"Lao Li, eat less grapefruit, it's not good for your lungs."
Dr. Wang, a community doctor, said to Mr. Li, who was picking fruits, as he walked past the fruit stall.
Mr. Lee, 68, who worked as a construction worker before retiring, was addicted to smoking when he was young, and now his lung function is not as good as it used to be.
Today, he was picking up fruit at a fruit stall near the community, and happened to meet Dr. Wang coming to buy fruit.
Hearing the doctor's words, he was a little puzzled and hurriedly asked, "Why can't you eat more grapefruits?" ”
Dr. Wang patiently explained: Grapefruit is rich in vitamin C, which is a good thing for ordinary people.
But for people like you who have bad lungs, it can worsen the condition.
Then, Dr. Wang explained to Mr. Li in detail three kinds of fruits that people with bad lungs should eat less.
The first is grapefruit. Grapefruit is rich in vitamin C and a variety of minerals.
Although it can boost immunity, it also has something called naringin.
This substance inhibits enzymes in the liver, affecting the metabolism of some toxins in the body. This is followed by bananas.
Many people believe that bananas are good for the body, rich in potassium and dietary fiber, and good for the body's digestion and cardiovascular health.
However, bananas also contain a substance called tyramine, which may cause an increase in blood pressure.
For people with poor lung function, high blood pressure increases the burden on the heart, which in turn affects the oxygen supply to the lungs.
Doctors cited a study involving 2,000 people that found an association between a diet high in potassium and decreased lung function.
Especially for those who already have lung disease.
Finally, there are the grapes. Grapes have many antioxidants and vitamins, but they are also not low in sugar.
A diet high in sugar can lead to an increased inflammatory response in the body, which is very detrimental for people with chronic inflammation in the lungs.
Studies have shown that diets high in sugar can worsen symptoms in people with COPD, increase airway resistance, and lead to poor breathing.
After listening to the doctor's explanation, Mr. Li couldn't help frowning and said, "Then what kind of fruit can I usually eat?" ”
Dr. Wang smiled and comforted him: Don't worry, it's okay to eat in moderation, just don't overdo it.
Also, you can choose some fruits that are good for your lungs, such as apples and pears.
Apples are rich in antioxidants and dietary fiber, which help protect the lungs and reduce inflammation.
Pears, on the other hand, have the effect of moistening the lungs and relieving coughs, which is very suitable for your situation.
Dr. Wang also told a case: Aunt Zhang, 75 years old this year, has been suffering from emphysema for a long time.
She used to enjoy eating grapes and bananas, but as emphysema was getting worse, doctors advised her to adjust her diet.
Aunt Zhang now eats less fruits that are high in sugar and potassium, and eats apples and pears instead.
As a result, my lung symptoms improved significantly, and my breathing became much easier.
Mr. Li nodded and understood.
In addition to diet, what other aspects should people with poor lung function pay attention to in their daily lives?
First of all, it is very important to maintain good air quality and avoid exposure to some smoke.
The home should be ventilated frequently to keep the air fresh.
Secondly, exercise moderately, but avoid strenuous exercise so as not to increase the burden on the lungs.
Choosing some aerobic exercise that is not strenuous and does some kind of exercise, such as walking and tai chi, is good for improving lung capacity.
Finally, regular health check-ups, especially pulmonary function tests, are needed to keep abreast of your physical condition for early detection and treatment.
Hope it helps, thank you!
