This volume presents information regarding the mechanisms of protein absorption under normal and pathologic conditions, in addition to reviewing changes that occur at various stages of life. General modifiers of intestinal absorption, such as the processing of foods, the nutritional status of the individual, and disease, are explored with reference to both proteins and minerals. Inorganic macronutrients, namely calcium, magnesium and phosphorus, are discussed in relation to protein ingestion. The book also explores the concept of essential trace elements (e.g., iron, zinc, copper, and iodine) and their link to protein sufficiency. The relationship of ultratrace elements with the content of proteins in food is examined, and the book offers a fresh view of the role of certain elements, particularly zinc, on the conformation of proteins linked to DNA, hormone receptors, and gene products. Protein Nutrition and Mineral Absorption is packed with 2,300 references, 100 figures and graphs, plus 25 tables. Nutritionists and physicians will find this book to be an invaluable reference source for rationalizing nutritional interventions and diet modifications for their patients.
