A balanced protein-rich diet is essential to support the optimal growth, health, and productivity of farmed aquatic species. Tryptophan, an essential amino acid, plays a crucial role in protein synthesis and serves as a precursor for neurotransmitters such as serotonin (5-hydroxytryptamine) and melatonin, which regulate reproduction, appetite, stress, and aggression in fish. The shift toward sustainable feed solutions emphasizes the need for tryptophan supplementation to address the deficiencies in alternative protein sources. Tryptophan supplementation promotes growth by enhancing protein synthesis, muscle development, and nutrient absorption while mitigating stress and inflammation through serotonin and melatonin synthesis. Its antioxidant properties help regulate oxidative stress, protect against environmental damage, and improve fish resilience. Tryptophan also modulates immune functions and reproductive processes, highlighting its multifaceted significance in aquaculture. Tryptophan interacts synergistically with other nutrients to enhance growth and immune responses. However, imbalanced tryptophan levels can impair growth, immune function, and productivity, thus requiring precise dietary formulations. The optimal tryptophan requirement varies among species and target functions.

The Global Diet Quality Score (GDQS) application was used to measure food intake on the previous day, with each food tagged to an eating occasion.

Over 90% of adults had levels of GDQS scores associated with moderate/high risk of nutrient inadequacy and diet-related NCDs, with the proportion at high risk in Bangladesh being 2-3× higher than that in other countries. One-third of adults skipped breakfast in Nepal, and snacking was twice as common in males (63%) vs females (33%) in Bangladesh.
