White meat can include birds (chicken, duck, goose, turkey, etc. ), fish, reptiles, amphibians, crustaceans (shrimp, crabs, etc. ) or bivalves (oysters, clams), etc. Salmon and cooked shrimps and crabs are both red, but they can't be regarded as red meat. The color of cooked food cannot be used as a criterion to judge whether it is red meat or white meat. For example, although pork turns white during cooking, it is still red meat.
The difference between red meat and white meat
First, color.
The biggest difference is color, which is also the most intuitive performance. The reason why red meat is red is mainly caused by different components. Red meat contains more iron, so it appears red, while white meat contains less, so the color shows the color of the meat itself.
Second, the nutritional structure
Both red meat and white meat contain protein, but the contents of other nutrients are quite different. The main difference lies in the type of fat. Red meat is rich in saturated fatty acids, which is not good for health. On the contrary, white meat contains less saturated fatty acids, and most of the oil is unsaturated fatty acids.
