[PMID: 38520989 DOI: 10.1016/j.foodchem.2024.139079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 03/06/2024] [Accepted: 03/18/2024] [Indexed: 03/25/2024]
Abstract
Esterification of anthocyanins with saturated fatty acids have been widely investigated, while that with unsaturated fatty acids is little understood. In this study, crude extract (purity ∼ 35 %) of cyanidin-3-O-glucoside (C3G) from black bean seed coat was utilized as reaction substrate, and enzymatically acylated with unsaturated fatty acid (oleic acid). Optimization of various reaction parameters finally resulted in the highest acylation rate of 54.3 %. HPLC-MS/MS and NMR analyses elucidated the structure of cyanidin-3-O-glucoside-oleic acid ester (C3G-OA) to be cyanidin-3-O-(6″-octadecene)-glucoside. Introduction of oleic acid into C3G improved the lipophilicity, antioxidant ability, and antibacterial activity. Further, the color and substance stability analyses showed that the susceptibility of C3G and C3G-OA to different thermal, peroxidative, and illuminant treatments were highly pH dependent, which suggested individual application guidelines. Moreover, C3G-OA showed lower toxicity to normal cell (QSG-7701) and better inhibitory effect on the proliferation of HepG2 cells than C3G, which indicated its potential anti-tumor bioactivity.

Kotzakioulafi E, Bakaloudi DR, Chrysoula L, Theodoridis X, Antza C, Tirodimos I, Chourdakis M. High Versus Low Adherence to the Mediterranean Diet for Prevention of Diabetes Mellitus Type 2: A Systematic Review and Meta-Analysis. Metabolites 2023; 13:779. [PMID: 37512486 PMCID: PMC10386129 DOI: 10.3390/metabo13070779] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 06/19/2023] [Accepted: 06/20/2023] [Indexed: 07/30/2023] Open
Abstract
Diabetes mellitus type 2 (DMT-2) presents with a growing incidence, and its complications contribute mainly to cardiovascular disease and overall mortality. DMT-2 prevention and early stage management include lifestyle modification by adopting healthy eating patterns and increasing physical activity levels. The Mediterranean diet (MD) is associated with beneficial effects on human health and has been found effective for preventing and managing DMT-2. The purpose of this meta-analysis is to investigate whether the level of MD adherence plays a role in DMT-2 prevention and to what extent. A systematic literature search in PubMed, EMBASE, Web of Science Core Collection, Scopus, and Google Scholar databases was conducted until November 2022, and related observational studies fulfilling the eligibility criteria were included. The literature search concluded with 24 studies in the qualitative analysis and 23 studies in the quantitative analysis. Of those, 18 cohort studies were eligible for meta-analysis with hazard ratio as effect size and five studies providing odds ratio as effect size. The cohort studies included 248,140 participants with a mean follow-up of 10.8 years (3 to 22 years). Individuals with high adherence to MD presented an 11% and 18% decrease in risk and odds, respectively, of developing DMT-2 compared to those with low MD adherence (HR 0.89, 95%CI 0.83 to 0.95) and (OR 0.82, 95%CI 0.72 to 0.93). In studies where the follow-up was longer than 10 years, the 12% decrease in the risk of developing DMT-2 remained (HR 0.88 95%CI 0.84 to 0.92), whereas in studies where follow-up was less than 10 years, no difference between groups with different levels of adherence was found. Long-term high MD adherence is associated with a reduced risk of developing DMT-2, but further studies are needed to confirm these results.

Abstract
We performed a systematic review and dose-response meta-analysis of randomised trials on the effects of olive oil consumption on blood lipids in adults. A systematic search was performed in PubMed, Scopus and Web of Science databases until May 2021. Randomised controlled trials (RCT) evaluating the effect of olive oil intake on serum total cholesterol (TC), TAG, LDL-cholesterol and HDL-cholesterol in adults were included. The mean difference (MD) and 95 % CI were calculated for each 10 g/d increment in olive oil intake using a random-effects model. A total of thirty-four RCT with 1730 participants were included. Each 10 g/d increase in olive oil consumption had minimal effects on blood lipids including TC (MD: 0·79 mg/dl; 95 % CI (-0·08, 1·66); I2 = 57 %; n 31, GRADE = low certainty), LDL-cholesterol (MD: 0·04 mg/dl, 95 % CI (-1·01, 0·94); I2 = 80 %; n 31, GRADE = very low certainty), HDL-cholesterol (MD: 0·22 mg/dl; 95 % CI (-0·01, 0·45); I2 = 38 %; n 33, GRADE = low certainty) and TAG (MD: 0·39 mg/dl; 95 % CI (-0·33, 1·11); I2 = 7 %; n 32, GRADE = low certainty). Levels of TC increased slightly with the increase in olive oil consumption up to 30 g/d (MD30 g/d: 2·76 mg/dl, 95 % CI (0·01, 5·51)) and then appeared to plateau with a slight downward curve. A trivial non-linear dose-dependent increment was seen for HDL-cholesterol, with the greatest increment at 20 g/d (MD20 g/d: 1·03 mg/dl, 95 % CI (-1·23, 3·29)). Based on existing evidence, olive oil consumption had trivial effects on levels of serum lipids in adults. More large-scale randomized trials are needed to present more reliable results.

Abstract
Type 2 diabetes is one of the most common noncommunicable diseases in the world. Recent studies suggest a link between type 2 diabetes and microbiota, as well as the ability to treat and prevent it using personalized approaches to nutrition. In this work, we conducted clinical studies on the effects of a personalized diet on 56 female patients. Biochemical, physical, and immunological parameters were measured by standard methods on days 1 and 18 of the experiment. Gut and oral microbiota studies were performed in dynamics on days 1, 7, 11, and 18 using real-time polymerase chain reaction. With the help of the developed information system, a personalized diet was developed for each participant of the experiment. In the group of patients following personalized diets a statistically significant decreasing levels of glucose, thymol test, creatinine, very low-density lipoprotein, urea, secretory IgA, and tumour necrosis factor-α, and improvement in all physical parameters were observed. There was a statistically significant increase in uric acid, sodium, and magnesium. Statistically significant changes in gut microbiota were observed in Enterococcus faecalis, Escherichia coli (lac+, lac-), Lactobacillus spp., and Candida spp. Such microorganisms of oral microbiota as E. faecalis, Lactobacillus spp., Pseudomonas aeruginosa, and Candida spp. demonstrated statistically significant changes. All these changes indicate an improvement in the patients' condition in the experimental group compared to the control group. Our algorithm used for the development of personalized diets for patients with diabetes type 2 demonstrated clinical efficacy of its implementation.

