[The ketogenic diet: an underappreciated therapeutic option?].

2011

Obesity is reaching epidemic proportions in Western countries and is a strong risk factor for cardiovascular disease. Despite the constant recommendations of health care organizations regarding the importance of weight control, this goal often fails. Although there is a common agreement about the concept that exercise and diet are two key factors for the control of body weight, the ideal amount and type of exercise and also the ideal diet for weight control are still under debate. A widely accepted nutritional regime is the Mediterranean diet that has evident health benefits although less attention has been paid to see if the effects are due to other lifestyle factors which may contribute t…

La Dieta mediterranea per tutto l'anno

2016

La promozione e la valorizzazione della Dieta Mediterranea come strumento di prevenzione primaria delle principali malattie cardiovascolari, metaboliche, oncologiche e degenerative è l’obiettivo di Idimed e questo opuscolo è uno degli strumenti della sua strategia di divulgazione. Idimed, fedele alla sua impostazione sistemica, ha sempre parlato di alimentazione a 360°, integrando i diversi aspetti del fenomeno: culturali, salutistici, agronomici, botanici, gastronomici, psicologici, relazionali e della comunicazione. Far conoscere l’alimento, descrivere la realizzazione della ricetta, fornire indicazioni su quantità, uso dei condimenti, specificità della tradizione e raccomandazioni saluti…

Dieta e prestazioni fisiche nei giocatori di calcio professionisti. L’individualizzazione in base ai ruoli ed ai carichi di allenamento e l’incidenza…

INTRODUZIONE Sebbene numerosi studi abbiano riportato che una dieta equilibrata è essenziale per migliorare la performance e i tempi di recupero in atleti professionisti, altri studi condotti su giovani giocatori di calcio di età compresa tra i 13-17 anni hanno evidenziato che l’introito calorico e la qualità dei macronutrienti non erano adeguati alla spesa energetica e alle razioni dietetiche raccomandate (Iglesias-Gutiérrez et al., 2008, Russell et al., 2011). OBIETTIVI Gli obiettivi del presente studio sono stati quelli di ottenere, elaborare e rendere note sia alla comunità scientifica che a quella degli sportivi, informazioni sulle varie metodologie di monitoraggio del dispendio energe…

Preconceptional nutrition and pregnancy outcomes: review and Dietitian-Nutritionist intervention proposal

2016

El estado nutricional de la madre antes y durante el embarazo se constata en los últimos años como uno de los factores ambientales más influyentes en el desarrollo fetal. Este estudio se centra en las primeras fases del proceso de gestación o periodo periconcepcional: preconcepción, concepción, implantación, placentación y embriogénesis; puesto que representan un paso crítico en los resultados del embarazo. Tras una revisión bibliográfica exhaustiva de 66 investigaciones publicadas entre los años 1990 y 2015, fueron el zinc, el hierro, el yodo, los ácidos grasos omega-3, el ácido fólico y otras vitaminas del grupo B, los minerales y micronutrientes para los que se han encontrado mayor evide…

Trattamento non farmacologico dell'ipertensione arteriosa

2022

Un adeguato trattamento dell’ipertensione arteriosa include sia la terapia farmacologica sia quella non farmacologica, mirando ad ottenere un effetto additivo e complementare. Le modificazioni dello stile di vita costituiscono il trattamento non farmacologico di prima scelta della malattia ipertensiva, come indicato da tutte le Linee guida internazionali. Uno stile di vita sano può prevenire o ritardare l’insorgenza dello stato ipertensivo e può ridurre il rischio cardiovascolare del paziente iperteso, oltre ad offrire la possibilità di aumentare l’efficacia antipertensiva della terapia farmacologica.

Dietary fiber and health outcomes: an umbrella review of systematic reviews and meta-analyses

2018

Background Several studies have suggested that higher consumption of dietary fiber is beneficial for a variety of health outcomes. However, many results have been inconclusive and, to our knowledge, there has been no attempt to systematically capture the breadth of outcomes associated with dietary fiber intake or to systematically assess the quality and the strength of the evidence on the associations of dietary fiber intake and different health outcomes or medical conditions. Objective The aim of this study was to describe the diverse health outcomes convincingly associated with dietary fiber consumption. Design This was an umbrella review of systematic reviews with meta-analysis of observ…

Antioxidant and Anti-Inflammatory Potential of Polyphenols Contained in Mediterranean Diet in Obesity: Molecular Mechanisms

2021

Nutrition transition can be defined as shifts in food habits, and it is characterized by high-fat (chiefly saturated animal fat), hypercaloric and salty food consumption at the expense of dietary fibers, minerals and vitamins. Western dietary patterns serve as a model for studying the impact of nutrition transition on civilization diseases, such as obesity, which is commonly associated with oxidative stress and inflammation. In fact, reactive oxygen species (ROS) overproduction can be associated with nuclear factor-κB (NF-κB)-mediated inflammation in obesity. NF-κB regulates gene expression of several oxidant-responsive adipokines including tumor necrosis factor-α (TNF-α). Moreover, AMP-act…

Advanced strategy to exploit wine-making waste by manufacturing antioxidant and prebiotic fibre-enriched vesicles for intestinal health.

2020

Grape extract-loaded fibre-enriched vesicles, nutriosomes, were prepared by combining antioxidant extracts obtained from grape pomaces and a prebiotic, soluble fibre (Nutriose®FM06). The nutriosomes were small in size (from ∼140 to 260 nm), homogeneous (polydispersity index < 0.2) and highly negative (∼ −79 mV). The vesicles were highly stable during 12 months of storage at 25 °C. When diluted with warmed (37 °C) acidic medium (pH 1.2) of high ionic strength, the vesicles only displayed an increase of the mean diameter and a low release of the extract, which were dependent on Nutriose concentration. The formulations were highly biocompatible and able to protect intestinal cells (Caco-2) fro…

Functional implications of bound phenolic compounds and phenolics–food interaction: A review

2022

Sizeable scientific evidence indicates the health benefits related to phenolic compounds and dietary fiber. Various phenolic compounds-rich foods or ingredients are also rich in dietary fiber, and these two health components may interrelate via noncovalent (reversible) and covalent (mostly irreversible) interactions. Notwithstanding, these interactions are responsible for the carrier effect ascribed to fiber toward the digestive systemand canmodulate the bioaccessibility of phenolics, thus shaping health-promoting effects in vivo. On this basis, the present review focuses on the nature, occurrence, and implications of the interactions between phenolics and food components. Covalent and nonc…

Vegetable and Fruit Intakes Are Associated with hs-CRP Levels in Pre-Pubertal Girls

2017

The influence of diet on inflammation in children remains unclear. We aimed to analyze the influence of diet on high-sensitivity C-reactive protein (hs-CRP) levels in a pre-pubertal population free of other influences that may affect hs-CRP levels. We determined hs-CRP levels in 571 six- to eight-year-old children using an hs-CRP ELISA kit. Information on food and nutrient intake was obtained through a food-frequency questionnaire. Overall dietary quality was assessed using the Healthy Eating Index (HEI). We found that girls in the highest tertile of hs-CRP levels had a higher intake of saturated fatty acid, and lower intakes of fiber and vitamin E and a lower HEI score when compared to tho…
