Breathing, drinking and eating - these are vital needs that every single living being has to pursue in order to survive. But the human species is unique. For it has given nutrition a meaning that is anything but a biological necessity. Mealtime is an important moment of every day and is celebrated with appreciation by all humanity. In the developed world, chefs have become stars, gastronomy an art. Industrially processed foods abound and they are transported all over the world. But such opulence should not hide the fact that for a large part of the world's population, adequate food intake is a daily struggle. In the future, conditions for the food system will continue to change: climate change, dwindling water resources, increasing population growth, the sharp increase in obesity and diabetes will further highlight the contradictions in the current system. For man currently reaches the limits of his nutritional model. How will the nine billion people be nourished by 2050 if forecasts predict a 70 percent increase in the production of agricultural products? Can science and technology provide solutions that respect the planet and all its inhabitants? At the beginning of the 21st century, the nutritional model must be reinvented. But which direction will it take? There is no doubt that humanity faces one of the greatest challenges of the future.
