<![CDATA[Stunting remains a major public health problem in Indonesia, with prevalence rates still above national targets. The complementary feeding period (6–24 months) is a critical window for prevention, during which inadequate protein intake significantly contributes to impaired linear growth. Local animal protein sources offer an accessible and sustainable strategy to improve dietary quality. This study aims to review scientific evidence on the role of local animal protein sources in nutritionally balanced complementary feeding for the prevention of stunting in Indonesian infants aged 6–24 months. A literature review was conducted by systematically searching scientific databases for studies published between 2020 and 2025. Inclusion criteria were studies conducted in Indonesia, focusing on children aged 6–24 months, and examining the relationship between protein intake, complementary feeding, and stunting. A total of 22 eligible articles were analyzed using a narrative synthesis approach. The findings indicate a strong and consistent association between protein intake and stunting. Low intake of animal protein increases the risk of stunting (Odds Ratio 3–7). Local protein sources such as fish, eggs, and poultry provide high-quality protein and essential nutrients, including iron, zinc, vitamin B12, and omega-3 fatty acids, which support growth. Interventions promoting local protein-based complementary feeding have been shown to improve nutritional status. However, factors such as maternal knowledge, sanitation, and feeding practices influence the effectiveness of these interventions. Local animal protein sources play a vital role in complementary feeding for stunting prevention. Integrating their use with nutrition education and improved sanitation is essential to accelerate stunting reduction in Indonesia.]]>
