Walker advocated a diet based solely on raw plants like vegetables, fruits and nuts. He considered cooked, baked or frozen food dead and therefore unhealthy, saying that "while such food can, and does, sustain life in the human system, it does so at the expense of progressively degenerating health, energy, and vitality." As a strict vegan, he did not recommend eating meat, dairy products, fish or eggs. His diet suggestions avoided such staple foods as bread, pasta and rice.
Now, while I think every person is different and therefore, every diet should be different, I do believe that all diets should consist of mainly raw foods.
