This article addresses the importance of developing resilient food systems in response to potential Abrupt Sunlight Reduction Scenarios (ASRS). It initially focuses on identifying vitamin D-rich foods that can be produced, stored, and distributed during global food crises. Through the use of weighting matrices, various factors were evaluated, such as availability, vitamin D concentration, bioavailability, overall nutritional value, and production scalability. The results identify anchovies, chicken eggs, and cod liver oil as the most viable options to ensure adequate vitamin D intake. In particular, eggs and cod liver oil are effective during the first 3 to 9 months of the crisis, while anchovies are viable both during this initial period and the second phase, which lasts from 4 to 18 months. The study also analyzes the limitations and potential challenges in producing and distributing these foods under extreme conditions, highlighting the need for future research to propose strategies aimed at ensuring food security in crisis situations.
