Dimensions of Mediterranean Diet: world cultural heritage

The book "Dimensions of Mediterranean diet" develops the reflection around the Mediterranean Diet concept - Intangible Cultural Heritage, which took place by initiative of the University of Algarve, during the first cycle of Seminars on Mediterranean Diet, in 2013. Starting with the multiplicity of this concept, the authors follow exploring the reality of this way of life (between the sky and the earth), which is the result of an age-old training process, integrates a habit of eating well in a healthy life practice and is a vehicle for future sustainability. The images accompanying the text portray this Mediterranean identity, straight from Algarve current realities.

Citrus as a component of the Mediterranean Diet

Citrus are native to southeastern Asia, but are present in the Mediterranean basin for centuries. This group of species has reached great importance in some of the Mediterranean countries and, in the case of orange, mandarin and lemon trees, they found here soil and climatic conditions which allows them to achieve a high level of fruit quality, even better than in the regions where they came from. Citrus fruits are present in the diet of the peoples living on the Mediterranean basin, at least since the time of the Roman Empire. In the 20th century they became the main crop in various agricultural areas of the Mediterranean, playing an important role in the landscape, in the diet of the overall population, and also in international trade. They are present in the gardens of palaces and monasteries, but also in the courtyards and orchards of the poorest families. Their fruits are not only a refreshing dessert, but also a condiment, or even a major component of many dishes. Citrus fruits have well-documented nutritional and health benefits. They can actually help prevent and cure some diseases and, above all, they are essential in a balanced and tasty diet.

AB1258­HPR pilot study: does a mediterranean diet­based weight loss programme improve health outcomes in overweight older women with knee osteoarthritis?

Osteoarthritis (OA) is one of the leading causes of pain and disability among older adults, particularly women. Pain and mobility disability are major consequences of knee OA which and can interfere with the functional autonomy of elderly and thus, making it difficult to perform activities of daily living. Evidence suggests that obesity is strongly linked to knee OA and that non­pharmacological therapy should be based on physical activity and weight loss in case of overweight and obesity. A positive relationship between adherence to the Mediterranean diet and health outcomes has been widely discussed in scientific literature, including its potential benefits in weight loss.

Gastronomia Algarvia/Dieta Mediterrânica?

The Mediterranean Diet concept was formulated during the sixties, in association with the food consumption pattern of Mediterranean areas that produced olive oil and shared common health styles. These areas, besides their own cultural and religious differences, share common food habits, such as: - The use of olive oil (supplier of monounsaturated fatty acids and antioxidants); - The abundant use of cereals, mainly under the form of excellent quality bread, flour and pasta (providing fibre and energy); - Large and variegate consumption of fruit (fresh and dried), nuts and vegetables (colourful, rich in fibre, antioxidants and other protective materials); - Abundant use of herbs and spices (rich in antioxidants and other protective materials); - Simple culinary methods, using short cooking times and low temperatures (which enhance the preservation of food nutritional and sensorial characteristics). The Mediterranean Diet reflects a set of characteristics that make it internationally recognized as a health promoter eating pattern, where the relation between monounsaturated and saturated fatty acids is highly advantageous for the former, fibre, vitamins and natural antioxidants intake is high, together with a low consumption of animal protein and salt. The obtained results show contents in protein, lipid and carbohydrates very adequate to the “DRI”; The relation between mono and saturated fatty acids (40:9) should be emphasised, together with the high fibre content. Protective nutrients show remarkable results, with a wide variety of vitamins and minerals, in particular Vitamin A, complex B vitamins, biotin, vit. E, folic acid, iron, manganese and selenium, that are widely recognised as important antioxidants and responsible for the good function of the immune system. In conclusion, tomato soup, consumed traditionally as a poor meal, shows to be a health promoter nutritionally complete recipe.

