Associations between omega-3 fatty acid-derived lipid mediators and markers of inflammation in older subjects with low-grade chronic inflammation.

Prostaglandins Other Lipid Mediat

January 2025

Cardiovascular Nutrition Laboratory, Jean Mayer USDA Human Nutrition Research Center on Aging and Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy, Tufts University; Boston, MA, 02111. Electronic address:

Cardiovascular disease (CVD), the leading cause of death in the United States and globally, is a chronic inflammatory disease likely caused by an impaired ability to resolve inflammation. Pre-clinical studies have provided strong evidence of the activating role of specialized pro-resolving lipid mediators (SPMs) derived from the omega-3 fatty acids eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA) and docosaheaxaenoic acid (DHA) on the resolution of inflammation. However, there is a dearth of information on the role of SPMs on inflammation in humans.

December 2024

Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy, Tufts University, Boston, MA, United States.

The urgent need to address both human and environmental health crises has brought attention to the role of food systems in driving climate change, biodiversity loss, and diet-related diseases. This paper explores the intersection of Food is Medicine (FIM) and regenerative agriculture (RA) as an emerging approach with the potential to help address the interconnected challenges of human and ecological health within healthcare and food systems. FIM programs, such as produce prescriptions and medically tailored meals, aim to improve health outcomes by increasing access to nutritious foods and promoting nutrition equity.

People have known that El Niño events are associated with low rainfall in Southern Africa for a century, and seasonal rainfall forecasts are now available in agricultural advisories for farmers. While there is abundant theory as to how farmers might (or should) use seasonal rainfall information on their farms, little is known about whether this information has been widely used or has had widespread benefit. In this study, we use subnational data on cropping area and yield to see if we can detect any macro-level patterns in agricultural choices or outcomes that are related to knowledge of the El Niño Southern Oscillation or seasonal forecast information in Southern Africa.

Food insecurity and pediatric HIV: patient perspectives on clinical solutions.

AIDS Care

December 2024

Department of Pediatrics, Division of Pediatric Palliative Care, Emory University, Atlanta, GA, USA.

Food insecurity is a prevalent social determinant of health for people living with HIV and is associated with suboptimal treatment outcomes. While clinic-based efforts to address food insecurity have increased over the past decade, few studies have explored the perspectives of paitents and caregivers managing chronic illnesses such as HIV. Caregiver insights are particularly critical in pediatric HIV care, where caregivers often play a central role in screening and referral processes.

Dietary prevention of antibiotic-induced dysbiosis and mortality upon aging in mice.

FASEB J

December 2024

Jean Mayer USDA Human Nutrition Research Center on Aging, Tufts University, Boston, Massachusetts, USA.

Article Synopsis
  • Oral antibiotic use in older adults can disrupt gut microbiota, leading to health issues like infections and chronic diseases.
  • A study involving mice showed that those on a high glycemic diet with antibiotics had significantly lower survival rates due to severe gut damage, unlike those on a low glycemic diet.
  • The low glycemic diet helped maintain a healthier gut microbiome and preserved important bacterial functions, suggesting it could be a helpful strategy to prevent gut issues caused by antibiotics.

Applying Community-based System Dynamics to promote child health equity: the case of healthy and fit kids in Milwaukee, WI.

Front Public Health

November 2024

ChildObesity180, Friedman School of Nutrition Science and Policy, Tufts University, Boston, MA, United States.

Background: Child health equity is influenced by complex systemic factors, including structural racism, socioeconomic disparities, and access to resources. Traditional public health interventions often target individual behaviors, but there is a growing need for systems approaches that address these root causes. This study examines coalition members' perspectives on promoting child health equity in Milwaukee as a result of participating in an intervention that includes Community-based System Dynamics (CBSD).

Differential regulation of brain microvessel transcriptome and brain metabolome by western and heart-healthy dietary patterns in Ossabaw pigs.

Sci Rep

November 2024

Cardiovascular Nutrition Laboratory, Jean Mayer USDA Human Nutrition Research Center on Aging, Tufts University, 711 Washington Street, Boston, MA, 02111, USA.

Diet is a potentially modifiable neurodegenerative disease risk factor. We studied the effects of a typical Western diet (WD; high in refined carbohydrates, cholesterol and saturated fat), relative to a heart-healthy diet (HHD; high in unrefined carbohydrates, polyunsaturated fat and fiber, and low in cholesterol) on brain microvessel transcriptomics and brain metabolomics of the temporal region in Ossabaw minipigs. Thirty-two pigs (16 male and 16 females) were fed a WD or HHD starting at the age of 4 months for a period of 6 months.
