Progression Of Atherosclerosis

The protective effects of a dietary intervention as a useful tool in the prevention of atherosclerosis disease has gained greater attention in recent years. Several epidemiological studies have demonstrated the importance of diet in reducing expensive treatments or possible undesirable side effects. The main aim of this review is to examine the effects of specific nutrients on the development and progression of atherosclerosis in patients with cardiovascular disease. Various mechanisms have been proposed to explain the cardioprotective effect of different nutrients. In this sense, results have shown stabilization of vulnerable atherosclerotic plaques or downregulation of biomarkers related to inflammation through nutrients such as Omega-3 polyunsaturated fatty acids, hydroxytyrosol of extra virgin olive oil, lycopen, phytosterols of plants, or flavonols of fruits and vegetables, among others. The accumulated evidence on the anti-inflammatory effects related to these nutrients is summarized in the present review.

The Impact

Water, especially in arid and semiarid regions, is increasingly a disputed commodity among different productive sectors; the pressure for a more sustainable use of water in agriculture will grow. The main strategy to cope with water scarcity is the use of improved, innovative, and precise deficit irrigation management practices which are able to minimize the impact on fruit yield and quality. The aim of this paper was to develop a certification index or hydroSOS quality index for extra virgin olive oil and processed table olives. The hydrosSOS fruits and vegetables are those cultivated under regulated deficit irrigation (RDI). Different indicators in three quality areas ((i) fatty acids, (ii) phenolic compounds, and (iii) sensory attributes) were identified as showing characteristic or typical responses under RDI conditions. Marks or scores were assigned to each one of these indicators to calculate the proposed index. It can be concluded that an extra virgin olive oil (EVOO) or processed table olives are hydroSOStainable foods, if they meet 2 conditions: (i) fulfill the conditions established in the hydroSOS “irrigation” index, and (ii) fulfill the requirements of the hydroSOS “quality” index. HydroSOS quality index will be specific to each crop and variety and will depend on functional and sensory factors.

Background and Objective: The increasing interest in the Mediterranean diet (MeDiet) hinges on the relevant role it plays in inflammatory diseases. Several clinical, epidemiological and experimental evidences suggest that consumption of the MeDiet reduces the incidence of certain pathologies related to oxidative stress, chronic inflammation and immune system diseases such as cancer, atherosclerosis and cardiovascular disease (CVD). These reductions can be partially attributed to extra virgin olive oil (EVOO) consumption which has been described as a key bioactive food because of its high nutritional quality and its particular composition of fatty acids, vitamins and polyphenols. Indeed, the beneficial effects of EVOO have been linked to its fatty acid composition, which is very rich in monounsaturated fatty acids (MUFA), and has moderate saturated and polyunsaturated fatty acids (PUFA). The current knowledge available on the beneficial effects of EVOO and its phenolic compounds, specifically its biological properties and antioxidant capacity against immune-mediated inflammatory responses (atherosclerosis, rheumatoid arthritis, diabetes, obesity, cancer, inflammatory bowel disease or neurodegenerative disease, among others) in addition to its potential clinical applications. Conclusion: The increasing body of studies carried out provides compelling evidence that olive polyphenols are potential candidates to combat chronic inflammatory states.

Reduced Risk

An increased intake of fruits and vegetables has been shown to be associated with reduced risk of cancer. In epidemiological studies, supplements of β-carotene, which is abundant in fruits and vegetables, were not found to be beneficial in reducing the incidence of lung cancer in high-risk groups. Epoxycarotenoids are abundant in nature. 5,6-Epoxy-β-carotene was much more active than β-carotene in the induction of differentiation of NB4 cells [Duitsman, Becker, Barua and Olson (1996) FASEB J. 10, A732]. Epoxycarotenes may, therefore, have protective effects against cancer. In order to do this, however, epoxycarotenoids must be absorbed by the human body. There is no evidence that epoxycarotenoids, despite their abundance in dietary fruits and vegetables, are absorbed by humans. In this paper, it is demonstrated that orally administered dietary or synthetic epoxy-β-carotenes are absorbed by humans, as indicated by their appearance in the circulating blood.

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 models showed an inverse association between GL and MeDiet + extra virgin olive oil (EVOO) group:β= −8.52 (95% CI: −10.83 to −6.20) and MeDiet + Nuts group:β= −10.34 (95% CI: −12.69 to −8.00), when comparing with control group. Regarding GI,β= −0.93 (95% CI: −1.38 to −0.49) for MeDiet + EVOO,β= −1.06 (95% CI: −1.51 to −0.62) for MeDiet + Nuts when comparing with control group.Conclusion. Dietary intervention with MeDiet supplemented with EVOO or nuts lowers dietary GL and GI.

Dietary patterns offer an alternative to the analysis of individual foods or nutrients in nutritional epidemiological studies. The aim of the present study was to identify dietary patterns common to different European countries and examine their associations with asthma. In five study centres (two in Germany, two in the UK and one in Norway), 1174 adults aged 29–55 years completed a FFQ and respiratory symptoms questionnaire. A meta-analytic approach was used to identify the dietary patterns and analyse them in relation to current asthma, asthma symptoms and bronchial responsiveness (BHR). Two patterns emerged, generally correlating with the same foods at different centres: one associated with intake of meats and potatoes; the other with fish, fruits and vegetables. There was no evidence that the fish, fruits and vegetables pattern was associated with asthma (OR 1·11 (95 % CI 0·93, 1·33)), symptom score (ratio of means 1·07 (0·98, 1·17)) or BHR (regression coefficient − 0·01 ( − 0·12, 0·10)), though these CI appeared to rule out large protective effects of consuming these foods. There was no overall evidence that the meat and potato pattern was associated with asthma (OR 1·02 (0·79, 1·31)), symptom score (ratio of means 1·07 (0·84, 1·36)) or BHR (regression coefficient − 0·08 ( − 0·27, 0·10)), but there was heterogeneity between centres in the association with symptom score: a negative association at the two German centres; a positive association at the others. Heterogeneity in a multi-centre observational study of diet could suggest alternative explanations for apparent effects of diet, such as uncontrolled confounding.

Progression Of Atherosclerosis

Epidemiological evidence suggests that the diet influences CHD risk, although the protective effects of dietary intervention for patients in diseased states has gained less attention. Secondary care prevention strategies for patients often involves drug therapy that is expensive and can result in undesirable side effects. Therefore, it is potentially beneficial to utilise other strategies, such as diet, in the management of CHD. A systematic review was conducted to examine the effects of specific nutrients on progression of atherosclerosis, vascular function, haemostasis and inflammation in CHD patients. Results show substantial evidence for the efficacy ofn–3 oils in reducing cardiovascular mortality and one mechanism may be related to the stabilisation of vulnerable atherosclerotic plaques, although the effects on progression of atherosclerosis, haemostatic activity and vascular inflammation remain equivocal. Promising data also exist for the efficacy of flavonoid-rich foods for improving endothelial function, although strong clinical endpoint evidence is lacking. The variation in the efficacy of certain nutrients in CHD patients may be explained by genetics, existing risk factors, psychosocial factors and methodological issues, although these are often not adequately taken into consideration. We conclude that there is a need to undertake more appropriately designed trials in specific clinical populations, controlling for additional lifestyle and risk factors, examining potential interactions with medications, and also establishing methods to increase compliance to dietary recommendations before specific nutrients can be widely prescribed for secondary prevention. Future research should also utilise techniques that provide a direct measure of atherosclerosis.
