Abstract:
Malnutrition remains a persistent issue in Sudan, affecting millions of people, primarily children under five years old. The Integrated Food Security Phase Classification (IPC) alert for Sudan highlights the urgent need for multi-sectoral humanitarian assistance to save lives, prevent worsening acute malnutrition, and avert potential deaths, particularly among children. Many Sudanese children are already malnourished due to being weaned on cereal-based traditional meals. These diets are thick, highly viscous, and low in nutrient density for young children. Therefore, an immediate evaluation (e.g., of traditional complementary foods) and action (e.g., improving nutritional practices among healthcare providers and increasing public awareness) are necessary to address the high levels of acute malnutrition and prevent loss of life. This short communication outlines a practical method to produce ARP and its incorporation into common cereal-based foods; this approach may help reduce viscosity and increase energy density in complementary feeding. This study presents a compelling case for using amylasetreated cereal-based foods to fight malnutrition in Sudan. It combines scientific insight with practical application, making it an invaluable resource for both researchers and policymakers. Future research into the implementation challenges and long-term effects of ARF consumption is recommended.
