Everyone hopes to age slower, but in life, some "aging agents" are hidden in our diet, which invisibly accelerate the aging of various organs.

1

Liver "Aging Agent": Alcohol

90% of alcohol (ethanol) oxidative metabolism occurs in the liver. During ethanol metabolism, more free radicals are produced, and excessive production of free radicals leads to oxidative stress.

Oxidative stress is one of the important factors leading to aging because it damages fat tissue, DNA and proteins, which in turn leads to age-related diseases.

Long-term alcohol abuse can easily lead to liver cell damage and induce various liver diseases. The safest amount of alcohol is 0. Only when you don't drink a drop can you be healthy.

Heart "Aging Agent": Trans Fats

A study published in JAMA Cardiology in 2017 pointed out that a comprehensive trans fat ban helps reduce the incidence of heart disease and stroke. Researchers from the University of Chicago School of Medicine and Yale School of Medicine compared the living conditions of people in the New York area and areas without trans fat restrictions. The study found that after three years or more of restrictions, people living in restricted areas had significantly fewer hospitalizations for heart disease and stroke than those in areas without restrictions. The overall difference was about 6.2%.

Trans fats come from two sources: natural foods and processed sources. The ones we need to control are mainly artificial ones.

Zhou Lin, director of the Clinical Nutrition Department of Kunming Children's Hospital, said: "In the ingredient list, artificial vegetable oil, margarine, margarine, shortening, non-dairy creamer are relatively common ingredients, all of which are artificial trans fats." Health authorities stipulate that the daily intake of trans fats per person should not exceed 2.2 grams, and excessive intake will be harmful to health. Therefore, it is better to eat less snacks and desserts. If you want to eat them, be sure to check the ingredient list before purchasing.

Skin "Aging Agent": Sweet Food

Zou Ying, deputy chief physician of the Department of Gynecology at Hunan Provincial Maternal and Child Health Hospital, said that many women are particularly fond of sweets, but eating too much desserts is very bad for health. Desserts contain high levels of sugar. Excessive sugar intake will accelerate skin aging, cause the skin to slowly lose elasticity, and become prone to a large number of wrinkles and spots.

In normal times, you should limit your intake of added sugar and refined sugar, such as eating less sweetened drinks, snacks, biscuits, and glutinous rice.

Stomach "Aging Agent": High-Salt Diet

The high osmotic pressure of table salt can cause direct damage to the gastric mucosa, resulting in a series of pathological changes such as congestion, edema, erosion, ulcers, necrosis and bleeding. It can also reduce gastric acid secretion, making the gastric mucosa vulnerable to attack.

Ma Guansheng, director of the Department of Nutrition and Food Hygiene at the School of Public Health at Peking University, said that when we eat high concentrations of salt, it will damage the gastric mucosa, become an "accomplice" of carcinogens, and increase the carcinogenic effect of carcinogens. More than 10 studies conducted in China, Japan, Italy, France, the United Kingdom, the United States and other countries have found that high salt and salted foods are risk factors for gastric cancer, which can increase the risk of gastric cancer by 2-6 times. Therefore, we should eat a light diet and eat less salted foods.

It is recommended to correct the habit of heavy flavors; use the flavor of vegetables themselves to enhance the taste of dishes; replace part of the salt and soy sauce with sour condiments such as vinegar and lemon juice; choose low-sodium salt, and be wary of hidden salt in seasonings and packaged snacks.

Esophagus "aging agent": hot food

Li Shujun, chief physician of the Department of Gastroenterology at Beijing Tsinghua Chang Gung Hospital, said that the surface of the esophagus is covered with delicate mucous membranes, and the temperature of food has a great impact on it: 10℃-40℃ is the most suitable; 50℃-60℃ is barely tolerable; above 65℃, it will cause burns. Don't think that 65℃ is too high, a hot dumpling can exceed this temperature. If the food temperature is too high, it will burn the esophageal mucosa and cause inflammation and necrosis, which may lead to cancer in the long run.

The human body's "sensitivity" of digestive organs such as the esophagus and stomach is relatively poor. Even if the esophagus is burned, the human body is unlikely to feel it, and even if there are minor lesions, it is not easy for us to detect. Therefore, the most suitable temperature for eating is neither cold nor hot, and our lips can just feel that it is warm, which is the most suitable. When eating, don't be too anxious, let it sit for a while, cool it down, and sip it with your mouth. When you feel it is no longer hot, then eat it.

Intestinal "Aging Agent": Improper Diet

Wang Xiaojun, deputy chief physician of the Department of Gastroenterology at Hubei Provincial Maternity and Child Health Hospital, said that the "intestinal age" of a normal person is not much different from his or her physiological age, but as people age, the pressure of life and work increases, coupled with improper diet, the number of beneficial bacteria in the intestines decreases, while the number of harmful bacteria continues to increase, eventually leading to intestinal flora imbalance and "aging" of intestinal function.

In the outpatient department of gastroenterology in some hospitals in Wuhan, young women who seek treatment for constipation account for half of the patients, and a considerable number of them have aging intestinal function. Wang Xiaojun said that the gastrointestinal tract is an important digestive and absorptive organ in the human body, and its peristalsis is regular. Many young people have a picky diet, excessive dieting, unscientific weight loss, alcoholism, smoking, and staying up late. These "unregulated" lifestyles bring great burden and stimulation to the gastrointestinal tract, causing their "intestinal age" to greatly exceed their actual age.

It is recommended to eat regularly and ensure the intake of dietary fiber, eat one pound of vegetables and half a pound of fruits every day, and one-third of the staple food should be coarse grains.

Lung "Aging Agent": Kitchen Fumes

Tao Xincao, a doctor from the Second Department of Respiratory and Critical Care Medicine of the China-Japan Friendship Hospital, said that the impact of kitchen fumes on people, at the very least, is that it can strongly irritate the nose, eyes, and throat mucosa, causing respiratory diseases such as rhinitis, pharyngitis, and tracheitis. Long-term inhalation of fumes can also lead to chronic obstructive pulmonary disease. In more serious cases, it may also cause symptoms such as loss of appetite, irritability, lack of energy, drowsiness, fatigue, etc., which is medically known as oil fume syndrome.

When cooking, you can't just turn on the range hood, it's best to open the kitchen window at the same time. Turn on the range hood for 10 minutes after cooking. Don't cook when you can eat stews and mixed vegetables, because cooking will inevitably produce a lot of oil smoke. You must cook, and control the oil temperature to 50% to 60% hot. That is, after the oil is put into the pot, take a small piece of onion skin and throw it into the pot. If there are many bubbles around the onion skin, put the ingredients into the pot before it changes color. In addition, clean the range hood filter once a month to avoid affecting the effect of extracting oil smoke.
