Calorie Restriction, Aging and Longevity


Book Description

Food or calorie restriction has been shown in many short-lived animals and the rhesus monkey to prolong life-span. Life-long nutrition studies are not possible in humans because of their long survival. Studies over two to six years in healthy adult humans have, however, shown that a 20% reduction in food or calorie intake slows many indices of normal and disease-related aging. Thus, it is widely believed that long-term reduction in calorie or food intake will delay the onset of age-related diseases such as heart disease, diabetes and cancer, and so prolong life. Over the last 20 or more years there has been a progressive rise in food intake in many countries of the world, accompanied by a rising incidence of obesity. Thus our increasing food and calorie intake has been linked to the rising incidence of cardiovascular disease and diabetes in early adult life. It is accepted that overeating, accompanied by reduced physical exercise, will lead to more age-related diseases and shortening of life-span. The answer is to reduce our calorie intake, improve our diet, and exercise more. But calorie restriction is extremely difficult to maintain for long periods. How then can we solve this problem? Edited by a team of highly distinguished academics, this book provides the latest information on the beneficial effects of calorie restriction on health and life-span. This book brings us closer to an understanding at the molecular, cellular and whole organism level of the way forward.




Nutrition and Cancer Prevention


Book Description

Cancer is a major global public health problem. Among different environmental and lifestyle factors contributing to cancer risk, diet is a key one. On the one hand, obesity and increased consumption of red and processed meat, ethanol, sugar and saturated fatty acids are associated with increased cancer risk. On the other hand, consumption of micronutrients such as vitamin D, selenium, zinc, folate and bioactive compounds from fruits and vegetables is associated with decreased risk. Written by an influential, international team of experts, this book presents and discusses current topics on nutrition and cancer prevention. It covers both nutritional influences on different cancers plus specific chapters on the commonly occurring cancers. Nutritional genomics-based studies show that some dietary components modulate carcinogenesis through complex cellular and molecular mechanisms. A better understanding of these different cellular and molecular mechanisms is needed to establish efficient dietary recommendations for cancer prevention. This book will provide such an understanding, serving as an important book for all those working in nutritional health, food science and cancer research.




Nutrition, Food and Diet in Ageing and Longevity


Book Description

This edited volume is a compilation of 30 articles discussing what constitutes food for health and longevity. The aim is to provide up-to-date information, insights, and future tendencies in the ongoing scientific research about nutritional components, food habits and dietary patterns in different cultures. The health-sustaining and health-promoting effects of food are certainly founded in its overall composition of macronutrients and micronutrients. However, the consumption of these nutrients is normally in the form of raw or prepared food from the animal and plant sources. The book is divided into four parts and a conclusion, and successfully convenes the well-established information and knowledge, along with the personal views of a diversified group of researchers and academicians on the multifaceted aspects of nutrition, food and diet. The first part reviews the scientific information about proteins, carbohydrates, fats and oils, micronutrients, pro- and pre-biotics, and hormetins, along with a discussion of the evolutionary principles and constraints about what is optimal food, if any. The second part discusses various kinds of foods and food supplements with respect to their claimed benefits for general health and prevention of some diseases. The third part brings in the cultural aspects, such as what are the principles of healthy eating according to the traditional Chinese and Indian systems, what is the importance of mealing times and daily rhythms, and how different cultures have developed different folk wisdoms for eating for health, longevity and immortality. In the part four, various approaches which are either already in practice or are still in the testing and research phases are discussed and evaluated critically, for example intermittent fasting and calorie restriction, food-based short peptides, senolytics, Ayurvedic compounds, optimal food for old people, and food for the prevention of obesity and other metabolic disorders. The overreaching aim of this book is to inform, inspire and encourage students, researchers, educators and medical health professionals thinking about food and food habits in a holistic context of our habits, cultures and patterns. Food cannot be reduced to a pill of nutritional components. Eating food is a complex human behavior culturally evolved over thousands of years. Perhaps the old adage “we are what we eat” needs to be modified to “we eat what we are”.




The Effect of Calorie Restriction and Intermittent Fasting on Health and Disease


Book Description

Recent biochemical studies indicate that calorie restriction (CR) is a widely accepted method for anti-aging intervention. CR and intermittent fasting (IF), which involves reduced calories but proper nutritional intake during specific periods, are interventions that can consistently promote health benefits, delay biological aging, and extend both average and maximal lifespan. Furthermore, CR can modulate age-related diseases such as Alzheimer’s disease, atherosclerosis, diabetes, obesity, cancer, and others. Advances in omics technologies have provided a technical breakthrough that enabled the investigation of DNA, RNA, proteins, and other cellular molecules and their comprehensive interactions in a biological context. Nowadays, it is possible to analyze and integrate biological processes that occur in aging systems at the molecular level using state-of-the-art techniques such as next-generation sequencing (NGS), proteomics, lipidomics, metabolomics, and epigenomics. Omics technology and systems gerontology provide predictive information on CR effects, molecular mechanisms, and pathways underlying the anti-aging actions of CR and IF. This Special Issue, “The effects of calorie restriction and intermittent fasting on health and disease”, focuses on the effects of calorie restriction and intermittent fasting on age-related inflammation, autophagy, metabolism, longevity, mitochondrial function, and age-related diseases.
