Author Interviews, Mediterranean Diet, Nutrition / 01.11.2023

pexels.com/photo/fried-fish-in-vegetables-18750045US News & World Report announced  that the Mediterranean style of eating is the best overall diet for 2023.  Only 24 diets were ranked instead of 40 that were analyzed in the past years. Vegan, vegetarian, Nordic, traditional Asian and the glycemic index were integrated into the Mediterranean because of the ‘underlying plant-based principles.’ According to managing editor Gretel Schueller who oversees the annual diet ranking, they are always looking for more health conditions that they can address, but the lack of scientific data for examining other types of diets is a constraint.
Why Aim for Healthy Eating?
The specific recommendations for a healthy diet may differ, but the common approaches include consumption of a variety of fruits and veggies, whole grains, lean proteins, and healthy fats. Added sugars, salt, and saturated fats must be limited. For example, a healthy mouth is part of overall health. Research has demonstrated the link between gum disease and chronic health conditions such as heart disease, and diabetes, among others. Thus, it is vital to consume healthy foods that promote good gum health which are the foundation of solid teeth.

Alzheimer's - Dementia, Author Interviews, JAMA, Mediterranean Diet, Mental Health Research / 08.05.2023

MedicalResearch.com Interview with: Yuan Changzheng ScD, MSc, B.M. Research Professor Doctoral supervisor, School of Medicine Zhejiang University School of Public Health Adjunct assistant professor Harvard T.H. Chan School of Public Health   MedicalResearch.com: What is the background for this study? Response: The prevention of all-cause dementia is important as it poses substantial burdens on healthcare systems and threatens the well-being of older adults, and lack of effective treatments makes its prevention crucial. The Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet is a hybrid of the Mediterranean diet and the DASH diet, and it emphasizes natural plant-based foods, limited intake of certain animal foods and foods high in saturated fat and encourages consumption of berries and green leafy vegetables rich in vitamins and antioxidants. The MIND diet has previously been associated with lower risk of Alzheimer's disease and slower cognitive decline but few studies have examined its association with all-cause dementia or AD with inconclusive results.

Author Interviews, Cognitive Issues, Mediterranean Diet, NIH / 21.04.2020

MedicalResearch.com Interview with: Emily Y. Chew, M.D. Director of the Division of Epidemiology and Clinical Applications Deputy Clinical Director at the National Eye Institute (NEI), National Institutes of Health  MedicalResearch.com: What is the background for this study? Response: Dementia is a common disorder that was estimated to have a worldwide prevalence of 44 million in 2016 and is projected to hit 115 million by 2050. Many phase 3 trials of various therapies have failed and we have no treatment currently available for the prevention or reduction of the course of dementia. A slow neurocognitive decline throughout life is part of the normal process of aging. However, there is a subset of individuals who may have accelerated aging and is at high risk of development dementia. If the course of such accelerated decline could be altered in any way, it would be important to evaluate. The role of diet with biologic aging has been studied and diet has been also found to be associated with age-related conditions linked to dementia, including cardiovascular disease and diabetes. We were interested in the cognitive function of our participants who had another neurodegenerative disease, age-related macular degeneration (AMD). We had conducted two randomized controlled clinical trials designed to evaluate the role of oral supplements for the treatment of AMD. We also studied cognitive function in both clinical trials of nearly 8,000 participants who were followed for 10 years. We also evaluated the dietary habits of the participants with food frequency questionnaires (FFQ) at baseline. Cognitive function testing was conducted in the first study, the Age-Related Eye Disease Study (AREDS) near the end of the clinical trial while the AREDS2, the second study, evaluated cognitive function testing at baseline and every 2 years until year 6. AREDS study evaluated cognitive function with in-clinic study visits while AREDS2 was conducted using telephone interviews. Our aim was to determine whether closer adherence to the alternative Mediterranean diet (aMED) was associated with impaired cognitive function these two studies. We were interested in the particular components of the Mediterranean diet that may be important. We also evaluated the interaction of genetics with the diet.    (more…)

