OBJECTIVE:The independent effects of acute endurance exercise on FGF21 metabolism are poorly understood. Therefore, the purpose of this study was to determine whether acute endurance exercise modulates serum postprandial FGF21 levels in an age-dependent manner.

DESIGN:Exercise intervention trial.

PATIENTS:Twenty-eight subjects participated in the experiment, of whom 13 were excluded mainly because of a serum FGF21 level below the limit of detection. Thus data from 7 young (age: 18-22 years) and 8 elderly male subjects (age: 62-69 years) were analysed.

MEASUREMENTS:Participants were asked to perform a cycling exercise for 30 min at 70% maximal oxygen uptake, following carbohydrate intake. Blood samples were collected pre-exercise and 0 min, 30 min, 1 h, 3 h, and 24 h after the cessation of exercise. Serum FGF21 levels were measured by an enzyme linked immunosorbent assay.

RESULTS:Higher serum FGF21 was observed in the elderly subjects group throughout the experiment (p<0.05). There was no significant increase in serum FGF21 levels after the cessation of exercise, whereas serum FGF21 levels were significantly lower 24 h after the exercise compared with those pre-exercise, 0 min, 30 min, and 1 h after the cessation of exercise in both groups (p<0.01). The response did not differ between the two groups because of no significant group× time interaction.

CONCLUSIONS:Acute endurance exercise lowers serum FGF21 levels 24 hours following exercise. The results suggest that acute endurance exercise modulates postprandial FGF21 metabolism regardless of age. This article is protected by copyright. All rights reserved.

The purpose of this experiment was to evaluate the potential combined effects of acute exercise and mindfulness mediation on episodic memory.All data collection occurred in the authors' laboratory (January to May of 2019). In this three-arm, within-subject design, participants (N=20; M=21.6 years) completed three counterbalanced laboratory visits, including Exercise Only, Exercise + Meditation and Control. Learning and memory were assessed from a word-list task. A one-factor repeated-measures ANOVA was computed for two memory outcomes, including the learning outcome (average performance across the 6 trials) and the long-term memory recall (10-minute delay).The exercise conditions had a greater learning effect when compared to the Control visit, M= 0.68 (95% CI: 0.10, 1.25), P = 0.02. The Exercise + Memory visit had better longterm memory when compared to Exercise Only, M= 0.95 (95% CI: 0.07, 1.83), P = 0.03.The present experiment provides suggestive evidence that acute exercise may enhance learning and, when coupling acute exercise prior to encoding with meditation during early consolidation, long-term memory may be enhanced.

Numerous methods have been used to minimize the cardiotoxic effects of the chemotherapeutic agent doxorubicin (DOX), and most have had limited success. Chronic endurance exercise has been shown to protect against DOX cardiotoxicity, but little is known regarding the effects of acute exercise on DOX-induced cardiac dysfunction.

PURPOSE: The purpose of this study was to determine the effects of a single bout of acute endurance exercise on the cardiac dysfunction associated with DOX treatment.

METHODS: Male Sprague-Dawley rats either performed an acute exercise bout on a motorized treadmill for 60 minutes at a maximal speed of 25 m/min with a 5% grade (EX) or remained sedentary (SED) 24 hours before receiving either a 15-mg/kg DOX bolus dose or saline (SAL). Cardiac function was then analyzed 5 days post injection using a Langendorff isolated perfused heart model. In addition, myocardial lipid peroxidation was analyzed as an indicator of oxidative stress.

RESULTS: Doxorubicin treatment alone (SED+DOX) promoted a significant decline in end-systolic pressure (-35%), left ventricular developed pressure (-59%), and the maximal rate of left ventricular pressure development (-43%) as well as a 45% increase in lipid peroxidation products when compared with SED+SAL (P<.05). Acute exercise 24 hours before DOX treatment, however, had a cardioprotective effect, as end-systolic pressure, left ventricular developed pressure, and the maximal rate of left ventricular pressure development were significantly higher in EX+DOX compared with SED+DOX (P<.05) and EX+DOX had similar levels of lipid peroxidation products as SED+SAL

CONCLUSIONS: An acute exercise bout performed 24 hours before DOX treatment protected against cardiac dysfunction, and this exercise-induced cardioprotection may partly be explained by a reduction in the generation of reactive oxygen species.

