Book Description
The growing consumer interest in health and fitness has expanded the market for a wide range of products, from yoga mats to the multiple dietary supplements now on the market. Supplements are popular, but are they safe? Many dietary supplements are probably safe when used as recommended. However, since 1994 when Congress decided that they should be regulated as if they were foods, they are assumed to be safe unless the Food and Drug Administration can demonstrate that they pose a significant risk to the consumer. But there are many types of products that qualify as dietary supplements, and the distinctions can become muddled and vague. Manufacturers are not legally required to provide specific information about safety before marketing their products. And the sales of supplements have been steadily increasingâ€"all together, the various types now bring in almost $16 billion per year. Given these confounding factors, what kind of information can the Food and Drug Administration use to effectively regulate dietary supplements? This book provides a framework for evaluating dietary supplement safety and protecting the health of consumers.

Book Description
From 1982 to 1985, the period on which this book focuses, the Soviet Union was governed by a succession of ailing old men—Brezhnev, Andropov, and Chernenko—who, supported by an equally elderly Politburo, were often physically incapable of controlling and directing the bureaucratic state machine and party organization. This unprecedented situation precipitated a secret and bitter power struggle within the top Soviet leadership between two main factions: the Chernenko apparatchiks, who had risen to power under Brezhnev and owed their positions to him; and the supporters of Andropov, including the younger, more dynamic, and power-hungry members of the party elite, who had been advocating fairly bold reforms to deal with the grave social and economic problems facing the USSR. Dr. Hazan provides a detailed analysis of this hidden power struggle as he examines the final years of Brezhnev's reign and the brief ascendancies of Andropov and Chernenko. These rapid changes led to the demise of the old guard in the Politburo and the emergence of a new breed of leader in Mikhail Gorbachev, culminating in the final consolidation of his power at the 27th CPSU Congress. Drawing on an extensive range of primary sources and using vivid examples of how the factions exploited the gigantic propaganda machine of the Soviet mass media, the author looks behind the Kremlin's walls to explore the essence of Soviet politics. The book describes the power base of each of the recent Soviet leaders and analyzes the steps they took to consolidate their positions and tighten controls over the bureaucracy and the military.

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.
