Dietitian's Tips for Consuming Crustaceans

  • Metabolic Impact: Crustaceans provide complete protein with high bioavailability, strongly supporting muscle synthesis and noticeably prolonging satiety. Trace elements such as zinc and selenium found in crustaceans also positively influence thyroid hormone balance and immune function.
  • Consumption Recommendation: Consuming crustaceans 2-3 times per week is sufficient to meet your omega-3 and high-quality protein needs. Cooking methods such as boiling or grilling help preserve nutritional value while keeping the calorie load low.
  • Caution: Crustaceans are among the most common triggers of allergic reactions, so first-time consumers are advised to start with small amounts. Additionally, due to their relatively high sodium content, individuals managing blood pressure should pay close attention to portion sizes.
  • Exercise: Consuming crustaceans after training supports muscle repair and speeds up recovery thanks to their rapidly absorbed amino acid profile. Low-fat varieties such as shrimp or lobster in particular make it easier for athletes to reach their daily protein targets.