Dietary nitrate (NO3-) is converted to nitrite (NO2-) and can be further reduced to the vasodilator nitric oxide (NO) amid a low Oenvironment. Accordingly, dietary NO3- increases hind limb blood flow in rats during treadmill exercise; however, the evidence of such an effect in humans is unclear. We tested the hypothesis that acute dietary NO3- (via beetroot [BR] juice) increases forearm blood flow (FBF) via local vasodilation during handgrip exercise in young adults (n = 11; 25 ± 2 years). FBF (Doppler ultrasound) and blood pressure (Finapres) were measured at rest and during graded handgrip exercise at 5%, 15%, and 25% maximal voluntary contraction (MVC) lasting 4 min each. At the highest workload (25% MVC), systemic hypoxia (80% SaO) was induced and exercise continued for three additional minutes. Subjects ingested concentrated BR (12.6 mmol nitrate (n = 5) or 16.8 mmol nitrate (n = 6) and repeated the exercise bout either 2 (12.6 mmol) or 3 h (16.8 mmol) postconsumption. Compared to control, BR significantly increased FBF at 15% MVC (184 ± 15 vs. 164 ± 15 mL/min), 25% MVC (323 ± 27 vs. 286 ± 28 mL/min), and25% + hypoxia (373 ± 39 vs. 343 ± 32 mL/min) and this was due to increases in vascular conductance (i.e., vasodilation). The effect of BR on hemodynamics was not different between the two doses of BR ingested. Forearm VOwas also elevated during exercise at 15% and 25% MVC. We conclude that acute increases in circulating NO3- and NO2- via BR increases muscle blood flow during moderate- to high-intensity handgrip exercise via local vasodilation. These findings may have important implications for aging and diseased populations that demonstrate impaired muscle perfusion and exercise intolerance.

Acute physical activity of moderate to vigorous intensity has been shown to improve cognitive functions in children. However, the empirical evidence associated with Attention Deficit Hyperactivity Disorder (ADHD) in children is still limited, in particular regarding which specific cognitive functions benefit. This study investigated the effects of an acute bout of physical activity on multiple aspects of executive functions (inhibition, switching, and visual working memory) in children with ADHD. Forty-six children (8-12 years old; 82.6% boys) were randomly assigned to either 15 minutes of acute exergaming (physical activity of moderate intensity) or to a control condition (sedentary). Executive function performance in inhibition, switching and visual working memory were assessed before and after each condition, using a modified version of both the Flanker and the ColorSpan Backwards Task. The results revealed that participants in the exergaming group performed significantly faster than those in the control group in terms of both inhibition and switching, but there was no significant difference in the accuracy of the two tasks nor in visual working memory performance. These findings suggest that acute physical activity utilizing exergaming has the potential to improve specific aspects of executive functions (reaction times in inhibition and switching) in children with ADHD.

Qigong is a gentle exercise that promotes health and well-being. This study evaluated the acute physiological and psychological effects of one session of qigong exercise in older practitioners. A total of 45 participants (mean age, 65.14 years) were recruited. Meridian electrical conductance, State-Trait Anxiety Inventory (STAI), heart rate variability (HRV), and Short Form 36 (SF-36) were evaluated and compared before and after one session of qigong exercise. The results revealed that the electrical conductance of all meridians, except spleen and bladder meridians, increased significantly (<0.05). Compared with baseline values, upper to lower body ratio and sympathetic/vagal index were significantly improved and closer to 1 (= 0.011 and= 0.007, resp.). STAI-S and STAI-T scores decreased significantly (<0.001 and= 0.001, resp.). The RR interval of HRV decreased significantly (= 0.035), a significant positive correlation was observed between kidney meridian electrical conductance and SF-36 physical scores (= 0.74,= 0.018), and a positive correlation was observed between pericardium meridian electrical conductance and SF-36 mental scores (= 0.50,= 0.06). In conclusion, one session of qigong exercise increased meridian electrical conductance, reduced anxiety, and improved body and autonomic nervous system balance. These findings provide scientific evidence for acute physiological and psychological effects of qigong exercise in older practitioners.