Abstract
The consumption of seafood and the use of fish oil for the production of nutraceuticals and fish feed have increased over the past decades due the high content of long-chain polyunsaturated omega-3 fatty acids. This increase has put pressure on the sustainability of fisheries. One way to overcome the limited supply of fish oil is to harvest lower in the marine food web. Calanus finmarchicus, feeding on phytoplankton, is a small copepod constituting a considerable biomass in the North Atlantic and is a novel source of omega-3 fatty acids. The oil is, however, different from other commercial marine oils in terms of chemistry and, possibly, bioactivity since it contains wax esters. Wax esters are fatty acids that are esterified with alcohols. In addition to the long-chain polyunsaturated omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the oil is also rich in stearidonic acid (SDA), long-chain monounsaturated fatty acids, and the long-chain fatty alcohols eicosenol and docosenol. Recent animal studies have indicated anti-inflammatory and anti-obesogenic actions of this copepod oil beyond that provided by EPA and DHA. This review will discuss potential mechanisms behind these beneficial effects of the oil, focusing on the impact of the various components of the oil. The health effects of EPA and DHA are well recognized, whereas long-chain monounsaturated fatty acids and long-chain fatty alcohols have to a large degree been overlooked in relation to human health. Recently, however the fatty alcohols have received interest as potential targets for improved health via conversion to their corresponding fatty acids. Together, the different lipid components of the oil from C. finmarchicus may have potential as nutraceuticals for reducing obesity and obesity-related metabolic disorders.

Abstract
The gut microbiota plays a fundamental role in host health and disease. Host diet is one of the most significant modulators of the gut microbial community and its metabolic activities. Evidence demonstrates that dietary patterns such as the 'Western diet' and perturbations in gut microbiome (dysbiosis) have strong associations with a wide range of human diseases, including obesity, metabolic syndrome, type-2 diabetes and cardiovascular diseases. However, consumption of Mediterranean-style diets is considered healthy and associated with the prevention of cardiovascular and metabolic diseases, colorectal cancers and many other diseases. Such beneficial effects of the Mediterranean diet might be attributed to high proportion of fibers, mono- and poly-unsaturated fatty acids, antioxidants and polyphenols. Concurrent literature has demonstrated beneficial modulation of the gut microbiome following a Mediterranean-style diet in humans as well as in experimental animal models such as rodents. We recently demonstrated similar positive changes in the gut microbiome of non-human primates consuming a Mediterranean-style diet for long term (30 months). Therefore, it is rational to speculate that this positive modulation of the gut microbiome diversity, composition and function is one of the main factors intermediating the health effects of Mediterranean diet on the host. The present perspective discusses the evidences that the Mediterranean diet induces gut microbiome modulation in rodents, non-human primates and human subjects, and discusses the potential role of gut microbiota and microbial metabolites as one of the fundamental catalysts intermediating various beneficial health effects of Mediterranean diet on the host.

Toxic aldehyde generation in and food uptake from culinary oils during frying practices: peroxidative resistance of a monounsaturate-rich algae oil. Sci Rep 2019; 9:4125.

Abstract
Human ingestion of cytotoxic and genotoxic aldehydes potentially induces deleterious health effects, and high concentrations of these secondary lipid oxidation products (LOPs) are generated in polyunsaturated fatty acid (PUFA)-rich culinary oils during high temperature frying practices. Here, we explored the peroxidative resistance of a novel monounsaturate-rich algae frying oil (MRAFO) during laboratory-simulated shallow- and domestically-based repetitive deep-frying episodes (LSSFEs and DBRDFEs respectively), the latter featuring potato chip fryings. Culinary frying oils underwent LSSFEs at 180 °C, and DBRDFEs at 170 °C: aldehydes were determined by 1H NMR analysis in samples collected at increasing heating/frying time-points. Fast food restaurant-fried potato chip serving (FFRPCS) aldehyde contents were also monitored. Substantially lower levels of aldehydes were generated in the MRAFO product than those observed in PUFA-richer oils during LSSFEs. Toxicologically-significant concentrations of aldehydes were detected in FFRPCSs, and potato chips exposed to DBRDFEs when using a PUFA-laden sunflower oil frying medium: these contents increased with augmented deep-frying episode repetition. FFRPCS aldehyde contents were 10–25 ppm for each class monitored. In conclusion, the MRAFO product generated markedly lower levels of food-penetrative, toxic aldehydes than PUFA-rich ones during LSSFEs. Since FFRPCS and DBRDFE potato chip aldehydes are predominantly frying oil-derived, PUFA-deplete MRAFOs potentially offer health-friendly advantages.

Abstract
To develop and use the hazelnut, the main composition, and the physicochemical characteristics, fatty acid compositions, triacylglycerol (TAG) distribution and tocol contents of Hazelnut (Corylus mandshurica Maxim.) which growing in Changbai mountain of Jilin province (HO1) and Anshan city of Liaoning province (HO2) in China were investigated, and the comparative study between the two hazelnut oils and American hazelnut / Turkish hazelnut were also explored. The content of crude lipid and protein in HO1 and HO2 were approximately 54% and 17%, 55% and 16%, respectively. The two hazelnut oils were abundant in unsaturated fatty acids, with the primary unsaturated fatty acids were oleic acid (78%-80%) and linoleic acid (14-16%), which accounted for above 90% of the oils. Therefore, both of the hazelnut oils were important sources of essential fatty acid. In addition, the main saturated fatty acid of the two hazelnut oils were palmitic acid (3%) and stearic acid (1-2%). The main triacylglycerols (TGA) profile were dioleolinolein (OOL), oleodilinolein (OLL) and triolein (OOO). The contents of tocol were 574.44 μg/g, 647.49 μg/g oil in HO1 and HO2, respectively, both of them were higher than that of grape seed oils (454 μg/g), olive oils (209 μg/g) and walnut oils (255 μg/g). The total phytosterol contents were over 2000μg/g and β-sitosterol was the most predominant sterol in two oils.

