The subtitle of this book “Get Fit with Foods that Don’t Fight” announces its promotion of a rather offbeat dietary regime known as the Hay System. Rather than analyse one’s menus to be sure one is including a variety of nutrients (such as complementary proteins), this system advises against certain food combinations.
In particular, the aim is to avoid protein and starch at the same meal. So the recipes are slotted into categories for a protein meal and categories for a carbohydrate meal.
I am not too concerned with the theory. I just enjoy the recipes.
