Core Tip: Meat is an indispensable food in our lives, and most parts of an animal can be consumed. However, there are some parts you should never eat, as they can easily lead to health problems.
1. The "black membrane" of fish should not be eaten:
There is a layer of black membrane on both sides of the fish's abdominal cavity. It is the most fishy and earthy part and contains a large amount of lipids, lysozyme, and other substances.
2. The "sharp tip" of poultry should not be eaten:
This is the part at the top of the chicken, duck, or goose where the tail feathers grow. Its scientific name is "bursa of Fabricius," a place where lymphoid glands are concentrated. Because the macrophages in the lymphoid glands can engulf bacteria and viruses, including carcinogens, but cannot break them down, the "sharp tip" of poultry acts as a "repository" for filth.
3. The meat nodules on a pig's neck should not be eaten:
When preparing, one should easily remove the gray, yellow, or dark-red meat nodules from the pig's neck and other areas, also known as "meat jujubes." These areas contain many bacteria and viruses, and consuming them can easily lead to infection.
4. Chicken heads should not be eaten:
There is a Chinese proverb: "A ten-year-old chicken head is more potent than arsenic." Why does the toxicity of a chicken head increase with its age? Medical experts analyze that the reason is that chickens ingest harmful heavy metals while pecking for food.
5. Chicken necks should not be eaten:
Do not eat the skin of chicken or duck necks, and do not eat the trachea. These areas contain a large amount of high cholesterol, so it is best to avoid eating these parts.
6. The "three glands" of livestock should not be eaten:
The thyroid, adrenal glands, and diseased lymph glands in pigs, cattle, sheep, and other animals are three types of "physiologically harmful organs."
7. Sheep "suspensory ligament":
Sheep "suspensory ligament" (also known as "hoof white pearl") is generally round or串珠状 (string-of-beads-shaped) and is a tissue that has undergone pathological changes within the sheep's hoof.
8. Rabbit "scent glands" should not be eaten:
The white inguinal glands located under the skin on both sides of the external genitalia, the brown inguinal glands adjacent to them, and the anal glands located on both sides of the rectal wall have an extremely strong and foul odor. If not removed before cooking, they will make the rabbit meat inedible.
