matter of fact, it appears that a bit of it is actually beneficial as it 'fights' salmonella in the gut!