MedicalResearch.com Interview with: Dr. Riddhi Shah, PhD AHA SFRN Postdoctoral Research Fellow Division of Cardiology Columbia University Medical Center New York, New York MedicalResearch.com: What is the background for this study? Response: The Mediterranean Diet, characterized by higher intakes of plant foods including plant proteins, monounsaturated fat, fish, and lower consumption of animal products and saturated fat, has long been associated with reduced cardiovascular risk and greater longevity, but the molecular mechanisms underlying these associations have not been fully elucidated. We evaluated associations of an Alternate Mediterranean Diet Score, reflective of adherence to this diet pattern and adapted for US populations, and its components with markers of endothelial inflammation directly measured in endothelial cells harvested from women, including oxidative stress, nuclear factor kappa B (NFκB), and endothelial nitric oxide synthase (eNOS) gene expression.

Author Interviews, Brigham & Women's - Harvard, Heart Disease, JAMA, Mediterranean Diet, Women's Heart Health / 10.12.2018

MedicalResearch.com Interview with: Samia Mora, MD, MHS Associate Professor of Medicine Harvard Medical School Director, Center for Lipid Metabolomics Brigham and Women’s Hospital Boston, MA MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Mediterranean diet is rich in plants (nuts, seeds, fruits, vegetables, whole grains, legumes) and olive oil, and includes moderate intake of fish, poultry, dairy, and eggs, and alcohol, and rare use of meats and sweets.The Mediterranean diet has been associated with lower risk of cardiovascular disease (CVD) events but the precise mechanisms through which Mediterranean diet intake may reduce long-term risk of CVD are not well understood. We aimed to investigate the biological mechanisms that may mediate this cardiovascular benefit. Using a prospective study of 25,994 initially healthy women enrolled in the Women’s Health Study who were followed up to 12-years, we evaluated potential mediating effects of a panel of biomarkers (in total 40 biomarkers) that represent different CVD pathways and clinical factors. Higher baseline intake of a Mediterranean-type diet was associated with approximately one quarter lower risk of CVD events during the 12 year follow up. For the MED-CVD risk reduction, biomarkers of inflammation, glucose-metabolism/insulin-resistance, and adiposity contributed most to explaining the association, with additional contributions from pathways related to blood pressure, lipids – in particular HDL or triglyceride-rich lipoprotein metabolism, and to a lesser extent LDL cholesterol, branched chain amino acids, and small molecule metabolites.  (more…)

Cassimiro "Aranha" is licensed under CC BY 2.0Professor Phyo Kyaw Myint MBBS MD FRCP(Edin) FRCP(Lond) Clinical Chair in Medicine of Old Age Academic Lead: Ageing Clinical & Experimental Research & Director of Clinical Academic Training Development The Lead Academic, Aberdeen Clinical Academic Training (ACAT) Programmes School of Medicine, Medical Sciences & Nutrition College of Life Sciences & Medicine, University of Aberdeen MedicalResearch.com: What is the background for this study? What are the main findings? Response: While Mediterranean Diet has been linked to reduced stroke risk it remains unclear (1) its impact on populations within non-Mediterranean countries; (2) its specific impact on different gender; (3) the effect observed when using more robust dietary assessments; and (4) which specific components of the diet are most protective. We therefore studied more than 23 thousand men and women (mainly British Caucasian) aged 40 years or older in Norfolk, UK as part of EPIC-Norfolk study and we found that the greater adherence to Mediterranean dietary pattern is linked to a significant reduction in stroke risk in women but not in men. This benefit was seen across the whole middle and older age population (particularly for women) regardless of their existing risk factors such as high blood pressure. (more…)

