Book Description
The third and final volume in a series of reports stemming from a multi-national study on breast-feeding (see also Contemporary Patterns of Breast-feeding and The Quantity and Quality of Breast Milk). Responding to inconsistencies in the published data on concentrations of trace elements in breast milk, the study analyzes milk samples collected from women in Guatemala, Hungary, Nigeria, the Philippines, Sweden and Zaire in an effort to obtain reliable data on the quantities of minor and trace elements present in breast milk. The study was also designed to determine whether the concentrations of these elements varied significantly with the socioeconomic group, geographical origin, or nutritional status of the mothers. The book opens with a brief explanation of the biochemical functions of trace elements and the association of deficiencies with various disorders of growth and development. The second chapter explains the careful design of the study, which used standardized procedures for the collection of samples, a single reference analytical laboratory for each element, and appropriate analytical reference materials. Results are then presented for total dry matter and for antimony, arsenic, cadmium, calcium, chlorine, chromium, cobalt, copper, fluorine, iodine, iron, lead, magnesium, manganese, mercury, molybdenum, nickel, phosphorus, potassium, selenium, sodium, tin, vanadium, and zinc. For each element, information is given on any observed differences between study areas, variations in samples between urban and rural areas, and variations in concentrations according to time of year. A discussion of findings compares results of the study with data from the literature, assesses sources of variation in the elemental composition of human milk, and compares the observed daily intake of minor and trace elements with recommended intake. The book concludes that when minor and trace elements are determined under similar conditions in the breast milk of groups of mothers living in different parts of the world, environmental conditions play a major role in determining concentrations. Findings from the study should also prove useful in the formulation of recommendations regarding levels of trace elements in the diet of infants.

Book Description
Human breast milk is considered to be the perfect food for infants, specifically adapted to their needs. Before birth, the mother transfers all the nutrients and bioactive components to the fetus through the placenta. After birth, these substances have to be transferred through colostrum and milk. In particular, human breast milk is supposed to provide all the essential trace elements that are required by the normal term newborn infant. Therefore, the composition of human breast milk and its changes during lactation is a topic of major importance and has been the subject for intensive research. Conversely, human milk can also be a transfer medium of undesirable (toxic) elements from the mother to the infant. An extensive review of the most recent literature was carried out focusing on the current trace elements levels and their changes during lactation. For several elements, there is a consistent knowledge of their characteristic concentrations throughout the various stages of lactation, their dependence on maternal nutritional status, inter-individual and geographical variability, metabolic pathways, inter-elemental relationships, and effects on child development. For many other elements, this knowledge does not exist or is quite limited.

Book Description
As essential nutrients, sodium and potassium contribute to the fundamentals of physiology and pathology of human health and disease. In clinical settings, these are two important blood electrolytes, are frequently measured and influence care decisions. Yet, blood electrolyte concentrations are usually not influenced by dietary intake, as kidney and hormone systems carefully regulate blood values. Over the years, increasing evidence suggests that sodium and potassium intake patterns of children and adults influence long-term population health mostly through complex relationships among dietary intake, blood pressure and cardiovascular health. The public health importance of understanding these relationships, based upon the best available evidence and establishing recommendations to support the development of population clinical practice guidelines and medical care of patients is clear. This report reviews evidence on the relationship between sodium and potassium intakes and indicators of adequacy, toxicity, and chronic disease. It updates the Dietary Reference Intakes (DRIs) using an expanded DRI model that includes consideration of chronic disease endpoints, and outlines research gaps to address the uncertainties identified in the process of deriving the reference values and evaluating public health implications.

Book Description
Now in its second edition, Drugs and Human Lactation is a comprehensive guide to the content and consequences of xenobiotics and micronutrients in human milk, and remains by far the most thorough and extensive work available on this subject. The excellent methodology used for the compilation of the 1st edition has been retained. It begins with an outline of the processes by which substances enter milk during its formation, the effects of drugs on the milk production process, the main determinants of drug excretion into milk and their disposition in the child. There follows an analysis of current data on 234 individual drugs, describing the extent of their passage into human milk, and assessing the risk to the suckling infant. Vitamins and essential trace elements, and radiopharmaceuticals are similarly reviewed. Also included is an account of the factors that influence the passage of environmental and occupational chemicals into milk. The result is a complete overview of what is known and proven, with clear pointers to matters which require further study, and brings the various subject areas up to date. Risks, uncertainties and false alarms which exist have been defined in such a way that they can be avoided. Once again, Drugs and Human Lactation provides a comprehensive guide to the content and consequences of substances in milk. The volume will provide a rational basis for making therapeutic decisions in women who seek to breast-feed. Reproductive Immunology on the first edition: ...a superbly written compendium of reliable information and sensible conclusions and recommendations.

Book Description
Infant formulas are unique because they are the only source of nutrition for many infants during the first 4 to 6 months of life. They are critical to infant health since they must safely support growth and development during a period when the consequences on inadequate nutrition are most severe. Existing guidelines and regulations for evaluating the safety of conventional food ingredients (e.g., vitamins and minerals) added to infant formulas have worked well in the past; however they are not sufficient to address the diversity of potential new ingredients proposed by manufacturers to develop formulas that mimic the perceived and potential benefits of human milk. This book, prepared at the request of the Food and Drug Administration (FDA) and Health Canada, addresses the regulatory and research issues that are critical in assessing the safety of the addition of new ingredients to infants.

Book Description
This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.
