Crab meat offers a substantial amount of protein, a vital nutrient for building and repairing tissues, supporting immune function, and producing enzymes and hormones. A 3-ounce serving of cooked crab generally provides approximately 20 grams of this macronutrient, making it a valuable component of a balanced diet. This amount can vary slightly depending on the species of crab.
Adequate protein intake is essential for maintaining muscle mass, particularly during weight loss or aging. It also contributes to feelings of fullness, which can aid in appetite regulation. Historically, seafood, including crab, has played a crucial role in providing coastal communities with a readily available source of dietary protein. This nutritional powerhouse also provides essential minerals like selenium and zinc, further contributing to overall health.
