The nutritional value of staple crops, fruits, and vegetables is fundamental to public health, particularly when consumed in their natural, unprocessed form. Enhancing the quality of crops requires approaches that not only improve yields but also increase nutrient density, bioavailability, and overall food quality. Equally important is the ability to measure these improvements: monitoring nutrient content from soil to harvest provides a clearer picture of how agricultural practices influence human nutrition. Reliable, low-cost, and rapid testing methods would allow farmers and food systems to better understand the impact of inputs and practices on crop quality and to ensure more consistent delivery of nutritious food. 

By enabling both the improvement and transparent measurement of crop nutrition, innovative approaches can make more nutritious food available, support stronger market differentiation for producers, and contribute to better human health outcomes.
