Alzheimer's - Dementia, Author Interviews, Nutrition / 26.11.2022

MedicalResearch.com Interview with: Thomas M Holland, MD, MS Assistant Professor Rush Institute for Health Aging Rush College of Medicine & Rush College of Health Sciences https://www.rushu.rush.edu/faculty/thomas-m-holland-md-ms MedicalResearch.com: What is the background for this study? Response: My late mentor Martha Clare Morris, ScD had published a manuscript investigating leafy green intake, and the nutrients found therein, and cognition. I wanted to take this thought a step further and investigate the potential association bioactives, found in vegetables, like leafy greens, has to cognition. Further, this is a continuation of the research I published in the green journal in 2020 associating flavonols to incident Alzheimer’s dementia. This study extends the understanding that flavonols are not only beneficial for the most detrimental outcome of Alzheimer’s dementia (in decreasing the risk), but also advantageous in mitigating components of the, clinical syndrome i.e. decreasing the rate of cognitive decline.

Alzheimer's - Dementia, Author Interviews, Nutrition / 14.11.2022

MedicalResearch.com Interview with: Alessandro Palmioli PhD Cristina Airoldi PhD Department of Biotechnology and Biosciences, University of Milano-Bicocca, NeuroMI, Center for Neuroscience, University of Milano-Bicocca MedicalResearch.com: What is the background for this study? beer-hopsResponse: We started many years ago by studying some natural and synthetic molecules that were able to counteract the early stages of this disease. With a view to early prevention, we wondered if these molecules could be routinely taken with the diet or dietary supplements. So our studies focused on the search for bioactive molecules present in food and edible plants. Hops are very rich in polyphenolic compounds, and for this reason it is historically used for the production of beer, but also for the preparation of herbal teas and infusions, and its uses in traditional medicine are known. In recent years we have also collected interesting results on Coffee, Sage, Radix Imperatoriae, Cocoa and Cinnamon extracts. (more…)
Author Interviews, Brigham & Women's - Harvard, JAMA, Nutrition, Occupational Health, Sleep Disorders / 09.11.2022

MedicalResearch.com Interview with: Zhilei Shan, MD, PhD Postdoctoral fellow on Nutritional Epidemiology Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: Unhealthy sleep behaviors and sleep disturbances are associated with higher risk of multiple diseases and mortality. The current profiles of sleep habits and disturbances, particularly the differences between workdays and free days, are unknown in the contemporary US. MedicalResearch.com: What are the main findings? Response: In this nationally representative cross-sectional analysis with 9004 adults aged 20 years or older, differences in sleep patterns between workdays and free days were observed. The mean sleep duration was 7.59 hours on workdays and 8.24 hours on free days (difference, 0.65 hour). The mean sleep and wake times were at 11:02 PM and 6:41 AM, respectively, on workdays and 11:25 PM and 7:41 AM, respectively, on free days (differences, 0.23 hour for sleep time and 1.00 hour for wake time). With regard to sleep disturbances, 30.5% of adults experienced 1 hour or more of sleep debt,46.5% experienced 1 hour or more of social jet lag, 29.8% had trouble sleeping, and 27.2% experienced daytime sleepiness.

MedicalResearch.com Interview with: Maki Inoue-Choi, Ph.D., M.S., R.D. Staff Scientist Metabolic Epidemiology Branch National Institutes of Health MedicalResearch.com: What is the background for this study? Response: Tea is rich in bioactive compounds that can possibly protect against health conditions such as cancer and heart disease. A lower risk of death was seen among tea drinkers than non-drinkers in previous studies, but these were largely in populations where green tea drinking is common. In contrast, the studies in populations where black tea drinking is more common have been limited and the findings from these studies have been inconsistent. (more…)

MedicalResearch.com Interview with: Prof. John C. Mathers PhD Director, Human Nutrition Research Centre Director, Centre for Healthier Lives Population Health Sciences Institute Newcastle University Newcastle on Tyne UK MedicalResearch.com:  What is the background for this study?   Response: My colleagues and I have had a long-term interest in carrying out studies in people with hereditary cancer as a model for cancer in the general population. Here we studied people with Lynch syndrome who have an inherited defect in one of the genes encoding the DNA mismatch repair system. Because of this, they accumulate DNA damage faster than the general population and are prone to early cancers at several sites around the body. In the CAPP2 Study, we randomised almost 1000 people with Lynch syndrome to either resistant starch or to an ordinary corn-starch placebo. (more…)
Nutrition, Vegetarians / 06.06.2022

