We can't live without meat, chicken wings, mutton, pig neck and so on almost every day. They are all delicious foods that people often eat, but do you know which parts can't be eaten? The following parts will endanger your health, so pay attention.

1, fish "black" cannot be eaten:

There is a black coating on both sides of the abdominal cavity of fish, which is the most fishy and earthy part, and contains a lot of lipid-like, lysozyme and other substances.

2, birds "pointed wings" can't eat:

Birds such as chickens, ducks and geese all have long tail feathers at the top of their butts. The scientific name "bursa on the cavity" is the place where lymph glands are concentrated. Because macrophages in lymph glands can devour germs and viruses, even carcinogens can be swallowed, but they cannot be decomposed, so the "sharp wings" of birds are a "warehouse" for hiding evil and tolerating evil.

3, pig neck meat bumps can not eat:

When eating, it should be easy to remove the gray, yellow or dark red pimples on the pig's neck, that is, the thing called meat jujube, because these places contain many germs and viruses, and it is easy to get sick after eating.

4, the head of a chicken can't eat:

There is a folk proverb in our country: the head of a chicken is better than arsenic in ten years. Why does the older the chicken, the more poisonous the head of the chicken? Medical experts believe that the reason is that chickens will eat harmful heavy metals when pecking.

5, chicken neck can not eat:

Don't eat the skin of chicken neck and duck neck, and don't eat trachea. It contains a lot of high cholesterol, so it is best not to eat these parts.

6, livestock "three glands" can't eat:

Thyroid gland, adrenal gland and pathological lymph gland are three kinds of "physiological harmful organs" in animals such as pigs, cattle and sheep.

7. Sheep "hanger bar":

The "hanging tendons" of sheep (also called "hoof white beads") are generally round and granular, which is a pathological tissue of sheep's hoof.

8, the rabbit's "smelly gland" can't eat:

The rat gizzard located under the skin on both sides of the back of the external genitalia, the brown rat gizzard next to the rat gizzard, and the rectal glands on both sides of the rectum have a very bad smell, which will make the rabbit meat difficult to swallow if it is not removed when eating.