Abstract
Lipids account for a high proportion of dietary calories, which greatly affect human health. As a result of differences in composition of fatty acid of individual cooking oils, certain biological effects of these oils may vary. This study aimed to compare postprandial metabolomic profiles of six commonly consumed cooking oils/fats. Adopting a switch-over experimental design ( n = 15), we carried out a human feeding study with six groups (control without oils, soybean oil, olive oil, palm oil, camellia oil, and tallow) and collected fasting and postprandial serum samples. The metabolomic profile was measured by ultra-high-pressure liquid chromatography-quadrupole time of flight. We observed significant differences between the control group and experimental groups for 33 serum metabolites (false discovery rate; p < 0.05), which take part in lipid digestion, fatty acid metabolism, metabolism of pyrimidines and pyrimidine nucleosides, amino acid metabolism, neurobiology, and antioxidation. Sparse partial least squares discriminant analysis revealed distinct metabolomics patterns between monounsaturated fatty acid (MUFA) and saturated fatty acid oils, between soybean oil, olive oil, and palm oil, and between two MUFA-rich oils (olive and camellia oils). The present metabolomics study suggests shared and distinct metabolisms of various cooking oils/fats.

Abstract
BACKGROUND Table olives have been a component of the Mediterranean diet for centuries, with the trend for their consumption currently increasing worldwide. They are rich in bioactive molecules with nutritional, antioxidant, anti-inflammatory or hormone-like properties. In the present study, the concentrations of phenolics, triterpenic acids, carotenoids and vitamins, as well as fatty acid profiles and antioxidant activity, were analyzed in the edible portion of black table olives (Olea europea L.) from Italian (Cellina di Nardò and Leccino) and Greek (Kalamàta and Conservolea) cultivars fermented with selected autochthonous starters and in the corresponding monovarietal olive oils. RESULTS On a fresh weight basis, Cellina di Nardò and Leccino table olives showed the highest total phenolic content. No significant differences were found with respect to the levels of total triterpenic (maslinic and oleanolic) acids and vitamin E among cultivars. All table olives were characterized by high amounts of oleic, linoleic and palmitic acids. Oils were richer in lipophilic antioxidants (carotenoids and tocochromanols) than table olives, which, instead, showed a higher content of polyphenols and triterpenic acids than oils. CONCLUSION The present study demonstrates that fermented table olives are an excellent natural source of unsaturated fatty acids, as well as being nutritionally important health-promoting bioactive compounds. © 2017 Society of Chemical Industry.

The latter have already shown a wide spectrum of in vitro, and ex vivo biologicalactivities including antioxidant, anti-inflammatory, anti-diabetic, antihypertensive, anti-hypercholesterolemia, analgesic, antimicrobial, molluscicidal anti-nociceptive and anticancer potential. Argan flesh (pulp) contains a broad spectrum of polyphenolic compounds which may have utility for incorporation into nutraceuticals and cosmeceuticals relevant to the food, cosmetic and health industries. Further research is recommended, especially on the health beneficial effects of the aminophenols.

Apolipoprotein A2 -265 T>C polymorphism interacts with dietary fatty acids intake to modulate inflammation in type 2 diabetes mellitus patients. Nutrition 2016; 37:86-91. [PMID: 28359369 DOI: 10.1016/j.nut.2016.12.012] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2016] [Revised: 11/01/2016] [Accepted: 12/17/2016] [Indexed: 12/19/2022]
Abstract
OBJECTIVE Several investigations have been conducted regarding the interaction between Apolipoprotein A2 (APOA2) -265 T>C polymorphism and dietary intake of saturated fatty acids (SFAs) on obesity in healthy individuals or type 2 diabetes mellitus (T2 DM) patients. The aim of the present study is to examine the effect of this interaction on inflammatory markers in T2 DM patients. METHODS This is a comparative cross-sectional study on 180 T2 DM patients with known APOA2 genotype. Dietary intake was assessed by food-frequency questionnaire and serum levels of inflammatory markers (interleukin [IL]-18, pentraxin 3, and high-sensitivity C-reactive protein [hs-CRP]) were measured. The subjects were dichotomized into "high" and "low" categories, based on the median dietary intake of polyunsaturated fatty acids (PUFAs), monounsaturated fatty acids (MUFAs), and SFAs. The data were analyzed by analysis of covariance multivariate interaction model. RESULTS In CC genotype, higher median intake of ω-3 PUFAs and MUFAs was associated with decreased serum levels of IL-18 and hs-CRP (P = 0.014 and 0.008, respectively). In T-allele carriers, higher median intake of SFAs was associated with increased serum hs-CRP level (P < 0.001). There was a significant relationship between APOA2 polymorphism and ω-3 PUFA intake on serum IL-18 level (P interaction = 0.03). Moreover, the relationship between this polymorphism and SFA and MUFA intake on serum hs-CRP level was statistically significant (P interaction = 0.03 and 0.024, respectively). CONCLUSIONS In T2 DM patients, the dietary intake of antiinflammatory fatty acids, such as ω-3 PUFAs and MUFAs, could reduce the inflammatory effects associated with the CC genotype. In addition, proinflammatory fatty acids, such as SFAs, could overcome the antiinflammatory effect of the T-allele. Further studies are needed to confirm these findings.

Abstract
Although the beneficial role of Extra Virgin Olive Oil (EVOO) in the Mediterranean diet is well-known, its effects on health cannot be attributed solely to oleic acid. In addition to minor components, the presence of other fatty acids (FA), which depend largely on the cultivar among other factors, needs to be considered. The present study examined the effect of chylomicron remnant-like particles (CRLP) enriched in fatty acids of EVOO from 'Chetoui', 'Buidiego', 'Galega', 'Blanqueta', and 'Picual' cultivars on the foam cell formation by THP-1 macrophages. THP-1 cells were incubated with EVOO-CRLP for 24 h. Lipid accumulation in cells was measured by determining intracellular total triacylglycerol (TAG) concentration and FA composition. Intracellular TAG concentrations were higher in cells incubated with 'Chetoui' and 'Blanqueta' CRLP (0.33 ± 0.05 and 0.38 ± 0.07 μmol/mg of protein, respectively) than with 'Buidiego' and 'Picual' CRLP (0.20 ± 0.05 and 0.24 ± 0.06 μmol/mg of protein, respectively). In conclusion, linoleic acid-rich EVOO induced higher TAG incorporation into THP-1 macrophages compared to oleic acid-rich EVOO, the 18:1/18:2 ratio being consistently correlated with intracellular TAG accumulation. The results of this study demonstrated that the differences in EVOO-FA composition may have an important role in foam cell formation.

