- Precision nutrition is an emerging concept that aims to develop nutrition recommendations tailored to different people's circumstances and biological characteristics. Responses to dietary change and the resulting health outcomes from consuming different diets may vary significantly between people based on interactions between their genetic backgrounds, physiology, microbiome, underlying health status, behaviors, social influences, and environmental exposures. On 11-12 January 2021, the National Institutes of Health convened a workshop entitled "Precision Nutrition: Research Gaps and Opportunities" to bring together experts to discuss the issues involved in better understanding and addressing precision nutrition. The workshop proceeded in 3 parts: part I covered many aspects of genetics and physiology that mediate the links between nutrient intake and health conditions such as cardiovascular disease, Alzheimer disease, and cancer; part II reviewed potential contributors to interindividual variability in dietary exposures and responses such as baseline nutritional status, circadian rhythm/sleep, environmental exposures, sensory properties of food, stress, inflammation, and the social determinants of health; part III presented the need for systems approaches, with new methods and technologies that can facilitate the study and implementation of precision nutrition, and workforce development needed to create a new generation of researchers. The workshop concluded that much research will be needed before more precise nutrition recommendations can be achieved. This includes better understanding and accounting for variables such as age, sex, ethnicity, medical history, genetics, and social and environmental factors. The advent of new methods and technologies and the availability of considerably more data bring tremendous opportunity. However, the field must proceed with appropriate levels of caution and make sure the factors listed above are all considered, and systems approaches and methods are incorporated. It will be important to develop and train an expanded workforce with the goal of reducing health disparities and improving precision nutritional advice for all Americans.

- Creating nutritious and ecologically regenerative food cultures depends on the local knowledge of food system laborers. Food producers in small island developing states center socioecological interdependence in their livelihoods and, as such, conserve biocultural diversity. Amid burgeoning health, economic, and climate crises brought on by colonialism, reclaiming food sovereignty requires a critical and embodied scientific approach, one that considers what traditional ecological knowledge is and who creates and sustains it. This study positions laborers as the primary sources of knowledge in island food systems; discusses declines in nutrition and agrobiodiversity as consequences of food labor loss; and proposes laborers' stewardship as essential to regenerating self-determination. Using critical quasi-ethnographic methods, this report synthesized primary data from narrative interviews in Guam (Guåhan, n = 13) and Puerto Rico (Borikén, n = 30), two former colonies of Spain and current territories of the United States, as specific examples of place-based knowledge production, interwoven into critical discussion of broader literature in this space. Our findings show that local food laborers combine intergenerational, ecosystem-specific knowledge with robust human value systems, negotiating across competing economic, cultural, and ecological needs to sustain livelihoods and regenerate biodiversity. As well-connected nodes in family and community networks, laborers serve as the scaffolding on which compassionate and relational care can thrive. Trade policies and the market dominance of transnational food corporations have severely reduced local food production in favor of food import dependence in islands, aggravating labor shortages and augmenting food insecurity. Through waves of out-migration and cash remittance, social care relationships have become monetized, reinforcing mass-produced food consumption and dietary diversity loss as islanders, both at home and in the diaspora, transition to an industrialized diet. The loss of local labor similarly poses threats to agrobiodiversity, with export-oriented agribusiness simplifying landscapes to streamline extraction. This study demonstrates that to reclaim food systems in Guam, Puerto Rico, and similar island settings, laborers must be valued as stewards of cultural and agrobiodiversity and can be integral to efforts that preserve cultures, agroecosystems, and health.
