Pig serum lung, does it really work? What is the truth?

In fact, there are many little folk common sense circulating in life, some of which are true and some are false. It depends on how you distinguish them. So is it true that pig blood can clear the lungs? Let’s take a look together!

Eating pig blood and duck blood can clear the lungs and remove dust

According to folk legend, eating animal blood can moisten the lungs and remove dust. People who work in professions that frequently come into contact with dust, such as teachers, coal miners, and cleaners, should eat more blood, which will be of great benefit.

The truth: Eating animal blood will not clear the lungs and remove dust, because the dust inhaled by the human body goes directly into the lungs, while the animal blood eaten stays in the large intestine. The digestive tract and respiratory tract are not connected, so the dust in the lungs cannot be removed. The folk legend of "eating blood to remove dust" is actually that the unabsorbed heme iron in animal blood combines with sulfide under the action of gastric acid and intestinal bacteria to form black iron sulfide, which dyes the feces black, thus giving people the illusion that it can remove dust.

Eating eggs and potatoes together will cause poisoning. Eggs and potatoes cannot be eaten together, otherwise it will cause vomiting or even poisoning!

The truth: Eating potatoes and eggs together will not cause poisoning, but it will affect absorption. Potatoes contain trypsin inhibitors, which can inhibit the activity of human proteases and affect the digestion and absorption of protein in the human body. Egg whites contain sticky proteins that can combine with the trypsin in potatoes, hindering the decomposition of protein and thus reducing the body's absorption rate of protein.

Apples and yogurt cannot be eaten together. Apples contain acid, and yogurt contains calcium. If they are eaten together, a chemical reaction will occur and the mixture will turn into precipitation, which will not be absorbed by the human body. It's like eating it for nothing.

The truth: Apples and yogurt can be eaten together. Yogurt contains trace elements such as calcium and zinc, while apples are rich in vitamins C and D, which are beneficial to the absorption of trace elements. However, it should be noted that both apples and yogurt are acidic foods and should not be eaten frequently, otherwise it may cause excessive stomach acid.

White radish and carrots can be eaten together. Diet experts say that white radish and carrots are both extremely nutritious. Cooking them together not only saves time but also tastes delicious and nutritious.

The truth: It is best not to eat white radish and carrots together, because white radish is very high in vitamin C, but carrots contain an enzyme called ascorbic acid, which will destroy the vitamin C in white radish. Once red and white radishes are combined, the vitamin C in the white radish will be completely lost. Not only that, when cooked with vegetables containing vitamin C, carrots act as destroyers. Cucumbers, pumpkins, etc. also contain decomposition enzymes similar to those of carrots.

Eggs and sweet potatoes cannot be eaten together

Eggs and sweet potatoes are incompatible. Eating them together can cause stomach pain.

The truth: Eggs and sweet potatoes can be eaten at the same time. Sweet potatoes are rich in starch, vitamins, cellulose and other essential nutrients for the human body, while eggs contain protein and eight essential amino acids for the human body. They can be eaten together, but since both foods are not easy to digest, you must pay attention to the amount consumed. People with indigestion should not eat them at the same time.

Eggs with spots are non-toxic and can be eaten. The spots on eggs only grow on the outside of the eggshell and do not affect the egg white and yolk inside, so they can be eaten with confidence.

The truth: It is best not to eat eggs with spots. There are usually three situations in which eggs develop spots. One is that the quality of the eggs has declined, or they have been stored for a long time, causing bacteria to adhere to the surface of the eggshell; the other is that the hen's fallopian tubes are inflamed. Inflammation of the hens' fallopian tubes is sometimes caused by infection with E. coli or Salmonella. Thirdly, the hens lack vitamins or methionine, and their immunity may be defective, which leads to spots on the eggshells.
