Lo scopo del libro è di divulgare in modo sintetico e accessibile i risultati degli studi più rigorosi e oggettivi sugli integratori vitaminici e minerali. Il libro offre le risposte alle seguenti domande: • Perché gli integratori sono venduti e vitamine e minerali aggiunti agli alimenti? • L'aggiunta di vitamine e minerali ad un alimento assicura che sia sano? • Si ha lo stesso effetto sulla salute su chi assume vitamine e minerali sotto forma di integratori come dagli alimenti? • Gli integratori vitaminici e minerali sono in grado di prevenire o curare alcune malattie? • L'assunzione di integratori di determinate vitamine e minerali ci aiuta ad invecchiare più lentamente, ad avere più energia o a ridurre l'ansia, lo stress, l'affaticamento o il dolore? • Chi ha bisogno di assumere integratori e perché? • Quali integratori funzionano davvero e quali benefici forniscono? • Può essere pericoloso assumere determinati supplementi di vitamine e minerali? GUIDA PER DIFFERENZIARE LA VERITÀ (BASATA SUI FATTI) E LA MENZOGNA (BASATA SUI MITI E INTERESSI COMMERCIALI). Abbiamo bisogno di integratori alimentari? Aumentano il nostro benessere? Aiutano a prevenire le malattie? Possiamo fidarci di ciò che la pubblicità ci dice? Una buona parte dell'industria degli integratori, supportata dagli amanti della pseudoscienza, esagera i benefici di alcuni prodotti, distorce i risultati o semplicemente li nasconde quando non sono molto promettenti. Ciò rende molto difficile separare informazioni affidabili —basate su fatti – dal marketing pseudocientífico, pseudoscientifico, che mira a vendere. Per questo devi rivolgerti alla scienza. Questo libro offre al lettore una visione realistica basata sulle ultime prove scientifiche; e lo fa da una posizione neutrale, dal momento che l'autore non ha conflitti di interesse. PER PRENDERE LE DECISIONI GIUSTE, È NECESSARIO CONOSCERE LE RISPOSTE A QUESTE DOMANDE: • L'assunzione di integratori di determinate vitamine e minerali ci aiuta ad invecchiare più lentamente, ad avere più energia o/a ridurre l'ansia o il dolore? • Quali integratori funzionano davvero e quali benefici forniscono? • Gli effetti sulla salute delle vitamine e dei minerali nel cibo sono uguali a quelli dei cocktail vitaminici e minerali? • Possiamo mettere a rischio la nostra salute prendendo alcuni integratori QUESTO È CIÒ CHE TROVERAI NEL LIBRO ALIMENTI ARRICCHITI E POTENZIATI CON VITAMINI E MINERALI • I tempi cambiano. cercando di sostiture quello che è perduto LA VENDITA NUMEROSA DI INTEGRATORI DI VITAMINE E MINERALI • Cosa sono gli integratori e chi li consumano? • Perché si vendono gli integratori e si arricchiscono gli alimenti? • Cosa dicono degli integratori i venditori LE PERSONE CHE ASSUMONO INTEGRATORI HANNO UNA SALUTE MIGLIORE? • Come sappiamo quello che sappiamo • Cosa dicono gli studi? • Esiste un integratore in grado di compensare stili di vita non salutari? INTEGRATORI O ALIMENTI? • È meglio ottenere micronutrienti dal cibo • Abbiamo bisogno di una scorta extra di alcuni micronutrienti sotto forma di integratore? IN QUALI CASI I SUPPLEMENTI DI VITAMINE E MINERALI POTREBBERO ESSERE UTILI? • Persone con maggiori esigenze di micronutrienti • Un integratore che funziona • Supplementi promettenti, ma con effetti non ancora provati ATTENZIONE AL MARKETING INGANNEVOLE • Negli Stati Uniti, l'industria si controlla da sola • Dichiarazioni sulla salute: dichiarazioni di marketing o scienza? • L'argomento costo è valido? • È vero che i frutti e le verdure di oggi non sono così nutrienti come quelli di altri tempi? • Test genetici: benvenuta alla nutrizione personalizzata • Perché consumiamo così tanti integratori? DI PIU’ NON E’ MEGLIO • Svantaggi e rischi legati all'assunzion di determinati supplementi • Tossicità ad alte dosi • Bibite «energetiche» • Cosa ha mostrato l'analisi di alcuni integratori?

