Your move

Decision guide

Choose Prawn

  • You want a lean, low-calorie protein source
  • You need a light meal that will not weigh you down
  • You are focusing on heart health and lowering saturated fat

Choose Beef Sirloin

  • You need long-lasting satiety and energy
  • You are trying to build muscle or recover from heavy training
  • You need a boost in iron or B12

Either works if

  • You simply need a high-quality, zero-carb protein source

Avoid both if

  • You have severe gout as both are moderate in purines
  • You are on a strict plant-based diet

Practical

Consumer tips

  1. 1

    Buy wild-caught Prawn when possible to avoid antibiotic exposure common in some farmed shrimp.

  2. 2

    Trim visible fat from Beef Sirloin before cooking to significantly reduce saturated fat content.

  3. 3

    Marinate Beef Sirloin with herbs and spices to reduce potential carcinogens from high-heat grilling.

  4. 4

    Cook Prawn quickly as overcooking makes them rubbery and reduces their enjoyable light texture.
