Lecture in the module "Global Food Policies" of the Master in Food, Law and Finance (IUC Torino, 23 Feb 2017). Several very common food policies often implemented in countries of the Global South are presented and analysed through a critical approach (who wins/who loses, balance of power, visible outputs VS underlying causes, collateral effects, paternalism VS universalism, rights-based or needs-based). taxing unhealthy ultra-processed food and beverages (Mexico soda tax as case study), conditional cash transfers and their impact in stunting (Mexico and Brazil as case studies) and patented technologies to save lives VS public research (Plumpy Nut, ready-to-use therapeutic food to save lives in humanitarian situations). The idea is to understand the advantages, impacts and challenges of those well-known food policies.
