Prawns are good source of protein, including a good amount of healthy omega-3 fatty acids, while also being relatively low in calories. Three ounces (85 grams) of prawns contain approximately 18 grams of protein and only about 85 calories. In addition to providing lean protein and healthy fats, these crustaceans are very good sources of selenium, an important antioxidant.
You can get nearly 50% of the daily value of selenium in only 3 ounces (85 grams). Lastly, prawns and shrimp are very good sources of vitamin B12, iron, and phosphorus.