Vegetarianism is one of the biggest dietary trends. Many people are switching to this lifestyle choice to better their health, reduce their carbon footprint, and do their part in animal welfare. What’s more, many people don’t commit fully; some choose to enjoy meat-free days during the week or month instead. Thus, going vegetarian is more flexible and easier than you might have previously believed. Naturally, there are many health benefits of eating less meat; here, they will be discussed. (more…)

MedicalResearch.com Interview with: Dorothy Klimis-Zacas, MS, PhD, FACN Professor of Clinical Nutrition School of Food and Agriculture Graduate Faculty School of Biomedical Sciences Associate Faculty, Institute of Medicine Fulbright Fellow University of Maine Orono, Maine 04469  MedicalResearch.com:  What is the background for this study?  Response: Bioactive compounds such as polyphenols have been documented to have wound healing properties . In the Klimis-Zacas laboratory, phenolic extracts (PE) from wild blueberries (WB) were reported to promote angiogenesis in HUVEC cells via cell migration, angiogenesis, through VEGF/P13K/AKT pathway documented that the PE, primarily composed of chlorogenic acid significantly promoted cell migration and closure speed of wound by 38% above the control as well as angiogenesis and gene expression for proteins critical for cell movement while the anthocyanin fraction inhibited the above processes (5,6).  (more…)
Author Interviews, Endocrinology, Nutrition, Testosterone, Weight Research / 11.03.2022

MedicalResearch.com Interview with: Joe Whittaker, MSc Nutritionist MedicalResearch.com:  What is the background for this study?  Response: There are several studies showing a generational decline in men's testosterone levels, beginning in the 1970s. This is due to a variety of factors such as poorer diets, lack of physical activity, and increasing toxin exposure. Therefore, there is intense research interest in ways we can optimise testosterone levels, to combat this generational decline. Some well-known studies have found low-carbohydrate diets boost testosterone levels, but others have show the reverse effect. So, to settle the controversy we gathered and reanalysed all known studies on the topic. There was also the question of high protein diets and their effects on testosterone, which are currently disputed. (more…)
Author Interviews, Cancer Research, Nutrition, Supplements / 06.01.2022

MedicalResearch.com Interview with: Dr Rana Conway PhD RNutr  Research Fellow Energy Balance & Cancer Group, and Obesity Research Group Research Department of Behavioural Science and Health University College London    MedicalResearch.com: What is the background for this study? Response: We’ve seen great advances in cancer diagnosis and treatment in recent years which means the number of people living with and beyond a cancer diagnosis is rapidly increasing. The WCRF and CRUK recommend improving diet and exercise to reduce the risks of cancer coming back but we know anecdotally that supplements are sometimes seen as an easier option, and people who’ve had cancer are often interested to know if they should be taking any supplements.    (more…)
Author Interviews, COVID -19 Coronavirus, Johns Hopkins, Nutrition / 04.06.2021

MedicalResearch.com Interview with: Dr. Hyunju Kim Ph.D. Johns Hopkins School of Public Health MedicalResearch.com: What is the background for this study? Response: In the past few months, we have learnt that individuals with comorbidities (obesity, type 2 diabetes, cardiovascular disease, hypertension) are at higher risk of Covid-19. The etiology of these conditions is largely driven by poor nutrition and unfavorable lifestyle choices, yet no study examined whether dietary habits play a role in Covid-19 infection, severity of symptoms, and duration of illness.