We studied the effects of a 2-day walk exercise (6 h+6 h) on the serum concentration of circulating moderately oxidized LDL (LDL baseline conjugated dienes), lipids (total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride), antioxidants (alpha-tocopherol, gamma-tocopherol, beta-carotene, and ubiquinol-10), and antioxidant potential in serum (S-TRAP) and LDL (LDL-TRAP) in healthy well-trained men. The exercise was performed twice with an interval of 14 days. While 6 h walking the subjects drank 6 cl . kg (-1) water which contained either carbohydrate (CHO trial) or placebo (PLA trial). During the 2-day exercise the level of oxidized LDL decreased by 25 % (p=0.001) in the PLA trial. At the same time serum gamma-tocopherol decreased by 20 % (p=0.049), while the other measured antioxidants remained unchanged and the serum antioxidant potential increased by 22 % (p=0.018). Serum total cholesterol decreased by 3 % (p=0.017), serum triglycerides by 22 % (p=0.001), and LDL-cholesterol by 14 % (p=0.045). HDL cholesterol increased by 9 % (p=0.001). The results in the carbohydrate trial were similar to the ones in the PLA trial. The findings suggest that exercise of long duration but of low, non-exhaustive intensity decreases the concentration of circulating oxidized LDL simultaneously with an increase in serum antioxidant potential in healthy trained men. Carbohydrate ingestion during the exercise does not have any further effect on these changes.

Background:Clinical studies have reported hydrogen-rich water (HRW) to have therapeutic and ergogenic effects. The aim of this study was to determine the effect of acute supplementation with HRW on exercise performance as measured by VO, respiratory exchange ratio (RER), heart rate (HR), and respiratory rate (RR).

Methods:Baseline levels of all exercise indices were determined in nineteen (4 female, 23.4± 9.1 yr; 15 male, 30.5 ± 6.8 yr) healthy subjects using a graded treadmill exercise test to exhaustion. Each subject was examined two additional times in a randomized double-blinded, placebo-controlled crossover fashion. Subjects received either HRW or placebo, which was consumed the day before and the day of the testing. HRW was delivered using the hydrogen-producing tablets, DrinkHRW (5 mg of H). All data was analyzed with SPSS using pairwise comparisons with Bonferroni adjustment.

Results:HRW supplementation did not influence maximal or minimal indices of exercise performance (VO, RER, HR and RR) (p<0.05). However, HRW significantly decreased average exercising RR and HR (p<0.05). HRW decreased exercising HR during minutes 1-9 of the graded exercise test (121± 26 bpm) compared to placebo (126 ± 26 bpm) and baseline (124 ± 27 bpm) (p<0.001) without substantially influencing VO.

Conclusion:Acute supplementation of DrinkHRW tablets may benefit submaximal aerobic exercise performance by lowering exercising HR. Further studies are needed to determine the influence and practical significance of HRW on varying exercise intensities as well as optimal dosing protocols and the effects of chronic use.

OBJECTIVES:This study aimed to characterize the association of lifestyle and nutritional risk profiles with age-related macular degeneration (AMD) in two subpopulations with differing AMD prevalence.

METHODS:This case-control study (n = 1992) included 768 patients with AMD and 1224 age- and sex-matched participants without AMD with a single visit at a primary health care unit. Enrolled participants completed a validated lifestyle and food frequency questionnaire. A score to measure adherence to the Mediterranean diet (mediSCORE; Range, 0-9) was constructed from individual food intakes, which were further analyzed by conversion to nutrient consumption.

