My mother has been reading this;

Perfect Health Diet - A diet for healing chronic disease, restoring youthful vitality, and achieving long life | Perfect Health Diet

She's asking lots of questions, but I haven't had time to read it yet! Have you read it? What do you think?

It appears to suggest an awful lot more carbohydrate that what I thought was healthy. However, I am aware that a lot of paleolithic cultures ingest a lot of cassava etc (eg Papua New Guineans tribesmen).
