These issues range from obesity to food insecurity, with the unit of analysis ranging widely from families to neighborhoods to governments. Causes for inadequate nutrition are multiple and complex, resulting from biological, economic, social, cultural,and policy issues. Implications of community nutrition issues include poor health and disease.

The program seeks to influence community issues and behaviors by conducting rigorous community-based research; leading community outreach and engagement initiatives; and teaching and mentoring students.

Our faculty members are interested generally in the following areas:

  • designing, implementing and evaluating nutrition interventions and policies, in particular for limited resource and under-served populations
  • understanding people’s food choices and the contributions of social, cultural, policy, and food systems to those behaviors
  • understanding the distribution and causes of nutritional disparities in populations using tools from epidemiology, social sciences, systems science,and policy analysis

Their research interests  cover a wide range of topics.

Graduate Study: Although the program is based within the Division of Nutritional Science, you may take courses across the university to meet your educational focus. To pursue this concentration, you will need a solid understanding of the biological as well as the social basis of human nutrition and health, along with the ability to apply social science theory and methods to work with groups and populations to address nutrition issues. You will also need substantive experience related to community research and/or engagement.

You will be expected to take courses that recognize the social, psychological, cultural, agricultural, economic, clinical, and public health policy determinants of nutrition and health as well as courses that provide you with expertise in the analytic and conceptual methods to address these issues.

Opportunities After Graduation: Doctoral graduates typically work for universities, government agencies such as the National Institutes of Health and the Centers for Disease Control and Prevention, and applied research institutions. Students who earn a master’s degree often work for public health, Cooperative Extension, community agencies,and educational institutions.

In this concentration, you will study how variations in individuals’ nutritional status affect their health and functioning. Faculty members are focused primarily on developing safe and effective methods for improving the human condition. In general, they are interested in the following:

  • maternal, infant and child nutrition
  • control of food intake and regulation of body weight,as well as animal models of obesity
  • factors that affect the absorption, metabolism and storage of Vitamin A, as well as the association between Vitamin A deficiency and disease
  • effects of nutritional alterations —for example, iron deficiency folate alterations and PUFAs—on mortality, work capacity,and behavior and cognitive functioning
  • lasting cognitive effects of early exposure to environmental toxins, such as lead and methylmercury, including exposure via breastmilk
  • metabolism, bioavailability and biological effects of Vitamin E, including mechanisms of regulation of Vitamin E status

Our faculty’s research interests  cover a wide range of topics.

Graduate Study : Although the program is based within the Division of Nutritional Science, you may take courses across the university to meet your educational focus. To pursue this concentration, you will need a solid understanding of the biological basis of human biology, nutrition, health and disease,and statistics.

Opportunities After Graduation : Graduates of this program typically work in universities, such government agencies as the National Institutes of Health and the Centers for Disease Control and Prevention, and the food and health industries.

In this concentration, you will explore malnutrition and hunger, which are widespread in many developing countries, as well as chronic disease resulting from poor nutrition.

The causes of inadequate nutrition can be complex, encompassing biological, economic, social and political issues. Program faculty members address nutritional problems through research, nutritional education and training; applied nutrition programs in the community, government, and international organizations; and institutional development.

Graduate Study : This concentration is dedicated to training committed professionals whose previous training and international experience provide a solid foundation for benefiting from Cornell's rigorous intellectual environment. Our faculty members have had experiences in many parts of the world, and their expertise covers the spectrum from basic biology to population-based interventions. You may take courses in political, economic, sociological, clinical and public health dimensions of nutrition. You will need a solid foundation in the biological aspects of nutrition and your academic background should include biochemistry, physiology and laboratory methods.

Opportunities: Students graduating from this program work for government ministries and other action agencies such as UNICEF and nongovernmental organizations; agencies that deliver technical assistance such as the U.S. Agency for International Development and the World Health Organization; and applied research institutions and universities. 

In this concentration, you will investigate the basic biological processes in nutrition and nutrition’s roles in health and disease. The concentration integrates a range of disciplines including chemistry, biochemistry, biophysics, cell biology, genetics, neurobiology, and developmental and reproductive biology. A flexible curriculum will enable you to tailor your academic programs to your academic background, research interests, and career plans.

