In other words, in front of your long link, with no spaces, add [then right afterwards type in whatever short name you want your link to be called.
Right after that, without any spaces, add](
and right after your long link, add another straight bracket like this)
I just suddenly felt compelled to help this guy out. Hope this isn’t jibberish.
Oh well, even with spaces added, that last part turned into an accidental link. Sorry.
Anyway, thanks everyone for your advice about calcium. I, too, would like to know if there is something interesting about calcium coral. I saw a poster about it in a drug store here recently that make it sound like magic. I’m all for magic!
You get enough vitamin D in your diet? I thought Trinidad was sunny…
People with a predisposition for kidney stones were once told to avoid milk. This advice is no longer given, but taking a lot of extra calcium supplements may not be the best idea for these people. Most folks piss it away no problem.
Perhaps a lot of protein sources contain ample phosphorous? Calcium, phosphate, vitamin D and PTH (parathyroid hormone) have a complex relationship, but more phosphate may equal less calcium in some instances (kids drinking soda).
I know of nothing special about coral calcium? I think you’re better off with the cheapie antacids.
]b]Inconceivable**, How does that site know the absorption values of milk and spinach and all those foods? They give no cites. Coming up with percentages like that as if they are facts is tough. What study could show these numbers to be factual? THen, what studies show that they are factual?
I’m not sure if they were talking about cooked or raw. But anyhow, I’d like to know more about these oxalates. Maybe they bind to the calcium in a test tube, but do they bind under the watch of your digestive system? I am skeptical about things like this being written off so quickly when we don’t even know what all the contents in spinach are (phytochemicals). I’ll keep eating my juiced spinach and we’ll see how long my bones hold up.
Also, how are these bioavailability studies done and by whom? Any chance the meat and dairy industry has a grip on the outcomes?
Every good book on nutrition will mention oxylates and also phytates, which will reduce calcium absorption from green leafy vegetables such as spinach.
Perhaps you should do your research first, and then and only then doubt the results.
Also, see, you cannot find the methods for gathering data on the internet, only the data itself. Oh well. I guess we’ll never know the whole story behind oxalates. I juts have to take the word for it.
Your site is boiled spinach. Mine did give the data for 1 cup of raw spinach. 5oz of boiled spinach is going to be more spinach then a couple of raw handfuls. Spinach shrinks when cooked. I have never boiled it, but even steamed a couple of handfuls would shrink to almost nothing.
My only point was I don’t see a couple of raw handfuls of spinach a night will prevent a calcium deficiency as you claimed. Even your 5oz of boiled spinach completely absorbed wouldn’t be enough calcium for the day.
I only pointed out information about how absorbable it was because you mentioned bioavailability. I have read several books on diet and nutrition for women which have stated the same or similar data. They did the studies using radioactive calcium to see how much was absorbed. I can’t remember anymore then that. I usually skip how the studies are done because I am not a scientist. I just want to know what the scientists figure out. If you want to come over to my house I can show you the books
another spinach site
I know this site isn’t much help. I just wanted to try out my new trick. Thanks Jill!!!
As I’ve argued many times before, you cannot get knowledge or understanding from the Internet, merely facts. For knowledge and understanding you have to turn to books.
The problem is that there are few books on digestion for the layman that are very good. You really have to turn to books aimed at professionals in medicine. There are books written specifically for nutritionists and dieticians that go into much detail, but you may need to go to a medical school library for them. I’ve spent many hours down in the bowels, pun intended, of the local med school stacks doing my reading. Not pleasant, but necessary.
For pure numbers, however, you can’t beat the standard: Food Values of Portions Commonly Used, by Jean A. T. Pennington and Helen Nichols Church. I have the 14th edition. Raw spinach has 51 mg of Calcium per 100 grams; cooked has 33 mg of calcium per 100 grams.
According to the pitchman (“Dr.” Bob Barefoot); coral calcium cures:
-cancer
-diabetes
-multiple schlerosis
-many other diseases!
You can purchase a 30-day supply for only $40.00!
Just for the sake of arguement-how do healthfood stores get off charging so much for calcium? Lime is available at home depot, for $2.27/40 lb. bags!
Because you don’t want to eat lime. You want something that has been purified as much as possible to take out extraneous bits of harmful materials, ground into fine enough powder and mixed with inactive ingredients in such a way that it will dissolve in the digestive system in less than 45 minutes. This is not something you can do at Home Depot.
FDA guidelines, BTW, have a five part per million limit for lead, which can concentrate in natural calcium sources. Several years ago several brands of dolomite and bonemeal calcium were found to have excess lead sufficient to potentially cause lead poisoning in children. As far as I know, all reputable manufacturers have reduced the lead in their products today, but purity of product is a point that can’t be stressed too heavily.
Calcium carbonate is also called “whiting” and is used as a natural, non-abrasive cleaner. Combine with ammonia or oil, it will clean silver and marble without scratching. You can also put it in jewelery cases, toolboxes, and wherever you keep your silverware to avoid tarnishing.
I don’t recall where I’ve seen this information, but I’ve read various health pamphlets which say that magnesium must be consumed with calcium in a 2:3 ratio in order to obtain as much benefit from the calcium as possible.
I recall being told that the max absorption rate for calcium was about 250mg in 3 hours. So don’t take your daily dose all at once.
I’ve also heard that dietary calcium (straight from food) is better absorbed (from any source, including plant) than calcium carbonate.
Anyone know reliable info on those two items? I’d like to know if they are true.
And for the actual data from a real study (yay, not more guessing!)… taking calcium supplements during lactation has almost no impact on the degree of bone loss you have Slight difference, but only in the 1-2% range, not statistically significant). But taking supplements after weaning dramatically increases the amount of bone you get back (at least within the study term). And taking supplements during lactation does not increase the amount of calcium in breastmilk, either, so it isn’t like you are just shunting it to baby during lactation - nobody is benefiting. So, supplements during lactation are pretty much a loss (no benefit to mom or baby), but as soon as you wean, start chewing your Tums again, and your bone density will bounce back faster and farther than diet alone will do.
They don’t know why yet, of course. But the chemical process that harvests the calcium from your body and dumps it to the milk is probably messing with the metabolism of calcium carbonate.
The above study was done with calcium carbonate only. I’d love to see it repeated with calcium lactate…