Abstract
Following the historical dietary recommendations, the substitution of polyunsaturated fatty acids (PUFAs) for saturated fatty acids (SFAs) resulted in a dramatic increase of linoleic acid (LA) in the Western diet. While proatherogenic properties of SFAs have been described, the involvement of LA on the inflammatory process remains controversial. Herein, we evaluated the effects of an excessive LA intake on the cytokine-induced expression of endothelial adhesion molecules vascular cell adhesion molecule-1 (VCAM-1) and intercellular cell adhesion molecule-1 (ICAM-1), through the nuclear factor (NF)-κB pathway, in comparison with a control diet and regarding a "positive" SFA diet. Wistar rats were fed experimental diets - a control diet or diets enriched with LA or SFA - for 11 weeks. Plasma lipid parameters and proinflammatory cytokine production such as interleukin-1β and tumor necrosis factor (TNF)-α were analyzed. Expression of endothelial adhesion molecules and NF-κB was determined by immunohistochemical analysis. No difference was observed in body weight. The enriched diets did not affect triglyceride and total cholesterol levels in plasma. Our results demonstrated that excessive dietary LA intake increased TNF-α levels (P<.05) in plasma. Rats fed the LA-enriched diet showed a significantly higher expression of VCAM-1, ICAM-1 and NF-κB in aortas. In addition, our results demonstrated that an excess of LA is more efficient to activate endothelial molecular process than an excess of SFA. The present study provides further support for the proinflammatory properties of LA and suggests an LA-derivatives pathway involved in the inflammatory process.

Abstract
The effects of replacing dietary saturated fat by different monounsaturated fatty acid (ω-9MUFA) sources on serum lipids, body fat and bone in growing hypercholesterolemic rats were studied. Rats received one of the six different diets: AIN-93G (control, C); extra virgin olive oil (OO) + C; high-oleic sunflower oil (HOSO) + C or atherogenic diet (AT) for 8 weeks; the remaining two groups received AT for 3 weeks and then, the saturated fat was replaced by an oil mixture of soybean oil added with OO or HOSO for 5 weeks. Rats consuming MUFA-rich diets showed the highest body fat, hepatic index and epididymal, intestinal and perirenal fat, and triglycerides. T-chol and non-HDL-chol were increased in HOSO rats but decreased in OO rats. Bone mineral content and density were higher in both OO and HOSO groups than in AT rats. This study casts caution to the generalization of the benefits of MUFA for the treatment of hypercholesterolemia.

Abstract
OBJECTIVE To evaluate the effects of acute and daily consumption of high-oleic peanuts (HOP) on inflammation and glucose homeostasis in overweight/obese men. METHODS In a 4-week randomized clinical trial, males with body mass index of 29.8 ± 2.3 kg/m(2) and aged 18-50 years were assigned to the groups: control (CT, n = 22); conventional peanuts (CVP, n = 22); or HOP (n = 21). They followed a hypocaloric-diet with or without 56 g/day of CVP or HOP. Main outcomes were changes in fasting blood biomarkers and postprandial insulin, glucose, tumor necrosis factor-alfa (TNF-α), and interleukin-10 (IL-10) responses after acute peanut intake. RESULTS At baseline, HOP showed significantly lower postprandial responses of glucose, insulin, and TNF-α than CVP and CT. Changes in fasting blood biomarkers did not differ between groups after the 4-week intervention. However, within groups, total cholesterol decreased in CT, and all groups reduced High-density lipoprotein (HDL-c). Triglycerides were reduced in HOP and CVP. IL-10 increased significantly in all groups while only the CT and CVP showed increased TNF-α after intervention. CONCLUSION Acute high-oleic peanut consumption leads to stronger moderation of postprandial glucose, insulin, and TNF-α concentrations than CVP and control meal intake. Whether daily intake of high-oleic peanuts has additional benefits to CVP remains uncertain.

Abstract
The Mediterranean diet (MD) is considered one of the healthiest dietary models. Many of the characteristic components of the MD have functional features with positive effects on health and wellness. The MD adherence, calculated through various computational scores, can lead to a reduction of the incidence of major diseases (e.g., cancers, metabolic and cardiovascular syndromes, neurodegenerative diseases, type 2 diabetes and allergy). Furthermore, eating habits are the main significant determinants of the microbial multiplicity of the gut, and dietary components influence both microbial populations and their metabolic activities from the early stages of life. For this purpose, we present a study proposal relying on the generation of individual gut microbiota maps from MD-aware children/adolescents. The maps, based on meta-omics approaches, may be considered as new tools, acting as a systems biology-based proof of evidence to evaluate MD effects on gut microbiota homeostasis. Data integration of food metabotypes and gut microbiota “enterotypes” may allow one to interpret MD adherence and its effects on health in a new way, employable for the design of targeted diets and nutraceutical interventions in childcare and clinical management of food-related diseases, whose onset has been significantly shifted early in life.

Abstract
Rapeseed, strawberry and raspberry seed oils are a rich source of polyunsaturated fatty acids and antioxidants such as tocols, bioflavonoids and phytosterols. The aim of the study was to determine changes in the blood lipid profile of rats fed with rapeseed, strawberry and raspberry seed oils and their effects on selected parameters of oxidative status. The experiment was carried out on male Wistar rats. The oils were administered by oral gavage for 5 weeks once daily at the dose of about 0.8 ml per rat. Blood samples were taken before and after supplementation period. The activity of superoxide dismutase (SOD) and glutathione peroxidase (cGPx) was assessed in erythrocytes and contents of triglycerides (TG), total cholesterol, low-density fraction of cholesterol (LDL) and high-density fraction of cholesterol (HDL) were assessed in plasma. The experiment shows that oils supplemented in the diet for 5 weeks had no significant effect on the level of triglyceride (TG), total cholesterol as well as HDL and LDL fractions. Reduced activity of cGPX and SOD in the group of rats receiving raspberry and strawberry seed oils suggests that these native oils may contribute to oxidative stability (improves antioxidant status). Thus, strawberry and raspberry seed oils can be considered as special biological oils, which constitute potential nutraceuticals reducing oxidative stress.

