Influence of tree's structure on the efficiency of the mechanical harvest of olives
2008
This study represents an analysis about the influence of the structure of the plant and the drupes’ position on the efficiency of the mechanical harvest of olives. The aim is to study the eventual correlations between some geometrical characteristics of the plants and the harvest efficiency. The experimental tests were carried out in an olive grove sited in Castelvetrano, province of Trapani; the variety was Nocellara del Belice, the plants “globe” shaped. Some morphological surveys were carried out on a sample of trees. The mechanical harvest was performed with a trunk shaker provided with an upside down umbrella. After the harvest, the residual production was quantified for each bud in or…
Data from: Genetic relationships, structure and parentage simulation among the olive tree (Olea europaea L. subsp. europaea) cultivated in Southern I…
2013
In this work, we assess both the morphological and genetic diversity of 68 important olive cultivars from three Southern Italian regions: Calabria, Campania and Sicily. Twenty-five phenotypic traits were evaluated and 12 simple sequence repeat (SSR) markers were analysed. All SSR primers were polymorphic and reliable. The total number of alleles per locus varied from 5 to 19 with an average number of 13.1 and a mean polymorphic information content (PIC) of 0.81. These results suggested high genetic diversity within these three olive germplasm collections. Morphological traits also showed significant variability amongst cultivars. Two cases of identity were found and ten statistically signif…
Effect of a Mediterranean Diet Intervention on Dietary Glycemic Load and Dietary Glycemic Index: The PREDIMED Study
2014
© 2014 Ana Isabel Rodríguez-Rejón et al. Objective. To compare the one year effect of two dietary interventions with MeDiet on GL and GI in the PREDIMED trial. Methods. Participants were older subjects at high risk for cardiovascular disease. This analysis included 2866 nondiabetic subjects. Diet was assessed with a validated 137-item food frequency questionnaire (FFQ). The GI of each FFQ item was assigned by a 5-step methodology using the International Tables of GI and GL Values. Generalized linear models were fitted to assess the relationship between the intervention group and dietary GL and GI at one year of follow-up, using control group as reference. Results. Multivariate-adjusted mode…
Olive oil consumption and risk of CHD and/or stroke: a meta-analysis of case–control, cohort and intervention studies
2014
Increasing evidence suggests that the Mediterranean diet can reduce the risk of CVD. Olive oil is the hallmark of this dietary pattern. We conducted a meta-analysis of case–control, prospective cohort studies and a randomised controlled trial investigating the specific association between olive oil consumption and the risk of CHD (101 460 participants) or stroke (38 673 participants). The results of all observational studies were adjusted for total energy intake. The random-effects model assessing CHD as an outcome showed a relative risk (RR) of 0·73 (95 % CI 0·44, 1·21) in case–control studies and 0·96 (95 % CI 0·78, 1·18) in cohort studies for a 25 g increase in olive oil consumption. In …
Mediterranean diet and antihypertensive drug use: a randomized controlled trial
2021
Objective To examine in older individuals at high cardiovascular risk whether following a Mediterranean diet decreased the necessity of antihypertensive drugs and modulated their associated cardiovascular risk. Methods In the PREvencion con DIeta MEDiterranea study, we assessed whether volunteers randomly allocated to an intervention with a Mediterranean diet enriched with extra-virgin olive oil or nuts (relative to a low-fat control diet) disclosed differences in the risk of: initiating antihypertensive medication in nonusers at baseline (n = 2188); and escalating therapy in participants using one, two, or three drugs at baseline (n = 2361, n = 1579, and n = 554, respectively). We also ass…
Can adherence to the Mediterranean diet prevent myocardial infarction? Answers from an Italian study
2015
Background The Mediterranean-style diet, with a focus on vegetables, fruit, fish, whole grains, and olive oil, has proven to reduce cardiovascular events. This case control study add epidemiological data, covering the lack in Italian context, on the association between adherence to the Mediterranean diet (MDA) and non-fatal acute myocardial infarction (AMI) in multicenter study covering …
The Mediterranean diet improves the systemic lipid and DNA oxidative damage in metabolic syndrome individuals. A randomized, controlled, trial.
2013
Summary Background & aims Metabolic syndrome (MetS), in which a non-classic feature is an increase in systemic oxidative biomarkers, presents a high risk of diabetes and cardiovascular disease (CVD). Adherence to the Mediterranean Diet (MedDiet) is associated with a reduced risk of MetS. However, the effect of the MedDiet on biomarkers for oxidative damage has not been assessed in MetS individuals. We have investigated the effect of the MedDiet on systemic oxidative biomarkers in MetS individuals. Methods Randomized, controlled, parallel clinical trial in which 110 female with MetS, aged 55–80, were recruited into a large trial (PREDIMED Study) to test the efficacy of the traditional MedDie…
The Mediterranean Diet and Cardiovascular Epidemiology
2006
The Mediterranean diet was first considered to be a low-saturated fat diet that conveyed protection against coronary heart disease by lowering plasma total cholesterol levels. Later, the emphasis shifted away from the low-saturated-fat content of this diet toward its high content of olive oil and its overall constellation of characteristics. Moreover, there is now evidence that the Mediterranean diet benefits not only the risk for coronary heart disease but also cancer occurrence, total mortality, and longevity.

Diet to Reduce the Metabolic Syndrome Associated with Menopause. The Logic for Olive Oil
2020
The rates of metabolic syndrome are increasing in parallel with the increasing prevalence of obesity, primarily due to its concomitant insulin resistance. This is particularly concerning for women, as the years around menopause are accompanied by an increase in visceral obesity, a strong determinant of insulin resistance. A fall in estrogens and increase in the androgen/estrogen ratio is attributed a determining role in this process, which has been confirmed in other physiological models, such as polycystic ovary syndrome. A healthy lifestyle, with special emphasis on nutrition, has been recommended as a first-line strategy in consensuses and guidelines. A consistent body of evidence has ac…
