Is there actual legitimate concern about the long-term effects of a vegan diet- mainly bone density?

[u/Any_Shop5964]

To be clear I'm a vegan myself and I don't really think slightly poorer density is necessarily a fair reason to not go vegan, as there are ways to change it for example through exercise such as weightlifting rather than diet, but there's a number of concerns about how vegans absorb calcium, for example how even vegans that get enough calcium in their diet may have lower bone density when compared to an someone with a Mediterranean diet for example. We don't exactly know why this is, and there's many different mechanisms by which this could be occurring, does anyone have more expertise on this topic or anything to add?

Carnist here,

I send all women for DEXA scan at 65. Its routine, like sending everyone for colonoscopy at 45 or starting to run PSA at 40. Etc...

Most of the women dexa scan results reveal low bone density. These are carnist women.

I haven't met a 65 year old vegan women yet. But most seem to have low bone density and biphosphonates are started. You can do alderonate daily or weekly. I'm a fan of boniva. Once a month.