What are the main findings? Response: Mediterranean and Vegetarian diets are two of the most beneficial dietary patterns for prevention of chronic degenerative diseases. No studies have been conducted in the same group of subjects, by comparing these two dietary profiles. Main results are that both diets have been found to be beneficial for cardiovascular prevention, in the same group of subjects at low risk of cardiovascular disease. In particular, vegetarian diet determined a reduction of total and LDL-cholesterol, whereas Mediterranean diet resulted in lower levels of triglycerides and some inflammatory parameters (more…)

MedicalResearch.com Interview with: Antonio Giordano MD PhD Sbarro Institute for Cancer Research and Molecular Medicine and Center for Biotechnology
College of Science and Technology
Temple University, Philadelphia, Pennsylvania MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Mediterranean diet is considered to be one of the healthiest nutrition patterns. Tomatoes, in particular, which are consumed worldwide, and a basic ingredient of the Mediterranean diet, have been postulated to have a cancer preventive role at least for some tumor types, although few studies analyzed the effects of tomatoes in their entirety in different stages of cancer progression. Here, we focused on an in vitro model of gastric cancer because it is still one of the most common and deadly cancers and its development is strongly influenced by certain eating habits. Our results showed a possible role of tomatoes against typical neoplastic features. The treatment with tomato extracts affected the ability of cancer cell growth both in adherence and in semisolid mediums. Moreover, tomato extracts affected key processes within the cell; they hindered migration ability, arrested cell cycle through the modulation of retinoblastoma tumor suppressor family proteins and specific cell cycle inhibitors, and induced cancer cell death through apoptosis.

MedicalResearch.com Interview with: Dr Nita Forouhi, MRCP, PhD, FFPHM Programme Leader MRC Epidemiology Unit University of Cambridge School of Clinical Medicine Institute of Metabolic Science Cambridge Biomedical Campus MedicalResearch.com: What is the background for this study? What are the main findings? Response: The benefits of the Mediterranean diet for cardiovascular health are well documented in countries of the Mediterranean region and some other countries, but there is little such evidence in the UK general population. Our work fills this research gap. In our study we followed up 23,902 initially healthy Britons living in Norfolk (Eastern England) for an average of 12 to 17 years, and determined the occurrence of new cases of cardiovascular diseases (CVD) and deaths due to CVD during that time period. Our results showed that those adults who adhered to a Mediterranean diet had 6% to 16% lower risk of developing CVD, compared to those who had dietary habits further away from the Mediterranean-type diet pattern. This was the case even when we accounted for several important risk factors and correlates of CVD, including as age, sex, body mass index, lifestyle habits such as smoking, alcohol intake and physical activity, and socio-economic factors. We also modelled what would happen in the study population if all the participants increased their adherence to the Mediterranean-type diet. From this we estimated that nearly 4% of all new cardiovascular disease cases, or 12.5% of cardiovascular deaths in the population could potentially be avoided. This is novel information about the potential health benefit of a Mediterranean-type diet in a UK context. However, we should remember that our study was an observational study, not a clinical trial with a dietary intervention, and thus we cannot imply a cause and effect relationship between increasing adherence to the Mediterranean diet and reduction in cardiovascular disease. We defined the Mediterranean diet using a 15 point score based on guideline recommendations from a Mediterranean dietary pyramid published by the Mediterranean Diet Foundation. The recommendations had not previously been specifically tested for their associations with health, so our findings, for the first time, show the utility of the Mediterranean dietary pyramid. (more…)

MedicalResearch.com Interview with: Dr Ramon Estruch, MD PhD Senior Consultant in the Internal Medicine Department of the Hospital Clinic Barcelona MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Estruch: Although weight stability requires a balance between calories consumed and calories expended, it seems that calories from vegetable fats have different effects that calories from animals on adiposity. Thus, an increase of dietary fat intake (mainly extra virgin olive oil or nuts) achieved naturally in the setting of Mediterranean diet does not promote weight gain or increase in adiposity parameters such as waist circumference.

