Food transitions in history have been fast, violent processes in some
cases, while on other occasions they have taken place slowly,
overlapping the traditional food culture as food items are replaced
by new ones. Despite the contribution of potato and maize to
avoiding famine in Europe, the exclusive crop system caused serious
problems. Main food transitions are currently taking place in Asia.
Emerging economies face the dilemma of improving the health and
well-being of the population while avoiding excess and surplus. The
challenge is twofold: on the one hand, to counteract the negative
effects of food transitions and, on the other, to fight against
hunger and malnutrition.
