Bio

Erick Boy is the chief nutritionist in the HarvestPlus section of the Innovation Policy and Scaling Unit. As head of nutrition for the HarvestPlus Program since 2008, he has led research that has generated scientific evidence on biofortified staple crops as efficacious and effective interventions to help address iron, vitamin A, and zinc deficiency in sub-Saharan Africa, Latin America, and South Asia. Major contributions to the global nutrition community from the HarvestPlus research portfolio during his tenure include the first publications on the impact of biofortification as a dietary intervention to improve nutritional status and aspects of health causally associated with iron, vitamin A, and zinc. Currently, his main area of research is exploring the association between zinc and chronic noncommunicable diseases such as type 2 diabetes mellitus.

Prior to joining HarvestPlus, Erick worked for 10 years at the Institute of Nutrition of Central America and Panama (INCAP/PAHO), where his research focused on the prevention of low birth weight and the control of iodine and iron deficiencies. The demonstration of the impact of indoor biofuel smoke on birth weight was a memorable contribution during this phase of his career.

At the Micronutrient Initiative (1999-2008), Erick directed the iron and zinc research program, and managed Latin American projects and the Global Vitamin A Supplementation Procurement Project. He was instrumental in the introduction of zinc supplements for the treatment of diarrhea and multiple micronutrient powders to treat anemia in several Latin American countries. Erick holds a medical degree from the Universidad de San Carlos de Guatemala and a master’s and doctoral degree in human nutrition from the University of California at Davis.

An ex-ante analysis of the impact of biofortified zinc rice on dietary zinc inadequacy: Evidence from Bangladesh, Indonesia, and the Philippines

Background: South, East, and Southeast Asia are among the regions of the world with the highest estimated prevalence of inadequate zinc intake. Because populations in those regions eat rice as their main staple, zinc biofortification of rice can potentially improve zinc intake, especially among the most vulnerable. Objectives: We modeled the impact of the consumption of zinc-biofortified rice on zinc intake and inadequacy among women of childbearing age and young children nationally in Indonesia, the Philippines, and at a subnational level in Bangladesh. Methods: We conducted an ex-ante analysis by applying increments of zinc content in rice, from a baseline level of 16 parts per million (ppm) to 100 ppm, and based on rice consumption data to substitute levels of conventional rice with zinc-biofortified rice varying between 10% and 70%. Results: Among all datasets evaluated from these 3 countries, the prevalence of dietary zinc inadequacy at baseline was 94%–99% among women of childbearing age, 77%–100% among children 4–5 y old, and 27%–78% among children 1–3 y old. At the current breeding target of 28 ppm, zinc-biofortified rice has the potential to decrease zinc inadequacy by ≤50% among women and children in rural Bangladesh and among children in the Philippines where consumption of rice is higher compared with Indonesia. Conclusions: Our analysis shows that increasing zinc content in rice ≤45 ppm reduces the burden of zinc inadequacy substantially, after which we encourage programs to increase coverage to reach the highest number of beneficiaries.

Introduction and executive summary for the supplement micronutrients in Latin America: Current state and research

Introduction and executive summary for the supplement micronutrients in Latin America: Current state and research

Global health and nutrition stakeholders are facing a period full of changes and challenges, especially in low- and middle-income countries (LMIC). Almost every country is experiencing at least, one burden of malnutrition,1 and among them many are facing the triple burden of malnutrition, both associated with unhealthy and nondiverse diets and reduced physical activity. According to the State of Food Security and Nutrition in the World Report, in 2022, between 691 and 783 million people faced chronic hunger, representing an increase of 122 million people compared to 2019. It also informed that 3.1 billion people could not afford a healthy diet.2 On the one hand, economic shocks, war, violence, and climate-related disruptions are the leading causes of the current steep increase in the global burden of hunger in all its forms. The COVID-19 pandemic and other repeated pandemic shocks further reduce food and nutrition security of poor countries.3 On the other hand, chronic noncommunicable diseases, most of which are associated with overweight-obesity and unhealthy behavioral and environmental risk factors, continue to rise as the principal causes of death and disability worldwide, also disproportionately impacting LMIC.4 While the prevalence of hunger in Latin America and the Caribbean (LAC) is lower than the global average, food insecurity affects a higher proportion of the population in the region (40%) relative to the global prevalence (29.3%). The region also experiences the highest cost of a healthy diet, with 131 million people unable to afford to meet the recommended nutritional requirements that healthy diets would provide.5-7 Consequently, the risks of nutrient deficiency and excess for the region can be inferred, but the scarcity of current nationally representative data on micronutrient deficiencies is neither useful for program planning or evaluation nor conducive to narrowing the equity and justice gaps in the region.

Bioaccessibility and bioavailability of biofortified food and food products: Current evidence

Biofortification increases micronutrient content in staple crops through conventional breeding, agronomic methods, or genetic engineering. Bioaccessibility is a prerequisite for a nutrient to fulfill a biological function, e.g., to be bioavailable. The objective of this systematic review is to examine the bioavailability (and bioaccessibility as a proxy via in vitro and animal models) of the target micronutrients enriched in conventionally biofortified crops that have undergone post-harvest storage and/or processing, which has not been systematically reviewed previously, to our knowledge. We searched for articles indexed in MEDLINE, Agricola, AgEcon, and Center for Agriculture and Biosciences International databases, organizational websites, and hand-searched studies’ reference lists to identify 18 studies reporting on bioaccessibility and 58 studies on bioavailability. Conventionally bred biofortified crops overall had higher bioaccessibility and bioavailability than their conventional counterparts, which generally provide more absorbed micronutrient on a fixed ration basis. However, these estimates depended on exact cultivar, processing method, context (crop measured alone or as part of a composite meal), and experimental method used. Measuring bioaccessibility and bioavailability of target micronutrients in biofortified and conventional foods is critical to optimize nutrient availability and absorption, ultimately to improve programs targeting micronutrient deficiency.
