MedicalResearch.com Interview with: Dr. Alexis C. Wood United States Department of Agriculture (USDA)/ARS Children’s Nutrition Research Center Baylor College of Medicine, TX MedicalResearch.com: What is the background for this study? Response: We know (we think!) that what we eat has a big influence on our health. However, discovering which foods influence our health, and how, is highly challenging. Research investigating this topic should be seen as an on-going process as new results and new study methods emerge, and as the food environment shifts. Red meat is often considered a food that should be minimized in diets designed to support good health. This may seem surprising as red meat is a good source of protein and many other nutrients, but the advice to limit red meat intake is based on several large-scale studies showing associations between red meat consumption and the development of conditions such as type 2 diabetes, and other cardiovascular disease risk related factors. However, newer research, with different designs or approaches, has struggled to conclusively support this association; for example, in studies where the amount of red meat in people’s diet is manipulated, we do not see the expected increases in risk. Other studies have suggested that any associations between red meat intake and chronic disease may reflect confounding effects by adiposity – that is, the increased risk of disease really reflects the increased risk associated with a higher BMI.

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.

MedicalResearch.com Interview with: [caption id="attachment_60498" align="alignleft" width="160"]Dr. Suneel Kamath MDGastrointestinal Oncologist Cleveland Clinic Dr. Kamath[/caption] Dr. Suneel Kamath MD Gastrointestinal Oncologist Cleveland Clinic Senior Author on this research       MedicalResearch.com: What is the background for this study? Response: Colorectal cancer rates in young people under age 50 are skyrocketing and have been for the last 3-4 decades. We really don’t understand why because most cases (probably around 70%) are not genetic or hereditary, just random, unfortunate events. We suspect that it is some exposure(s) like excess consumption of red meat, processed foods, sugar-sweetened beverages, excess antibiotic use altering the microbiome, rising incidence of obesity or some other factors. We really don’t know why yet. Our study used a technology called metabolomics, the study of breakdown products and production building blocks for our bodies, to look for differences in colorectal cancer in young people versus people that are older that developed colorectal cancer. Because metabolomics measures how each individual interacts with the exposures in our environment like diet, air quality, etc., it is a way to bridge the gap between our nature (determined by genetics) and nurture (determined by our exposures).

Response: Preserving memory and cognitive health is a high priority for most mid-life and older adults.  However, few strategies have been rigorously tested in randomized clinical trials and shown to have cognitive benefits. Nutritional approaches hold promise because the brain requires several nutrients for optimal health, and deficiencies in one or more of these nutrients may lead to accelerated memory loss and cognitive decline. The COcoa Supplement and Multivitamin Outcomes Study (COSMOS), a large-scale nation-wide randomized trial of multivitamins and cocoa flavanols had recently reported that multivitamins slowed global cognitive decline and memory loss (in COSMOS-Mind). The current study was a 2nd parallel trial, a collaboration between Brigham and Women’s Hospital and Columbia University, looking at a web-based assessment of the role of a  standard multivitamin and of cocoa flavanols in slowing age-related memory loss. The report in AJCN is on the multivitamin-cognition findings. The multivitamin tested was Centrum silver for adults (without iron).

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.

Martens PhD Assistant Professor Director, Delaware Center for Cognitive Aging Research Department of Kinesiology & Applied Physiology University of Delaware Newark, DE MedicalResearch.com: What is the background for this study? Response: One of the main issues with Alzheimer's disease is an impaired ability to make energy in the brain. NAD+ is critically involved in the creation of energy within cells and there is strong evidence that nicotinamide riboside (NR), a precursor to NAD+, can restore brain function in mice that exhibit similar characteristics as people with Alzheimer's disease. We had previously studied the effects of NR in healthy older adults and wanted to see whether it is even capable of getting into brain tissue. We used remaining blood samples from our original study and measured the amount of NAD+ within tiny "vesicles" in the blood that we are quite confident originated from the brain and other neural tissue

Response: Our research team has been researching the roles of environmental and genetic determinants of chronic diseases for nearly three decades, with special emphasis on evaluating micronutrients, minerals, and trace elements in relation to cardiometabolic outcomes, and findings of which have contributed to the design of several large, randomized trials of dietary supplements in the US (Liu JAMA 1999; 2011; Diabetes Care 2005a,b; Diabetes 2006).  Several large intervention trials have consistently shown beneficial effects on clinical cardiometabolic outcomes of a diet pattern rich in micronutrients, although research on micronutrient supplementation has mainly focused on the health effects of a single or a few vitamins and minerals. We decided to take a comprehensive and systematic approach to evaluate all the publicly available/accessible studies reporting all micronutrients including phytochemicals and antioxidant supplements and their effects on cardiovascular risk factors as well as multiple CVDs.

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.

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.

Chan School of Public Health Dr. Shan[/caption] 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.

Response: As the population is living longer, there is increased risk of frailty and vulnerability. Frailty is defined as reduced physiological reserve and decreased ability to cope with even an acute stress. Up to half of adults over the age of 85 are living with frailty and preventative measures are greatly needed. We tested the effect of vitamin D and marine omega-3 fatty acid supplementation on the risk of developing frailty in healthy older adults in the US enrolled in the VITamin D and OmegA-3 TriaL (VITAL) trial.

