Does anybody know of any studies linking nutrition and happiness, happiness
not being the absence of depression. My feeling from the reading I've done
recently is that not only are traditional/stone age peoples not prone to
depression, they are also much happier than we are. I have observed this
personally in my travels in Africa. Is there any objective measure of
happiness? And why, for example, are Down's syndrome sufferers always happy?
Is this anything to do with vitamin E levels? pituitary gland?

I bring this up because I have heard that depression is predicted to be the
major illness of western man in the next 20 years, and I've suffered and been
treated for this myself.. My personal feeling is that this is nutrition
linked, and that the steady deterioration of the nutrient level of our food
supply is behind this.
