Osteoporosis & Osteomyelitis Research

An interesting article regarding research into using a nanomaterial to reverse the bone damage caused by osteoporosis and osteomyelitis.

There will be a lot of happy people if it comes to fruition.

An article regarding weightlifting helping combat osteoporosis.

My wife was recently advised to do some weightlifting, which she has commenced doing, so as to help with her osteoporosis.

An article regarding treating osteoporosis.

A couple of articles regarding treating osteoarthritis.

Researchers find that consuming too much coffee may increase the risk of developing osteoporosis.

Note that the trial is only assessing calcium loss in urine, and has not been correlated directly with developing osteoporosis. It may or may not be relevant to general health. It may be relevant on an individual basis, whether genetic, dietary or other factors apply.

The next question is how much caffeine was required to produce an increase in calcium in urine?

The trial results are based on a daily consumption of 800mg of caffeine a day. With a typical single shot of Espresso around 60mg that’s an expensive coffee habit. The possible effects if any of more modest consumption is not considered.

It’s not really about coffee, but caffeine!

While tea drinkers were not mentioned, a well brewed cup of black tea can also contain high levels of caffeine. 40mg or more per cup. More if brewed for longer, and more if like me, you like a large mug rather than more petite fine bone China.

And Food Standards Australia has a simple chart which compares commonly consumed product caffine levels (note: standard serving size vary)…

Australian expressos FSA have data on must be stronger at around 145mg per 50mL serve.

A double shot perhaps?
A single is 25-30 ml.

The key point I hoped to make was that the study does not demonstrate a link between coffee (caffeine) consumption and osteoporosis.

A second observation is that most of us consume caffeine from more sources than just coffee. The study does not answer the question as to at what level caffeine consumption becomes a risk in respect of developing osteoporosis. Noted FSA have advised a recommended maximum level of consumption. It’s half the level used in the referenced trial. Perhaps the trial should have dosed at 400mg of caffeine daily instead of 800mg?

On caffeine in coffee:
A suspicion is that we will find numerous variations on what a typical espresso is,

The amount of caffeine extracted depends a little on the beans and grind, and more so on the water temperature and time taken to complete extraction. Any one with a Nespresso pod machine will attest a single shot is delivered in a very short bust compared with a steady slow 30 second pump operated by a pro.

P.S.
Perhaps for FSA only the best will do? Not all baristas are created equal. The tradies in the street need to suffer the quick grab and go from the local servo or 7-Eleven. Should individual coffees come with a caffeine score similar to the kJoules on the fast food menu?
