Le but de cette Ligne directrice est de déterminer les effets d'une substance administrée avec de la nourriture aux oiseaux. Des oiseaux sont alimentés par un régime contenant la substance d'essai à différentes concentrations pendant une période de cinq jours. Deux groupes de contrôle et un groupe de traitement pour chacun des cinq niveaux (au moins) de concentrations alimentaires de la substance d'essai devraient être employés. Chaque groupe se compose de 10 oiseaux. La durée minimum de l'essai est de huit jours : cinq jours d'alimentation avec la substance d'essai, suivis de trois jours d'alimentation normale. Des équipements appropriés pour l’élevage d’oiseaux en local clos sont nécessaires. Ceux-ci incluent des mécanismes de régulation de la température, de l'humidité et de la lumière au besoin, ainsi que des cages de capacité suffisante pour élever des oiseaux. La mortalité et les signes de toxicité sont enregistrés quotidiennement. Les observations suivantes devraient être faites pendant l'essai : des signes d'intoxication et de tout autre comportement anormal, la mortalité, le poids corporels et la consommation de nourriture.

Annotation Diet and lifestyle choices can substantially predispose an individual to, or protect against, many age- and obesity-related chronic diseases. According to the NIH Office of Dietary Supplements, dietary bioactives arecompounds in foodsnot needed for basic human nutrition but responsible for changes in health status. 1 These compounds are safe at normal food consumption levels (e.g., anthocyanins in berries) and their biological activities may come from a single compound (e.g., lutein in spinach) or a class of compounds (e.g., avenanthramides in oats) even if the exact identity and composition are unknown. Bioactive compounds of plants; can vary significantly in their ratios and relative concentrations depending onfactors such as cultivation, soil, altitude, and weather conditions. Substantial scientific evidence is available for some health promoting phytochemicals, such as dose-response relations, for performance and/or reduction in the risk of chronic disease. However, several limitations relating to absorption, distribution, metabolism and excretion of many dietary bioactives still exist and must be better understood This Special Issue compiles recent discoveries that advance our understanding of how dietary bioactive, particularly from fruits and vegetables, influence long-term health maintenance and disease prevention.

We invite you to contribute to a Special Issue of Nutrients, entitled "Dietary Supplements". The purpose of this Special Issue is to advance dietary supplement science by presenting commissioned overviews on four nutrients of particular current interest and controversy: Vitamin D, iodine, iron, and omega-3 fatty acids. To supplement these contributions, we welcome the submission of manuscripts describing original research or providing systematic reviews related to various issues in dietary supplement science. Manuscripts across a broad range of topics will be considered, but we are particularly interested in manuscripts that address the following areas: - Health effects, both positive and negative, of single nutrients, such as vitamin D, iodine, iron, and omega-3 fatty acids, with an emphasis on human studies. - Human clinical trials of dietary supplement use - Motivations for and prevalence of the use of dietary supplements - Mechanisms of action of nutrients and other bioactive components of dietary supplements. - Biomarkers of nutritional status, especially those measured in human samples. - Development and application of analytical tools for the measurement of bioactive components of dietary supplements. - Databases of dietary supplements' composition for use in improving the assessment of nutrient intake and of the exposure to ingredients present in these products in human populations.

Dear Readers, This book describes the ability of some foods or natural substances extracted by plants to counteract some of the most common diseases at present, such as obesity, diabetes, intestinal inflammatory diseases, and neurodegeneration. It is well accepted that high-fat diets that are rich in saturated fats are involved in the onset and progression of obesity and its dangerous comorbidities. It is also well accepted that a balanced diet is useful to maintain a good health status and the choice of certain foods could help to counteract the onset of chronic diseases. Foods and natural substances rich in compounds with anti-inflammatory and antioxidant properties should be paid attention. Most of these foods belong to the Mediterranean Diet, and they are famous for being rich of unsaturated fatty acids, such as the oleic acid found in extra-virgin olive oil, or the omega 3 contained in fish, vitamin D and vitamin C with their high anti-oxidant capacity, and spices and nuts that can counteract inflammatory status. These substances have also anti-obesity properties, because they are able to reduce fat mass and and restore the physiological role of fat tissue. Therefore, strict adherence to this healthy diet could be enough to prevent the onset of chronic diseases linked to fatty diets or aging. The scientific data collected in this book could provide new insights, allowing for readers to change their own dietary habits and make more informed food choices.
