Hi, I was having raw (cow's) dairy products which I thought I was handling fine even though I had experienced some digestive disorders and what appeared to be food sensitivities. I did an allergy test and it appears that I am mildly allergic to cow dairy. Goat milk was supposed to be ok (different type of casein) but after 2-3 days of eating goat yogurt I notice I have a stuffy nose and post-nasal drip so it appears that goat milk is also a problem.
I'm looking for alternative good sources of calcium. I'm allergic to almonds and I don't quite picture myself eating canned sardines everyday. Leafy greens are a good source but some also contain oxalic acid that binds with calcium and therefore makes it unavailable for the body. I'm ok with bone broths and nourishing herbal infusions.
Anybody tried homemade eggshell calcium powder (I'm mildly allergic to chicken eggs but the shell is 100% calcium and I'm about to get some duck eggs delivered which have a thicker shell) ? http://nourishedmagazine.com.au/blog/articles/how-to-make-calcium-using-egg-shells
What about those bone meal tablets? Anybody using them?
Any other suggestions?
Vitamin D (cod liver oil) plays a role in calcium absorption but I read that if you don't already have enough calcium in your body to start with, it will be taken from your bones & teeth.
Thank you for your precious help.
Mineral water. It would've been our ancestors' source for nutrients like magnesium, calcium, and lithium. If I drink two bottles, I get 74 percent of the RDA, which is probably overstated anyway. I think it's pretty bioavailable too, but I have to admit that I haven't read too much on it. Calcium from dairy isn't well absorbed though, and calcium from leafy greens is sometimes tied up with oxalates, like you mentioned. Sardines and bone broth are really the only other sources I know of.
Bonus! It's usually packaged in glass, so you get to avoid the bpa and estrogenic compounds found in plastic.
