Grandma Wu, who pays attention to health care on weekdays, has been very worried recently, and she has inexplicably developed a large rash on her neck and arms.
Grandma Wu thought it was eczema at first, but after applying the ointment for a few days, it still didn't work. Grandma Wu was so anxious that her blood pressure was high.
In desperation, Grandma Wu hurriedly went to the hospital, but after seeing her condition, the doctor first asked about Grandma Wu's recent diet.
It turned out that Grandma Wu heard that celery and fungus were very healthy, which not only removed blood waste, but also lowered blood pressure. She has recently bought a lot of fresh fungus and celery, and has eaten almost every meal in the past month.
Who knew that the doctor's next words surprised Grandma Wu and broke her previous cognition.
1. High-fiber fruits and vegetables are not suitable for everyone
"The nutritional content of fungus is indeed very high, but it is not suitable to eat fresh fungus in large quantities for a long time. ”
While entering the medical record, the doctor explained to Grandma Wu: "Fresh fungus contains photosensitive substance porphyrin, which will be stored in our skin after eating too much fresh fungus, and you will have a rash due to light allergy when you go out on weekdays." ”
Grandma Wu touched the rash on her neck, and couldn't help but say with some fear: "I will definitely not eat fresh fungus in the future, so there is no problem with celery, right?"
"That's my second point," said the doctor, solemnly, "vegetables like celery or turnips should not be eaten much by the elderly. ”
Seeing that Grandma Wu was puzzled, the doctor talked about the emergency case some time ago.
A 60-year-old man was taken to the hospital in the middle of the night because of unbearable abdominal pain, and the doctor found that the old man's blood potassium level was extremely high, and he even suffered a cardiac arrest.
After asking his family carefully, he found out that the old man had a history of high blood pressure, because he heard that celery radish was a "natural antihypertensive drug", so he wanted to lower blood pressure in this "green and healthy" way. Who knew that the blood pressure did not go down, but instead collapsed the body.
For elderly patients with diabetes, cardiovascular and cerebrovascular diseases, long-term excessive consumption of high-potassium vegetables may lead to abnormal blood potassium, which can lead to serious symptoms such as myocardial ischemia and even cardiac arrest.
Grandma Wu's heart was cold after hearing this, and the doctor was busy explaining that it was not that she couldn't eat, but that she wanted to build a reasonable diet.
2. Reasonable eating habits
Daily eating habits are a big problem, and the daily diet of the elderly should follow three principles.
1. Eat small, frequent meals
As the saying goes, "Eat a meal that is full in seven", this is because after eating too much, the stomach pushes the diaphragm upward, which compresses the heart and increases the burden on the heart.
For the elderly with fragile cardiovascular and cerebrovascular diseases, eating smaller and more frequent meals will help the body's metabolic level to remain stable, reduce the amount of food eaten and thus reduce blood volume, and the amount of blood returning to the heart will be reduced. Therefore, eating less can reduce the load on the heart, and it is also helpful for the control of blood sugar and blood pressure.
2. More fruits and vegetables, less oil and salt
Many elderly people are accustomed to foods with more oil and salt, which is not advisable.
The daily salt intake of the elderly should be controlled within six grams, and if there are cardiovascular and cerebrovascular diseases, the salt intake needs to be controlled within two grams.
If you don't have an appetite, you can add more fresh fruits and vegetables. Fruits and vegetables are essential for vitamins and minerals, and fruits and vegetables rich in vitamin C have a sweet and sour taste, which can help appetize and increase appetite.
3. Reduce raw and cold diets
There must be many people who hear about raw and cold food, and what comes to mind is sorbet, chilled watermelon and other foods, but this is not the case.
Look at the temperature first, everything below the body temperature belongs to raw and cold food. For example, the food we take out from a low-temperature environment such as the refrigerator is considered raw and cold.
Then it comes down to the food attributes, which don't change depending on how it's cooked or processed. For example, bitter gourd and cucumber, even if they are fried and eaten, this ingredient is also cold.
It is important to note that the ingredients can be selected according to the season in different seasons, which helps the body adapt to the changes of the seasons.
3. Healthy cooking is important
Seeing that Grandma Wu listened carefully, the doctor continued to popularize science: "In addition to eating habits, the cooking method of dishes is also very important. ”
The digestive tract of the elderly is weakened, so the most suitable cooking method for the diet is steaming or boiling.
For example, vegetables with high oxalic acid content such as spinach and okra can retain their nutrients to the greatest extent by boiling, and they also taste good.
Steamed or boiled food can reduce the body's intake of salt and fat, rich dietary fiber can promote gastrointestinal peristalsis, and can also reduce sugar intake.
For high-protein foods such as meat, fish and shrimp, frying or grilling will denature the proteins, and the unsaturated fatty acids in the fat will be decomposed, which should not be absorbed by the human body.
Therefore, it is best to cook high-protein ingredients by steaming or stewing.
epilogue
After listening to this, Grandma Wu realized that health preservation is not about blindly listening and blindly following, but about developing reasonable eating habits and maintaining a diversified diet.
