Despite common marketing, why is pork scientifically classified as red meat?

Answer

Due to its myoglobin levels matching those found in mammalian muscle tissue.

Pork is scientifically classified as red meat because its muscle tissue contains myoglobin levels comparable to other mammalian sources like beef or lamb. The color distinction in meat is directly attributed to the concentration of myoglobin, the oxygen-transporting protein found in muscle cells. While marketing sometimes refers to pork as 'the other white meat,' this culinary designation does not align with the scientific measurement of myoglobin content, which firmly places pork within the red meat category characterized by a typically redder hue when uncooked or rarely cooked due to this higher protein presence.
