Why Protein Matters in Your Diet

Protein is vital for your body's everyday functions, supporting muscle growth, tissue repair, and immune health. Including high-protein kinds of seafood like fish, sushi-grade salmon, and shellfish in your diet helps:

• Boost satiety: Protein-rich meals keep you full longer, reducing the likelihood of overeating.
• Build and maintain muscle: Adequate protein intake is crucial for muscle growth, especially when a healthy diet combines strength training.
• Support metabolism: Eating protein can increase your metabolic rate slightly as your body works to digest it. This has the potential to aid weight management.
• Strengthen bones: Protein intake reduces osteoporosis risk and improves bone density.