The research opportunities, using such methodologies as classical biochemistry, transgenics and mass spectrometry, are extensive and diverse:

  • Nutritional biochemistry studies the biochemical, metabolic, physiological and epigenetic functions and properties of nutrients and other dietary constituents. The discipline is used to examine the synergistic relationships among diet, health and disease susceptibility. Students take an integrative curriculum in nutritional biochemistry and may take foundation courses in the basic biological, chemical and physical sciences. Most students complete a minor in biochemistry or molecular biology.
  • Nutrition genomics examines the role of nutrients and dietary components in regulating genome structure, expression and stability, as well as the role of genetic variation on individual nutrient requirements. Research in nutritional genomics relies on genetic technology and models. It includes developing and using transgenic mice, microarray technologies for expression profiling, and human population genetics. Most students complete a minor in genetics.
  • Nutritional metabolomics studies the regulation of metabolic pathways and networks by nutrients and other food components, as well as the establishment of analytical methods that profile human serum and urinary metabolites to assess nutritional imbalances and disease risk. Most students complete a minor in biochemistry or molecular biology.
  • Maternal nutrition/fetal development/epigenetics  looks at the molecular-level relationships between maternal nutrition and fetal development. Research topics include how maternal nutritional status regulates fetal gene expression (metabolic imprinting) and how to identify the consequences of such imprinting throughout the life of the offspring.

Opportunities after Graduation: Graduates of this program typically follow careers in research and academics. They may work in universities, private research institutions, government and private industry.

The mission of the Division of Nutrition is to investigate, translate and disseminate the benefits of a healthy eating pattern on prevention of disease across the life span. This involves clinical interventions and large observational studies that aim to identify key nutritional factors contributing to health and underlying mechanisms that inform relevant dietary interventions. Through undergraduate, graduate and continuing medical nutrition education, we strive to train and prepare competent healthcare providers to implement science-based nutrition principles throughout their own practices and research careers. 

A healthy eating pattern initiated early in life and sustained throughout life offers a powerful approach to prevention of chronic disease. Growing evidence nationally and globally documents the benefits of a diet rich in produce, whole grains, nuts, legumes, fish, unsaturated fats, oils and dairy products that extend the quality of life years and reduce the global burden of disease. Our research aims to implement these dietary recommendations and study the mechanisms underlying their biological impact.”

Introduction: Nutrition is critical to gastrointestinal (GI) disease prevention and treatment, including operations, yet perioperative nutrition practices vary widely. We aimed to understand GI surgical patient and healthcare provider perioperative nutrition beliefs and practices. 

Methods: We used a mixed methods approach including a patient survey (n=19), provider survey (n=26), and semi-structured interviews with a subset of providers (n=15). Providers included surgeons, gastroenterologists, medical oncologists, advanced practice providers, and dietitians. Provider interviews were transcribed, iteratively coded, and thematically analyzed. Quantitative and qualitative data were integrated. 

Results: 94.7% of patients and 100% of providers surveyed believe that nutrition affects outcomes. Patients seek nutrition information from diverse resources (73.7% from websites/blogs, 42.1% from documentaries, 36.8% from books/magazines) and people (52.6% from family members, 42.1% from a significant other/partner/spouse, 36.8% from a dietitian/nutritionist). Providers cited lack of quality information, misinformation, and inconsistency among healthcare providers as barriers to high-quality nutrition care. Both patients and providers noted that nutritional supplements have drawbacks, with 100% of patients and 96.2% of providers expressing interest in house made plant-based protein smoothie or soup alternatives. 

Conclusion: This study led to the development of a multidisciplinary task force which has collaborated on multiple interventions to improve inpatient perioperative surgical nutrition (e.g. smoothie pilot and postoperative menu revisions).