RESULTS:Higher adherence to the Mediterranean diet (mediSCORE≥6) was significantly associated with no AMD (odds ratio [OR] = 0.73; P = 0.009). The subpopulation with lower AMD prevalence presented significantly higher adherence to the Mediterranean diet in relation to all individual food groups that comprised the mediSCORE (P < 0.014) with the exception of cereals. Food group analysis showed significant associations between the increased consumption of vegetables (OR = 0.63; P < 0.001) and fruit and nuts (OR = 0.78; P = 0.010) with no AMD. Nutrient analysis revealed that an increased ingestion of water, fibers, total fat, monounsaturated and polyunsaturated fatty acids, linoleic acid, vitamins A and C, carotene, alpha-tocopherol, folate, magnesium, iron, and zincwere significantly associated with no AMD (P < 0.0013). Finally, regular physical activity was associated with no AMD (P = 0.003).

CONCLUSIONS:High adherence to a Mediterranean diet and regular physical activity seem to be protective factors for AMD in a Portuguese population. The effect of the diet is likely driven by the increased consumption of vegetables, fruits, and nuts.

Excessive calorie intake and physical inactivity are considered key determinants of the rapid worldwide increase in obesity prevalence, however the relationship between diet and weight gain is complex. We investigated associations between adherence to a Mediterranean diet and long-term changes in weight and waist circumference in volunteers recruited to the Italian section of the prospective European Prospective Investigation into Cancer and Nutrition (EPIC). We investigated 32,119 cohort members who provided anthropometric measures at recruitment and updated information on recall a mean of 12 years later. Adherence to a Mediterranean diet was assessed using the Italian Mediterranean Index (score range 0-11). Associations between index score and weight and waist changes were assessed by multivariate linear regression models. Risks of developing overweight/obesity and abdominal obesity were investigated by multivariate logistic models. Increasing Italian Mediterranean Index score (indicating better adherence) was associated with lower 5-year weight change in volunteers of normal weight at baseline (β -0.12, 95% CI -0.16 to -0.08 for 1 tertile increase in score), but not in those overweight/obese at baseline (P interaction between Index score and BMI 0.0001). High adherence was also associated with reduced risk of becoming overweight/obese (OR 0.91, 95% CI 0.84-0.99 third vs. first tertile); smaller 5-year change in waist circumference (β -0.09, 95% CI -0.14 to -0.03 for 1 tertile increase in score); and lower risk of abdominal obesity (OR 0.91, 95% CI 0.84-0.99 third vs. first tertile). Adherence to a traditional Italian Mediterranean diet may help prevent weight gain and abdominal obesity.

BACKGROUND: Adherence to a Mediterranean diet may improve longevity, but relevant data are limited.

METHODS: We conducted a population-based, prospective investigation involving 22,043 adults in Greece who completed an extensive, validated, food-frequency questionnaire at base line. Adherence to the traditional Mediterranean diet was assessed by a 10-point Mediterranean-diet scale that incorporated the salient characteristics of this diet (range of scores, 0 to 9, with higher scores indicating greater adherence). We used proportional-hazards regression to assess the relation between adherence to the Mediterranean diet and total mortality, as well as mortality due to coronary heart disease and mortality due to cancer, with adjustment for age, sex, body-mass index, physical-activity level, and other potential confounders.

RESULTS: During a median of 44 months of follow-up, there were 275 deaths. A higher degree of adherence to the Mediterranean diet was associated with a reduction in total mortality (adjusted hazard ratio for death associated with a two-point increment in the Mediterranean-diet score, 0.75 [95 percent confidence interval, 0.64 to 0.87]). An inverse association with greater adherence to this diet was evident for both death due to coronary heart disease (adjusted hazard ratio, 0.67 [95 percent confidence interval, 0.47 to 0.94]) and death due to cancer (adjusted hazard ratio, 0.76 [95 percent confidence interval, 0.59 to 0.98]). Associations between individual food groups contributing to the Mediterranean-diet score and total mortality were generally not significant.

CONCLUSIONS: Greater adherence to the traditional Mediterranean diet is associated with a significant reduction in total mortality.

PURPOSE:To characterize the lifestyle and nutritional risk profile associated with the Mediterranean diet in a Portuguese population with and without age-related macular degeneration (AMD).

METHODS:Nested case-control study (n = 883) within the Coimbra Eye Study, including 434 subjects with AMD and 449 age- and sex-matched subjects without AMD. All enrolled subjects underwent a full risk assessment, including lifestyle-related risk factors and a thorough food frequency questionnaire. This allowed us to build an adherence score to the Mediterranean diet (mediSCORE, range 0-9) constructed from individual food intakes. Food intake was also further analysed by conversion to micronutrient consumption.

