I do not recall reading anything about being positive or negative, but I didn't read the book real thorughly (it is quite large).

The naturalist that my friend went to was connected with a health food store. She uses saliva and other things to figure out what was going on. I don't know if I believe in all this, but I will say this, something in whatever she tested (which was not blood) showed her that my friend has high cholesterol. And she does...extremely high. So...

If I knew at your age what I know now, the one thing I would do regardless of what "diet" I was on or anything else going on, I would avoid processed white flour like the plague. I wonder at times if I had known and done this one thing if I would have ever had a weight problem!