Editorial on the Research Topic Role of nutrition in skeletal muscle atrophy and sarcopenia

Approximately 40%–50% of the body mass consists of skeletal muscle, which is important for human energy metabolism. Its quality and functional integrity are crucial to maintaining the normal function and metabolic homeostasis of the musculoskeletal system ( 1 ). Muscle atrophy reduces strength and endurance, which restricts activity, decreases the quality of life, increases the risk of falls and fractures, and starts a vicious cycle of muscle disuse that exacerbates muscle weakness and loss. The atrophy of skeletal muscle has various causes, including aging, cancer, metabolic diseases, sepsis, bed rest, and denervation ( 2 ). Sarcopenia, known as the most prevalent type of skeletal muscle atrophy in humans, is primarily associated with aging. Notably, as the aging of the global population continues to deepen, sarcopenia has become a serious public health problem, causing huge direct or indirect socioeconomic burdens ( 3 ). Limited success has been achieved in clinical trials testing therapeutics against skeletal muscle atrophy and sarcopenia ( 4 ). Therefore, finding dietary approaches for the prevention and treatment of muscle atrophy and sarcopenia has been a research hotspot in the fields of nutrition, medicine, and biology.

Highly dynamic, skeletal muscle reacts to a variety of stimuli, particularly mechanical load variations. The main cause of muscle atrophy in healthy individuals is muscular disuse, which also impacts protein expression, metabolism, skeletal muscle phenotype, and morphological features ( 5 ). Decreased physical activity is mostly due to reduced ambulatory activity, lockdowns imposed, illnesses necessitating bed rest, or discomfort or impairments from chronic conditions. Spinal cord injury is a severe, incapacitating condition that causes skeletal muscle innervation loss, lower motor function, and considerably reduced skeletal muscle load, leading to atrophy ( 6 ). Xu et al. indicated that oxidative stress injury and inflammation represented the primary mechanisms of skeletal muscle atrophy following spinal cord injury. This included various pathways, including the autophagic lysosome system, the ubiquitin-proteasome system, the IGF-1/PI3K/Akt/mTOR signaling pathway, and the hypothalamus-growth hormone-IGF-1 axis ( Xu et al. ).

Inflammation is essential to the pathology of illnesses linked to dysfunctional skeletal muscles ( 7 ). A number of illnesses, such as chronic obstructive pulmonary disorder (COPD) and asthma, are marked by persistent inflammation or an increase in inflammatory mediators. Even though the pathologies of these disease states vary, they are all characterized by skeletal muscle mass loss and physiological disruption. Pro-inflammatory cytokines play a major role in the chronic inflammation that characterizes several of these diseases ( 8 ). The data from 3,389 participants in the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2006 and 2011 to 2018 showed a significant positive association between the risk of sarcopenia in asthmatic patients and their dietary inflammatory index levels, as reported by Lin et al. Therefore, decreasing the intake of these pro-inflammatory elements may help prevent sarcopenia. To understand the function of nutrition in patients with coexisting COPD and sarcopenia, Nan et al. summarized the intrinsic mechanisms of both conditions.

Diet is an important determinant of skeletal muscle atrophy. Muscle atrophy can be caused by a variety of dietary variables, including insufficient protein consumption, vitamin D deficiency, and a diet low in antioxidants and long-chain polyunsaturated fatty acids ( 9 ). After screening data selected from the 2011–2014 NHANES, including 6,019 American adults, Wu et al. showed that the composite dietary antioxidant index and the dietary antioxidants zinc, vitamin E, and selenium were significantly correlated with handgrip strength in males, while only zinc was related to handgrip strength among dietary antioxidants in females. Additionally, eating a diverse range of foods can lower the risk of unfavorable health outcomes like physical dysfunction and death. Dietary diversity score refers to the number of various foods or food groups within a specific timeframe, where higher scores signify a broader range of foods consumed. Using the data from 6,624 older Chinese adults, Du et al. showed that sarcopenia risk was lower in those with higher dietary diversity scores for the total diet, animal-based diet, and plant-based diet. Therefore, consuming a diverse range of foods is crucial for maintaining bodily function ( Du et al. ).

In summary, this Research Topic provides the most recent information on the impact of diets or dietary components on skeletal muscle atrophy and sarcopenia while updating the molecular mechanisms that mediate and orchestrate muscle mass loss in disease. It offers new insights into the possible strategies for the management and prevention of these conditions. Meanwhile, due to the complex pathogenesis of skeletal muscle atrophy and existing inter-individual variability, precise nutrition for individuals with skeletal muscle atrophy will be a future research trend.

