In the PM article pack on Nightshades, Dr. G cites multiple instances where nightshades were cause for concern because of their Vitamin D concentration. The remaining articles in the pack never expanded on the dangers of the Vitamin D in nightshades. I've done some poking around, and I haven't been able to find any detail as to why Vitamin D in nightshades might be a danger, and I actually found this article
(wfs), which says high Vitamin D levels are actually no longer a concern pertaining to nightshades. Any insight would be appreciated.