Ensayo que trata temas ligados al evolucionismo, en relación con el cual se prodigan prejuicios e imprecisiones, como, por ejemplo, la idea de que los términos “evolucionismo” y “darwinismo” son sinónimos. Las teorías evolucionistas son en realidad múltiples. El autor considera en la obra tanto las argumentaciones del evolucionismo como las del creacionismo, las del cual, fuera de ciertos círculos fundamentalistas, no consisten en referencias bíblicas sino que ponen en juego consideraciones racionales. Ensayo que trata temas ligados al evolucionismo, en relación con el cual se prodigan prejuicios e imprecisiones, como, por ejemplo, la idea de que los términos “evolucionismo” y “darwinismo” son sinónimos. Las teorías evolucionistas son en realidad múltiples. En el ensayo, el autor habla, entre otras cosas, del significado del término “caso”, hace ver que la base de la investigación científica es siempre una postura filosófica y a veces también teológica o incluso visceralmente ideológica. Considera los argumentos del creacionismo que, fuera de ciertos círculos fundamentalistas, no consisten en referencias bíblicas sino que ponen en juego consideraciones racionales. Volviendo al evolucionismo, habla de la teoría del equilibrio puntuado, combatida aparentemente por los creacionistas y vista sin embargo con simpatía por los evolucionistas, creyentes o no. Presenta la opinión sobre la evolución de los últimos papas. He aquí algunas opiniones sobre esta obra: Extracto de la justificación de la Mención Especial del Jurado otorgada al ensayo en el 7º Premio Nacional de Artes Literarias Ciudad de Turín: “Un profundo y concreto tratado antropológico, filosófico y religioso que no puede pasar inadvertido, por su competencia concreta y la argumentación particular digna de un tratado universitario merecedor de impresión”. Extracto de la recensión de Elettra Bianchi en la revista Talento 2/2011: “Guido Pagliarino afronta una vez más un argumento de gran importancia y actualidad en el plano del pensamiento, pero también de enorme vastedad y complejidad ya que abarca diversas disciplinas del sector científico, filosófico, religioso e histórico. (…) Después de haber investigado durante años los resultados de las teorías científicas y filosóficas más organizadas y coherentes, Pagliarino reconoce tres expresiones fundamentales: evolucionismo teísta, darwinismo causalista y creacionismo. (…) Se dedica también una gran atención a los escritos filosóficos y religiosos (…) empezando por el Antiguo y el Nuevo Testamento (…) hasta los teólogos más recientes y discutidos como Bergson, Teilhard de Chardin y Rahner y las encíclicas de varios papas, pero también se tocan otros frentes religiosos como el Corán”. Extracto de la recensión de Wilma Minotti Cerini en Literary 7/2011 (http://www.literary.it/dati/literary/m/minotti_cerini/creazione_ed_evoluzione.html): “Para el autor, (…) la alegoría de la historia de la creación de Adán en el Jardín del Edén, modelado por las manos de Dios dando forma al barro e introduciendo dentro de su forma el hálito divino (la Ruah); (…) ¿Dios ha decidido (…) que Adán (…) viniera de una evolución (…)? Si es así, ¿desde qué momento se puede hablar de un Homo Sapiens Sapiens verdadero y real? (…) Esta obra (…) responde exhaustivamente (…). Pasando por encima de otros muchos conceptos, señalo algo que me parece particularmente importante, cuando se afirma que el amor activo frente a lo que se encuentra es lo primero de todo y (…) la caridad precede en importancia a la misma fe, como ya escribía San Paolo; por la proclamación Lumen Gentium del Concilio Vaticano II, todos los hombres caritativos se salvan aunque sean ateos”. Extracto de la recensión de Elisabetta Amistà en SoloLibri (http://www.sololibri.net/Creazione-ed-evoluzione-Guido.html): “Es verdad que las teorías darwinistas han dado lugar a innumerables debates y estudios y asimismo que han influido también negativamente en diversas corrientes de pensamiento, baste citar la locura del darwinismo social. La capacidad de conocer el desarrollo que tuvieron los estudios del científico inglés y la contraposición con el credo de representantes de las diversas realidades religiosas es una tarea ardua, ante la cual Guido Pagliarino no se arredra, usando una escritura clara y de fácil comprensión. La clave de lectura de Creación y evolución es la delicada relación que instaura entre los representantes de la ciencia y los de las fes religiosas y la de los descubrimientos sobr

This book is dedicated to the application of the different theoretical models described in Volume 1 to identify the near-, mid- and far-infrared spectra of linear and nonlinear triatomic molecules in gaseous phase or subjected to environmental constraints, useful for the study of environmental sciences, planetology and astrophysics. The Van Vleck contact transformation method, described in Volume 1, is applied in the calculation and analysis of IR transitions between vibration–rotation energy levels. The extended Lakhlifi–Dahoo substitution model is used in the framework of Liouville’s formalism and the line profiles of triatomic molecules and their isotopologues subjected to environmental constraints are calculated by applying the cumulant expansion. The applications presented in this book show how interactions at the molecular level modify the infrared spectra of triatomics trapped in a nano-cage (substitution site of a rare gas matrix, clathrate, fullerene, zeolite) or adsorbed on a surface, and how these interactions may be used to identify the characteristics of the perturbing environment.
