calcium in homemade chicken broth

[Guest guest]

a woman on the WAP healthy babies group tested her broth for calcium.

below is her post, shared with her permission -

" Since my little baby has been drinking the broth formula in addition

to breast milk for a couple of weeks now, I was interested to find

out how much Calcium/Magnesium exists in it.

I tested my broth using an aquarium water kit. In parallel, my father

took the broth for testing to 2 different labs.

I live in the Netherlands and my father lives in Romania, so we

obviously used different types of chicken and different waters, but

as you will see, the results are strikingly similar.

Both me and my father prepared the broth in the same way: we used all

the bones from one single pasture chicken (aproximately 200g of bones

in total). We cut the bones in pieces as much as we could, covered

them with aprox 2 liters of water, then we added 2 TBS of vinegar

(ACV) and let the bones+water+vinegar stand for 1 hour. Then we

brought the mixture to boil and boiled it on low fire for 24 hours.

With my aquarium kit, I have tested 100mg of Calcium per liter and

150 mg Magnesium per liter.

My father took the broth sample to 2 labs: first, to an industrial

lab, and second, to a food safety lab. The test that came from the

industrial lab gave the same result 100 mg of Calcium per liter.

However, the food safety lab gave a slightly more amount of Calcium

-150 mg of Calcium per liter. The Food safety lab found that in the

broth exists two types of Calcium: the first was in the form of

calcium carbonate ( CaCo3); this calcium was 100mg per liter in the

broth. The second type of calcium was in an ionic form ( Ca++) and

this one was 50mg per liter. Thus, the Total Calcium was estimated to

150mg per liter.

So, my conclusion was that 1 liter of broth made using all the bones

of one pasture chicken( no feet, no head) will probably provide

between 100- 150mg of Calcium per liter. "