RESULTS:Our results suggest that physical activity has a protective role in AMD [p = 0.018 after multivariate adjustment, OR: 0.69 (0.51-0.93)]. High (mediSCORE ≥6) was also found to be protective [p = 0.041, OR: 0.62 (95% CI: 0.38-0.97)]. Food group analysis unveiled a specific protective role for increased fruits consumption (p = 0.029). Finally, micronutrient analysisrevealed a protective role associated with increased consumption of caffeine, fibres, beta-carotene, vitamin C and vitamin E (p < 0.05).

CONCLUSION:High mediSCORE appears to confer protection against the development of AMD in a Mediterranean population. This effect is driven by increased consumption of fruits and some antioxidant micronutrients, which emerged as statistically significant protective factors. Further studies are required to establish dietary recommendations with clinical application.

BACKGROUND:A Mediterranean-style diet (MedSD) is associated with positive health outcomes, particularly reduced risk of cardiovascular disease. It is of interest to assess the feasibility of adherence to a MedSD in a subset of older adults in the United States.

OBJECTIVE:To assess the efficacy of implementing a MedSD intervention in a subset of postmenopausal women living in the United States, and to detect the influence of this dietary pattern on blood lipid levels.

DESIGN:A partial feeding, nutrition counseling, pilot study with a one-group longitudinal design.

PARTICIPANTS:Sixteen healthy, postmenopausal, American women living in suburban communities in Farmington, CT, with a mean±standard deviation age of 77±6.8 years and a body mass index of 26.1±3.1.

INTERVENTION:Participants were counseled by a registered dietitian nutritionist on how to follow a MedSD, which included increased sources of n-3 polyunsaturated fatty acids, fruits, and vegetables, and decreased saturated fat, n-6 polyunsaturated fatty acids, and simple sugars for 12 weeks. To maintain isocaloric conditions, participants were asked to substitute sources of saturated fat and refined carbohydrates for extra virgin olive oil (3 T/day), walnuts (1.5 oz/day), and fatty fish (3 to 5 servings/wk), which were provided at 3-week intervals.

MAIN OUTCOME MEASURES:Dietary adherence measures included the Mediterranean Diet Score, 3-day diet records, and serum fatty acid and lipid profiles.

STATISTICAL ANALYSES:Mixed model longitudinal analyses were conducted to assess changes over time (Weeks 0, 12, and 24) in the outcome variables.

RESULTS:Mediterranean Diet Score increased by 8.9 points (P<0.001) after the MedSD phase. Dietary sugar decreased by 10.8 g (P<0.05), total dietary n-3 increased by 1.6 g (P<0.01), total dietary n-6 increased by 5.5 g (P<0.01), and dietary n-6:n3 ratio decreased by 3.6 units (P<0.01). In serum, 22:6 (n-3), 20:5 (n-3), and 18:3 (n-3) increased (P<0.001, P<0.01, and P<0.001, respectively), and 14:0, 16:0, 17:0, 20:4 (n-6), 22:4 (n-6) declined after the intervention (P<0.01, P<0.001, P<0.01, P<0.01, and P<0.001, respectively), which support a change in dietary intake toward a MedSD. Serum high-density lipoprotein cholesterol levels increased by 3.8 mg/dL (0.098 mmol/L) (P<0.05) and serum triglyceride levels decreased by 11.6 mg/dL (0.131 mmol/L) (P<0.10).

CONCLUSIONS:A pilot study of a 12-week MedSD intervention with counseling from a registered dietitian nutritionist can favorably influence the dietary pattern and lipid profile of postmenopausal women living in the United States.

BACKGROUND:Insulin resistance is associated with higher breast cancer (BC) penetrance in BRCA mutation carriers. Metabolic syndrome (MetS), an insulin resistance syndrome, can be reversed by adhering to the Mediterranean diet (MedDiet). In a dietary intervention trial on BRCA mutation carriers, we evaluated adherence to the MedDiet, and the association with the MetS, by analyzing data from the Mediterranean Diet Adherence Screener (MEDAS).