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.

MedicalResearch.com Interview with: James Webster PhD Lead author Nutritional Epidemiology Group, University of Leeds MedicalResearch.com: What is the background for this study? Response: Hip fractures are the most severe consequence of osteoporosis and are a major public health problem. There are growing concerns of poor bone health and higher risk of fractures in vegetarians, but prospective studies comparing risk of hip fracture in vegetarians and meat-eaters over time are scarce and limited. A study of British men and women in the EPIC-Oxford cohort showed a greater risk of hip fracture in pescatarians, vegetarians, and vegans compared to meat-eaters. The only other study on the topic, the Adventist Health Study of US adults, found no clear evidence of a difference in hip fracture risk between vegetarians and meat-eaters, but identified hip fractures through questionnaires, which are susceptible to selective loss to follow-up. To build on previous research, we investigated the risk of hip fracture in occasional meat-eaters, pescatarians, and vegetarians compared to regular meat-eaters in middle-aged UK women, who are at a greater risk of hip fracture than men, with hip fractures accurately confirmed using objective and complete hospital records.

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.

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.

Sesso, ScD, MPH Associate Professor of Medicine Division of Preventive Medicine Brigham and Women's Hospital MedicalResearch.com:  What is the background for this study? How does the amount of flavanols in the study arm compare to what might be obtained in a typical diet? Response: The COcoa Supplement and Multivitamin Outcomes Study (COSMOS) is a randomized, double-blind, placebo-controlled clinical trial that tested the effects of two promising dietary supplements on cardiovascular disease (CVD) and cancer in 21,442 older adults. Cocoa flavanols have been shown to have favorable vascular effects in small and short-term clinical trials. The 500 mg/day flavanols tested in COSMOS exceeds that readily obtained in the diet typically from cocoa, tea, grapes, and berries. Of note, flavanol content in not typically listed on food labels. COSMOS also tested a multivitamin, the most common dietary supplement taken by US adults and previously linked with a potential modest reduction in cancer in a previous long-term trial of men conducted by our research group at the Division of Preventive Medicine at Brigham and Women’s Hospital.

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.   Joe Whittaker, MSc[/caption] 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.

Bohórquez PhD Associate Professor in Medicine Duke Institute for Brain Sciences Durham, NC MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: In 2018, my laboratory discovered that a cell type in the gut epithelium synapses with the vagus nerve, the nerve which connects the gut and the brain. These gut cells are called neuropod cells. Neuropod cells transduce sugar within milliseconds using the neurotransmitter glutamate. Since then, we have been interested in defining how this rapid communication between neuropod cells and the brain regulates behavior. – Diego Bohórquez Over a decade ago, it was shown that the gut is the key site for discerning sugar and non-caloric sweetener. But the specific cell in the gut that underlies this effect was unknown. – Kelly Buchanan

Response: Dynamic visual acuity refers to the ability to detect and perceive small details in objects that are moving relative to an observer.  Dynamic visual acuity is a complex visual function, that involves a number of different aspects of vision, including detecting the target, moving the eyes appropriately to observe the target, and processing the visual information from the target in the brain to interpret what we are seeing.   What makes dynamic visual acuity so interesting to study, is that as a visual function, it appears to play an important role in a number of real-world situations, including playing sports, driving, and piloting, and it may provide us more information about how the visual system is functioning compared to the more traditional, static vision tests alone. Previous research has demonstrated that consumption of caffeine has been shown to benefit physiological, psychomotor, and cognitive performance.  More recently there has been an increased interest in studying the impacts of caffeine on the vision system, however the impact of caffeine on dynamic visual acuity has not been studied.  This study was designed to address this limitation in the literature, particularly because dynamic visual acuity appears to be such an important visual function for real-world activities.

The American College of Obstetricians and Gynecologists (ACOG) recommends that pregnant women limit their caffeine consumption to <200 mg/d out of an abundance of caution due to potential associations with pregnancy loss and fetal growth restriction at higher intakes. There remains limited data on associations with maternal cardiometabolic outcomes in pregnancy.

Response: There is clear evidence from the literature that sodium reduction or potassium supplementation can reduce blood pressure. Reduced blood pressure can also lead to a risk reduction for cardiovascular diseases. Salt substitute is a reduced sodium added potassium product combined those effects. Previous research of salt substitute focus on the blood pressure outcome. There is no evidence if salt substitute can reduce the risk of cardiovascular diseases or pre-mature death. This study provided a definitive evidence for this unaddressed question. MedicalResearch.com: What are the main findings? The main findings of the research were:
  • The salt substitute reduced the risk of stroke by 14%
  • The salt substitute reduced the risk of major adverse cardiovascular events by 13%
  • The salt substitute reduced the risk of pre-mature death by 12%

MedicalResearch.com: What is the background for this study? Response: We and others have shown that not only “what” but also “when” we eat relates to obesity and weight loss
  • Meal timing can influence circadian rhythms and eating a high energy and high sugar food, such as chocolate, either at night or in the morning may have a different effect on the circadian system, and consequently on body weight and metabolism.
  • Milk chocolate has a name for contributing to weight gain due to its high fat, sugar and caloric content. Chocolate eating habit has been associated with long-term weight gain especially in postmenopausal females who are particularly vulnerable to weight gain.
