I was reading an article over at Excavating Eden on Three Ways Modern Civilization Neuters You about microwaving food & it reminded me of exactly why I ditched my microwave. I always had an uneasy feeling using it, but didn’t really have anything definite to go on & it is just too convenient to use. I had to go cold turkey.
We got rid of our microwave a year or two ago. I was making a lot of bone broths & the microwave was awesome because you could make the broth, store it in mason jars in the refrigerator & then heat it up as needed in the microwave. Easy peasy. Until I read the bad news in this (very excellent) Weston A.Price article.
Whatever form of gelatin is used, it should never be cooked or reheated in the microwave. According to a letter published in The Lancet, the common practice of microwaving converts l-proline to d-proline. They write, “The conversion of trans to cis forms could be hazardous because when cis-amino acids are incorporated into peptides and proteins instead of their trans isomers, this can lead to structural, functional and immunological changes.” They further note that “d-proline is neurotoxic and we have reported nephrotoxic and heptatotoxic effects of this compound.”55 In other words, the gelatin in homemade broth confers wonderous benefits, but if you heat it in the microwave, it becomes toxic to the liver, kidneys and nervous system. […]There is no reason to think that proline is the only amino subject to this kind of destruction, and it is likely that other aminos would be similarly affected. The studies, however, were done on proline.
So, instead of making an extremely healthful substance I was basically poisoning my household. Yay! Liquid death! Then I looked up what else contains proline & even coffee has it. Basically if there is protein in a food, you should not microwave that food. Our microwave was promptly donated to GoodWill to poison the less fortunate.
A lot of restaurants freeze then microwave their food like Applebee’s does, so this is another reason to do more of your cooking at home.
