what do you think of this?
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.Another study suggested that the l-configuration and the proper molecular size are both essential for beneficial effects of l-proline upon memory and for the prevention of depression. 56 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.

54. Pottenger. 55 Lubec, G, et al. Amino acid isomerisation and microwave exposure, Lancet, 1989, 2, 8676, 1392-1393.I know its not chemical toxicity, but I haven't been able to find any other studies confirming or negating this.(and when I last looked that year was only half online..so that paper wasn't available.. must look again sometime:)
In the meantime.. I get these phases where I decide to avoid the microwave.. but they don't last long..Jan