METHODS:BRCA mutation carriers, with or without BC, aged 18 to 70 years, were eligible for the trial. After the baseline examinations, women were randomized to a dietary intervention or to a control group. Both groups completed the MEDAS at baseline and at the end of the dietary intervention.

RESULTS:A total of 163 women completed the 6 months of dietary intervention. Compared with controls, the women in the intervention group significantly reduced their consumption of red meat ( P<.01) and commercial sweets ( P<.01) and their MEDAS score rose significantly (+1.3 vs +0.55, P = .02). The number of MetS parameters decreased with increasing points of adherence to the MEDAS score ( P = .01). In the intervention group, there was a significant association with the greater reduction of MetS.

CONCLUSION:BRCA mutation carriers in the intervention group experienced greater improvement in their MedDiet and MetS parameters.

Prostate cancer (PCa) is the second most frequently diagnosed cancer and the sixth leading cause of death from cancer worldwide. Countries following a Mediterranean-type dietary pattern, has been reported to have lower PCa incidence and mortality compared with other European regions. A population-based case-control study has been conducted from January 2015 to December 2016 in a single institution of the municipality of Catania, southern Italy. A total of 118 PCa and 238 population-based controls were collected. Controls had significantly higher adherence to the Mediterranean diet, which was evident for several subgroups (including age groups, overweight and obese men, current smokers, alcohol intake, low and medium physical activity levels). PCa cases were found to consume lower amount of vegetables (223 g/d vs. 261 g/d; p = 0.001), legumes (34.26 g/d vs. 53.55 g/d; p = 0.003), and fish (47.75 g/d vs. 58.3 g/d) than controls; other differences emerged were related to alcohol intake (12.37 g/d vs 5.07 g/d; p < 0.01), cereals (254.06 g/d vs.235.94 g/d; p < 0.001), dairy (196 g/d vs. 166 g/d; p < 0.001), and meat consumption (98.09 g/d vs. 70.15 g/d; p < 0.001). However, no statistically significant differences between cases and controls were found regarding fruit, legumes, and olive oil consumption. The Mediterranean diet score was inversely associated with lower likelihood of having PCa in a linear manner (odds ratio [OR]: 0.86 [95% CI 0.77-0.96]). Specifically, individuals in the highest group of adherence had 78% less likelihood of have PCa and 14% less likelihood for each point increase of the score. The model adjusted for total polyphenol intake showed still a significant inverse association between adherence to the Mediterranean dietand PCa, but the relation was no more linear and not significant for one-point increase of the score (OR: 0.88 [95% CI 0.77-1.01]). In our cohorts of Italian men, we observed that high adherence to the Mediterranean diet was inversely associated with likelihood of having PCa cancer.

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.

The aim of this study is to evaluate the association between adherence to Mediterranean diet (MD) and gastric cancer (GC). A case-control study was carried out at the Fondazione Policlinico 'A. Gemelli' (Rome, Italy) from 2003 to 2015. A total of 223 incident cases and 223 controls were interviewed. Dietary intake was assessed through a validated food frequency questionnaire that collected information on more than 25 food items. The association between adherence to MD and risk of GC was quantified by calculating Odds Ratios (OR) and 95% confidence intervals (CI). The analysis reports that a higher adherence to MD is associated with a reduced risk of GC (OR: 0.70; 95% CI: 0.61-0.81). A high consumption of vegetables (OR: 0.34; 95% CI: 0.14-0.85), legumes (OR: 0.13; 95% CI: 0.06-0.29), and fish (OR: 0.33; 95% CI: 0.15-0.68), as well as low consumption of meat (OR: 0.29; 95% CI: 0.10-0.85) and alcohol (OR: 0.46; 95% CI: 0.24-0.90) are consistently related to a lower risk of GC. Our study indicates a protective role of the MD eating pattern and MD individual components against GC. Our results showed a beneficial role of high vegetable, legume, and fish consumption, along with low intake of alcohol and meat in the development of GC.

