"Grandma, I beg you, don't hoard lard at home anymore, we haven't finished the lard we squeezed during the Chinese New Year. ”
"What do you know, lard is a good thing, if you didn't always make lard bibimbap for you when you were a child, you would have been so tall?"
Lily protested with her grandmother for five minutes against the "lard" at home!
"If you eat lard, you will become ugly! you will get fat~"
"If you store so much, you will waste it if you can't eat it all. ”
"By the way, lard causes cancer, I've seen this news!"
In the end, it ended in the victory of grandma.
After Lily returned to the room angrily, she immediately looked for evidence, after all, there was no basis for her words, and she must convince her grandmother this time.
So: is eating lard good for your health?
1. Does lard cause cancer and hurt the cardiovascular system? Tell you the truth
Where did the rumors of carcinogenicity from lard come from?
Huazhong University of Science and Technology has done relevant experiments with healthy mice. It shows that some components in lard are resistant to insulin, which is one of the risk factors for cancer.
In addition, there are experiments in South Korea that show that long-term intake of lard in mice stimulates the development of prostate cancer.
Hence the claim that "lard causes cancer". However, the limitation of these two trials is that they were all conducted around animals, and it would be very unscrupulous to conclude that lard causes cancer in humans.
And: According to the BBC, after analyzing thousands of ingredients, the researchers ranked the 100 kinds that can best meet the daily nutritional balance needs, and one of them is eye-catching: lard beats more than 990 ingredients, entering the top ten, ranking eighth!
Lard beats the recognized healthy foods such as broccoli and sea bass in our daily life.
In addition, lard also contains 47.5% monounsaturated fatty acids and 11.5% polyunsaturated fatty acids, which are beneficial for regulating blood lipid levels and assisting in the prevention of cardiovascular diseases.
The digestion and absorption rate of lard in the human body is higher, up to more than 95%, it is a seasoning with high content of vitamin A and vitamin B, and the proportion of fat contained in it is less than that of butter, and it is also suitable for people and children who lack vitamin A.
Therefore, the rumors that lard causes cancer and injures the cardiovascular system are all wrong!
Attending physician Wang Qingwen, head of the Department of Clinical Nutrition of the Affiliated Hospital of Traditional Chinese Medicine of Southwest Medical University, said:
At present, there is no research to prove that lard causes cancer, and lard is a relatively rich type of food, in the case of meeting the needs of the human body, the intake of appropriate ingredients will be beneficial to health!
Second, the older generation often eats lard, what happened in the end?
In the last century, lard was very precious.
In the past, people's overall fat intake was not high, their living conditions were limited, and they needed to engage in high physical labor and consume a lot of calories, so eating lard became a precious way for people to supplement nutrition.
There is even a saying that "a spoonful of lard is equal to five medicines", which is confirmed in the "Compendium of Materia Medica".
In the case of symptoms, lard has the effect of improving gastrointestinal function, facilitating urination, removing edema and other effects.
Not only are there records in ancient books, but modern scientists have also discovered these three nutrients in lard.
1. Vitamins
One spoonful of lard contains 1,000 international units (IU) of vitamin D, second only to cod liver oil. In addition, lard also contains vitamin A, vitamin B and other essential vitamins for the human body.
2. Fatty acids
Fatty acids are mainly divided into saturated fatty acids and unsaturated fatty acids (which are further divided into monounsaturated fatty acids and polyunsaturated fatty acids).
Excessive intake of saturated fatty acids increases the risk of cardiovascular disease and death, while increasing the intake of unsaturated fatty acids can reduce the incidence of cardiovascular diseases.
One spoonful of lard contains about 5g of saturated fat, 5.8g of monounsaturated fat and 1.4g of polyunsaturated fat. So in terms of fat composition, the unsaturated fat content of lard is just between butter and olive oil.
3. Minerals
The main nutritional value of lard is to provide the body with oils and fat-soluble vitamins. From the perspective of nutritional analysis, 100 grams of lard contains the most fat, 88.7 grams, about 4 grams of water, rich in fat-soluble vitamins, lard also contains a small amount of minerals, 0.8 mg of zinc, 0.05 mg of copper, has a good effect on growth and development.
3. These 4 kinds of oil are harmful oils
The real harm in the daily diet is these four oils:
1. Long opening time
Edible oil has been disassembled for a long time, but it is still used, and many people have this habit. This kind of oil that has been opened for a long time will increase the risk of mold infection of the oil, because after opening for a long time, the oil and the oxygen in the air come into contact, and the oxidation reaction may occur, producing some oxidation products. After consumption, symptoms of nausea, vomiting, diarrhea and other poisoning symptoms may occur.
2. High number of uses
After frying the food, I feel that it is a waste to throw it away, so I use it again next time and eat it repeatedly. This kind of oil that has been fried many times is easy to produce carcinogens such as benzopyrene, heterocyclic amines and acrylamide, and there are health risks when consumed for a long time.
3. It smells bad
After a long time, edible oil is easy to produce a "hala smell", in fact, this hala smell is the result of oxidation reaction. If the hala smell has been produced, it means that aldehydes and ketones have probably been produced, and long-term consumption may increase the burden on the liver and kidneys.
4. Small workshop production
Many families have the habit of eating self-pressed oil, and feel that this oil is more authentic and tastes better. As everyone knows, this self-pressed oil is prone to health risks, such as excessive aflatoxin. As a first-class carcinogen, aflatoxin is harmful to imagine, so it is best to eat less self-pressed oil.
