This paper reviews and compares four leading healthy diet metrics: GDQS, GDR score, MDD-W, and Nova UPF score, for their accuracy, ease of use, and global applicability in monitoring dietary quality. The findings highlight that the Minimum Dietary Diversity for Women (MDD-W) offers the strongest predictive accuracy for nutrient adequacy using a simple, scalable method, while also emphasizing the need for further research on metrics assessing moderation and cross-country comparability.

The Future of Philanthropy: Stepping up for the United Nations Sustainable Development Goals

Corporate Responsibility (CR) starts with the positive impact RELX has on society through our products and services.
The SAHARAPONICS project introduced a low-cost, water-efficient aquaponic system in Sahrawi refugee camps to improve food security and nutrition in arid conditions. Using locally sourced materials and solar power, the system produces fish and crops while reducing water use by up to 90%. Despite increasing daily workload, community feedback highlights benefits in food access, economic opportunities, and empowerment, demonstrating the project's potential for sustainable development in water-scarce, vulnerable communities. This project supports multiple UN SDGs, including clean water and sanitation (Goal 6), zero hunger (Goal 2), good health and well-being (Goal 3), poverty reduction (Goal 1), sustainable cities (Goal 11), and responsible consumption (Goal 12).
