Microwaving bm

Post by Penguin » Fri Jul 10, 2015 12:23 am

Is there any evidence that microwaving BM actually damages it?

I thought the problem with microwaving bm was only because it heated inconsistently and could burn a baby if you were warming it for them to feed? Says me who doesn't even own a microwave...

Microwaving is thought to damage the "live" stuff in BM - all the antibodies, enzymes and what not. Storage, freezing and conventional warming are going to damage them to some extent too, of course.

Hot spots are probably a bigger problem, unless all the BM your baby drinks is microwaved. I worked in a cafe once where we weren't allowed to microwave baby bottles for customers, but we had a few special tall containers to fill with hot water so parents could warm the bottles at their tables.

I've heard this a lot but has it ever actually been tested? Esp when compared to EBM which has already been frozen and is heated with hot water?

I'm not sure if it has been tested. But I have read that it damages the live stuff more than freezing and heating in hot water. And knowing how a microwave cooks it doesn't surprise me (and I don't mean stuff I learnt off the internet here, I actually mean physics lessons). It also leaves hot spots which are a problem. Of course EBM heated in a microwave and stirred well to prevent hot spots would still be better than formula, because at its base it is human milk not cows milk. So up to you really. Maybe ask the LRC (or whatever it is called these days) they probably would have access to the actual research. And check the references at the bottom of the expressing and storing info on our website.