MedicalResearch.com Interview with: Professor Elina Hypponen Professor in Nutritional and Genetic Epidemiology Director: Australian Centre for Precision Health University of South Australia MedicalResearch.com: What is the background for this study? Response: Diet is an important determinant of cardiovascular disease, and several studies have shown an association between high dairy and milk consumption with cardio-metabolic risk factors. Especially high fat dairy products can increase the risk of high cholesterol and cardiovascular disease by increasing the intakes of saturated fat and dietary cholesterol. However, milk is also a rich source of calcium and other nutrients, and evidence from randomized controlled trials has been inconsistent with respect to the role milk may have in cardiovascular health  (more…)
Author Interviews, Lancet, Nutrition, OBGYNE / 22.05.2021

MedicalResearch.com Interview with: Susan E. Carlson Ph.D. Associate Dean for Research Program Director,, AJ Rice Professor Department of Dietetics and Nutrition University of Kansas Medical Center Kansas City, KS MedicalResearch.com: What is the background for this study? What are its benefits? Response: DHA is an omega-3 fatty acid. Good food sources include some types of seafood (e.g., salmon, tuna, trout) and chicken eggs. Persons in the USA and in much of the developing world consume little dietary DHA. DHA supplements in pregnancy have been linked to lower risk of preterm birth for 20 years, especially early preterm births (<34 weeks gestation). For about 10 years, prenatal supplements with about 200 mg DHA have been readily available in the USA, however, no study has asked if this amount of DHA is optimal to reduce early preterm birth. Participants were given a supplement of 1000 mg or 200 mg DHA beginning before 20 weeks gestation using an adaptive randomization that periodically assigned more participants to the group with the fewest early preterm births.

Author Interviews, Cancer Research, Nutrition / 30.04.2021

MedicalResearch.com Interview with: Sa Kan Yoo MD PhD Division of Developmental Biology and Regenerative Medicine Kobe University, Kobe, Japan MedicalResearch.com: What is the background for this study? Response: Cancer is often considered as a disease of “overgrowth”. But, many known “cancer genes” in fact induce cell death rather than cell growth. Because of this phenomenon, it requires involvement of many genes, not a single “cancer gene”, for cells to become cancer. Although this protective phenomenon that cancer genes induce cell death has been known, its exact mechanism has remained unclear. We tackled this problem using the fruit fly, found its mechanism and discovered a way to manipulate it by dietary nutrition. (more…)
Author Interviews, Nature, Nutrition, Orthopedics, Pediatrics / 20.04.2021

MedicalResearch.com Interview with: Efrat Monsonego Ornan, Ph.D  Head of School of Nutritional Sciences Institute of Biochemistry and Nutrition The Robert H. Smith Faculty of Agriculture, Food and Environment The Hebrew University of Jerusalem MedicalResearch.com: What is the background for this study? Response: Food supplies in recent decades have been dominated by heavily processed, ready-to-eat products. Essentially, 75% of all world food sales are of processed foods. Over the past 30 years, children’s ultra-processed food intake has increased markedly, with 50% of the children in the US consuming these foods. Only in the US does UPF comprise 58% of energy intake, of which 90% is derived from added sugars. This reflects children’s excessive consumption of food and drink that are high in fat and refined sugars but do not provide appropriate levels of the proteins, vitamins and minerals required for growth. The negative health outcomes of excessive consumption of Ultra-processed food are well known, include obesity, metabolic syndrome and diabetes, and considered as the current world epidemic; the fact that children, during their postnatal development period (birth to adolescent), are the target of the Ultra-processed food industry is very disturbing in terms of public health. Bone development and growth are the characteristic phenomena of the childhood period. Yet, in spite of the huge importance of nutrition to bone development, the impact of Ultra-processed food consumption on skeleton development during childhood has never been studied directly, and this was the purpose of our study. To this end, we used young rats which are an excellent pre-clinical model for growth and fed them with either the recommended diet for their age or  a diet comprised of a typical Ultra-processed meal (a roll, hamburger, tomatoes, lettuce, ketchup and French fries) and a caloric soft drink.   (more…)
AACR, Author Interviews, Brigham & Women's - Harvard, Cancer Research, Nutrition, Prostate Cancer / 10.04.2021