Abstract
Over 50 years of research has sought to define the role dietary fat plays in cardiovascular disease (CVD) risk. Although optimal dietary fat quantity has been keenly pursued over past decades, attention has recently centered on the value of dietary fat quality. The purpose of the present review is to provide a critical assessment of the current body of evidence surrounding efficacy of dietary monounsaturated fatty acids (MUFA) for reduction of traditional risk factors defining metabolic syndrome (MetS) and CVD. Due to existing and emerging research on health attributes of MUFA rich diets, and to the low prevalence of chronic disease in populations consuming MUFA rich Mediterranean diets, national dietary guidelines are increasingly recommending dietary MUFA, primarily at the expense of saturated fatty acids (SFA). Consumption of dietary MUFA promotes healthy blood lipid profiles, mediates blood pressure, improves insulin sensitivity and regulates glucose levels. Moreover, provocative newer data suggest a role for preferential oxidation and metabolism of dietary MUFA, influencing body composition and ameliorating the risk of obesity. Mounting epidemiological and human clinical trial data continue to demonstrate the cardioprotective activity of the MUFA content of dietary fat. As the debate on the optimal fatty acid composition of the diet continues, the benefit of increasing MUFA intakes, particularly as a substitute for dietary SFA, deserves considerable attention.

Abstract
In parenteral nutrition (PN), essential fatty acids are provided by soy oil‐based fat emulsions, which may exert adverse effects on the immune system and lipid peroxidation. Olive oil ‐based fat emulsions have been said to prevent these undesired effects. This study compares effects of olive oil ‐ and soy oil ‐based fat emulsions in 22 patients who underwent abdominal surgery for cancer. The first group (n = 10) received soy oil ‐based fat emulsion; the second group (n = 10) received olive oil ‐based fat emulsion. Body temperature, body mass index, (BMI) and biochemical variables were measured on days 0 and 7. There were no differences between the groups with regard to BMI or temperature. On day 7, the first group (compared with day 0) had significant increases in plasma alkaline phosphatase (81.70 ± 16.03 vs 117.60 ± 11.1), γ‐glutamyl transferase (39.90 ± 15.40 vs 137.70 ± 24.09), and mean body temperature (36.72°C ± 0.14°C vs 37.20°C ± 0.17°C) (P < .01). Second group had increases in alkaline phosphatase (85.80 ± 13.46 vs 147.20 ± 34.17), γ‐glutamyl transferase (48.40 ± 12.86 vs 129.40 ± 42.03), total protein (5.14 ± 0.19 vs 6.06 ± 0.49), and albumin (2.62 ± 0.14 vs 3.00 ± 0.18) (P < .05). Changes in thiobutyric acid levels were not statistically significant in either group. In postoperative cancer patients, olive oil‐based fat emulsion had similar effects on BMI, body temperature, biochemical values, and thiobutyric acid levels as soy oil‐based fat emulsions.

Ischemic heart disease is the leading cause of mortality worldwide. Many mechanistic reasons support that a high consumption of olive oil may provide a protection against myocardial infarction, the hallmark of ischemic heart disease. International comparisons are also consistent with this hypothesis. Surprisingly, there is not much evidence coming from analytical epidemiological studies about this issue. A case-control study conducted at the University of Navarra (Spain) found a strong inverse association between olive oil consumption and the risk of a first non-fatal myocardial infarction. Subsequently a large cohort in Italy and another case-control study conducted in Greece also found inverse associations. However, no complete consistency exists and further prospective studies and trials are being implemented in order to obtain more complete evidence.

Abstract
The physiological and pathological role of oxidized polyunsaturated fatty acids (PUFAs) has been extensively studied, whereas those of hydroxy monounsaturated fatty acids (MUFAs) are not well understood. This study demonstrated that 11-hydroxy-(9Z)-octadecenoic acid ((9Z)-11-HOE), which was isolated from adlay seeds (Coix lacryma-jobi L. var. ma-yuen STAF.), can activate peroxisome proliferator-activated receptor (PPAR)alpha, delta and gamma in luciferase reporter assays more efficiently than (9Z)-octadecenoic acid (oleic acid), and to the same degree as linoleic acid. (9Z)-11-HOE increased the mRNA levels of UCP2 and CD36 in C2C12 myotubes and THP- 1 cells, respectively, and these effects were blocked by the PPARdelta- and gamma-specific antagonists GSK0660 and T0070907, respectively. Evaluation of the structure.activity relationship between hydroxy MUFAs and PPAR activation revealed that (9E)-11-HOE, the geometrical isomer of (9Z)-11-HOE, activated PPARs more potently than (9Z)-11-HOE, and that PPAR activation by hydroxyl MUFAs was not markedly influenced by the position of the hydroxy group or the double bond, although PPARdelta seemed to possess ligand specificity different to that of PPARalpha or gamma . Additionally, the finding that 11-hydroxy octadecanoic acid, the hydrogenated product of (9E)-11- HOE, was also capable of activating PPARs to a similar extent as (9E)-11-HOE indicates that the double bond in hydroxy MUFAs is not essential for PPAR activation. In conclusion, (9Z)-11-HOE derived from alday seeds and hydroxy MUFAs with a chain length of 16 or 18 acted as PPAR agonists. Hydroxylation of MUFAs may change these compounds from silent PPAR ligands to active PPAR agonists.

