Scientists therefore relied on modern biotechnology to introduce 2 transgenes that enabled carotenoid production and accumulation, with 80%-90% as β-carotene. The second generation of Golden Rice, incorporating genes from maize and a common soil bacterium, can produce 20-30 μg of β-carotene per gram of edible rice. Although carotenoid levels decline in storage, they remain high enough to contribute meaningfully to vitamin A intake. After its initial development, Golden Rice technology was transferred to public sector breeding programs in low- and middle-income countries, prioritizing Bangladesh and the Philippines due to prevalent vitamin A deficiency, high per capita rice consumption, strong agricultural research institutes, and prior experience with transgenic crops. Both countries have developed locally adapted Golden Rice varieties matching conventional rice in agronomic performance, cultivation practices, and cost. However, regulatory hurdles have stalled their release-approval remains pending in Bangladesh, whereas legal challenges in the Philippines have at least temporarily halted further research and deployment.

Yet, unlike food security, which has well-established measures, nutrition security lacks standardized measures for assessment. This gap hinders the ability to evaluate progress in improving nutrition security both in the United States and globally. In September 2024, a workshop to explore how to measure nutrition security was hosted by the United States Department of Agriculture Economic Research Service, in collaboration with the Southern University Agricultural Science Center of Excellence for Nutrition and Diet Nutrition Hub. A recent conceptual framework proposes that nutrition security includes the 2 constructs of healthy diets and nutritional status, but consensus on that framework and on measurement is lacking. Various measures of nutrition security have been proposed, each with different methods, feasibility, cost, and data requirements. With consensus yet to emerge on the conceptualization and measurement of nutrition security, further research is needed to validate proposed conceptual frameworks, refine measurement methods and measures, assess their validity, and determine their utility for monitoring nutrition security at the population level.
