I haven't fully researched this site, but I would be wary of it. They seem to be focused a lot on selling vitamin d supplements.
The analysis about the apparent discrepancy between children with multiple fractures not having vitamin D deficiency yet more and more researchers reporting rampant vitamin d deficiency appears to be taking statements out of context and comparing apples with oranges. We'd need to examine the papers that are being referred to, but I believe that a lot of children have low vitamin d levels and it's not yet really understood how much vitamin d someone does need in their system other than certain extremely low-levels correlating either with rickets or other bone problems. So, more researchers could be reporting rampant deficiency but that doesn't mean all those children are suffering multiple fractures due to that 'deficiency'.
But if you write it the way it's written there, you're certainly going to sell more vitamin d supplements through your site!
But also, if Sherin's case goes to court, we can probably expect experts testifying on this subject and a confused jury not knowing what to make of experts who appear to give conflicting expert knowledge depending on whether they're testifying for the parents or the DA. I hate it when this happens and a jury is supposed to decide when they haven't a clue what they're being told.
Undoubtedly Sherin died at the hands of one or both of her so called parents. WM admitted to that and hiding/removal of Sherin's body.
SM has been charged with child endangerment because of them leaving Sherin home alone for an hour and a half. So far that's all we have got legally, and the Dr. reporting to CPS as they have to do if they suspect abuse.
The article i posted up was interesting and there are quite a few other studies done in medical papers/studies of children born in third world countries with some of those diseases that have been caused by malnourishment, which can have lasting effects on a child that refeeding can't fix. You can google about all that and there is plenty of info out there on it all.
And Sherin did come from India where she was malnourished and her growth probably stunted as well because of it. All IMO.
