“What a great book! This is a nice break from the typical diet genre in that there is not one exact theory to follow. As with most systems in our world,there are many interactions taking place (many of which we are probably not even aware of yet) and there is typically not one single distinct basis for how it operates. Rather, nearly all events that we observe are a complex system of many different factors combined with differing amounts of influence, at differing times, based on even more other auxiliary factors. In, "In Defence of Food", Pollan explains this, and other ideas, in terms of nutritionism more eloquently and succinctly. The research he digs up that others have done is fascinating as well. His purpose being to reiterate the idea that we do not need to focus on a single solution but rather he gives a general diet. That is that we can simply choose to , "Eat food, not too much, mostly plants."”