Abstract
A functional oil containing diacylglycerol (DAG) and monoacylglycerol (MAG) has been shown to have a strong anti-atherosclerotic effect in a mouse model. Among the lipid components, MAG is responsible for the beneficial effect with an enhanced antioxidant effect in the mouse model. In this report, several MAG-containing fatty acids (MAG-oleic acid [MAG-O], MAG-palmitic acid [MAG-P], and MAG-stearic acid [MAG-S]) were synthesized, and the antioxidant and anti-atherogenic activities were evaluated in vitro and in a cellular model. MAG-O had the strongest radical scavenging and antioxidant activities against copper-mediated low-density lipoprotein (LDL) oxidation and the strongest inhibitory activity against LDL-associated phospholipase A(2) and exhibited potent activation of paraoxonase activity, which contributes to the maintenance of antioxidant activity. All MAG species in this study exhibited inhibitory activity against glycation of apolipoproteins, in contrast to DAG. Oxidized LDL uptake into THP-1 cells was strongly inhibited by MAG-O treatment at a final concentration of 20 microM. MAG-O-treated cell culture medium showed the lowest production of malondialdehyde and lipid hydroperoxide compared to MAG-S and MAG-P. In conclusion, MAG-O had potent antioxidant, antidiabetic, and anti-atherogenic effects in vitro and in a cellular model.

Abstract
The main objective of this study was to evaluate in vivo whether micronutrient-enriched high-oleic sunflower oils (optimized oils) obtained using different crushing and refining procedures could have any beneficial effect on plasma lipid profile and antioxidant status. Sprague-Dawley rats were fed a high-fat diet for 4 weeks. The lipid source consisted of 20% optimized sunflower oils with different quantities and qualities of micronutrients. The control group received traditional refined high-oleic sunflower oil. The experimental optimized oils in the diets had a hypolipidemic effect. The reduction in plasma triglyceride and total cholesterol levels was 43% and 20%, respectively, in the group fed the diet with the highest levels of micronutrients. The serum ferric antioxidant capacity, superoxide dismutase, glutathione peroxidase and reduced glutathione significantly increased and lipid peroxidation decreased in parallel with the enhancement of micronutrients. These results suggest that a regular intake of optimized sunflower oils can help to improve lipid status and reduce lipid peroxidation in plasma.

Abstract
Diet is associated with the development of CHD. The incidence of CHD is lower in southern European countries than in northern European countries and it has been proposed that this difference may be a result of diet. The traditional Mediterranean diet emphasises a high intake of fruits, vegetables, bread, other forms of cereals, potatoes, beans, nuts and seeds. It includes olive oil as a major fat source and dairy products, fish and poultry are consumed in low to moderate amounts. Many observational studies have shown that the Mediterranean diet is associated with reduced risk of CHD, and this result has been confirmed by meta-analysis, while a single randomised controlled trial, the Lyon Diet Heart study, has shown a reduction in CHD risk in subjects following the Mediterranean diet in the secondary prevention setting. However, it is uncertain whether the benefits of the Mediterranean diet are transferable to other non-Mediterranean populations and whether the effects of the Mediterranean diet will still be feasible in light of the changes in pharmacological therapy seen in patients with CHD since the Lyon Diet Heart study was conducted. Further randomised controlled trials are required and if the risk-reducing effect is confirmed then the best methods to effectively deliver this public health message worldwide need to be considered.

Abstract
OBJECTIVE To assess the adherence to the Mediterranean dietary pattern in the population from a coastal region from north-east Spain and its relationship to diseases, applying the Mediterranean Diet Quality Index (M-DQI) validated by the use of several biomarkers. DESIGN Cross-sectional nutrition survey. SETTING Population-based random sample derived from the Catalan Nutrition Survey. SUBJECTS A total of 621 healthy adults. RESULTS The Catalan representative sample presented a mean M-DQI score of 6.6 (sd 2.3, median 7, range 0-14). The percentage of adherence to the Mediterranean diet was 53 %; 10 % of subjects showed high adherence to the Mediterranean diet, while only 2 % were categorized as poorest adherence. The plasma fatty acid profile of the Catalan sample progressed with perfect regularity throughout the index ranges. Both EPA and DHA presented a significant correlation to the M-DQI (r = -0.410 for EPA and -0.360 for DHA). A significant increase in palmitic, oleic and alpha-linolenic acids and a significant decrease in stearic, linoleic and arachidonic acids content were also observed. The mean values for the M-DQI according to the clinical characteristics of the Catalan sample were also calculated. CONCLUSIONS The M-DQI has been demonstrated a suitable tool for assessment of an individual's nutritional status according to the Mediterranean dietary pattern and for clinical purposes. Although the current diet followed in Catalonia seems to agree with the main characteristics of the Mediterranean diet, the promotion of the Mediterranean pattern should be reinforced in the Catalan population, especially among young people.

Abstract
The clinical implications of non-alcoholic fatty liver diseases (NAFLD) derive from their potential to progress to fibrosis and cirrhosis. Inappropriate dietary fat intake, excessive intake of soft drinks, insulin resistance and increased oxidative stress results in increased free fatty acid delivery to the liver and increased hepatic triglyceride (TG) accumulation. An olive oil-rich diet decreases accumulation of TGs in the liver, improves postprandial TGs, glucose and glucagon-like peptide-1 responses in insulin-resistant subjects, and upregulates glucose transporter-2 expression in the liver. The principal mechanisms include: decreased nuclear factor-kappaB activation, decreased low-density lipoprotein oxidation, and improved insulin resistance by reduced production of inflammatory cytokines (tumor necrosis factor, interleukin-6) and improvement of jun N-terminal kinase-mediated phosphorylation of insulin receptor substrate-1. The beneficial effect of the Mediterranean diet is derived from monounsaturated fatty acids, mainly from olive oil. In this review, we describe the dietary sources of the monounsaturated fatty acids, the composition of olive oil, dietary fats and their relationship to insulin resistance and postprandial lipid and glucose responses in non-alcoholic steatohepatitis, clinical and experimental studies that assess the relationship between olive oil and NAFLD, and the mechanism by which olive oil ameliorates fatty liver, and we discuss future perspectives.

Abstract
This review focuses on the relationships among dietary fat type, plasma and liver lipid, and lipoprotein metabolism and atherosclerosis. Dietary polyunsaturated fatty acids are beneficial for the prevention of coronary artery atherosclerosis. By contrast, dietary monounsaturated fatty acids appear to alter hepatic lipoprotein metabolism, promote cholesteryl oleate accumulation, and confer atherogenic properties to lipoproteins as shown in data from experimental animal studies. Polyunsaturated fat appears to provide atheroprotection, at least in part, because it limits the accumulation of cholesteryl oleate in favor of cholesteryl linoleate in plasma lipoproteins.

