Apple-products phytochemicals and processing: a review.

2009

Epidemiological studies have linked the consumption of apples with reduced risk of some cancers, cardiovascular disease, asthma, and diabetes. Extensive research exists on apples and the health benefits of their beverages and phytochemicals. The purpose of this paper is to review the most recent literature in this area focusing on phytochemicals, phytochemical bioavailability and antioxidant behavior.

Are the Recommended Dietary Allowances for Vitamins Appropriate for Elderly People?

2015

Background: An adequate vitamin intake is essential for a good nutritional status, especially in older women, who are more sensitive to nutritional deficiencies. The American, European and Italian Recommended Dietary Allowances (RDAs) derive mainly from studies on adults, and it is not clear whether they also apply to elderly people. Comparing the RDAs with the actual vitamin intake of a group of healthy older women could help to clarify the real needs of elderly people. Objective: Our aim was to compare the American, European, and Italian RDAs with the actual vitamin intake of a group of healthy older women. Design: This was a cross-sectional study. Participants: The study included 286 hea…

Cyclic antibiotic therapy for diverticular disease: a critical reappraisal.

2010

Different symptoms have been attributed to uncomplicated diverticular disease (DD). Poor absorbable antibiotics are largely used for uncomplicated DD, mainly for symptom treatment and prevention of diverticulitis onset. Controlled trials on cyclic administration of rifaximin in DD patients were evaluated. Four controlled, including 1 double-blind and 3 open-label, randomized studies were available. Following a long-term cyclic therapy, a significant difference emerged in the global symptoms score (range: 0-18) between rifaximin plus fibers (from 6-6.5 to 1-2) and fibers alone (from 6.7 to 2-3.8), although the actual clinically relevance of such a very small difference remains to be ascertai…

Characterization of a new natural fiber from Arundo donax L. as potential reinforcement of polymer composites.

2013

Abstract The aim of this paper is to study the possibility of using of Arundo donax L. fibers as reinforcement in polymer composites. The fibers are extracted from the outer part of the stem of the plant, which widely grows in Mediterranean area and is diffused all around the world. To use these lignocellulosic fibers as reinforcement in polymer composites, it is necessary to investigate their microstructure, chemical composition and mechanical properties. Therefore, the morphology of A. donax L. fibers was investigated through electron microscopy, the thermal behavior through thermogravimetric analysis and the real density through a helium pycnometer. The chemical composition of the natura…

Effect of Supplementation with Wheat Bran Aqueous Extracts Obtained by Ultrasound-Assisted Technologies on the Sensory Properties and the Antioxidant…

2015

Phenolic compounds have antioxidant properties and activate endogenous detoxification defense systems able to scavenge the reactive species of oxygen. The external layers of wheat caryopsis, largely constituting by-products of the milling industry such as bran and various middlings, contain relevant amounts of phenolic compounds. The aim of the research has been to evaluate the effect of supplementation with wheat bran aqueous extracts, obtained by ultrasound-assisted technologies, on the sensory properties and antioxidant activity of dry pasta. The HPLC-DAD characterization of the extract evidenced the presence of ferulic and p-coumaric acids. The supplemented pasta showed significantly h…

Influence of different soluble dietary fibers on the bioaccessibility of the minor Fusarium mycotoxin beauvericin.

2011

Abstract Beauvericin (BEA) is a bioactive compound produced by the secondary metabolism of several Fusarium strains and is known to have various biological activities. This study investigated the bioaccessibility of the BEA tested in concentrations of 5 and 25 mg/L, in a model solution and in wheat crispy breads elaborated with different natural binding compounds as the soluble alimentary dietary fibers β-1,3 glucan, chitosan low molecular weight (L.M.W.), chitosan medium molecular weight (M.M.W.), fructooligosaccharides (FOS), galattomannan, inulin and pectin, added at concentrations of 1% and 5%. The bioaccessibility was determinated by employing a simulated gastrointestinal digestion tha…

Nutraceuticals in Lipid-Lowering Treatment

2014

Lipid-lowering drugs may cause adverse effects and, although lipid targets may be achieved, a substantial residual cardiovascular (CV) risk remains. Treatment with agents mimicking proteins present in the body, such as incretin-based therapies, provided promising results. However, in order to improve lipids and CV risk, lifestyle measures remain important. Some researchers focused on nutraceuticals that may beneficially affect metabolic parameters and minimize CV risk. Chitosan, a dietary fiber, can regulate lipids with benefit on anthropometric parameters. The beneficial properties of dietary supplements (such as green tea extract, prebiotics, plant sterols, and stanols) on plasma lipids,…

USE OF PROTEIN SUPPLEMENTS AND DIETARY BEHAVIOUR: RESULTS OF A SURVEY ON PEOPLE ATTENDING COMMERCIAL GYMS IN ITALY

2011

Introduction Nutrition is traditionally perceived as a crucial component of physical fitness and performance. In the last few decades, the increasing understanding of human nutrition and exercise physiology has showed that a wise management of nutrient intake could positively affect fitness improvements and sport performance. The aim of this study was to examine the use of dietary supplements and diet behavior amongst regular fitness centers users in Italy. Methods A specific questionnaire was generated for the experimentation. The data were collected using the face-to-face interview method. Only strength and conditioning classes participants were included in the selection criteria. Trainin…

Dietary habits in children of immigrant families from developing countries: an Italian multicentre study

2006

Objectives. The aim of this study was to investigate the dietary habits of immigrant children who come to Italy from developing countries, and of their families. Methods. A multicentre cross-sectional study was carried out from Jan. 1st 2003 to Dec. 31st 2004. The study population comprised 1284 immigrant mothers, 629 infants, and 767 children with more than 2 years of age. A structured questionnaire was employed to inquire retrospectively on dietary habits and, on breastfeeding, complementary breastfeeding, bottle-feeding and weaning. Results. Exclusive and complementary breastfeeding was more frequent and of longer duration among immigrant infants than Italian infants, but not compared to…
