The meat of mammals is called red meat, such as beef, pork and mutton. Chicken, duck, goose, fish, shrimp and crab are called white meat.

White meat is better for human body than red meat, but it should not be eaten more, because meat is acidic food, which increases the acidity of body fluids. It is best to eat more green leafy vegetables to neutralize acidity, because the body fluids of healthy people are weakly alkaline at pH 7.35 ... 7.45.
