Query: Good book

just revisited this book after having read it 20 years (or more) ago, in the original. It is very eye opening. When I first read it at the tender age of 24, I diagnosed myself as hyperinsulinistic, and got off the sugar. That's not an easy trick, considering the culture of family around me that did everything in her power (Mom, who else?) to sabotage my new diet, and play manipulation to make me feel bad for not sharing in the addiction she raised me on. Now, she's 80, and freshly diagnosed diabetic, and refuses to go on Dr's drugs (made her feel bad), so this book is now going to her. It's all related, it's not a separate thing. Also new is high fructose corn syrup, came out after the book, so is not mentioned. Google fructose rats for some eye openers on the creation of diabetes, metabolic syndrome, congestive heart failure, cushing's syndrome and other irritations caused by fructose.