MedicalResearch.com Interview with: Dr. Anna Plym PhD Postdoctoral Research Fellow Brigham and Women's Hospital Harvard T.H. Chan School of Public Health  MedicalResearch.com: What is the background for this study? What are the main elements of the healthy lifestyle? Response: Prostate cancer is the most heritable of all cancers, with genetic factors accounting for a large proportion of cases. Although we do not currently know about all the genetic factors contributing, a recent study identified 269 genetic markers for prostate cancer, validated in multiple independent populations (Conti et al., Nature Genetics 2021, Plym et al, JNCI, 2021: https://academic.oup.com/jnci/advance-article-abstract/doi/10.1093/jnci/djab058/6207974). Based on a polygenic risk score derived from these 269 markers, we observed that men with a high polygenic risk score have over a 50% risk of developing prostate cancer within their lifetime. With this excess risk in mind, we were interested in possible ways in which the genetic risk of prostate could be attenuated. An increasing number of studies have suggested that lifestyle factors can affect the risk of lethal prostate cancer – however, these studies have seldom incorporated genetic factors. We know from other diseases that a healthy lifestyle is of benefit for individuals at high genetic risk, and we hypothesized that this would be the case for prostate cancer as well. In this study, we examined a healthy lifestyle score for lethal prostate cancer consisting of six components: healthy weight (BMI < 30), not smoking (never smoked or quit > 10 years ago), vigorous physical exercise (3 or more hours per week), high intake of tomatoes or tomato-based products (7 servings or more per week), high intake of fatty fish (1 or more serving per week) and low intake of processed meat (less than 3 servings/week of beef or pork hot dogs, bacon, salami, bologna, or other processed meat sandwiches) (Kenfield et al, JCO, 2016).  (more…)

MedicalResearch.com Interview with: Nathorn (Nui) Chaiyakunapruk PharmD, PhD Professor, Department of Pharmacotherapy University of Utah College of Pharmacy  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Colorectal cancer is one of the cancers for which we found that the risk can be significantly reduced by modifying diet. Individual components of your diet can contribute to an overall healthy diet pattern to lower the risk of colorectal cancer or increase it. Strong scientific evidence shows that limiting red meat and alcohol consumption, eating foods containing fiber and calcium, consumption of dairy products especially yogurt can help prevent colorectal cancer.  (more…)
Alzheimer's - Dementia, Author Interviews, Cognitive Issues, Genetic Research, Nutrition / 11.12.2020

MedicalResearch.com Interview with: Auriel Willette, PhD Assistant Professor Food Science and Human Nutrition Iowa State University MedicalResearch.com: What is the background for this study? Response: To date, pharmacology therapies done to slow down or halt Alzheimer's disease have been inconclusive. Lifestyle interventions like changes in diet and activity are also mixed but do show some promise. Dietary clinical trials or self-reported diet have tended to focus on groups of foods such as the Mediterranean or MIND diet. To build from this excellent work, we were curious if we could pinpoint specific foods that were correlated with changes in fluid intelligence over time. Fluid intelligence represents our ability to creatively use existing knowledge, working memory, and other components of "thinking flexibly." Further, we tested if these patterns of association differed based on genetic risk. In this case, genetic risk was defined as having a family history of Alzheimer's disease or having 1-2 "bad" copies of the Apolipoprotein E (APOE) gene, which is the strongest genetic risk factor for Alzheimer's disease.

Author Interviews, BMC, Breast Cancer, Brigham & Women's - Harvard, Cancer Research, Diabetes, Nutrition / 10.12.2020

MedicalResearch.com Interview with: Tengteng Wang, PhD, MSPH, MBBS Postdoctoral Research Fellow Department of Epidemiology Harvard T.H. Chan School of Public Health Channing Division of Network Medicine Brigham and Women's Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Type 2 diabetes (T2D) has been associated with poor progression of breast cancer. Moreover, having a breast cancer diagnosis may also increase the risk of developing T2D. Therefore, identifying strategies for T2D prevention among breast cancer survivors may play a key role in improving their survival outcomes. One approach may be through a diabetes risk reduction diet (DRRD), a dietary pattern comprised of 9 components that has been associated with 40% lower T2D risk in a previous Nurses’ Health Study publication.1 However, no studies to date have evaluated the association between adherence to the DRRD (as measured by the DRRD score) and survival outcomes following breast cancer. In this prospective cohort study among 8,320 breast cancer survivors, we found that greater adherence to the diabetes risk reduction diet after diagnosis was associated with a statistically significant 31% lower risk of overall mortality. Reduced breast cancer-specific mortality was also observed, which was more pronounced (20% lower risk) among those who improved adherence after diagnosis compared to women with consistently low DRRD adherence before and after diagnosis.

