The significance of industrial processing for the nature of food and the state of human health - and in particular the techniques and ingredients developed by modern food science and technology - is generally underestimated. This is evident in both national and international policies and strategies designed to improve populations' nutrition and health. Until recently it has also been neglected in epidemiological and experimental studies concerning diet, nutrition and health. This report seeks to assess the impact of ultra-processed food on diet quality and health, based on NOVA, a food classification system developed by researchers at the University of Sao Paulo, Brazil.

The increase in the volume of industrially processed products in the global food supply has coincided with an increasing prevalence of obesity and non-communicable diseases in many countries, suggesting that ultra-processed food consumption may be detrimental for human health. However, studies are still limited and underline the need to better understand the main determinants of their consumption and the mechanisms that may explain the associations between these products and human health. This Special Issue collected new studies investigating the relationship between the consumption of ultra-processed foods, diet quality and human health, including those aiming to: Develop new tools to better determine the rate of consumption of ultra-processed foods in the population; Investigate the rate of consumption of ultra-processed foods in different subgroups of the population, including subjects following different dietary patterns; Analyse the relationship between the consumption of ultra-processed foods and markers of health status; Explore possible mechanisms behind associations between the consumption of processed foods and health By providing up-to-date assessments of ultra-processed foods consumption and health implications, these reports will contribute to understanding if future public health nutrition policies are needed.

The NOVA system is a food classification system based on the degree and purpose of industrial food processing. NOVA, which introduced ‘ultra-processed’ as a food category, has been widely employed within the research community, and is increasingly used by national governments, international organisations, and civil society. Ultra-processed foods (UPF) are defined as formulations of food-derived substances (e.g., fats, sugars, starch, protein isolate) that contain little if any whole food and include classes of additives whose function is to make the final product palatable or more appealing (‘cosmetic additives’), like colours, flavours, and emulsifiers. The impact of the production and consumption of ultra-processed foods on human and planetary health has been acknowledged and has started to gather global attention more recently. Because UPFs have become dominant components in diets of populations worldwide, there is an urgent need to scrutinise the human health, sustainability, and food environment impacts across a range of populations and country contexts and to understand the implications of their consumption for health inequalities.

Considering the detrimental environmental impact of current food systems, and the concerns raised about their sustainability, there is an urgent need to promote diets that are healthy and have low environmental impacts. These diets also need to be socio-culturally acceptable and economically accessible for all. Acknowledging the existence of diverging views on the concepts of sustainable diets and healthy diets, countries have requested guidance from the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) on what constitutes sustainable healthy diets. These guiding principles take a holistic approach to diets; they consider international nutrition recommendations; the environmental cost of food production and consumption; and the adaptability to local social, cultural and economic contexts. This publication aims to support the efforts of countries as they work to transform food systems to deliver on sustainable healthy diets, contributing to the achievement of the SDGs at country level, especially Goals 1 (No Poverty), 2 (Zero Hunger), 3 (Good Health and Well-Being), 4 (Quality Education), 5 (Gender Equality) and 12 (Responsible Consumption and Production) and 13 (Climate Action).

Overeating and obesity are on the rise. Despite public health warnings, availability of diet books and programs, and the stigma associated with obesity, many people find it difficult to achieve and maintain a healthy body weight. While there are many books on the topic of caloric or need-based eating, obesity and overeating can also result from eating that is not driven by hunger. Recent research found that excess food intake is largely driven by the palatability of food and the pleasure derived from eating. Hedonic Eating: How the Pleasure of Food Affects Our Brains and Behavior discusses the pleasurable aspects of food intake that may cause and perpetuate overconsumption. Broad in its scope, this book examines the various behavioral, biological, and social rewards of food. The comprehensive chapters cover topics ranging from the neurochemistry of food reward to the hotly debated concept of 'food addiction,' while providing relevant and up-to-date information from the current body of scientific literature regarding food reward.

Reducing the intake of sodium is an important public health goal for Americans. Since the 1970s, an array of public health interventions and national dietary guidelines has sought to reduce sodium intake. However, the U.S. population still consumes more sodium than is recommended, placing individuals at risk for diseases related to elevated blood pressure. Strategies to Reduce Sodium Intake in the United States evaluates and makes recommendations about strategies that could be implemented to reduce dietary sodium intake to levels recommended by the Dietary Guidelines for Americans. The book reviews past and ongoing efforts to reduce the sodium content of the food supply and to motivate consumers to change behavior. Based on past lessons learned, the book makes recommendations for future initiatives. It is an excellent resource for federal and state public health officials, the processed food and food service industries, health care professionals, consumer advocacy groups, and academic researchers.

“Personalised Nutrition” represents any initiative that attempts to provide tailor-made healthy eating advice based on the nutritional needs of each individual, as these are dictated by the individual’s behaviour, phenotype and/or genotype, and their interactions. This Special Issue of Nutrients is dedicated to the development, implementation and assessment of the effectiveness of evidence-based “Personalised Nutrition” strategies. In this regard, a selection of reviews and original research manuscripts will bring together the latest evidence on how lifestyle habits, physiology, nutraceuticals, gut microbiome and genetics can be integrated into nutritional solutions, specific to the needs of each individual, for maintaining health and preventing diseases.

Obesity in childhood and adolescence has reached epidemic proportions in all industrialized countries around the world. Its impact on individual lives as well as on health economics has to be recognized by physicians and the public alike. Among the most common consequences of obesity in the adolescent are hypertension, dyslipidemia, back pain and psychosocial problems. Therapeutic strategies include psychological and family therapy, lifestyle/behavior modification and nutrition education. The role of regular exercise and exercise programs is emphasized. Surgical procedures and drugs used in adult obesity are still not generally recommended for obese adolescents. This book aims to increase physicians knowledge and understanding of obesity in childhood and adolescence as well as to further public awareness of the health burden and economic dimension of obesity at a young age. Several chapters deliver insights into the basic understanding of which factors contribute to or prevent the development of overweight and obesity in young people. Other contributions provide tools for the clinician to manage the care of the child and adolescent with overweight/obesity. In addition, knowledge from the latest scientific studies on the molecular biology of obesity is also presented.

This book outlines a new cognitive-behavioral treatment for patients of all age groups with avoidant/restrictive food intake disorder.