Effect of polyunsaturated fatty acids (PUFAs) on the proliferation and extracellular matrix mineralization and gene expression of gilthead seabream skeletal cell lines

The aquaculture industry aims at replacing significant amounts of marine fish oil by vegetable oils in fish diet. Dietary lipids have been shown to alter the fatty acid composition of bone compartments, which would impact the local production of factors controlling bone formation. Knowledge on the mechanisms underlying the nutritional regulation of bone metabolism is however scarce in fish. Two in vitro bone-derived cell systems developed from seabream (an important species for aquaculture in the Mediterranean region) vertebra, capable of in vitro mineralization and exhibiting prechondrocyte (VSa13) and pre-osteoblast (VSa16) phenotype, were used to assess the effect of certain polyunsaturated fatty acids (PUFAs; arachidonic (AA), eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids) on cell proliferation, extracellular matrix (ECM) mineralization and gene expression. While all PUFAs promoted morphological changes in both cell lines, VSa16 cell proliferation appeared to be stimulated by PUFAs in a dose dependent manner until 100M, whereas proliferation of VSa13 cells was impaired at concentrations above 10M. AA, EPA and DHA inhibited VSa13 ECM mineralization, alone and in combination, while VSa16 ECM mineralization was only inhibited by AA and EPA. DHA had the opposite effect, increasing mineralization almost by 2 fold. When EFAs were combined, DHA apparently compensated for the inhibitory effect of AA and EPA. Expression of marker genes for bone and lipid metabolisms has been investigated by qPCR and shown to be regulated in pre-osteoblasts exposed to individual PUFAs. Our results show that PUFAs are effectors of fish bone cell lines, altering cell morphology, proliferation and mineralization when added to culture medium. This work also demonstrates the suitability of our in vitro cell systems to get insights into mineralization-related effects of PUFAs in vivo and to evaluate the replacement of fish oils by vegetable oil sources in fish feeds.

The economic effects of common agricultural policy on Mediterranean montado/dehesa ecosystem

The decoupling of CAP payments leads production decisions and resources allocation to be more dependent on market prices and competitive advantages. The objective of this paper is to assess the effects of CAP trends on the montado/dehesa traditional ecosystem of Mediterranean regions in terms of farm income, land, labour and capital. A positive mathematical supply model disaggregated by the montado agro-forestry production systems of the Alentejo region in southern Portugal is developed. The results show that decoupling payments of CAP have negative economic effects on agricultural activities and resource use. Agricultural income increases with single farm payments but the foreseen increases in prices do not compensate the loss of the Agenda 2000 area payments in terms of competitiveness. These results reinforce the need to promote alternative agricultural and non-agricultural activities and policies in Mediterranean rural European areas and regions.

Yeast diversity in the Mediterranean strawberry tree (Arbutus unedo L.) fruits' fermentations

In the Mediterranean region the fruits of the strawberry tree (Arbutus unedo L.) may be fermented and distilled to produce a traditional beverage very much appreciated in Southern Europe. The aim of the present work was to study the diversity of the yeast population and the killer activity of the isolates identified as Saccharomyces cerevisiae, obtained during solid state industrial fermentations of the arbutus berries. The identification of the isolates was performed by the 5.8S rRNA-ITS region restriction analysis and by sequencing the D1/D2 region of the large subunit of the rRNA gene. At the start of the fermentations, various non-Saccharomyces species were detected including Aureobasidium pullulans, Dothichiza pithyophila, Dioszegia zsoltii, Hanseniaspora uvarum and yeasts belonging to the genera Metschnikowia, Cryptococcus and Rhodotorula. However, as the biological processes progressed the number of different species decreased with S. cerevisiae and Pichia membranaefaciens becoming dominant at advanced stages of the must fermentation that is characterized by high concentrations of ethanol. Forty three isolates identified as S. cerevisiae were tested for killer activity against two sensitive reference strains and Zygosaccharomyces bailii. Their killer sensitivity in relation to five killer referenced toxins (K2, K5, K8, K9 and K10) was also studied. Out of the isolates analyzed, 95.3% were sensitive and 4.7% were tolerant against the killer toxins tested. Only three isolates revealed killer activity against one sensitive strain and two of them against the spoiler yeast Z. bailii. The microbiota obtained revealed an interesting potential to be used as starter cultures to overcome unpredictable uncontrolled fermentations of the arbutus fruits as well as in other applications of biotechnological interest.