Nutrition as medicine: The building blocks of health – cooking

  • Written by Karen Burbach, UNMC strategic communications
  • Published May 3, 2024

What we eat matters.

Yet, too often, fast and ultra-processed foods are America’s go-to option.

Nutrition as medicine

The food: Diet, healthy or otherwise, can impact an individual’s health, making nutrition a larger part of today’s medical education and care.

The cooking: Pairing healthy cooking with nutritional info and meal prep tips is a recipe for success at UNMC, where wellness and well-being are top of mind.

The recipes: For a healthier, more cost-effective option, skip takeout and prepare a dish from scratch at home. Here are two enticing options.

Now, Steven Wengel, MD, assistant vice chancellor for wellness at UNMC, is partnering with others to promote healthy eating through healthy cooking.

“How much we move and eat matter dramatically,” Dr. Wengel said. “This project is intended to provide a healthy cooking lesson that is practical for busy people and pleasing to the palate.”

phd in nutrition medicine

In 2020, Dr. Wengel helped launch “Keep Calm and Cook On,” a series of virtual presentations for UNMC faculty, staff and students that includes a cooking demonstration, nutritional information and a question-and-answer session.

Supported by The Monarch Fund, the project is a joint effort of UNMC Human Resources, UNMC’s wellness program and medical nutrition staff, and the Metropolitan Community College Institute for the Culinary Arts’ Open Kitchen Workshops. In addition, UNMC’s food services partner, Sodexo, features limited menu items at its med center cafes.

Dr. Wengel credits MCC’s Brian O’Malley and Sara Rogers for their culinary collaboration, UNMC’s Mariah Jackson, assistant professor of medical nutrition, for providing nutritional highlights during each demonstration, and HR’s Giovanni Jones for her creativity and logistical help.

Participants learn how to prepare healthy (and easy!) recipes that don’t require hours in the kitchen or long lists of costly ingredients. Past presentations have focused on preparing Minnesota wild rice soup, lemon chicken orzo and turkey and black bean chili.

“More and more research is being done on the negative effects of ‘ultra- processed food’ on our health,” Dr. Wengel said. “One antidote for that is cooking at home using healthy ingredients.”

A geriatric psychiatrist, Dr. Wengel said growing evidence suggests lifestyle factors may impact and help prevent such diseases as Alzheimer’s. “More and more, we’re seeing that lifestyle factors — like how much you move and what you eat — matter,” he said.

In addition, reports indicate that some psychiatric conditions — obsessive compulsive disorder and major depression — are associated with derangements of the microbiome, he said. “We don’t know if it’s cause or effect,” Dr. Wengel said, “ …but in some preliminary studies, the microbiomes of people with depression or OCD seem to be different. Can we influence that by diet? We don’t know, but maybe.”

One thing we do know, he said: “There’s no downside to eating healthy.”

Roel Verhaak, PhD, in honor of Brain Tumor Awareness Month

Roel verhaak, phd.

What inspires you as a scientist and working to find better treatments for gliomas?

I have lost a dear friend to this disease. She inspires me every day to come to the lab, and work towards better treatment outcomes for glioma patients and their families.

What are the challenges in studying brain tumors? Recent discoveries you are excited about?

The biggest challenge is the time it takes to go from a discovery in the lab to a clinical study. I am excited about a new drug called vorasidenib, which was reported last year to improve survival in patients with an IDH-mutant glioma. The target for vorasidenib was first discovered in 2008, yet it took 15 years to get to this point. And that was relatively fast!

As we honor Brain Tumor Awareness Month, what are you most hopeful for in terms of the future treatment of brain tumors?

The recent success with vorasidenib shows that there is hope for brain tumor patients, that we are able to develop new treatments that make a difference. We need to find more of those!

Vanguard graduate, looking to study the brain, has cross-cultural medicine in mind

Vanguard University graduate Dyane Velazquez poses on campus on Wednesday.

  • Show more sharing options
  • Copy Link URL Copied!

Dyane Velazquez graduated from Vanguard University on Thursday morning, one of hundreds of graduates at the commencement ceremony at Mariners Church in Irvine.