Evidence from recent years highlighted the importance of the Mediterranean diet for brain health. We investigated the association between adherence to Mediterranean diet and change in cognitive functions two decades later in patients with cardiovascular disease (CVD).Participants were men with a history of CVD, who previously participated in the Bezafibrate Infarction Prevention (BIP) trial between 1990 and 1997, had a food diary record, and underwent cognitive evaluations 14.6 ± 1.9 years (T1) and 19.9 ± 1.0 years after baseline (T2) as part of the BIP Neurocognitive study (= 200, mean age at 57.3 ± 6.3 years). Adherence to the Mediterranean diet was determined from the self-administered 4-day food diary record, with patients categorized into high, middle and poor levels of adherence if they received>5, 4-5 and<4 points, respectively. Cognitive function was assessed using the NeuroTrax computerized battery. Linear mixed models were applied.Among the 200 patients, 52 (26%) had poor adherence, 98 (49%) had middle adherence and 50 (25%) had high levels of adherence to the Mediterranean diet. Those categorized to the poor adherence level had poorer cognitive function at T1 compared to the other groups. Additionally, poor vs. high level of adherence was associated with a greater decline in overall cognitive performance [-score = -0.23 and 95% confidence interval (CI), -0.43;-0.04; = 0.021] and in visual spatial functions (-0.46 95% CI, -0.86;-0.06; = 0.023).This study stresses the possible role of the Mediterranean diet in men with a high vascular burden and may set the ground for future intervention to reduce their risk for cognitive decline.

The aims of this study were to assess the association of adherence to the Mediterranean diet (MD) with physical fitness and body composition in Spanish university students and to determine the ability to predict the MD adherence of each Mediterranean Diet Adherence Screener (MEDAS) item. A cross-sectional study was performed involving 310 first-year university students. Adherence to the MD was evaluated with MEDAS-14 items. Anthropometric variables, body composition, and physical fitness were assessed. Muscle strength was determined based on handgrip strength and the standing long jump test. Cardiorespiratory fitness (CRF) was measured using the Course-Navette test. Only 24% of the university students had good adherence to the MD. The ANCOVA models showed a significant difference between participants with high adherence to the MD and those with medium and low adherence in CRF (= 0.017) and dynamometry (= 0.005). Logistic binary regression showed that consuming>2 vegetables/day (OR = 20.1; CI: 10.1-30.1;<0.001), using olive oil (OR = 10.6; CI: 1.4-19.8;= 0.021), consuming<3 commercial sweets/week (OR = 10.1; IC: 5.1-19.7;<0.001), and consuming≥3 fruits/day (OR = 8.8; CI: 4.9-15.7;<0.001) were the items most associated with high adherence to the MD. In conclusion, a high level of adherence to the MD is associated with high-level muscular fitness and CRF in Spanish university students.

No known cohort study has investigated whether the Mediterranean diet can reduce incident coronary heart disease (CHD) events in a Mediterranean population. This study examined the relation between Mediterranean diet adherence and risk of incident CHD events in the 5 Spanish centers of the European Prospective Investigation into Cancer and Nutrition. Analysis included 41,078 participants aged 29-69 years, recruited in 1992-1996 and followed up until December 2004 (mean follow-up:10.4 years). Confirmed incident fatal and nonfatal CHD events were analyzed according to Mediterranean diet adherence, measured by using an 18-unit relative Mediterranean diet score. A total of 609 participants (79% male) had a fatal or nonfatal confirmed acute myocardial infarction (n = 468) or unstable angina requiring revascularization (n = 141). After stratification by center and age and adjustment for recognized CHD risk factors, high compared with low relative Mediterranean diet score was associated with a significant reduction in CHD risk (hazard ratio = 0.60, 95% confidence interval: 0.47, 0.77). A 1-unit increase in relative Mediterranean diet score was associated with a 6% reduced risk of CHD (95% confidence interval: 0.91, 0.97), with similar risk reductions by sex. Mediterranean diet adherence was associated with a significantly reduced CHD risk in this Mediterranean country, supporting its role in primary prevention of CHD in healthy populations.
