Prof. Aron Troen

 

Prof. Aron Troen is a member of The Hebrew University of Jerusalem, where he directs the Nutrition and Brain Health Laboratory and teaches in the School of Nutrition Science and the School of Public Health. Much of his research is concerned with clarifying the basic biological connection between dietary quality and brain health. However, for many people, putting nutritional insight into practice is not simply a matter of life-style choices, but a matter of life-circumstances. Prevalent food insecurity is a key driver of ill health, deprivation and economic harm worldwide, including in High Income Countries like Israel. Evidence-based policy is essential to improve the food security, welfare, health and resilience of individuals and nations, to enhance the quality of the food supply, and to ensure that it is equitable, safe and sustainable. Therefore, in addition to his core translational research, Troen’s evolving research and public service activities examine Israeli food policy reform and anti-obesity legislation, micronutrient fortification and food security, including during the COVID pandemic. He is particularly interested in how Israeli policies affect disparities in diet and health that correspond to socioeconomic and ethnic differences in food insecurity. He serves on several government committees on nutrition, health and food security, and on the Myers-JDC-Brookdale Institute steering committee for evaluating the Israeli government’s front of package food labeling policy, and he recently led a Food Security round table in the State of Israel Food System Dialogues in preparation for the UN World Food Summit.

Troen received his doctorate from Oxford University and BSc from the Hebrew University of Jerusalem. Prior to returning home to join the Hebrew University, he was on faculty at the Freidman School of Nutrition Science and Policy, and the Jean Mayer United Stated Department of Agriculture Human Nutrition Research Center on Aging at Tufts University.

Abstract

Background: The ongoing Hamas-Israel war puts the civilian population in Gaza at risk of severe food and nutrition insecurity. Our goal was to provide objective, verifiable data to ascertain amounts and nutritional content of food donations entering Gaza through Israeli border crossings from January to July 2024. We aimed to assessed their compliance with Sphere international humanitarian standards for food security and nutrition maintenance in crisis affected populations.

 

Methods: We obtained the registry of all food aid delivered to Gaza via air drops and land crossings for the study period from Israel’s Coordinator of Government Activities in the Territories (COGAT).  This registry itemizes daily food shipments, items and estimated weights. It provides more complete data than the UN dashboards because it includes food supplied by state, private, and commercial sector donors, who are not affiliated with the UN aid clusters. Each food item in each shipment was categorized, quantified, and assessed for its nutrient composition. We then summed the energy, protein, fat, and iron content of all shipments, and calculated supply per capita per day, according to the size of Gaza’s population. Finally, we compared it to the Sphere standards for food security and nutrition.

 

Results: After accounting for food loss, a net total of 478,229 metric tons of food was delivered to Gaza. The average amount of energy available per person per day was 3,004 kcal, with 98 grams of protein (13.0% of energy), 61 grams of fat (18% of energy), and 23 milligrams of iron. Except for February there was a steady increase in the caloric, macronutrients and iron donated into Gaza that was registered by COGAT.  The amounts of energy, protein, and fat exceed Sphere standards and remain consistent even after making adjustments for high food loss and the age distribution of the Gazan population.

Conclusions: This study assessed humanitarian food aid deliveries and availability in the Gaza Strip, the first pillar for meeting nutritional needs of the Gazan population. We found that with the exception of February, food aid delivered to Gaza during January-July 2024 exceeded the minimal daily per capita needs of all the people in Gaza, meeting humanitarian standards. While availability, the first pillar of food security, appears to be adequate, ensuring the food security of the population requires evaluation of the three remaining pillars of food security: access, utilization, and stability. With increased cooperation, the UN Food Security Cluster and COGAT could develop a comprehensive and continuously updated database of available food in Gaza. This would not only improve the transparent and objective assessment of food insecurity, but also ensure that future donations and their distribution could be tailored to meet the population's dynamic needs and circumstances.

Basic Research

Nutrition and Brain Health Laboratory

Preventing the decline in cognitive function that attends normal and pathologic brain aging is one of the greatest challenges of our time. The current trends of population growth and aging predict dramatic increases in the burden of dementia, cerebrovascular disease and stroke, while therapies for prevention and treatment of these conditions remain limited. Understanding the role of nutrition in brain aging and cognitive decline is of major fundamental, clinical and public health importance because nutritional interventions may offer safe and effective measures for brain protection, and for the insight it can provide into the fundamental mechanisms of brain aging.

The long-term goal of our research program is to establish nutritional and pharmacologic interventions to prevent age-related cognitive impairment. A primary focus is to understand how dietary and genetic modulation of one-carbon metabolism regulates microvascular and neuronal plasticity in the adult and aging brain. We use dietary interventions in rodents to model clinically relevant associations between nutrition and brain-aging in humans (for example, by modifying dietary folate intake). The mechanistic basis for these associations can then be delineated by identifying the integrated effects of diet on in vivo brain metabolism, cellular regulation, cerebrovascular and neuroanatomy, physiology, and ultimately behavior. Integrating these outcomes we aim to: 1) define the role of microvascular plasticity and neuronal-centric processes for maintaining cognitive function; 2) identify diet-responsive microvascular and neuronal signaling pathways; 3) establish new, clinically relevant and urgently needed animal models of vascular cognitive impairment; 4) establish novel, standardized, objective and quantitative anatomical and functional measures of microvascular health for basic and pre-clinical research; thereby laying the foundation for new ways of preventing and treating age-related cognitive impairment

This in vivo work is both informed by and informs ongoing collaborative research projects on epidemiological studies and clinical trials deigned to determine the role of nutritional status, gene-nutrient interactions and nutrition based-interventions on cognitive health in older adults.

In support of these aims we are leading a collaboration with the Fantini laboratory in the Dept. of Biomedical Engineering at Tufts University on developing and applying a non-invasive, quantitative near infra-red spectroscopy instrument for fundamental and pre-clinical research in animal models, and for translational application to human studies.