MedicalResearch.com Interview with: Marie Bragg, PhD Assistant Professor, Department of Population Health on Health Choice NYU College of Global Public Health MedicalResearch.com: What is the background for this study? Response: We know from previous research that children who see food advertisements eat significantly more calories than children who see non-food advertisements. Those studies led the World Health Organization and National Academy of Medicine to issue reports declaring that exposure to food advertising is a major driver of childhood obesity. What we don’t know is how frequently unhealthy food and beverage brands are appearing in YouTube videos posted by Kid Influencers. Kid influences are children whose parents film videos of the child playing with toys, unwrapping presents, eating food, or engaging in other family-friendly activities. The parents then post the videos to YouTube for other children and parents to view for entertainment.  (more…)

MedicalResearch.com Interview with: Samia Mora, MD MHS Associate Professor, Harvard Medical School Director, Center for Lipid Metabolomics Brigham and Women’s Hospital Boston, MA 02215 @SamiaMoraMD MedicalResearch.com: What is the background for this study? Response: Couples, both married couples and domestic partners, are likely to share similar environmental exposures, adopt similar behavior patterns, and have similar characteristics. However, the degree to which couples share similar levels of cardiovascular (CV) risk factors and behaviors is uncertain. If high levels of poor CV risk factor measures and behaviors are common in both members of a couple, programs that target improvement of these risk factors and behaviors may simultaneously benefit CV health in both members of the couple.

Author Interviews, COVID -19 Coronavirus, Nutrition, Social Issues / 07.10.2020

MedicalResearch.com Interview with: Jason Nagata, MD, MSc Assistant Professor of Pediatrics University of California, San Francisco San Francisco, California, USA MedicalResearch.com: What is the background for this study? Response: During the COVID-19 pandemic, food insecurity is expected to rise given economic uncertainty and job losses. Vulnerable and marginalized populations are disproportionately affected by both COVID-19 and food insecurity. MedicalResearch.com: What are the main findings? Response: In this perspective, we argue that food insecurity and COVID-19 can exacerbate one another via bidirectional links. Experiencing food insecurity can lead to nutritional deficiencies and weakened host defenses, increasing susceptibility to COVID-19 infection. Food insecurity is also associated with chronic medical conditions which may lead to a higher risk of severe COVID-19 illness. Conversely, people with COVID-19 may not be able to work, generate income, or procure food while quarantined, which may worsen food insecurity. (more…)

MedicalResearch.com Interview with: David C. Montrose, Ph.D. Assistant Professor Department of Pathology Renaissance School of Medicine Stony Brook Cancer Center Stony Brook University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Rates of inflammatory bowel disease (IBD) have been increasing worldwide. In parallel with this, fructose consumption has increased. This study demonstrates that feeding high levels of fructose worsens intestinal inflammation in mouse models of inflammatory bowel disease (IBD). This fructose-induced worsening of disease is mediated through effects on gut bacteria. (more…)

MedicalResearch.com Interview with: Zhila Semnani-Azad, Ph.D. Candidate  Department of Nutritional Sciences Faculty of Medicine, University of Toronto Toronto, ON, Canada MedicalResearch.com: What is the background for this study? Response: Dietary fructose-containing sugars have been suggested to be an important contributing factor to increased metabolic syndrome risk. Several studies have consistently shown a strong association between sugar-sweetened beverages and increased incidence of metabolic syndrome. There is little information, however, on the role of other food sources of fructose-containing sugars in the development of metabolic syndrome. (more…)
Author Interviews, JAMA, Nutrition, Social Issues / 28.06.2020

MedicalResearch.com Interview with: Erin Brantley, PhD, MPH Senior Research Associate Department of Health Policy and Management Milken Institute School of Public Health Preferred pronouns: she/her/hers  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We looked at what happened when work requirements for the Supplemental Nutrition Assistance Program Participation, or SNAP, were turned on in many places after the Great Recession. We found large drops in participation in SNAP benefits due to work requirements, and that black recipients were more likely to lose benefits than white recipients. We think this is driven by the fact that black workers face higher unemployment rates than white workers, and work requirement policies do not take this into account. We also found that some people who report having disabilities lost benefits, even though the intent of work requirements is that they apply to people without disabilities.  (more…)
