One of the things that make me wonder is the idea that there are " diseases if civilisation" (accepted, look at increases in asthma etc) and that they are caused by diet

Of all the things that exist in the modern world, lead in atmosphere, weird fungicides in our furniture fire retardants, etc, why is it the one thing that is under individual control that is the main contributor to our malease - it seems far too linked to the common "if you are ill / poor then you aren't trying hard enough" meme that Oprah et al tend to fall for.

Anyway, as a set of nutritional guidelines it seems reasonable, if only because the avergage food obsessed westerner has aceess to a range of fruit veg and meat that our ancestors never dreamed of.

Now stop trying to persuade me to agree with you so that I can be saved - it smacks of religion
