High-Quality Protein Source: Freshwater prawns are a rich source of high-quality protein, which is essential for building and repairing tissues, supporting immune function, and maintaining overall health.
Low in Calories and Fat: Prawns are relatively low in calories and fat, particularly saturated fat. This makes them suitable for individuals looking to manage their weight or reduce saturated fat intake.
Rich in Essential Nutrients: Prawns provide essential nutrients such as vitamin B12, phosphorus, selenium, and zinc. These nutrients play roles in various bodily functions, including nerve function, bone health, immune system support, and antioxidant defense.
Heart Health: Prawns contain omega-3 fatty acids, which can contribute to heart health by reducing inflammation, improving blood vessel function, and potentially lowering the risk of cardiovascular disease.
Brain Health: Prawns contain omega-3 fatty acids, particularly docosahexaenoic acid (DHA), which is a key component of brain cell membranes and is important for brain health and cognitive function.
Blood Sugar Regulation: Prawns’ protein content can help stabilize blood sugar levels and promote satiety, which may be beneficial for individuals with diabetes or those trying to manage their blood sugar.
Low in Carbohydrates: Prawns are naturally low in carbohydrates and sugars, making them suitable for low-carb or ketogenic diets.
Prawns are a source of Antioxidants. They contain antioxidants such as selenium, which can help protect cells from oxidative stress and contribute to overall health.
Iron Content: While not a significant iron source, prawns provide some essential mineral, vital for carrying oxygen in the blood and preventing iron deficiency anemia.
Collagen Formation: Prawns contain a moderate amount of zinc, vital for collagen formation, wound healing, and maintaining healthy skin.

While freshwater prawns offer these potential health benefits, a balanced and varied diet that includes a wide range of nutrient-rich foods is key to overall health and well-being.