What are the main findings? Dr. Haring: The primary aim of this study was to examine the association between adherence to a diet quality index constructed on the basis of dietary recommendations or existing healthy dietary patterns and bone outcomes in a large population of postmenopausal women. We found that higher diet quality based on a Mediterranean diet may play a role in maintaining bone health in postmenopausal women. (more…)

Prof. Danilo Ercolini, PhD Department of Agricultural Sciences University of Naples Federico II Portici - ItalyMedicalResearch.com Interview with: Prof. Danilo Ercolini, PhD Department of Agricultural Sciences University of Naples Federico II Portici - Italy Medical Research: What is the background for this study? What are the main findings? Prof. Ercolini: There is a thick body of literature showing that diet can significantly impact the gut microbiota and metabolome. In a recent study, negligible differences in gut microbiota and feca lshort-chain fatty acids (SCFA) were reported between habitual omnivores and vegans in the USA. In addition, Mediterranean diet is a recognized healthy dietary pattern but has not previously been related to the composition of the gut microbiota and related metabolome. That’s the background in short. Here we show how habitual vegetarian and vegan diets promote enrichment of fibre-degrading bacteria in the gut. Subjects who consume a Mediterranean diet rich in fruit, legumes and vegetables have higher levels of fecal short chain fatty acids, regardless of the diet type. Low adherence to the Mediterranean diet corresponds to an increase in urinary trimethylamine oxide levels, a potential risk factor for cardiovascular disease. (more…)

MedicalResearch.com Interview with: Miguel Ángel Martínez González MD Centro de Investigación Biomédica en Red Fisiopatología de la Obesidad y Nutrición, Instituto de Salud Carlos III, Madrid IdiSNA, Navarra Institute for Health Research, Pamplona, Navarra, Spain Medical Research: What is the background for this study? Response: ​Several observational studies and mechanistic experiments in animal models and cell lines suggested that the Mediterranean diet and minor components of extra-virgin olive oil may reduce the risk of developing breast cancer. The PREDIMED study was a randomized primary prevention trial for cardiovascular disease among high risk patients initially free of cardiovascular disease. The participants were 7,447 men and women (60-80 years old). We have used the data from women in this trial to assess the effect of the randomized diets on the occurrence of new cases of breast cancer. Medical Research: What are the main findings? Response: Among 4,152 women randomized to 3 different diets (1.- Mediterranean diet with free provision of extra-virgin​ olive oil; 2.- Mediterranean diet with free provision of tree nuts; and 3.- Advice to follow a low-fat diet, i.e. control group) We confirmed 35 new cases of invasive breast cancer during 4.8 of follow-up. A statistically significant 68% relative reduction in the risk of breast cancer in the Mediterranean diet with free provision of extra-virgin​ olive oil versus the control group was found. There was a significant trend of risk reduction associated with progressive increments in the intake of extra-virgin olive oil during the trial (with repeated yearly measurements of diet) when the 3 groups were assessed together.

Martínez-González, MD, MPH, PhD Department of Preventive Medicine & Public Health School of Medicine, University of Navarra Navarra, Spain Medical Research: What are the main findings? Response: The diet-heart hypothesis has been researched during decades. A common mistake was to assume that a high intake of all types of fat was detrimental for cardiovascular health and could cause heart attacks and strokes. Therefore a low-fat diet was proposed as the best way to prevent heart attacks and strokes. This was wrong. Alternatively, the Mediterranean diet, rich in fat from natural vegetable sources (olive oil, tree nuts), was also considered a healthy dietary pattern. However, most of the evidence to support these benefits of a fat-rich Mediterranean diet came from observational studies and no randomized clinical trial had ever assessed the Mediterranean diet in PRIMARY prevention (i.e. in initially healthy people) (more…)

