Chicken head and neck should not be consumed, and the thyroid, adrenal, and diseased lymph glands of pigs, cows, and sheep should also be avoided
Chicken tip lymphocytes densely distributed, eating less is better
Chicken tip, commonly known as chicken butt, has high-quality protein and a small amount of fat. Some diners believe that the chicken in this area has a smooth and unique taste. However, researcher Xi Zhenglin from the Nanjing Institute of Animal Husbandry and Poultry Science suggests not eating chicken tip. The part of the long tail feathers on the buttocks of poultry such as chickens, ducks, geese, etc., also known as the 'lumen sac', is a place where antibodies are formed. It is a central lymphatic organ with dense lymphocytes, so it is better to eat less in daily life, "said Associate Professor Huang Cheng from the School of Life Sciences at Nanjing University.
Chicken head and neck are not suitable for consumption
There is a folk saying in our country: ten years' chicken's head is better than arsenic. It is said that the older the chicken, the greater the toxicity of its head, as it will ingest harmful heavy metals during pecking. These heavy metals are mainly stored in brain tissue, and the longer the time, the more they are stored, and the stronger their toxicity. Is this terrifying rumor true?
Xi Zhenglin pointed out that although this statement has been circulating for a long time, no one has actually conducted tests, and no one can answer whether there is a toxin or how much it contains.
Associate Professor Huang Cheng from the School of Life Sciences at Nanjing University told reporters, "The chicken head is toxic. There is actually some basis for this claim, because there are lymph nodes near the chicken head to the neck, which are the immune and detoxification systems. Once the body is infected with bacteria and viruses, it can lead to lymphatic inflammation, and some bad metabolites are stored in the lymph nodes
It's best not to eat the "tendon stumbling" part of pork
The meat that Chinese people usually eat the most is pork, but when eating pork, they also pay attention to it. For example, when eating pork, gray, yellow, or dark red flesh bumps on the neck of the pig should be removed, which are called meat dates, because these places contain many bacteria and viruses, and if consumed, they are prone to infection. In addition, the thyroid, adrenal, and diseased lymph glands of pigs, cows, and sheep are three "physiological harmful organs" that should also be avoided from consumption.
Meat bumps are best not to eat
So, besides the pig neck, what other parts may have these flesh lumps? There are lymph nodes in the groin, some fat in the abdomen, and the mesentery, as well as many lymph nodes in pork flower oil. It is important to pay attention to them in daily life
So what is the reason why the "three glands" cannot be eaten? The thyroid gland of pigs, cows, and sheep is located in the neck of animals; the adrenal gland is an endocrine organ, located around the kidneys, because the kidneys are detoxifying organs, and the adrenal gland should not be eaten; diseased lymph glands may be distributed in multiple parts of the body, but there is no need to worry, most of these have already been disposed of before entering the market
The "black coat" of fish is not harmful
It is pointed out that there is a layer of black film coating on both sides of the abdominal cavity of the fish, which is the most smelly and earthy part. It is said that the membrane structure metabolism is slow, toxins are easy to deposit on it, and there are a lot of lipid like, lysozyme and other substances, so you must not eat them.
What exactly is this layer of 'black clothes'? Huang Cheng told reporters that this is actually the abdominal membrane of a fish, which is a type of connective tissue. Currently, no harm has been identified.
Experts from the Jiangsu Provincial Institute of Freshwater Fisheries also believe that this layer of black clothing is actually just a protective film for the fish itself, and the taste is indeed quite fishy. "Usually, when dealing with it at home, this layer of black clothing is removed, but it cannot be said to be harmful, it is just a matter of habit
