Obviously, this approach does not question the historical, political, socio- economic and cultural determinants that determine the type of food produced, nor the factors that shape the dietary habits of communities. It is an approach that ignores power relations, oppression and discrimination. It does not ask who makes the decisions and how the urban or “western” diet was imposed on the whole world, a diet rich in fats, sugars, refined carbohydrates, meat and animal products but low in vegetables, legumes and coarse grains. The increase in consumption of these products is closely linked to the agricultural policies of the world’s major agricultural powers. These policies introduced a series of incentives (production subsidies, public research, export subsidies), which led to a concentration of production on basic cereals (wheat, maize, rice) and oilseeds. On the other hand, the liberalization of trade in agri-food products and fisheries, as well as the promotion of foreign investment in the entire food chain, have played a central role in the expansion of the role of transnational corporations throughout the food chain.
