          Abstract

          Resumen Durante los últimos años se ha incrementado la incidencia de casos de sobrepeso/obesidad entre la población, afectando en ciertas partes del mundo a más de la mitad de la población adulta. La obesidad lleva asociada comorbilidades como la diabetes tipo 2, la esteatosis hepática no alcohólica y las enfermedades cardiovasculares entre otras muchas, que la han convertido en la segunda causa de muerte evitable en el mundo, solo por detrás del tabaquismo. Ante esta nueva realidad se hace necesaria la búsqueda de nuevas estrategias para combatir el sobrepeso/obesidad y sus patologías asociadas. Los nutracéuticos o suplementos dietéticos se han convertido en una herramienta dietética de sumo interés gracias a su contenido en compuestos bioactivos beneficiosos para la salud. De entre estos compuestos bioactivos, este estudio abordará en profundidad dos de ellos: una fibra soluble, los β-glucanos procedentes de la avena, y un tipo de compuesto fenólico, los hidroxicinamatos. Ambos tipos de compuestos presentan efectos complejos y multifactoriales al actuar como agentes hipolipemiantes, hipoglucemiantes, antioxidantes, prebióticos o saciantes. Ejercen su efecto modulando diferentes vías metabólicas que afectan tanto a la absorción como al metabolismo de los lípidos y los glúcidos, reduciendo el daño oxidativo, promoviendo la proliferación de especies bacterianas beneficiosas y reduciendo la ingesta dietética. Se puede concluir que tanto los beta-glucanos como los hidroxicinamatos presentan potencial como herramienta nutricional en el manejo de distintas disfunciones metabólicas asociadas a la obesidad.

          Translated abstract

          Abstract Over the last few years the prevalence of overweight and obesity has increased, affecting in certain parts of the World to more than half of the adult population. Obesity has been related to disorders such as type-2 diabetes, non-alcoholic fatty liver disease, and cardiovascular diseases, among others, which has made obesity the second cause of preventable death, only behind smoking. Bearing this in mind, it is necessary to find new strategies to overcome overweight/obesity and its associated pathologies. In this context, nutraceuticals and dietary supplements have become interesting tools thanks to their composition, rich in bioactive compounds beneficial to health. Among bioactive compounds, this study will focus on β-glucans, a type of soluble dietary fiber, and hydroxycinnamic acids, a group of phenols. Both types of compounds show complex and multifactorial effects, acting as hypolipemic, hypoglycemic, antioxidant, prebiotic and satiating agents. They act by modulating different metabolic pathways, affecting the absorption and metabolism of lipids and carbohydrates, reducing oxidative damage, promoting the proliferation of beneficial bacterial species, and reducing dietary intake. It may be concluded that both beta-glucans and hydroxycinnamates have potential as nutritional tools for the management of obesity and its associated metabolic dysfunctions.

          Influence of diet on the gut microbiome and implications for human health

          Recent studies have suggested that the intestinal microbiome plays an important role in modulating risk of several chronic diseases, including inflammatory bowel disease, obesity, type 2 diabetes, cardiovascular disease, and cancer. At the same time, it is now understood that diet plays a significant role in shaping the microbiome, with experiments showing that dietary alterations can induce large, temporary microbial shifts within 24 h. Given this association, there may be significant therapeutic utility in altering microbial composition through diet. This review systematically evaluates current data regarding the effects of several common dietary components on intestinal microbiota. We show that consumption of particular types of food produces predictable shifts in existing host bacterial genera. Furthermore, the identity of these bacteria affects host immune and metabolic parameters, with broad implications for human health. Familiarity with these associations will be of tremendous use to the practitioner as well as the patient.

            Polyphenols: chemistry, dietary sources, metabolism, and nutritional significance.

            Polyphenols constitute one of the most numerous and ubiquitous groups of plant metabolites and are an integral part of both human and animal diets. Ranging from simple phenolic molecules to highly polymerized compounds with molecular weights of greater than 30,000 Da, the occurrence of this complex group of substances in plant foods is extremely variable. Polyphenols traditionally have been considered antinutrients by animal nutritionists, because of the adverse effect of tannins, one type of polyphenol, on protein digestibility. However, recent interest in food phenolics has increased greatly, owing to their antioxidant capacity (free radical scavenging and metal chelating activities) and their possible beneficial implications in human health, such as in the treatment and prevention of cancer, cardiovascular disease, and other pathologies. Much of the literature refers to a single group of plant phenolics, the flavonoids. This review offers an overview of the nutritional effects of the main groups of polyphenolic compounds, including their metabolism, effects on nutrient bioavailability, and antioxidant activity, as well as a brief description of the chemistry of polyphenols and their occurrence in plant foods.

              Obesity: a chronic relapsing progressive disease process. A position statement of the World Obesity Federation

              This paper considers the argument for obesity as a chronic relapsing disease process. Obesity is viewed from an epidemiological model, with an agent affecting the host and producing disease. Food is the primary agent, particularly foods that are high in energy density such as fat, or in sugar-sweetened beverages. An abundance of food, low physical activity and several other environmental factors interact with the genetic susceptibility of the host to produce positive energy balance. The majority of this excess energy is stored as fat in enlarged, and often more numerous fat cells, but some lipid may infiltrate other organs such as the liver (ectopic fat). The enlarged fat cells and ectopic fat produce and secrete a variety of metabolic, hormonal and inflammatory products that produce damage in organs such as the arteries, heart, liver, muscle and pancreas. The magnitude of the obesity and its adverse effects in individuals may relate to the virulence or toxicity of the environment and its interaction with the host. Thus, obesity fits the epidemiological model of a disease process except that the toxic or pathological agent is food rather than a microbe. Reversing obesity will prevent most of its detrimental effects.