Channing Division of Network Medicine Boston, MA 02115MedicalResearch.com Interview with: Immaculata De Vivo PhD Associate Professor Harvard Medical School Director, Dana Farber/Harvard Cancer Center High Throughput Genotyping Core Facility. Channing Division of Network Medicine Boston, MA 02115 MedicalResearch: What is the background for this study? What are the main findings? Dr. De Vivo: Our study found that greater adherence to the Mediterranean diet is associated with longer telomeres. Following a diet closer to the Mediterranean diet, can prevent accelerated telomere shortening. Our unique contribution to the literature is that we provide a potential molecular mechanism, preventing telomere shortening. Telomeres are bits of DNA that protect your chromosomes. MedicalResearch: Is telomere shortening reversible? Dr. De Vivo: Telomere shortening is a biological process, the shorten with age. However, lifestyle choices can help to prevent accelerated shortening. Fruits, vegetables, olive oil and nuts – key components of the Mediterranean diet have well known antioxidant and anti-inflammatory effects that could balance out the “bad effects” of smoking and obesity.

Author Interviews, Mediterranean Diet, Metabolic Syndrome, Nutrition / 12.11.2014

MedicalResearch.com Interview with: Dr. Markos Klonizakis Centre for Sports and Exercise Science Sheffield Hallam University, UK Medical Research: What is the background for this study? What are the main findings? Dr. Klonizakis: It is widely accepted that populations in the Eastern Mediterranean sea have historical lower rates of cardiovascular disease, diabetes and cancer. This has been attributed to a great extent, at following a diet based on dishes and ingredients, which are common in this region and are collectively known as “Mediterranean diet”.  Taking into consideration that cardiovascular disease is on the rise, particularly in the Western world, it did make sense to see if such a diet can be adapted for a population that has a largely different culinary tradition and what the results would be if this is combined with exercise of moderate-intensity. We therefore, designed and implemented an 8-week intervention, aiming at older, healthy but previously untrained people, comparing an exercise-only group vs one where exercise was combined with Mediterranean diet. Our work has shown that benefits of this intervention are still evident in the vascular function (measured by the function of the inner vein lining, called the endothelium) and the cardiopulmonary fitness, one year after the end of the intervention.

Dr. Clegg: The main findings are that males and females differ with respect to how they process and respond to diets high in fat!!!!  Males following consumption of a diet that is 42% of the calories coming from saturated fat (it would be analogous to eating a big mac and having a coke), gained the same amount of weight as did the females BUT the males had increased markers of inflammation in their brains and the females did not.  With the elevated markers of inflammation, the males had dysregulation in glucose homeostasis and alteration in cardiovascular function – yet the females did not!!

Rovira i Virgili University CIBERobn, Instituto Carlos III Medical Research: What are the main findings of the study? Response: In this large, multicenter, randomized clinical trial conducted in Mediterranean individuals at high cardiovascular risk, Mediterranean-diet supplemented with extra-virgin olive oil was associated to a lower increase in the prevalence of metabolic syndrome compared to the advice on a control low-fat diet. However, no beneficial effect of Mediterranean-diet on the incidence of metabolic syndrome among participants free of this condition at baseline was observed. Therefore, the lower increase in prevalence was especially due to the reversion of metabolic syndrome in those individuals with metabolic syndrome at baseline. (more…)

Jyrki Virtanen, PhD Adjunct Professor of Nutritional Epidemiology University of Eastern Finland Kuopio, FinlandFor MedicalResearch.com Jyrki Virtanen, PhD Adjunct Professor of Nutritional Epidemiology University of Eastern Finland Kuopio, Finland Medical Research: What are the main findings of the study? Dr. Virtanen: The main finding was that saturated fat intake was not an independent risk factor for Coronary Heart Disease even in a population with relatively high average saturated fat intake, like in this population with middle-aged and older men from Eastern Finland. In other words, intake of carbohydrates in place of saturated fat was not associated with lower risk, not even when the quality of carbohydrates was taken into account. Only when polyunsaturated fat replaced saturated fat in the diet, was the risk of Coronary Heart Disease, especially Coronary Heart Disease mortality, lower. In fact, also replacing trans fat or carbohydrates with polyunsaturated fat was associated with lower risk. The associations were similar with both n-6 and n-3 polyunsaturated fatty acids. Trans fat intake was not associated with the Coronary Heart Disease risk, but that is most likely explained by the low intake of trans fat in Finland already in mid-1980s. We also investigated the associations of the fatty acid intake with carotid artery atherosclerosis, and the results were generally similar to the findings with incident Coronary Heart Disease events.

