As Barry Sears says, in reality, from the bodily response viewpoint, the consequences of the consumption of such foods are very similar to what would happen if one were to eat, a cup of normal cooking sugar within the space of a few minutes; no dietician would ever recommend that you eat such a quantity of sugar at any one time, yet some still insist on recommending large helpings of rice, pasta and potatoes!
There is another error in that food pyramid in relation to fats: it maintains that all are bad for you, while, in fact, some of them are very useful for our bodies. Extra virgin olive oil, for example, is an enormous gift from nature. The omega-3 family of fatty acids is fundamental for our wellbeing. The fats originating from oily fruits, such as almonds, pine nuts, walnuts and hazelnuts, are also good for you. In short, from now on, you should no longer refer to the 1991 food pyramid, but to the new EnerZona pyramid.
