**Preface to "Sustainability in Food Consumption and Food Security"**

The transformation of food chains towards sustainability in food consumption and food security is a global issue, connected with the global challenges of poverty reduction, employment and urbanization. Combating malnutrition—undernutrition and micronutrient deficiencies—as well as overweight and obesity is an increasing problem. Research can find sustainable solutions to challenges facing the global and national food systems relating to sustainable food consumption and food security. The integrative food systems approach encompasses all of the steps involved, from growing through to processing, transporting, trading, purchasing, consuming food, and disposing of or recycling food waste. Sustainability related to product standards and reactions of consumers to these standards are also of grea<sup>t</sup> importance.

This book discusses opportunities for and challenges to sustainable food systems from a food consumption and food security perspective by promoting healthy diets and increasing the focus on nutrition, with multiple implications for diet quality and vulnerable groups, reducing food loss and waste, agricultural transformation in the face of increasing competition for land use, responding to climate change and other environmental and social change, and introducing the bioeconomy concept to reduce the environmental impact of food production.
