Approche nutritionnelle de la thérapie du syndrome de l'œil sec : prévention par les acides gras polyinsaturés

2008

Dry eye disease affects 15% of the population over the age of 65. It is characterized mainly by inflammation of the ocular surface (tear film, conjunctiva and cornea) which represents a relevant target for therapeutic strategies. The side effects and long-term intolerance of anti-inflammatory drugs give rise to an increasing interest for dietary components exhibiting anti-inflammatory properties, such as polyunsaturated fatty acids (PUFAs). In these studies, we developed a scopolamine-induced dry eye model in the rat that mimics changes occurring in Humans suffering from moderate dry eye. We described the time course of clinical signs, inflammation and mucin production loss. We investigated…

Hypertrophy and ER Stress Induced by Palmitate Are Counteracted by Mango Peel and Seed Extracts in 3T3-L1 Adipocytes

2023

A diet rich in saturated fatty acids (FAs) has been correlated with metabolic dysfunction and ROS increase in the adipose tissue of obese subjects. Thus, reducing hypertrophy and oxidative stress in adipose tissue can represent a strategy to counteract obesity and obesity-related diseases. In this context, the present study showed how the peel and seed extracts of mango (Mangifera indica L.) reduced lipotoxicity induced by high doses of sodium palmitate (PA) in differentiated 3T3-L1 adipocytes. Mango peel (MPE) and mango seed (MSE) extracts significantly lowered PA-induced fat accumulation by reducing lipid droplet (LDs) and triacylglycerol (TAGs) content in adipocytes. We showed that MPE a…

Dietary Fats and Cardio-Metabolic Outcomes in a Cohort of Italian Adults

2022

Background: Dietary fats, and especially saturated fatty acid (SFA), have been blamed for being the culprit in the dramatic increase in obesity and its associated diseases. However multiple systematic reviews and recent meta-analyses do not support the association between SFA and cardiovascular diseases. Thus, the objective of this study was to test whether specific types and subtypes of dietary fats are associated with metabolic outcomes in a cohort of Italian adults. Methods: Nutritional and demographic data of 1936 adults living in the south of Italy were examined. Food frequency questionnaires (FFQs) were administered to assess the intake of total dietary fat and each specific class of …

Amaranthus grain as a new ingredient in diets for dairy cows: productive, qualitative, and in vitro fermentation traits

2022

Background: In recent decades, grain amaranths have attracted attention due to their valuable combination of nutritional traits, with higher protein and oil content than conventional cereals. Before they can be proposed as an unconventional ingredient in animal feed, many aspects still need to be investigated from field production to nutritive value. The present research aimed to study the agronomic traits, proximate composition, and digestibility/degradability, fatty acid profile, antioxidant activity, and total phenolic content of two grain amaranth species, Amaranthus cruentus and Amaranthus hypochondriacus (for a total of six accessions), grown in a Mediterranean environment. Results: B…

Chemical partitioning and DNA fingerprinting of some pistachio (Pistacia vera L.) varieties of different geographical origin

2019

The genus Pistacia (Anacardiaceae family) is represented by several species, of which only P. vera L. produces edible seeds (pistachio). Despite the different flavor and taste, a correct identification of pistachio varieties based on the sole phenotypic character is sometimes hard to achieve. Here we used a combination of chemical partitioning and molecular fingerprinting for the unequivocal identification of commercial pistachio seed varieties (Bronte, Kern, Kerman, Larnaka, Mateur and Mawardi) of different geographical origin. The total phenolic content was higher in the variety Bronte followed by Larnaka and Mawardi cultivars. The total anthocyanin content was higher in Bronte and Larnak…

Antioxidant activity and fatty acids quantification in Sicilian purslane germplasm

2019

Portulaca oleracea is an annual succulent herb in the family Portulacaceae. It is a nutritious vegetable with high antioxidant properties and, it is among the richest plant source of ω-3 fatty acids, as well as a rich source of ω-6 fatty acids, ascorbic acid, tocopherols and beta-carotene. In the present study, three purslane populations under different Mediterranean environmental conditions for two years, for future valorization as novel food sources of omega-3 fatty acids, were evaluated. In particular, biomorphological characteristics, total phenols and fatty acids content were determined. The antioxidant activities were evaluated using 2,2-diphenyl-1-picrylhydrazyl assay. The population…

Omega-3 rich foods: Durum wheat spaghetti fortified with Portulaca oleracea

2020

Abstract Portulaca oleracea is an annual succulent herb (purslane) with high antioxidant properties and high content of essential ω-3 and ω-6 fatty acids, ascorbic acid, α-tocopherol and β-carotene. In the present study, sensorial and chemical analyses of uncooked and cooked durum wheat pasta fortified with purslane from three different Sicilian areas and at three different concentrations (5, 10 and 15%) were estimated. The sensorial analysis showed that the scores of the overall acceptance decreased considerably in pasta with 15% purslane, while consumers appreciated pasta samples with 10% purslane. Chemical analysis highlighted that the addition of purslane gave pasta samples the potentia…
