Sometime back, I posted a lengthy note on diabetes and some pointers to the sources from where I got the information in the hope that it'll help those suffering from diabetes. One reader, called Ahamed Nadeem (I don't know who he is) pointed out that some information and sources are incorrect. I double checked the validity of the sources and found that he was indeed correct. I removed that post from the blog. I should be very careful in writing about sensitive things like health. Many thanks to Nadeem.
