Langostino, also called langostine and langoustine, is commonly thought of as lobster, although it is not. Rather, it is a pelagic crab. This small shellfish resembles a lobster in taste, texture and appearance, but costs less than authentic lobster. Restaurants across the United States often offer langostino on their menus; not all identify it as such, however. Many call it lobster, which has created some controversy in some industries including the fishing industry.

Langostino contains no carbohydrates, although it does provide you with 21 grams of protein per serving.

You may also need to monitor your diet plan for cholesterol – a serving of langostino has 100 mg. A heart-healthy diet should not include more than 300 mg of cholesterol each day.
