Hi Doc Nolan,

We (the family) might be droppin' in for some Spring Break camping later this week if I can get a couple of days off from work. Hope ya'll are all doing great! I've got a general question about bone health - just suffered my 3rd fracture in 3 years (snowboarding the slopes in Santa Fe ... non-displaced, stable ankle fracture, partially detached tendon [they called it a 'chip fracture'] ... no surgery, no pins ... and just moved from 6 weeks on crutches to the hobbling stage). I don't think it's such a good thing that you get to be on a regular, first name basis with an Orthopedic doc and his whole staff, but that seems to be where I'm at. They say that too much of a good thing is always a problem - in this case, caffeine and alcohol. I've heard that both can contribute to calcium loss in bone structure. I won't publically confess to how much of each I consume, but I'm pretty sure I'm at least 3X over the reasonable limit and the 12-cup carafe on my Mr. Coffee is usually empty by 10:30 AM on a typical work day. I have a widely varied diet, which includes lots of milk or half-and-half in my coffee ... I usually don't use any dairy products in my beer, though. Is there any truth to the calcium loss theory? If so, can it be offset by a calcium/multi-mineral suplement?

thanks,
js

I did a PubMed search for salient articles on osteoporosis and caffeine or alcohol. These are some of the abstracts that were appropriate to your question. It does appear that excess in caffeine from coffee and excess in alcohol can increase the risk of osteoporosis. (Tea interestingly enough seems to offer some protection.) Moderation is the key here. Limiting consumption of these substance to 2 cups of Joe and two alcohol containing drinks (any combination of two, not two of each: two beers, two 6 ounce glasses of wine or two ounces of hard liquor a day) does not have adverse effects. If you find moderation is impossible, then complete avoidance is the best option to choose. Your body habitus is long and lean, with low body mass gives you another a significant risk factor for osteoporosis. Calcium with vitamin D supplementation a well as weight bearing exercises such as jogging and weight lifting 3 times a week should be added to your regimen of regular physical activity.

Thanks,

Those are interesting studies Doc. Since energy drinks and some sport supplements have significant amounts of caffeine in them then some athletes could be at a significant risk of calcium depletion and bone fracture.
That would be a good topic for someone to expound upon if they had to write a master's thesis. hmmmmm.....

Thanks for the links, Doc. I've perused a couple of them and will look at all, but the indicators are that they won't tell me what I want to hear Very Happy

"Best" Calcium supplement; your local HEB has it in the Vitamin section, but you might as well buy them in large quantities online once you get hooked on them. Great for all your female family members as well. Very Happy

I haven't read any of the above links, but isn't there some new data that indicates that actual weight-bearing exercise (as opposed to only aerobic) is necessary to maintain bone health as we get older?

Yes, that is why I recommended "weight bearing exercises such as jogging and weight lifting 3 times a week should be added to your regimen of regular physical activity."

Thanks,

Ack! I guess that I should have said "links and posts". My bad.

Hi Doc ... been awhile ... got another issue I really need help with- Jan '10, had a no-problem physical/no-issues-blood/lap-results check-up. May-2010 - full-blown insulin-dependant diabetic (LADA ... latent auto-immune diabetes of adults). Haven't been on my bike in 2 years. Recently decided I need to remedy that, but ... lots of concerns about hypo-glycemia (after some scary incidents), etc. I would be very grateful for a bit of off-line discussion if possible. Direct email is jsilj1@johnsilvey.net.
thanks,
- js
