Everyone wants aging to come more slowly, but there are always some things in life that invisibly accelerate the aging rate of various organs, such as the food we eat in our mouths every day.
Life Times (search for "LT0385" in WeChat to follow) interviews experts, points out the "aging agents" hidden in food, and teaches you how to avoid disease from entering the mouth.
Experts interviewed

Cardiac "aging agent": trans fatty acids
Trans fatty acids can lead to an increase in LDL cholesterol ("bad" cholesterol) and lower HDL cholesterol ("good" cholesterol), increasing the risk of heart disease.
The source of trans fatty acids can be divided into natural and synthetic two, we need to control the main synthetic.
Common foods containing trans fatty acids include cream pastries, chocolate pie, puff pastry, wafer biscuits, sandwich cakes, egg yolk pie, cocoa butter chocolate products, ice cream, french fries, etc.
Dodge the trick
When buying food, you can focus on the ingredient list.
Ingredients labeled with artificial fats, margarine, vegetable cream, creamer, cocoa butter, refined vegetable oil, shortening, artificial ghee, vegetable fat powder, etc., may contain trans fatty acids, so try to choose less.
Liver "aging agent": alcohol
Alcohol is the enemy of liver cells, and after it enters the body, it needs to be metabolized through the liver. In this process, alcohol not only interferes with the normal metabolism of nutrients, but also affects the detoxification function of the liver. At the same time, alcohol can directly damage liver cells and induce various liver diseases.
Dodge the trick
The safest amount of alcohol to drink is 0, and one drop is healthy.
Adults who have to drink alcohol should strictly limit the amount. The recommended daily drinking limit is: 1 beer (350 ml) or 150 ml of red wine or 25 to 50 ml of white wine.
Skin "aging agent": fructose
Some people eat fruits instead of meals for weight loss and beauty, and for a long time, too much fructose intake will accelerate aging. Moreover, long-term fruit replacement meals will lack essential fatty acids and fat-soluble vitamins, and in severe cases, they can suffer from toad skin disease, which is manifested by dry and rough skin and pimples.
Dodge the trick
Fruits can be eaten 200 to 350 grams per day, and the intake of foods with added fructose syrup should also be restricted, such as juice drinks, jelly, preserved fruits, etc.
Eye "aging agent": sweets
After sweets enter the body, they are acid-producing foods, which consume alkaline elements such as calcium and chromium when metabolized. When calcium and chromium are insufficient, the elasticity of the eyeball wall is reduced, normal intraocular pressure cannot be maintained, and excessive intake of sweets will also cause changes in the osmolality of the lens and aqueous humor, which will aggravate eye damage.
Dodge the trick
In addition to a variety of sweets, sweets also include biscuits, cakes, ice cream, milk tea juices, milkshakes, etc., all of which must be restricted.
Stomach "aging agent": high-salt foods
Long-term high-salt diet will cause gastric mucosal cells and external osmotic pressure to increase, damage the gastric mucosa, so that it will occur extensive diffuse congestion, edema, erosion, ulcers and other pathological changes, increasing the risk of gastric mucosal cells cancer.
Dodge the trick
The World Health Organization recommends that healthy people should not eat more than 5 grams of salt per day, and patients with hypertension should be controlled at 2 to 3 grams per day. People with normal kidney function can replace table salt with low sodium salt.
Esophageal "aging agent": hot food
The mucous membranes on the surface of the mouth and esophagus are sensitive to temperature and can burn the mucous membranes beyond 65 ° C. The habit of hot food not only damages the esophagus, but also has a long-term risk of causing cancer.
Hot drinks above 65 °C have been listed as Class 2A carcinogens by the International Agency for Research on Cancer, and existing animal experiments have also confirmed that hot drinks of 65 °C to 70 °C are enough to burn the throat and may lead to esophageal cancer.
Dodge the trick
When eating, be sure to wait until it is not hot before eating. People who are accustomed to hot food are not sensitive to temperature, and they should change the habit of eating hot food.
In addition, in order to protect the esophagus, attention should also be paid to eating less raw and cold stimuli and foods that are too sour and too spicy to cause gastroesophageal reflux. ▲
