OK, his studies beat my anecdotal bias.

...That being said, I will continue to eat breakfast cereal with milk pretty much every day (as I have since I was very very young), and be strongly tempted to attribute my own lack of having ever broken a bone to that.

The other anecdote I have in my favor is coming from a farm family that raised chickens. I grew up in a prairie grassland area (converted to irrigated farmland thanks to aquifer access), while my cousins lived a couple hours away in limestone hills ranchland. Both of our families raised free range chickens.

Our chickens produced very thin-shelled eggs, and displayed behavior to suggest they were calcium-deprived. For example, our chickens wouldn't cannibalize their own viable eggs, but if we threw empty shells to them they would fight to eat the shells. Same but to a lesser extent for leftover bones, etc. (I assume they fought less over these because bones are harder to near impossible to break down with a beak). On the other side of the table, we sometimes exchanged eggs with my cousins, and their chicken's eggs were always extremely thick-shelled and hard to crack open.

When I asked about that, my folks told me (and later my Biology teacher confirmed) that was because the sod/soil around my home and flora and fauna growing from it contained very little natural calcium. Chickens raised in our area would often be supplemented with commercial feed that contained extra calcium, but we let ours range for food and eat table scraps; almost never supplementing their food with any commercial stuff. But the limestone (aka calcium carbonate) around my cousin's house contained very high amounts of natural calcium, which was naturally infused into the plants / grains / insects that their chickens ate, giving them incredibly thick shells.

So, I guess that while calcium intake apparently doesn't have a very statistically significant impact on human bone growth, I think that it must have a much more significant role to play in egg thickness if you happen to be a chicken... At least if you compare extremes of low natural calcium diet versus extremely high natural calcium diet.

Seems like a pretty good analysis.

Taking just about any supplement just for the sake of it, is pretty much like eating lollies, except they aren't tasty, and can have side effects. It's not really that calcium supplements are the main problem, it's that people are gullible.

What are the best things one can do for bone health?

1. weight bearing exercise (bones respond and become stronger)
2. vege's - especially leafy green vege's
3. vit d - get some sunlight most days

and... avoid smoking.

It could also be my monitor causing the subtleties to stand out, but If you kind of step back and look at him, he's quite yellow in some areas, quite red in others, and you can see brush strokes between some of the layers of makeup.
