The aim of this study was to evaluate adherence to the Mediterranean diet (MedDiet) among children and adolescents with type 1 diabetes (T1D) in relation to metabolic control. Adherence to the MedDiet was assessed with the Mediterranean Diet Quality Index (KIDMED) questionnaire and physical activity by the International Physical Activity Questionnaire for Adolescent (IPAQ-A) on 65 subjects (32 males, 9–18 years) with T1D. The promotion of the MedDiet, mainly having a healthy breakfast, is a good strategy to include in the management of T1D to improve glucose and metabolic control. This research is valuable for parents to obtain the best results for their children with T1D.
Mediterranean dietary pattern is more important than that of its individual food groups. On one hand, for some foods, there was not a big difference between the most extreme consumption categories; therefore, the effect of high or low consumption would be more difficult to be observed. As more foods are included, these differences will grow. On the other hand, although we found a significant inverse association between dairy products and COVID-19, the effect of the Mediterranean diet is the combined effect of all its components, which can combine and enhance each other. Undoubtedly, the recommendation of a complete pattern is much more effective than that of isolated foods.
Cardiovascular diseases (CVDs) are still the leading cause of death and disability worldwide, and they could be prevented by a diet modification and a healthy lifestyle. Dietary modifications include a reduction in the consumption of saturated fatty acids and replacing them with mono or polyunsaturated fatty acids. Olive oil is a monounsaturated fatty acid, and its increased consumption has been associated with a significant reduction of CVDs
Italian olive growing must aim at the transition to economically and environmentally sustainable management systems, linked to premium quality production and to a recognized and remunerated context of biodiversity conservation in compliance with the provisions of the European Union New Green Deal and United Nations Agenda 2030. To assist and facilitate companies in this step, a sustainability technical guide for the Italian olive oil supply chain has been developed, with reference to the four pillars of sustainability.
The processing of olives for oil production generates the most abundant agro-industrial by-products in the Mediterranean area. The three-phase olive oil extraction process requires the addition of a large amount of water to the system, which is difficult to dispose of for its load of toxic pollutants. On the other hand, olive mill wastewater is a rich source of bioactive substances with various biological properties that can be used as ingredients in the food industry for obtaining functional and nutraceutical foods as well as in the pharmaceutical industry. In this study, we present the results relative to the phenolic compounds detected in dried olive mill wastewaters obtained using a spray dryer. The results obtained highlighted that the use of dehumidified air as a drying medium, with the addition of maltodextrin, appears to be an effective way to produce a phenol-rich powder to be included in food formulations as well as in pharmaceutical preparations having different biological properties.
It is well-accepted that the endogenous antioxidant protection system progressively decays in elderly people, and that the oxidative stress contributes to different neurodegenerative disorders such as Alzheimer’s Diseases (AD). The lower incidence of AD in countries which feature the Mediterranean Diet was associated to the high consumption of extra virgin olive oil and its polyphenolic fraction, in particular hydroxytyrosol. The protective role of these bio-phenols against oxidative stress, suggested that we combine their antioxidant/free radical scavenging activity with donepezil, an active ingredient which has just been approved for the treatment of AD.
Virgin olive oil (VOO) provides an important source of healthy compounds. Its high concentrations of monounsaturated fatty acids and phenolic compounds contribute toward its nutritional, antioxidant, and antimicrobial properties. VOO is used in the preparation of many dishes worldwide and forms a staple of the Mediterranean diet; however, the antimicrobial activity of VOO in food matrices has been investigated very little to date. Considering this and the growing demand to reduce the use of synthetic antimicrobials and chemical food preservatives, especially in minimally processed foods, the aim of this work was to evaluate the antibacterial activity of VOOs obtained from 13 different Italian olive varieties. This study provides evidence supporting that VOOs with determinate polyphenols profiles might be used as antimicrobial ingredients in minimally processed foods to significantly reduce the presence of pathogenic bacteria.
The Mediterranean diet (MD) is becoming a milestone for the prevention of chronic diseases, such as cardiovascular diseases (CVDs), Alzheimer’s and Parkinson’s disease. Ancel Keys in the 1950’s showed a low mortality rate, particularly for coronary heart disease, among people resident in the Mediterranean area. The MD is characterized by the intake of the high amount of vegetables, fruit, and cereals and regular but moderate consumption of wine, fish, and dairy products, while olive oil is the main source of culinary fat. Therefore, it is principally a plant-based diet rich in polyphenols, a heterogeneous category of compounds with different properties and bioavailabilities. Among polyphenols, anthocyanins have been combined into the human food regime for centuries. They have been utilized as traditional herbal remedies for their ability to treat several conditions, as potent anti-oxidants, anti-diabetic and anti-carcinogenic compounds. This review summarizes our knowledge on the health-enhancing component of the anthocyanins-rich diet.
Olive pomace (OP) is the main by-product of olive oil extraction. After pit and skin removal, OP pulp has high concentrations of dietary fiber and phenolics with high antioxidant capacity. This study evaluated mice health benefits of drum-dried pitted OP pulp obtained after first and second oil extraction. Drum-dried pitted olive pomace can be produced from first or second olive oil extraction byproducts to be used as a shelf-stable healthy food or feed supplement.
This post reports the results of the first randomized trial finding an effect of a long-term dietary intervention on breast cancer incidence. The results suggest a beneficial effect of a Mediterranean diet supplemented with extra-virgin olive oil in the primary prevention of breast cancer. These results come from a secondary analysis of a previous trial and are based on few incident cases and, therefore, need to be confirmed in longer-term and larger studies.
