Hello first

Well, I accidently found a site saying something about eyes where you can see the white of the eye under the iris and that's called Sanpaku eyes and indicates bad mental or physical health and was mention by George Ohsawa in a book called "You are all Sanpaku". He says that ppl with Sanpuku eyes are proned to accidents and such because they're out of balance with nature and the universe and such.He added that a macrobiotic diet would be a solution for this.
Anyone know how much truth there is to this? To tell the truth,I laughed when I read this because my eyes apparently have been Sanpuku since I was a baby and my friends first pointed it out in elementary school(ppl either said it made me look hypnotic or sleepy) long before I started drinking coffee or staying up late to study or such and since then this appearance has neither decreased nor increased.
Any thoughts?
