It's really "full of pigs". You can cook anywhere.

Red meatballs, white meatballs, south fried meatballs, Four Joy Meetballs, Sam Sun meatballs, preserved meatballs, fresh shrimp meatballs, preserved fish meatballs, fried meatballs, tofu meatballs, cherry meat, horse tooth meat, rice flour meat, yipin meat, chestnut meat, jar meat, braised pork, braised pork, braised pork with sesame sauce.

Then, the question is, which parts of the pig are inedible?

1. Is pork related to cancer?

It's true. The World Health Organization put forward in 20 15:

Red meat (including pork, beef and mutton) belongs to Class 2A carcinogen; If processed meat (ham sausage, bacon, etc. ) belongs to class 1 carcinogen with relatively definite risk.

This means that according to the existing research evidence, eating red meat may cause cancer to people. Please pay attention to the wording here. "Maybe ... risky" doesn't mean that carcinogenicity equals toxicity, and you will get cancer immediately after eating it.

After all, pork, beef and mutton is an important contributor to provide us with high-quality nutrition such as protein, iron and vitamin B 12, which is indispensable in a sense.

Eat one a day on average? This kind of pork is about 50 ~ 75 grams, which is similar to other kinds of meat.

Do you think it's not enough to be unhappy without meat? You can also eat more white meat such as chicken, duck and fish, or you can save up all the amount for a few days and enjoy it.

Second, the pig's large intestine has poop, which is very dirty?

There must be many friends who like the unique "fragrant" taste of pig large intestine. The famous old Beijing pot-stewed fire is made of pig intestines.

It tastes delicious, but you may forget one thing: the large intestine is a place where the residue (that is, poop) after digestion of food is discharged, so it is a place with a unique taste.

There may be more microorganisms here, and there may be parasites and pathogens ... Does it sound dirty?

In fact, as long as the cleaning is thorough, no dirty things can be seen on the surface, and the microorganisms can be completely killed by heating, you can safely eat.

Third, is there much heavy metal pollution in pig liver?

Like pigs, the liver is the biggest "detoxifier" and "transit station" of poisons. Toxic and harmful substances such as heavy metals enter the body and need to be treated by the liver before they can be discharged. If it is a sick pig, the liver can decline, or if you eat too many toxic and harmful substances by mistake, these harmful substances will accumulate in the pig liver.

The "relatively high" content of heavy metals in pig liver does not mean that it must exceed the standard. The key is to choose a reliable place as far as possible and buy products with inspection and quarantine marks.

Like pork, it is very helpful to supplement heme iron and hemoglobin by replacing other red meat with pig liver and eating 1 ~ 2 times a month, with no more than 75g each time.

Fourth, there are many pig blood toxins?

Want to supplement iron and blood, choose pig blood.

Blood products are safe as long as they are healthy pigs.

If you go to an informal place and accidentally buy dead pork or stale pig blood, that's another matter.

5. Is the cholesterol in pig brain high?

A few years ago, there was a suggestion that cholesterol should not exceed 300 mg per day. However, at present, it is agreed at home and abroad that the cholesterol content in food has little effect on the cholesterol content in the body and cardiovascular diseases, and the restrictions on cholesterol have been lifted one after another.

In order to be healthy, it is the key not to eat too much animal fat, not just cholesterol.

The cholesterol content of pig brain is really high. The cholesterol content in pig brain per 100g is as high as 257 1mg. However, 100 grams of fresh squid is only about 230 mg, and an egg yolk is only about 200 mg.

If you like, every month? Two or three times, each time? About 50 grams of pig brain, no problem.

Similarly, squid can still be eaten, and egg yolk can still be eaten. The world is really good.

6. Is there much dust in pig lungs?

There is a saying on the Internet that goes like this:

There are many alveoli in pig lungs, which are places for gas exchange and gather a lot of dust in the air, so there will be a lot of dust in pig lungs. In addition, pigs love to arch the ground and will inhale more dust, so pig lungs can't eat.

Let's talk about people first There is a disease called pneumoconiosis, which is only found in people at present.

It is mainly caused by long-term exposure to dust in the workplace and inhalation of a large amount of dust, which leads to dust accumulation in the peripheral bronchial alveoli.

But pigs are much happier than people! Also, pig farmers want them to gain weight in vain, and don't let them live too miserable or get sick. Even if pigs like to arch soil and cabbage, they will not suck soil into their bodies.

And they don't live in dusty places. After all, they don't have to work hard to make money. ...
