I have always kept up with the latest medical studies. Have you seen the one that recently was reported on MSNBC about the findings that "oh, no...it looks like we were wrong...too much insulin production DOES seem to cause heart problems and cancer..." (I took liberty with that quote).
And, honey, that means all this disease we have is being caused by our freely available carb sources. We weren't meant to have constant, steady supplies of simple carbohydrates.
To make it short, from what I have read of your entries, it looks like your interested in finding....what?!
Let me give you this example of why the so-called good, eatin', low fat, moderate diet doesn't work. My ex-boss. He ate healthfully his whole life, he has exercised his whole life, he has never smoked or tried any kind of drugs, he has only drink an occasional glass of wine. He has a close-knit family, goes to bed a reasonable time, takes vacations, etc. etc. Everything that everyone is telling you is healthy....last year he was diagnosed with cancer. A very ferrocious kind. Now that was a confused man. And why shouldn't he be.
So, you see, for all you want of "studies" and "proof"...it isn't worth the paper its written on. As my Mom used to say: "the proof is in the puddin'"
There is no one, right answer. There is only the answer that is right for you. And for a lot of us, eating just normal portions of bread, chips, beer, potatoes, corn, beans etc. doesn't work. It is real obvious when you look at my husband and I. If wee both eat the same foods (except he eats cookies all day), I am overweight and he is not. If he eats the meats I like, his cholesterol would go up. I could go on and on, but the emphasis is: the medical community has long been trying to treat everyone as the same...and we are not.
