Lao Wang is a retired secondary school teacher who is 68 years old. For more than a month, he always felt chest tightness and shortness of breath, dry cough without phlegm, and his physical strength was not as good as before.
His wife, Aunt Zhang, dragged him to the hospital. Dr. Liu inquired about Wang's living habits and examined him.
The results found that Lao Wang's lung function decreased slightly, and his blood lipid and blood sugar levels were high.
Dr. Liu said: "Lao Wang, from the current situation, your respiratory symptoms may be related to the decline of lung function, but it cannot be ruled out that they are caused by cardiovascular diseases. It is recommended that you go to a major hospital for further examinations such as chest CT and electrocardiogram to determine the cause. ”
"At the same time, I also noticed that your blood lipids and blood sugar are a little high, which may be related to unreasonable eating habits. Do you have any favorite foods?"
Lao Wang smiled embarrassedly and said, "I have loved duck eggs since I was a child, especially salted duck eggs." Originally, when I was young, I didn't eat much, but after retirement, I loved to make a pot of tea and eat salted eggs, which felt very comfortable. ”
"Yesterday I had a fight with my wife, and she said that I had a bad appetite lately, and my cough was also due to eating too many duck eggs. How can I believe her! The duck eggs are so good, I've been in good health since I was a snack to a big one!"
Dr. Liu shook his head with a smile and said earnestly: "Lao Wang, your view is biased. Duck eggs are indeed a nutritious food, and eating them in moderation is beneficial to the body. ”
"But if you eat too much, especially salted duck eggs, it will bring health risks. There are two main reasons:"
"Salted duck eggs are high in sodium. Excessive intake of sodium salt will increase the burden on the kidneys, cause water and sodium retention, and induce cardiovascular diseases such as hypertension and heart failure. ”
"For the elderly, kidney function is already declining, and eating too salty is even worse. Other studies have found that a high-salt diet is also associated with lung infections and decreased lung function. “
"Duck eggs have a high cholesterol content, and long-term consumption of large amounts will increase the risk of cardiovascular and cerebrovascular diseases. Middle-aged and elderly people with high blood lipids like you should pay more attention to controlling cholesterol intake. "
"So, I recommend that you change your eating habits from now on and eat less salted eggs. Usually eat more vegetables and fruits, and eat less high-salt, high-fat foods. ”
"As for whether duck eggs can 'clear the lungs and relieve cough', I think there is still a lack of reliable medical evidence. Whether your cough is caused by lung problems or a sign of cardiovascular disease needs to be clarified. ”
"But in any case, controlling the amount of duck eggs consumed is always beneficial and harmless in relieving symptoms."
Lao Wang suddenly realized, and nodded again and again to indicate that he remembered the doctor's instructions. He decided to go back and give a box of salted duck eggs to his neighbors at home, and eat it lighter himself, and then "prescribe the right medicine" after finding out the cause of the disease.
Many middle-aged and elderly people often listen to some specious "folk experience" and feel that certain foods have special "medicinal value", so they eat a large amount, which is counterproductive.
As everyone knows, no food has the miraculous effect of "curing all diseases", and excessive consumption will bury hidden dangers to the body.
Although duck eggs are nutritious, they should also be done in moderation. Especially salted duck eggs, the amount of consumption must be strictly controlled.
Middle-aged and elderly people are already at a high incidence of cardiovascular disease and kidney disease, and if they eat too salty, it will increase the burden on the body.
As for whether duck eggs can "clear the lungs and relieve cough", there is no authoritative clinical research to confirm it. From a nutritional point of view, although duck eggs are rich in nutrients such as vitamin A and selenium that are beneficial to respiratory health, the main components are similar to those of eggs and there is no special feature.
Most of the claims known as "duck egg white lungs" lack scientific basis and cannot be blindly followed.
For middle-aged and elderly people, the diet should be light and balanced, less salt and less oil, more vegetables and fruits, and at the same time, regular physical examinations, pay attention to physical changes, and seek medical attention in time when encountering problems.
In this way, we can enjoy the worry-free "food" and the healthy fun of "food" in our later life.
Do you have anything to say about that?
