Maar wanneer de eierenschaal puur calcium is...hoe veranderd de structuur van calcium met verhitting?
Ik kan het nergens vinden, maar misschien kijk ik verkeerd?
In 'n ander eieren topic had ik de vergelijking gemaakt van rauwe bot en gekookte bot,
wanneer je dat naast elkaar legt, dan is het verschil duidelijk te zien.
Maar wanneer ik 'n rauwe eierenschaal en 'n gekookte eierenschaal naast elkaar leg,
dan zie ik geen verschil.
Dus voor mij maakt het echt niet uit of ik rauwe of gekookte eierenschalen gebruik.
Hier nog wat meer info over eierenschaal....
Eggs: High calcium!
Just because we humans don't normally eat the the whole egg, shell and all, doesn't mean that eggs as a whole, natural food are not extremely high in calcium.
The fact is, dogs can & do eat the whole egg, with the shell.
And that shell is pure calcium, in addition to the calcium in the egg yolk & white inside.
This is no different from recognizing sardines (w/bones) as a high calcium food -- except that of the two, eggs w/their shells are the higher calcium food.
The difference between eggshell + egg inside and meat + bones is this:
Eggs contribute a fair amount of calcium through yolk & white,with the shell then delivering a whopping additional amount of calcium -- and virtually NO phosphorous.
If dogs ate eggshells raw, which they probably would along with the eggs, it is unlikely that they would digest all of the shell, making the calcium level even closer to ideal.
Boiled/baked & ground eggshells,pure calcium, given by owners along with eggs can be given in tiny, tiny amounts to meet calcium needs.
I choose to provide eggshell cooked & ground, because it eliminates any risk of salmonella poisoning and sharp perforating particles going through my dog's system. I cook them because I can, it's easy, & it's safer. (As a risk/benefit analysis, I see risk and little benefit to doing otherwise.)
Meat offers tons of phosphorous & is calcium poor, with the bones then delivering BOTH calcium & phosphorous. Yet that extra phosphorous isn't ideal.
Commerical bonemeal, cooked/processed, is an even worse idea. It is highly contaminated with lead at extremely toxic levels -- human grade or not. Large grazing animal bones are also lead contaminated across the western world. Dr. Weil's own research backs this up.
Eggs are also the #1 protein source for dogs, highest biologic value & highly digestible.
They also offer rich lecithin, Vitamin A, choline (brain food), EFAs, vitamin B12, other nutrients, and are primarily monounsaturated (& unsaturated overall).
An outstanding book on calcium richness in whole foods is Calci-Yum!, by Rachel & David Bronfman. The most up to date nutrient resource, which I recommend & keep at hand is The Nutritional Almanac, 5th Ed. (2002), by Lavon Dunne.
