Bad to heat broth in the microwave?

Answered on August 19, 2014
Created September 23, 2011 at 6:58 PM

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.

James, some of the magnesium probably dissolves into the steam that is produced.

Isn't aspic pretty much just jelled broth. That's one of those foods from the 1950's and before that I was hoping would come back with martini bars.

Where would magnesium go though? It's an element... it just doens't disappear. (Seriously :/)

I still microwave it but mix broth with my veggie soup. The broth is thus diluted and I put some nori (seaweed) on top and some steamed kale, so there will be lexx exposure for the zapping.

It's in constant use, and sometimes I use it to reheat my coffee, which became too arm for me to drink after I'm done with everything!

When I eat breakfast, the microwave is being used nonstop. 2 minutes to defrost my bacon. 3 minutes to make scrambled eggs. 4 minutes to heat my bone broth. Then, if still hungry, 6 minutes on each side to microwave my sweetpotatoes.

Microwaving is avoidable if you'd got a few minutes. I broil my left-over meat (5 minutes) and I heat leftover soups and sauces in a saucepan (also 5 minutes).

One thing many seem to mix is broth and stock, stock is only bones but broth has meat too, much better flavor.

ofcourse vitamin c is no concern of broths. Most stocks are cooked to death anyway, so no vitamins in there propably.

Well thats just only magnesiun, a mineral, surely there would be quite different if the graph was about some delicate water soluable vitamins like C.

It's certainly more likely to preserve them than boiling them on the stove.

Good info Melissa, thanks! Just after I asked this, it also occurred to me that gelatin and marrow fat are the other major broth inputs to the diet. Any idea what might happen to the gelatin, and the fat soluble vitamins in that lovely sheen of fat on the top?

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: bad-to-heat-broth-in-the-microwave?

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.

The only time I use a microwave, ever, is to boil a single cup of water for tea or oatmeal (rare). Since I got an electric kettle, I don't even use it for that. I happily eat cold leftoevers, though. Never understood why people have to have their food piping hot all the time. The only thing really bad when cold is beef fat--yuck!