Abstract
BACKGROUND Inflammation is crucial in all stages of atherosclerosis, and few studies have investigated the effect of dietary fat on markers of inflammation related to this disease during the postprandial period. OBJECTIVE To evaluate the chronic effects of dietary fat on the postprandial expression of proinflammatory genes in peripheral blood mononuclear cells (PBMCs) in healthy subjects. DESIGN 20 healthy men followed three different diets for 4 weeks each, according to a randomized crossover design: Western diet: 15% protein, 47% carbohydrates (CHO), 38% fat (22% saturated fatty acid (SFA)); Mediterranean diet: 15% protein, 47% CHO, 38% fat (24% monounsaturated fatty acid (MUFA)); CHO-rich and n-3 diet: 15% protein, 55% CHO, <30% fat (8% polyunsaturated fatty acid (PUFA)). After 12-h fast, volunteers were given a breakfast with a fat composition similar to that consumed in each of the diets-butter breakfast: 35% SFA; olive oil breakfast: 36% MUFA; walnut breakfast: 16% PUFA, 4% alpha-linolenic acid (LNA). RESULTS The butter breakfast induced a higher increase in tumor necrosis factor (TNF)-alpha messenger RNA (mRNA) expression than the olive oil or walnut breakfasts (P=0.014) in PBMCs. Moreover, we found a higher postprandial response in the mRNA of interleukin (IL)-6 with the intake of butter and olive oil breakfasts than with the walnut breakfast (P=0.025) in these cells. However, the effects of the three fatty breakfasts on the plasma concentrations of these proinflammatory parameters showed no significant differences (P=N.S.). CONCLUSION Consumption of a butter-enriched meal elicits greater postprandial expression of proinflammatory cytokine mRNA in PBMCs, compared to the olive oil and walnut breakfasts.

Abstract
OBJECTIVE To assess the relation between adherence to a Mediterranean diet and the incidence of diabetes among initially healthy participants. DESIGN Prospective cohort study with estimates of relative risk adjusted for sex, age, years of university education, total energy intake, body mass index, physical activity, sedentary habits, smoking, family history of diabetes, and personal history of hypertension. SETTING Spanish university department. PARTICIPANTS 13 380 Spanish university graduates without diabetes at baseline followed up for a median of 4.4 years. MAIN OUTCOME MEASURES Dietary habits assessed at baseline with a validated 136 item food frequency questionnaire and scored on a nine point index. New cases of diabetes confirmed through medical reports and an additional detailed questionnaire posted to those who self reported a new diagnosis of diabetes by a doctor during follow-up. Confirmed cases of type 2 diabetes. RESULTS Participants who adhered closely to a Mediterranean diet had a lower risk of diabetes. The incidence rate ratios adjusted for sex and age were 0.41 (95% confidence interval 0.19 to 0.87) for those with moderate adherence (score 3-6) and 0.17 (0.04 to 0.75) for those with the highest adherence (score 7-9) compared with those with low adherence (score <3). In the fully adjusted analyses the results were similar. A two point increase in the score was associated with a 35% relative reduction in the risk of diabetes (incidence rate ratio 0.65, 0.44 to 0.95), with a significant inverse linear trend (P=0.04) in the multivariate analysis. CONCLUSION Adherence to a Mediterranean diet is associated with a reduced risk of diabetes.

Abstract
We investigated the effects of high-monounsaturated fatty acid (MUFA) versus high-carbohydrate enteral formula on post-prandial plasma glucose concentration and insulin response in Japanese patients with type 2 diabetes mellitus and healthy Japanese volunteers. Ten healthy volunteers aged 20.8 +/- 1.2 years and 12 diabetic patients with good glycaemic control (glycosylated haemoglobulin < 7%) aged 58.6 +/- 7.7 years were randomly assigned to take high-MUFA or high-carbohydrate formula after a 12-h overnight fast. The patients switched to the other formula after 7 days. Post-prandial plasma glucose and insulin response were significantly lower in all subjects after taking high-MUFA formula compared with high-carbohydrate formula. No differences were observed in free fatty acids, triglycerides and plasma glucagon between the two diet groups. In conclusion, a high-MUFA enteral formula suppresses post-prandial hyperglycaemia without exaggerated insulin secretion compared with a high-carbohydrate enteral diet in patients with type 2 diabetes and healthy subjects.

Abstract
OBJECTIVE The purpose of this ancillary study is to determine the quality of diets in patients with documented coronary heart disease (CHD). DESIGN Dietary data were originally collected using a 24-hour dietary recall in 555 patients with CHD, 1 year after a diagnostic coronary angiography. Data used for this investigation were collected between March 2001 and November 2003. SUBJECTS/SETTING Patients were participants in a clinical trial to improve adherence to lipid-lowering medications. The Alternate Healthy Eating Index, an instrument designed to evaluate the degree to which a diet has the potential to prevent cardiovascular disease, measured dietary quality. MAIN OUTCOME MEASURES Linear regression models were used to assess the association of dietary quality with patients' sociodemographic and clinical characteristics. RESULTS Mean age of participants was 61 years, with an average body mass index of 30 (calculated as kg/m(2)). Sixty percent were men. Average daily caloric intake was 1,775 kcal, with 50% of calories derived from carbohydrates, 18% from protein, and 32% from total fat. Average Alternate Healthy Eating Index score was 30.8 out of a possible maximum score of 80. Only 12.4% of subjects met the recommended consumption of vegetables, 7.8% for fruit, 8% for cereal fiber, and 5.2% for trans-fat intake. Lower dietary quality was associated with lower total caloric intake, as well as with smoking, obesity, and lower educational level. CONCLUSIONS A high proportion of patients reported poor dietary quality 1 year after experiencing a coronary event. Our data support continued efforts to enhance healthful dietary changes over time for secondary prevention of CHD. Dietary change should be emphasized with CHD patients who are less educated, smokers, or obese.

