  • You have no shellfish allergies and want a sustainable seafood choice

Either works if

  • You just need a high-quality, zero-carb protein source
  • You are bored with chicken and want something different

Avoid both if

  • You are on a tight budget, as both are premium proteins
  • You have gout, as both contain moderate purines

Practical

Consumer tips

  1. 1

    If buying canned crab, check the sodium content and rinse it lightly to reduce salt.

  2. 2

    Always cook frog legs to an internal temperature of 165°F (74°C) to kill any parasites.

  3. 3

    Sourcing matters: look for farmed frog legs to reduce environmental contaminant risk, and check the origin of your crab for heavy metal safety.

  4. 4

    If trying frog legs for the first time, expect a texture closer to chicken wings than fish.
