The World Health Organization says that "red meat causes cancer", so many people think that vegetarian food can lead to longevity. At the Heart Failure and World Conference on Acute Heart Failure, a study said that older adults who consumed higher proteins, the main sources of which were meat and eggs, had a lower risk of cancer. So, eating meat, eating vegetarian, which is more likely to get cancer?
Especially at the end of the year, the debate about eating meat and eating vegetarian longevity is even more rampant. Which is better? And look at the editor slowly.
Nature: Meat-eating animals are susceptible to cancer! What about people?
On December 22, 2021, researchers at the Ecological Research Center in Debrecen, Hungary, published a research paper entitled "Cancer risk across mammals" in the leading journal "Nature". The new study suggests that diet can have a large impact on cancer risk.
The study found that carnivorous animals are susceptible to cancer, and ungulates are not prone to cancer! Specifically, more than 25% of carnivores that feed on other mammals, such as clouded leopards, red wolves, bat-eared foxes, etc., die of cancer. Ungulates, including antelopes, sheep and cattle, are the least susceptible to cancer.
Distribution of risk of cancer death in mammalian phylogeny
The researchers believe that the high cancer risk of carnivorous mammals may be related to their low microbiome diversity, limited physical exercise in human care, carcinogenic viral infections, or other physiological aspects of carnivorous mammals.
But carnivorous mammals are more susceptible to cancer, which does not mean that meat-eating people are also more likely to develop cancer, because our lifestyle (habits, environment, schedule, etc.) is different from other mammals and is not inclined to eat raw meat.
Are humans healthier at eating meat or going vegetarian?
Opinions on whether humans eat meat or eat vegetarian health are currently different. The following studies or statements can be found:
Is there a scientific basis for "red meat carcinogenicity"?
Red meat, as the name suggests, is red meat, which is rich in heme iron, including pork, beef, lamb and so on that we eat every day. At present, the World Health Organization has classified red meat as a Class 2a carcinogen, clarifying its health risks.
BMC Medicine published a study led by Tel Aviv University in Israel, in which researchers found a direct molecular link between a sugar present in red meat and dairy products and the development of antibodies in the blood, which increase the incidence of cancer.
People who consume large amounts of red meat produce high levels and different types of antibodies that increase the risk of cancer, especially colorectal cancer.
A joint survey spanning 11 countries: People who eat more meat live longer!
At the World Congress of Heart Failure and Acute Heart Failure, a joint study across 11 countries found that a higher intake of protein, the main source of which is meat and eggs, has a lower risk of cancer and can live longer than the elderly who eat more vegetarian.
The experiment found that the mortality rate of the elderly who took more than 40 grams of protein per day was only 18%, while the elderly who consumed less than 40 grams had a mortality rate of 31%!
Here, Xiaobian would like to say that it is okay to eat meat appropriately, but the proportion of red meat intake should still be controlled.
Why do people naturally prefer to be vegetarian?
Carnivores have evolved a series of genes that can quickly convert toxic ammonia into non-toxic urea in the liver and excrete it. This process, called the "urea cycle," is one of the body's most important detoxification mechanisms. So, every time you pee is really detoxifying.
But some people don't detoxify very well, such as people with OTC gene mutations. Eating too much protein in this category is risky. Because proteins enter the body to metabolize large amounts of ammonia. And this "ammonia" is neurotoxic.
Therefore, such people eat vegetarian, not for the sake of the trend, but for the sake of life. Some people who are naturally vegetarian do not have to force themselves to eat meat.
Collagen supplementation can prevent breast cancer!
A recent study published in the medical journal Advanced Science shows that collagen supplementation can be effective in preventing breast cancer.
The paper found that in aging mammary glands, collagen production decreased and collagen fibers became thinner and more curled. Originally, the cancer cells had to pass through the shackles of the collagen network to metastasize and invade, and the collagen fibers became thin and curled, and the collagen network was out of the hole, and the cancer cells metastasized easily.
So what can you eat to supplement collagen? The foods that supplement collagen are mainly some animal foods, such as pig trotters, pig skin, fish glue, bird's nest, white fungus and so on.
How to eat healthier with meat and vegetarian combinations?
Whether to eat vegetarian or meat, in fact, it is still based on individual circumstances. It is best to combine meat and vegetables to achieve a certain balance. So how to make meat and vegetarian combinations healthier, it is recommended to do the following:
How to eat healthy?
Eat less red meat and often white meat. According to the "Dietary Guidelines for Chinese Residents", the daily intake of red meat is best controlled within 50g; white meat includes chicken, duck, fish, etc., relatively speaking, the fat content is relatively small, which helps to control blood lipids.
It is best not to eat processed meat and cured meat. Processed meat contains a certain amount of nitrite, which may produce trace amounts of carcinogen nitrosamines, increasing the risk of cancer; like bacon, salted chicken and other cured meat, excessive intake will indirectly increase the risk of esophageal cancer and stomach cancer.
Pay attention to how you cook. Try to use less frying, frying, and baking. Relatively speaking, stew is more recommended, low heat slow simmering, can reduce saturated fat.
Add "best partner" to meat. Meat is added with vegetables rich in dietary fiber: konjac, dried pine mushrooms, dried mushrooms, bamboo shoots, etc., which can help inhibit fat absorption; mushrooms such as shiitake mushrooms and chicken leg mushrooms are stewed with meat, which not only tastes good, but also alienates cholesterol.
Write at the end
In life, in addition to germs and genetic factors that may make us sick, poor diet is also one of the key causative factors. Bad eating habits, or irrational dietary structures, can leave our physical health in an imbalance. In the long run, various diseases will also occur.
It is good to eat vegetarian food, or it is good to eat meat, can not be generalized. But in general, meat and vegetarian combination is the best!
