A low-FODMAP diet for irritable bowel syndrome: Some answers to the doubts from a long-term follow-up

A low-FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) diet (LFD) is a possible therapy for irritable bowel syndrome (IBS). This study investigates the short-and long-term efficacy and nutritional adequacy of an LFD and the patients’ long-term acceptability. Patients’ adherence and ability to perceive the “trigger” foods were also evaluated. Seventy-three IBS patients were given an LFD (T0) and after 2 months (T1), 68 started the reintroduction phase. At the end of this period (T2), 59 were advised to go on an Adapted Low-FODMAP Diet (AdLFD) and 41 were evaluated again after a 6–24 month follow-up (T3). At each time, questionnaires and Biolectrical Impedance Vector Analysis (BIVA) were performed. The LFD was effective in controlling digestive symptoms both in the short-and long-term, and in improving quality of life, anxiety and depression, even if some problems regarding acceptability were reported and adherence decreased in the long term. The LFD improved the food-related quality of life without affecting nutritional adequacy. When data collected at T0 were compared with those collected at T2, the perception of trigger foods was quite different. Even if some problems of acceptability and adherence are reported, an LFD is nutritionally adequate and effective in improving IBS symptoms also in the long term

Low fermentable oligo-di-and mono-saccharides and polyols (Fodmaps) or gluten free diet: What is best for irritable bowel syndrome?

Irritable Bowel Syndrome (IBS) is a very common functional gastrointestinal disease. Its pathogenesis is multifactorial and not yet clearly defined, and hence, its therapy mainly relies on symptomatic treatments. Changes in lifestyle and dietary behavior are usually the first step, but unfortunately, there is little high-quality scientific evidence regarding a dietary approach. This is due to the difficulty in setting up randomized double-blind controlled trials which objectively evaluate efficacy without the risk of a placebo effect. However, a Low Fermentable Oligo-, Di-and Mono-saccharides And Polyols (FODMAP) Diet (LFD) and Gluten Free Diet (GFD) are among the most frequently suggested diets. This paper aims to evaluate their possible role in IBS management. A GFD is less restrictive and easier to implement in everyday life and can be suggested for patients who clearly recognize gluten as a trigger of their symptoms. An LFD, being more restrictive and less easy to learn and to follow, needs the close supervision of a skilled nutritionist and should be reserved for patients who recognize that the trigger of their symptoms is not, or not only, gluten. Even if the evidence is of very low-quality for both diets, the LFD is the most effective among the dietary interventions suggested for treating IBS, and it is included in the most updated guidelines

Prima rivendicazione: 1. A device for grinding and at least partially extracting moisture from vegetable raw material, comprising axisymmetric bodies (14, 15), arranged coaxially and having a relative rotary motion, each of said axisymmetric bodies (14, 15) comprising at least one annular distribution (143, 144, 150) of wall portions (145, 145’, 153), spaced by openings (146, 146’, 154), the device being characterised in that said wall portions (145, 145’, 153) of said at least one annular distribution (143, 144, 150) of said bodies are provided with cutting elements (148, 149, 155), facing each other and mutually cooperating to cut said vegetable raw material, propulsion and pumping means being further provided, said propulsion and pumping means being adapted to cause a turbulence and a differential pressure that assists the movement of the processed material through said openings (146, 146’, 154) in substantially radial directions (Y)

Il distretto e la città. Pratiche di diseguaglianza

Il capitolo, frutto di un intenso lavoro di ricerca condotto nell'ambito di un progetto di interesse nazionale (PRIN 1997), intende riflettere sui processi di mobilità sociale che coinvolgono individui, famiglie e gruppi sociali in due precisi contesti di riferimento nell'area regionale toscana: Prato e Firenze. L'analisi sulla mobilità sociale, che adotta un approccio biografico, parte dall'osservazione delle dinamiche che si registrano nelle società locali selezionate, assumendo la trasformazione sociale come processo, una processualità influenzata dall'azione di individui e famiglie ma anche da gruppi, istituzioni e associazioni. Vengono studiati i percorsi di mobilità cercando di capirne le radici e i modi reali di concretizzazione, spostando l'attenzione sui meccanismi (Elster 1989), in un'ottica processuale diretta a identificarne le differenti figurazioni sociali cui il soggetto prende parte e le loro mutazioni. Il tema si collega a quello delle reti sociali a cui gli individui appartengono, cioè al tema del rapporto tra individuo e società locale. E' infatti attraverso le reti sociali che vengono veicolate risorse strategiche (beni, servizi, informazioni e influences), per intraprendere percorsi di mobilità. Nella ricerca sono indagati non solo l'uso delle reti, i contenuti e le risorse da essi veicolati, ma anche i meccanismi generativi delle reti di relazione. L'ipotesi è che ogni network individuale sia il risultato particolare (e instabile) di una serie di transizioni operate dall'individuo tra differenti modelli di relazione (dalla famiglia ai colleghi di lavoro, dagli amici di infanzia ai compagni di scuola)
