How much protein in crab?


Crab is a popular seafood delicacy enjoyed by many around the world. It is not only delicious but also known for its nutritional value. One important aspect of its nutritional profile is its protein content. In this article, we will explore the amount of protein found in crab and its significance in a balanced diet.

Protein Content in Crab

Crab is a rich source of protein, which is an essential macronutrient required by the human body for various functions. The amount of protein in crab can vary depending on the species and the specific part of the crab consumed. Generally, the meat of a crab contains a significant amount of protein.

On average, a 100-gram serving of crab meat provides approximately 20 grams of protein. This makes it an excellent choice for individuals looking to increase their protein intake. The protein content in crab is comparable to other popular seafood options like shrimp and lobster.

Benefits of Protein

Protein plays a crucial role in maintaining and repairing body tissues, supporting the growth and development of muscles, and aiding in the production of enzymes and hormones. Including an adequate amount of protein in your diet is essential for overall health and well-being.

Consuming protein-rich foods like crab can help promote satiety, making you feel fuller for longer periods. This can be beneficial for individuals trying to manage their weight or those following a calorie-controlled diet. Additionally, protein is known to have a higher thermic effect compared to carbohydrates and fats, meaning it requires more energy to be digested and metabolized by the body.

Protein is also important for maintaining a healthy immune system. It helps in the production of antibodies and supports the body’s defense against infections and diseases. Furthermore, protein is involved in the transportation of nutrients, oxygen, and waste products throughout the body.

Other Nutritional Benefits of Crab

In addition to protein, crab offers several other nutritional benefits. It is a good source of vitamins and minerals, including vitamin B12, selenium, and omega-3 fatty acids. Vitamin B12 is essential for the formation of red blood cells and the proper functioning of the nervous system. Selenium is an antioxidant that helps protect cells from damage, and omega-3 fatty acids are beneficial for heart health.

Crab meat is also relatively low in calories and fat, making it a healthier choice compared to other protein sources like red meat. It contains minimal saturated fat and cholesterol, which are known to contribute to heart disease when consumed in excess.


Crab is a delicious seafood option that offers a significant amount of protein, along with other essential nutrients. Including crab in your diet can help meet your protein needs and provide various health benefits. Whether you enjoy it in a crab cake, as a topping for a salad, or in a seafood boil, crab can be a nutritious addition to a balanced diet.
