Crab Meat Protein: A Powerhouse

High-Quality Protein Source
Crab meat is truly high in protein, making it an excellent choice for your diet. You get about 23.5 grams of protein for every 100-gram serving. This makes crab meat a fantastic way to meet your daily protein needs.
What makes a protein source “high-quality”? A high-quality protein provides all nine essential amino acids your body needs. It also digests and absorbs easily. Crab meat meets these important standards. It gives you the right amount of nitrogen and all the necessary amino acids to keep your body working well. This includes building and repairing tissues.
While chicken breast has about 30% more protein than crab meat per 100 grams, crab meat remains a good source of protein. It is also a high-quality lean protein option. It is low in fat and calories, which helps you maintain a healthy weight.
Food Item | Protein per 100g |
|---|---|
Chicken | 23.3g |
Crab Meat | 17.9g |
Essential Amino Acids Profile
Your body needs essential amino acids, but it cannot make them on its own. You must get them from your food. Crab meat is a complete protein source. This means it contains all nine essential amino acids. These are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
For example, in Sudanonaonautes aubryi crab meat, valine and histidine are very common essential amino acids. Other important ones include leucine and lysine.
Here is a closer look at the essential amino acids you find in crab meat:
Amino Acid | mg/g of protein |
|---|---|
Valine | 45 |
Leucine | 73 |
Isoleucine | 43 |
Histidine | 22 |
Lysine | 77 |
Threonine | 40 |
Tryptophan | 13 |
Met+Cys | 36 |
Phe+Tyr | 76 |

You can see that L-Arginine and Leucine are especially abundant in lump crab meat. In crab roe, Leucine, Valine, and Histidine are particularly plentiful.
Amino Acid | Lump Meat (%) | Roe (%) |
|---|---|---|
L-Arginine | 10.07 | 7.71 |
Leucine | 9.69 | 11.04 |
Histidine | 3.60 | 5.38 |
Valine | 4.49 | 6.20 |
Isoleucine | 4.11 | 4.51 |
Lysine | 8.37 | 6.02 |
Methionine | 4.33 | 4.39 |
Phenylalanine | 4.49 | 4.92 |
Threonine | 3.68 | 4.84 |
Tryptophan | 0.74 | 1.45 |

Protein’s Role in Muscle and Satiety
The protein in crab meat does more than just build muscle. It also helps your body repair itself and supports your immune system. When you exercise, your muscle fibers get tiny tears. The essential amino acids from crab meat help your body create new muscle proteins. This repairs and strengthens your muscles. This process is vital for muscle growth and recovery after physical activity.
Crab meat is also high in protein, which helps you feel full and satisfied. This feeling of fullness is called satiety. Seafood, like crab, often ranks very high for satiety. It provides many nutrients with fewer calories. This means you can satisfy your hunger and cravings more efficiently. Crab has a satiety score of 80%.
Consider the difference between real crab and imitation crab meat:
Seafood Type | Satiety Score | Protein per 100g (3.5 oz) |
|---|---|---|
Crab | 80 | Approximately 20 grams |
Imitation Crab Meat (Surimi) | 61 | Approximately 8 grams |
Imitation crab meat has less protein and fewer nutrients. This means it does not make you feel as full. Choosing real crab meat gives you a better nutritional profile and helps you stay satisfied longer.

Omega-3s: Heart and Brain Health
Omega-3 Content in Crab
Crab meat offers valuable omega-3 fatty acids. These are important for your health. Specifically, you find EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in crab meat. For example, a 100-gram serving of canned blue crab or Alaskan King crab gives you about 0.4 grams of these omega-3s, measured as ‘EPA plus DHA’. This means you get beneficial fats when you eat crab meat.
Crab vs. Other Seafood Omega-3s
While some fatty fish like salmon have higher levels of omega-3 fatty acids, crab meat still provides important marine omega-3s. You add these healthy fats to your diet when you choose crab. It is a good way to get these essential nutrients. Even if it is not the highest source, crab meat remains rich in omega-3 fatty acids. You benefit from these marine omega-3s.
Cardiovascular and Cognitive Benefits
The omega-3 fatty acids in crab meat support your heart and brain. These high levels of omega-3 fatty acids help your cardiovascular system. Studies show that omega-3s from seafood can lower your risk for heart attack. They also reduce death from coronary heart disease. The FDA even approved a specific omega-3 medicine to reduce heart event risks. A scientific review highlights that long-chain n-3 polyunsaturated fatty acids (PUFA) from seafood significantly reduce cardiac death risk. These omega-3s lower plasma triglycerides, resting heart rate, and blood pressure.
Beyond your heart, omega-3 fatty acids boost your brain function. They improve mental performance and cognitive processes. You experience better blood circulation in your brain. DHA intake can improve early memory and learning. Omega-3 PUFAs are essential for proper brain growth. They also help protect brain cells and lower inflammation. EPA supplementation is linked to higher cognitive performance. DHA can act as a neuroprotective agent for some early memory problems.
