Dr. Li sat in the consultation room, flipping through the medical records in his hand, his brow furrowed slightly.
The last patient of the day is Uncle Wang, a 71-year-old retired teacher, who came to the clinic with recent symptoms of dizziness and fatigue. "Uncle Wang, please come in and sit." Dr. Lee greeted with a smile.
Uncle Wang slowly walked into the consultation room, sat down and began to tell his symptoms: "Doctor Li, I have always felt dizzy and weak for the past two months, and I have not slept well, I don't know what is going on. "
Dr. Li carefully inquired about Uncle Wang's living habits and diet. During the conversation, he noticed that Uncle Wang mentioned that he was particularly fond of sweet potatoes and had to eat one or two almost every day.
"Uncle Wang, do you usually eat a bit too much sweet potatoes?" Dr. Lee asked.
Uncle Wang smiled: "Yes, I have liked to eat sweet potatoes since I was a child, I think they are sweet and delicious, and I heard that sweet potatoes are nutritious and good for the body." "

I know it might be a little intrusive, but it does help me increase my income and keep me writing. Your understanding is my biggest motivation, and I will try to bring more quality content!
Dr. Lee nodded and explained, "Sweet potatoes are indeed rich in nutrients, but for the elderly, excessive consumption can cause some problems. I recommend that you do a thorough medical check-up first to see if there are any other problems. "
Subsequently, Uncle Wang underwent a series of examinations. The results showed that he had slightly higher blood sugar levels, low potassium levels, and mild anemia.
Dr. Li carefully analyzed the results of the examination, combined with Uncle Wang's symptoms and eating habits, and came to a preliminary diagnosis.
"Uncle Wang, your symptoms are likely to be related to long-term consumption of large amounts of sweet potatoes." Dr. Lee explains, "Although sweet potatoes are highly nutritious, they also contain a lot of carbohydrates, which can cause a rapid rise in blood sugar.
For older people, this can increase the risk of diabetes. Uncle Wang showed a surprised expression: "I always thought that sweet potatoes were healthy food, but I didn't expect there to be such a problem." "
Dr. Lee continued, "In addition, sweet potatoes contain oxalic acid, which can affect calcium absorption, and long-term consumption may lead to osteoporosis.
Also, the tannic acid in sweet potatoes can affect iron absorption and may cause anemia. Your current mild anemia may be related to this. "
After listening to this, Uncle Wang asked with some concern: "Then I can't eat sweet potatoes in the future?" Dr. Li smiled and replied, "It doesn't have to be completely banned, but it needs to be in moderation."
It is recommended that you do not consume sweet potatoes more than twice a week, no more than 100 grams each time. In the meantime, I'll create a more balanced diet plan for you. "
Next, Dr. Li introduced to Uncle Wang in detail the dietary principles suitable for the elderly. The importance of protein was emphasized, and it was suggested that Uncle Wang should eat more lean meat, fish, eggs, beans and other high-protein foods.
At the same time, he also recommends some vegetables and fruits that are rich in vitamins and minerals, such as broccoli, spinach, citrus, etc.
"In addition to adjusting your diet, it's also important to exercise moderately." Dr. Lee adds, "I recommend that you do 30 minutes of light aerobic exercise every day, such as walking or tai chi. This helps to improve blood circulation and strengthen physical fitness. "
Uncle Wang listened attentively and nodded from time to time. He said, "Dr. Lee, I understand. It seems that I will have to pay more attention to my diet and lifestyle habits in the future. "
Dr. Lee smiled with relief: "Yes, maintaining a balanced diet and a healthy lifestyle is essential for the health of the elderly. We'll review it regularly to see if your metrics are improving. "
After seeing off Uncle Wang, Dr. Li fell into deep thought. As a senior doctor, I know that many seniors have misconceptions about eating healthy.
It is not uncommon for Uncle Wang to overeat a certain food. He decided to write an article to educate more people about healthy eating for the elderly.
Dr. Lee first emphasised the importance of a balanced diet, there is no absolute "good" food or "bad" food, the key is to eat it in moderation and balance.
For sweet potatoes, he explained, it is indeed rich in vitamins A, C and dietary fiber, but there are a few things that the elderly need to pay attention to when eating them.
Sweet potatoes contain a lot of carbohydrates, which can cause a rapid rise in blood sugar, and it is necessary to be extra cautious for diabetics or older adults with poor blood sugar control.
The oxalic acid in sweet potatoes may affect calcium absorption and increase the risk of osteoporosis. Furthermore, the tannic acid in sweet potatoes can affect iron absorption, which may lead to anemia.
Dr. Li advises that the elderly should consume sweet potatoes in moderation, no more than twice a week, and no more than 100 grams each time.
At the same time, he also reminded readers that the statement circulating on the Internet that "you completely abstain from eating sweet potatoes after the age of 70" is a bit exaggerated. As long as consumed in moderation, sweet potatoes are still a nutritious food.
Dr. Lee also discussed the foods that the elderly should eat more, especially emphasizing the importance of high-quality protein, and advised the elderly to eat more lean meat, fish, eggs, legumes, etc.
These foods help maintain muscle mass and prevent muscle atrophy. In addition, fruits and vegetables rich in vitamins and minerals, such as broccoli, spinach, carrots, citrus, etc., are also indispensable.
Dr. Lee also mentioned some common dietary misconceptions among older adults. For example, some older people think that eating as light as possible can actually lead to malnutrition.
Some elderly people like to consume a certain kind of "health" food for a long time, but neglect to have a balanced overall diet. He stressed that the diet of the elderly should be rich and varied to ensure complete nutrition.
At the end of the article, Dr. Lee urged everyone not to blindly believe the dietary advice circulating on the Internet.
It is recommended that the elderly have regular medical check-ups and develop a suitable diet plan based on their own health status and the doctor's advice.
At the same time, he also emphasized the importance of moderate exercise, encouraging the elderly to stick to light aerobic exercise, such as walking, tai chi, etc.
Many readers said that through this article, they have gained a more comprehensive understanding of the dietary health of the elderly.
Some elderly readers also shared their experiences of improving their physical condition after adjusting their diet in the comments.
Dr. Lee's article not only corrects some common dietary misconceptions, but also provides practical advice for healthy eating for the elderly.
He hopes that through such popular science articles, more elderly people can establish a correct concept of diet and enjoy a healthy life in old age.
