The world's leading expert on vitamin D reveals the missing link to achieving optimal health Vitamin D deficiency is the most common medical condition in the world. In America alone, over 200 million people lack sufficient levels of vitamin D and may consequently suffer from chronic health conditions, ranging from daily annoyances like fatigue and pain to life-threatening illnesses such as diabetes, heart disease, and cancer. But few people know why vitamin D is so important and what they can do to avoid the myriad ailments associated with deficiency, including heart disease, cancer, and osteoporosis. There is no better person to demystify this vitamin and showcase its place in human health than author Michael F. Holick, M.D., Ph.D.-the father of modern vitamin D research. With more than three decades spent studying the relationship between vitamin D, limited sun exposure, and human well-being, Dr. Holick shares his findings on how combining the natural curative properties of the sun along with small lifestyle changes can help everyone to live a substantially healthier life. Armed with a three-step plan incorporating safe amounts of sun exposure, the right supplementation, and eating foods rich in vitamin D, Dr. Holick provides prescriptive advice for anyone- from relatively healthy people to those suffering from chronic or even fatal diseases- on how to easily rebuild and maintain optimal levels of this essential hormone. Rich with anecdotes and entertaining case studies, The Vitamin D Solution also presents research from around the world to serve as a wake-up call on this potentially lifesaving hormone for health.

The Nutrition and Health series of books has as an overriding mission to provide health professionals with texts that are considered essential because each includes: a synthesis of the state of the science; timely, in-depth reviews by the leading researchers in their respective fields; extensive, up-to-date fully annotated reference lists; a detailed index; relevant tables and figures; identification of paradigm shifts and the consequences; of information between chapters, but targeted, inter-chapter refer virtually no overlap rals, suggestions of areas for future research; and balanced, data-driven answers to patient questions that are based on the totality of evidence rather than the findings of any single study. The series volumes are not the outcome of a symposium. Rather, each editor has the potential to examine a chosen area with a broad perspective, both in subject matter as well as in the choice of chapter authors. The international perspective, especially with regard to public health initiatives, is emphasized where appropriate. The editors, whose training is both research and practice oriented, have the opportunity to develop a primary objective for their book, define the scope and focus, and then invite the leading authori ties from around the world to be part of their initiative. The authors are encouraged to provide an overview of the field, discuss their own research, and relate the research de findings to potential human health consequences.
Within the last few years, knowledge about vitamins has increased dramatically, resulting in improved understanding of human requirements for many vitamins. This new edition of a bestseller presents comprehensive summaries that analyze the chemical, physiological, and nutritional relationships, as well as highlight newly identified functions, for all recognized vitamins. These include vitamins A, D, K, E, B6, B12, niacin, riboflavin, thiamine, pantothenic acid, biotin, folate, choline, and ascorbic acid. Keeping the tradition of the previous volumes, the Handbook of Vitamins, Fifth Edition provides an updated, contemporary perspective on vitamins in human nutrition. Bringing together leading experts in molecular biology, biochemistry, and physiology, the book contains substantial revisions in every chapter, covering vitamin metabolism, including human requirements, clinical aspects of deficiency, vitamin-dependant cell signals and gene regulation, and roles as coenzymes. The chapter on epigenetics has been updated and expanded to include novel findings about vitamins not previously considered in studies of nutrient-dependent epigenome modification. The book also contains a new chapter on genome stability, highlighting current understanding of vitamin–genome interactions in the evolution of the human genome and the functional consequences of human genetic variation. Maintaining its status as a high-quality reference, this handbook incorporates new discoveries into an updated and revised fifth edition.
Every country in the world is concerned with the nutritional status of its population and in utilizing its natural food resources in the most effective way possible. Surveys based on food intakes and food compositional data are being conducted with the object of establishing recommended intakes of vitamins. These recommendations are constantly being changed as new knowledge comes to light. Analytical techniques using physicochemical and microbiological methods have been largely developed to determine the total vitamin content of a food commodity or diet using the most rigorous extraction method commensurate with the stability of the vitamin. The extraction procedures frequently involve prolonged heating of suitably prepared food samples at extremes of pH to liberate vitamins from chemically bound forms in the food matrix or to remove a preponderance of fat from fatty foods. For several vitamins the data obtained by these means grossly overestimate the nutritional value of the food because the human digestive system fails to liberate bound vitamin forms for subsequent absorption by the intestine. This statement is borne out by reports of vitamin deficiency in situations where the dietary supply of vitamin is adequate on the basis of conventional analysis. Various research labora tories are directing their effort toward the estimation of bioavailable vitamin, i. e. the proportion of vitamin in the food which is available for utilization by the body. So far, few data have been published and there are many gaps in the knowledge required to interpret experimental results.

Popularized by Michael Pollan in his best-selling In Defense of Food, Gyorgy Scrinis's concept of nutritionism refers to the reductive understanding of nutrients as the key indicators of healthy food—an approach that has dominated nutrition science, dietary advice, and food marketing. Scrinis argues this ideology has narrowed and in some cases distorted our appreciation of food quality, such that even highly processed foods may be perceived as healthful depending on their content of "good" or "bad" nutrients. Investigating the butter versus margarine debate, the battle between low-fat, low-carb, and other weight-loss diets, and the food industry's strategic promotion of nutritionally enhanced foods, Scrinis reveals the scientific, social, and economic factors driving our modern fascination with nutrition. Scrinis develops an original framework and terminology for analyzing the characteristics and consequences of nutritionism since the late nineteenth century. He begins with the era of quantification, in which the idea of protective nutrients, caloric reductionism, and vitamins' curative effects took shape. He follows with the era of good and bad nutritionism, which set nutricentric dietary guidelines and defined the parameters of unhealthy nutrients; and concludes with our current era of functional nutritionism, in which the focus has shifted to targeted nutrients, superfoods, and optimal diets. Scrinis's research underscores the critical role of nutrition science and dietary advice in shaping our relationship to food and our bodies and in heightening our nutritional anxieties. He ultimately shows how nutritionism has aligned the demands and perceived needs of consumers with the commercial interests of food manufacturers and corporations. Scrinis also offers an alternative paradigm for assessing the healthfulness of foods—the food quality paradigm—that privileges food production and processing quality, cultural-traditional knowledge, and sensual-practical experience, and promotes less reductive forms of nutrition research and dietary advice.
