I was reading up on the GAPS diet the other day, and I came across the usual line "it is important to not heat broth in the microwave because it kills the nutrients". It is my understanding that nuking veggies can reduce the vitamin load significantly (but so can boiling them in water on the stove top). It seems to me that minerals shouldn't be prone to the same type of degradation, and I thought bone broth was mostly about the minerals.

There are no studies on broth and a lot of studies on microwaving nutrients were done over a decade ago and microwaves have gotten more sophisticated since then. But even this study from 1994 shows that microwaves have little impact on minerals:

Microwaving broth is supposedly bad because it can convert L-proline to D-proline which could be toxic, at least according to this article: http://augmentinforce.50webs.com/Gelatin.htm. It cites this paper from The Lancet as evidence, which I unfortunately can't access: Lubec, G, et al. Amino acid isomerisation and microwave exposure, Lancet, 1989, 2, 8676, 1392-1393.

I know Kurt Harris does not like microwaving. But microwaving is just not avoidable if you're storing stuff in your fridge. It may not be Paleo but is essential, if you wanna eat Paleo and save time.
I mean, just about everything I eat is microwaved. I even microwave my coffee and green tea. I recently switched from boiling my yams and sweet potatoes to microwaving them.