Velazquez looks forward to a bright future. The Santa Ana native is a first-generation Mexican American who graduated summa cum laude — and a semester early at that — with a degree in biology, concentration in neurobiology and minor in chemistry.

She wants to go to medical school and become a pediatric neuro-oncologist, studying the brain. One thing on Velazquez’s brain this week is a statistic she heard recently.

Less than 3% of the doctors in this country are Latina like her, she said.

“Having even just that dream in mind is quite significant, I feel, making a difference and providing comfort to patients that would prefer speaking in Spanish,” she said. “It’s just about making a difference.”

Dyane Velazquez, center, with her mother, whom she calls her No. 1 supporter.

Of the 542 graduates on Thursday, 35% were first-generation college graduates like Velazquez. She remembers when she was attending high school at Orange County School of the Arts, doing things herself like filling out her financial aid forms, applying for college or speaking to her counselor.

Still, her mom Ary Herrera has been there for her every step of the way.

“She’s been my No. 1 supporter forever,” Dyane Velazquez said, fighting back tears. “If I wanted to do something, I wanted to achieve something, she was the one who would say, ‘You’ve got this, and I’ll be right there next to you supporting you.’ She’s been my rock.”

Dyane’s accomplishments have been considerable since enrolling during the coronavirus pandemic in fall 2020. She became the school’s first student Spanish translator, both at live events and for the school’s newsletter and website. These were among extensive experiences that also included time as an organic chemistry tutor, COPE Health Scholar at St. Joseph Hospital and a Youth4Vaccines Ambassador at an online forum with Dr. Anthony Fauci in 2021.

The latter opportunity was provided by her main mentor, Vanguard biology professor Dr. Itzel Calleja-Macias.

“Coming here was a really good decision,” said Velazquez, who was a Presidential Scholarship recipient. “I created really good bonds with my professors, my classmates, gained so much good knowledge about something that I’m really passionate about, biology, especially learning about the brain.”

Dyane Velazquez served as a UCI Health volunteer in the Watanabe Latoratory.

Vanguard aced enrollment for first-time, full-time Latino undergraduate students like Velazquez, according to a recent report from the Education Trust . The university is doubling down on efforts to attract and support local students, with 85% of students coming from within a 100-mile radius of the Costa Mesa campus.

Additionally, 51% of undergraduates are eligible for the federal Pell Grant, typically given to students who display exceptional financial need.

Dr. Renea Brathwaite , the school’s Chief Diversity Officer and Dean of the School of Theology and Ministry, understands first-hand Velazquez’s point about how the language barrier can make a difference in the doctor’s office. He grew up in the Caribbean until the family moved to New York.

“Even though we spoke English, New York English and Barbadic English are not the same,” Brathwaite said with a laugh. “When I found a Caribbean doctor, a child of Caribbean people, instantly he made sense to me and I made sense to him. It’s not just a myth that people have better medical outcomes when their doctors understand them.”

The school supports its Latino students with resources like the Jesse Miranda Center for Hispanic Leadership . In 2015, Vanguard was the second university in Orange County to be a federally designated Hispanic Serving Institution.

Dyane Velazquez attends the Vaccine Month Kick Off in June 2021 featuring Dr. Anthony Fauci, held by the White House.

Last year, the college unveiled the Patty Arvielo School of Business and Management , the first business school in the country to be named after a Latina.

Brathwaite said the university has to deal with not only systemic barriers, but interpersonal as well.

“We do have to work on building up the confidence and academic skills of our students, and the ability for students to engage cross-culturally,” he said. “Three percent, that means you’re going to schools where most of your professors are not going to look like you. You have to know how to engage cross-culturally when there is a power differential. That’s the reality, until there comes a time when we have much better representation.”

Velazquez was more than excited to graduate. Her dream medical school is UC Irvine, where she already has worked with Dr. Momoko Watanabe through the Summer Institute in Neuroscience program funded by the National Science Foundation.

Velazquez knows that at Vanguard, she was more than just a statistic. A school slogan is “Your story matters,” and hers is compelling.

“It is a small campus, but it’s like a family,” she said.
