Abstract

Les acides gras polyinsaturés à longue chaîne peuvent être divisés en deux groupes : les oméga-3 et les oméga-6. Tous les deux sont des acides gras dits « essentiels » car l’organisme n’est pas capable de les synthétiser, ils doivent donc être apportés par le régime alimentaire. Parmi les acides gras oméga-3 importants, on peut citer l’acide alpha-linolénique (ALA), l'acide docosahexaénoïque (DHA) et l'acide eicosapentaénoïque (EPA). Concernant les acides gras oméga-6, j’aborderai l’acide linoléique (LA) et l’acide arachidonique (AA). Les sources alimentaires en acides gras de type oméga-3 sont à la fois animales et végétales. Certains types de poisson (saumon, thon, maquereau, sardine) sont très riches en EPA et DHA contrairement à l’ALA qu’on retrouvera plutôt dans les végétaux. La balance oméga6/oméga-3 est déséquilibrée dans le régime occidental car la nourriture est souvent trop riche en acides oméga-6 et pauvre en acides oméga-3. Les principales sources en acides gras oméga-6 sont le maïs, les huiles de carthame et de tournesol. Ce déséquilibre entre oméga6/oméga-3 aurait un impact négatif sur la santé. Outre l’importance de ce ratio, les quantités sont également importantes à considérer. De nombreuses recherches semblent montrer qu’un apport suffisant en EPA et DHA dans le régime alimentaire permet de prévenir des problèmes, tels que les maladies cardiovasculaires, métaboliques, le cancer et les problèmes inflammatoires. 
A contrario, il apparaît qu’un excès d’acides gras oméga-6 joue un rôle défavorable.

Abstract

The impact of fat intake on hypercholesterolemia and related atherosclerotic cardiovascular diseases has been studied for decades. However, the current evidence base suggests that fatty acids also influences cardiometabolic diseases through other mechanisms including effects on glucose metabolism, body fat distribution, blood pressure, inflammation, and heart rate. Furthermore, studies evaluating single fatty acids have challenged the simplistic view of shared health effects within fatty acid groups categorized by degree of saturation. In addition, investigations of endogenous fatty acid metabolism, including genetic studies of fatty acid metabolizing enzymes, and the identification of novel metabolically derived fatty acids have further increased the complexity of fatty acids’ health impacts. This Special Issue aims to include original research and up-to-date reviews on genetic and dietary modulation of fatty acids, and the role and function of dietary and metabolically derived fatty acids in cardiometabolic health.

Abstract

The role of nutrition in health and disease has been appreciated from time immemorial. Around 400 B.C., Hippocrates wrote “Let food by thy medicine and medicine be thy food.” In the 12th century, the great philosopher and physician Moses Maimonides wrote “any disease that can be treated by diet should be treated by no other means.” Now, in the 21st century, we are bombarded by claims in the media of “superfoods,” wondrous nutritional supplements, and special diets that promise to cure or prevent disease, improve health and restore functioning. Much of the focus has been on neurological disease, brain health and psychological functioning (behavior, cognition, and emotion). The hyperbole aside, there has been considerable progress in the past decade in our understanding of the contribution of specific nutrients and dietary patterns to brain development, physiology, and functioning. This Special Issue of Brain Sciences is devoted to the latest research on the role of nutritional deficiencies and excesses in the genesis of brain dysfunction, and use of diet for the prevention and treatment of brain and mental disorders. Basic laboratory and clinical research studies of the immature, adult, and aged nervous system are all welcome.

Abstract

“Personalised Nutrition” represents any initiative that attempts to provide tailor-made healthy eating advice based on the nutritional needs of each individual, as these are dictated by the individual’s behaviour, phenotype and/or genotype, and their interactions. This Special Issue of Nutrients is dedicated to the development, implementation and assessment of the effectiveness of evidence-based “Personalised Nutrition” strategies. In this regard, a selection of reviews and original research manuscripts will bring together the latest evidence on how lifestyle habits, physiology, nutraceuticals, gut microbiome and genetics can be integrated into nutritional solutions, specific to the needs of each individual, for maintaining health and preventing diseases.

Abstract

Human lactation has evolved to produce a milk composition that is uniquely-designed for the human infant. Not only does human milk optimize infant growth and development, it also provides protection from infection and disease. More recently, the importance of human milk and breastfeeding in the programming of infant health has risen to the fore. Anchoring of infant feeding in the developmental origins of health and disease has led to a resurgence of research focused in this area. Milk composition is highly variable both between and within mothers. Indeed the distinct maternal human milk signature, including its own microbiome, is influenced by environmental factors, such as diet, health, body composition and geographic residence. An understanding of these changes will lead to unravelling the adaptation of milk to the environment and its impact on the infant. In terms of the promotion of breastfeeding, health economics and epidemiology is instrumental in shaping public health policy and identifying barriers to breastfeeding. Further, basic research is imperative in order to design evidence-based interventions to improve both breastfeeding duration and women’s breastfeeding experience.

Abstract

Tissue fibrosis may occur for unknown causes or be the consequence of many pathological conditions including chronic inflammatory or infectious diseases, autoimmune disorders, graft rejection, or malignancy. On the other hand, malignant tumors have been identified in fibrotic tissues decades ago, and now accumulating evidence suggests that fibrotic lesions enhance the risk of cancer in several organs such as liver, lungs, and breast. Disruption of an organ parenchymal cells and of its normal structural scaffold during tissue fibrogenesis appears to induce loss of cell polarity, promoting uncontrolled cell proliferation that may eventually lead to cancer development. Many cellular and molecular abnormalities including aberrant expression of microRNAs, genetic and epigenetic alterations, evasion or delayed apoptosis, unregulated intracellular signal pathways, and dysregulation or defective intercellular communications have been proposed to explain this link between fibrogenesis and carcinogenesis. However, the precise mechanisms of this fibrosis-to-cancer transition remain unclear. This book presents a collection of reviews and original articles summarizing recent advances in understanding the molecular mechanisms of cancer development in fibrotic organs.

Abstract

Acute inflammation is a highly regulated process, and its dysregulation can lead to the development of a chronic inflammatory state which is believed to play a main role in the pathogenesis of many diseases, including cancer. In recent years, the need to find new anti-inflammatory molecules has raised the scientific community´s interest for marine natural products. In this regard, the marine environment represents a source for isolating a wealth of bioactive compounds. In this Special Issue, the reported products have been obtained from microalgae, sea cucumber, octopus, squid, red alga-derived fungus, cnidarians, hard-shelled mussel, and sponges.

Abstract

In pregnancy, maternal nutrition sustains and nourishes the developing child. Imbalances in either the direction of nutritional excess or deficiency can have adverse consequences for child health. In addition, more research now suggests that good pregnancy nutrition influences child health beyond pregnancy and delivery. This includes modifying the risk of child health outcomes as they enter childhood and adulthood through influences on placental development, hormonal pathways, and organ structure and function. Poor pregnancy nutrition may also compromise maternal health during pregnancy, which may have long-term consequences for women’s health. Understanding the biological and social mechanisms operating during pregnancy can help in the design of better clinical and public health interventions. This Special Issue on “The Role of Pregnancy Nutrition in Maternal and Offspring Health” includes etiological and mechanistic studies of pregnancy nutrition with short- and long-term maternal and child health outcomes, including original research, narrative reviews, and systematic reviews and meta-analyses. Together, this body of work provides important insights into the influence of dietary patterns, food groups, and nutrients on pregnancy outcomes, and long-term neurodevelopmental, respiratory, and metabolic health in the children. It also highlights nutritional consequences for specific groups of women, including those with pregnancy complications and eating disorders.