Abstract
BACKGROUND Hemostasis is the result of a complex equilibrium between coagulation and fibrinolysis, and the influence of different dietary models on this equilibrium is not entirely known. OBJECTIVE The objective was to compare the effects of the chronic intake of different dietary models on postprandial hemostasis. DESIGN In a randomized crossover design, 20 healthy men consumed for 28 d each diets rich in monounsaturated fatty acids (MUFAs), saturated fatty acids (SFAs), and carbohydrates plus n-3 fatty acids (CHO/N3). Fasting and postprandial hemostatic factors (factor VII coagulant activity, plasminogen activator inhibitor-1, tissue-type plasminogen activator, d-dimer, and thromboxane B(2)) were measured; meal tests for the postprandial measures were based on butter, virgin olive oil, and walnuts for the SFA, MUFA, and CHO/N3 diets, respectively. RESULTS There were no differences in the fasting variables after the dietary periods. After the 3 fatty meals were consumed, we observed an increase in thromboxane B(2) and d-dimer and a reduction in tissue plasminogen activator, irrespective of the dietary model. The MUFA or CHO/N3 meals lowered postprandial concentrations of factor VII coagulant activity, although the reduction was greater after the MUFA-enriched meal. The concentration of plasminogen activator inhibitor-1 was greater after the SFA meal than after the other 2 meals. CONCLUSIONS The administration of a fatty meal induces a postprandial procoagulant tendency, irrespective of the type of fat consumed. However, the use of a dietary model rich in SFA creates a more procoagulant environment than does a model that includes MUFA or CHO/N3 as the source of fatty acids.

Abstract
Interest in the Mediterranean diet (MD) has grown worldwide due to its link with greater longevity and lower cardiovascular disease rate, cancer and age cognitive decline. Despite the high complexity of its nutrients composition, olive oil emerges as its principal food, since it provides the higher percent of energy and a lot of bioactive compounds. In this review we will discuss the benefits of diets enriched in virgin olive oil, whose effects are probably due not only to its oleic acid content but also to its other potentially health-promoting components. Traditionally, the benefits of MD were linked to its effect on lipoprotein metabolism but today we realise that there exists a whole sheaf of other benefits, including the components of haemostasis: platelet function, thrombogenesis and fibrinolysis. A diet enriched in virgin olive oil can reduce the sensitivity of platelets to aggregation, decreasing von Willebrand and tromboxane B2 plasma levels. Moreover a particular interest has arisen about its capacity to decrease fasting Factor VII plasma levels and to avoid or modulate its postprandial activation. Also Tissue Factor expression in mononuclear cells could be reduced with the chronic intake of virgin olive oil and finally, studies performed in different experimental situation have shown that it could also increase fibrinolytic activity, reducing plasma concentration of Plasma Activator Inhibitor type-1.

Abstract
Olive oil is the most representative food in the traditional Mediterranean diet and its most important source of MUFA. The healthy benefits of MUFA-rich diets on plasma cholesterol levels, were the first to generate interest in this dietary model. In addition to the benefits conferred by its lipids, olive oil has other biological effects, some of them also related to MUFA. However, most recent studies have shown that there are a number of properties that depend on, or are potentiated by, the consumption of olive oil, such as virgin olive oil, that is rich in microcomponents. This foodstuff, thanks to its double set of benefits, thus tends to produce a better lipid profile and a less prothrombotic environment, promoting antioxidant and anti-inflammatory effects, with a greater endothelial protective capacity. In view of these effects, it would appear that when olive oil is the basic source of dietary alimentary fat it has a major antiatherogenic capacity, which is not shared to the same extent by other oils that are rich in oleic acid but lack its characteristic micronutrients.

Abstract
Olive oil decreases the risk of CVD. This effect may be due to the fatty acid profile of the oil, but it may also be due to its antioxidant content which differs depending on the type of olive oil. In this study, the concentrations of oleic acid and antioxidants (phenolic compounds and vitamin E) in plasma and LDL were compared after consumption of three similar olive oils, but with differences in their phenolic content. Thirty healthy volunteers participated in a placebo-controlled, double-blind, crossover, randomized supplementation trial. Virgin, common, and refined olive oils were administered during three periods of 3 weeks separated by a 2-week washout period. Participants were requested to ingest a daily dose of 25 ml raw olive oil, distributed over the three meals of the day, during intervention periods. All three olive oils caused an increase in plasma and LDL oleic acid (P < 0·05) content. Olive oils rich in phenolic compounds led to an increase in phenolic compounds in LDL (P < 0·005). The concentration of phenolic compounds in LDL was directly correlated with the phenolic concentration in the olive oils. The increase in the phenolic content of LDL could account for the increase of the resistance of LDL to oxidation, and the decrease of thein vivooxidized LDL, observed in the frame of this trial. Our results support the hypothesis that a daily intake of virgin olive oil promotes protective LDL changes ahead of its oxidation.

Abstract
Popular weight-loss plans often have conflicting recommendations, which makes it difficult to determine the most healthful approach to weight loss. Our study compares the dietary quality of popular weight-loss plans. Dietary quality, measured by the Alternate Healthy Eating Index (AHEI), was calculated via sample menus provided in published media for the New Glucose Revolution, Weight Watchers, Atkins, South Beach, Zone, Ornish, and 2005 US Department of Agriculture Food Guide Pyramid (2005 Food Guide Pyramid) plans. The criterion for determining which weight-loss plans were the most popular was their status on the New York Times Bestseller list. Weight Watchers and the 2005 Food Guide Pyramid plan were included because they are the largest commercial weight-loss plan, and the current government recommendation, respectively. Analysis of variance was used to compare nutrient information among the weight-loss plans. The AHEI scores adjusted for energy content were also compared. Of a maximum possible score of 70, the AHEI scores for each weight-loss plan from the highest to the lowest plan were: Ornish (score 64.6), Weight Watchers high-carbohydrate (score 57.4), New Glucose Revolution (score 57.2), South Beach/Phase 2 (score 50.7), Zone (score 49.8), 2005 Food Guide Pyramid (score 48.7), Weight Watchers high-protein (score 47.3), Atkins/100-g carbohydrate (score 46), South Beach/Phase 3 (score 45.6), and Atkins/45-g carbohydrate (score 42.3). Dietary quality varied across popular weight-loss plans. Ornish, Weight Watchers high-carbohydrate, and New Glucose Revolution weight-loss plans have an increased capacity for cardiovascular disease prevention when assessed by the AHEI.
