Food consumption is influenced by a series of issues that affect both individuals, and people and cultures of the different parts of the world. It studies biosocial risks that have dramatic implications: obesity, anorexia and bulimia; malnutrition and hunger, involving more than 800 million people; the waste food, a real paradox of the global world; the land grabbing. These are very different problems because of causes and dynamics, but all of them require a profound change to be affected: a greater awareness of eating behaviour, an educational action on food topics, an intervention of regulatory institutions, local and international, which guarantees a fair market for products and food sovereignty.
