    Not sure if this is the right place........can't find one for Nutrition(?)
    I know that osteoporosis is a worry for some very severe patients and those who are mostly bedbound.
    I saw this on some program on the telly; they claimed to have even managed to reverse the damage done so thought it might be of use.

    "There has been quite a bit of research done on dried plums (aka prunes) and their effects on bone health. Some of the results have been quite impressive. One study, for example, found that subjects who had already experienced substantial bone loss were able to completely reverse these losses by eating prunes every day! Others show that eating prunes can help prevent the bone loss from occurring in the first place."

    https://www.scientificamerican.com/article/can-prunes-reverse-bone-loss/

    The only research I've found is this:

    https://www.ncbi.nlm.nih.gov/pubmed/28422064

    eta:
    "In a clinical study of 58 women, eating 100 grams of dried plums per day improved bone formation markers after only three months, compared to a control group served 75g of dried apples"

    @Sly Saint - that's interesting. I used to try and get exercise whenever I could because of the potential risk of osteoporosis but I've not been able to do as much in the last decade.

    My mother is very fond of prunes. Maybe I should nab some. ;)

    I got quite excited till I read a bit further.

    You left out this bit:

    ''The only problem is that these studies were all done in mice and involved eating prunes as 25% of the entire diet. I’ll just give you a moment to contemplate the potential impact of that.''

    Is there a mechanism provided, does it activate osteocalcin?

    Might be quite useful for me - could cut out the Cosmocol :sick: that I have to take every day! :) (For diverticulosis :eek: )

    So, in conclusion, dried apples, really, really bad for bone health, at least 58 women should stop eating them.

    The study is at http://sci-hub.io/10.1089/152460902753473471 and isn't very convincing. 20 of the 58 women dropped out, 5 of them specifically due to GI effects caused by the prunes.

    The controlling of the diet was pretty poor as well, since the apple control group dropped their intake of calcium, phosphorous and potassium quite a bit. The prune group also reported increasing their calorie intake by nearly 400 calories per day. So there were some important dietary factors at play other than just prunes versus apples.

    They don't seem to correct for making multiple comparisons, meaning it's likely that the difference in outcomes were due to random chance. They also never seem to say how many people were initially randomized to each group, raising the possibility that all or most of the dropouts were from the prune group.

    "Drugs used to treat weak bones in elderly patients suffering from osteoporosis may actually make them weaker, research suggests.

    Scientists at Imperial College London examined the bone structure of hip-fracture patients who had been treated with bisphosphonates.

    They found evidence the drugs were linked to microscopic cracks, making bones more fragile and prone to break."

    Perhaps they didn't eat enough apple? They only got 75g of dried fruit whereas the prunies got 100g. I though the whole point of a control group was to make such factors equal between groups. 100g of prunes is a lot, to my mind. How much is that in terms of fresh plums? I find dried fruit is only really palatable in quantities like 20 or 30g.

    This has been known for some time, in fact they seem to cause jaw fractures...
    i remember reading they were approved because no better option was available, not because they work great.
    They basically prevent bone resoption which should help because bone formation is impaired as people get older and the ratio becomes unbalanced. Frankly at this point we have Vitamin K2, it activates osteocalcin so with vitamin A and D it should be recommended for all seniors and bisphonates banned.

    I laughed at that at first, then realised on my current meagre food rations, it'd probably only be around 15 prunes.

    I think they also make the bones scans look better. It is just that the bone is brittle and prone to breaking.

    A few prunes a day shouldn't hurt and might help. They contain phytonutrients similar to the much-touted ones in blueberries. A good bone building vitamin/mineral supplement would probably be better, though.

    I don't care how it makes things look, i care that it works for what its supposed to treat. Though that distinction is lost on many doctors.