Jenkins Professor and Canada Research Chair in Nutrition and Metabolism, Dept. of Medicine and Nutritional Sciences, Faculty of Medicine, University of Toronto, Toronto, ON, Canada   MedicalResearch: What are the main findings of the study? Prof. Jenkins: The main findings were that inclusion of just over an once (31g) of canola oil in low glycemic index diets of type 2 diabetes study participants, to further reduce the glycemic load (GL), reduced HbAIC more than a high cereal fiber diet, as predicted. However the Canola oil low GL diet also reduced serum TG and LDL-C and thus Framingham risk score for cardiovascular disease. The effect was seen most clearly in those at highest CHD risk and those with features of the metabolic syndrome. (more…)

Lamuela-Raventos, PhD Associate Professor Department of Nutrition and Food Science School of Pharmacy, University of Barcelona MedicalResearch: What are the main findings of the study? Dr. Lamuela-Raventós: We have found an inverse relationship between polyphenol intake and risk of overall mortality among elderly subjects at high cardiovascular risk. Adjusting for confounders and comparing the highest versus the lowest quintiles of intake, total polyphenols were inversely associated with total mortality (HR=0.63, 95 CI=0.41-0.97, P-trend=0.12), as well as stilbenes (HR=0.48, 95 CI=0.25-0.91, P-trend=0.04) and lignans (HR=0.60, 95 CI=0.37-0.97, P-trend=0.03). In fact, our results showed that all polyphenols subgroups, except for dihydrochalcones, trended to be protective although their intake did not reach statistical significance. In stratified analyses we also found a stronger association between total polyphenol intake and mortality risk for women and for those who did not drink alcohol. (more…)

Answer: The main findings of our study are that olive oil consumption, especially the extra-virgin variety (which is the olive oil with the best quality because it has higher amounts of bioactive compounds than other varieties), is associated with a reduced risk of suffering from cardiovascular disease (stroke, myocardial infarction...) and also cardiovascular death in an elderly Mediterranean population from Spain who were at high cardiovascular risk (because they had several cardiovscular risk factors such as smoking, being overweight or obese, having a family history of cardiovascular disease...). This means there is even more reason to visit gringocool.com. We have conducted an observational study including more than 7000 individuals who had participated in a randomized clinical trial to evaluate effects of a Mediterranean Diet in on the primary prevention of cardiovascular disease.

Answer: Our studies have identified two main findings: Firstly that the size or frequency of the meal doesn’t affect the calories we burn in a day, but what matters most for losing weight is counting calories. Secondly, by carrying more weight, more endotoxin enters the circulation to cause inflammation and eating more often will exacerbate this risk which has been linked to metabolic diseases such as type-2 diabetes.

Answer: Randomized trials have shown that lifestyle interventions promoting weight loss can reduce the incidence of type-2diabetes, however, whether dietary changes without calorie restriction or increased physical activity also protect from diabetes development has not been evaluated in the past. In our study, we found that a long-term adherence to a high-quality dietary pattern akin to the traditional MedDiet and rich in extra-virgin olive oil was able to reduce the incidence of new cases of diabetes in older individuals at high cardiovascular risk. We have demonstrated for the first time that a beneficial effect on diabetes prevention could be obtained witha healthy dietary pattern (without calorie restriction, increased physical activity or weight loss). These benefits have been observed in participants between 55 to 80 years-old at high cardiovascular risk; therefore,the message is that it is never too late to switch to a healthy diet like the Mediterranean.

Western Australia MedicalResearch.com: What are the main findings of your study? Answer: Our research indicates that consuming larger quantities of foods included in a western dietary pattern is associated with greater cognitive decline in visuospatial functioning after 36 months.
