Uncle Li is 74 years old this year, has been retired for many years, and has been engaged in the profession of a postal clerk, the kind of person who delivers letters on a bicycle.
For more than ten years, he insisted on not eating MSG and soy sauce, because one day after seeing a program on TV about "less salt and less oil is healthier", he decided to change his eating habits.
Walking into the physical examination center, Uncle Li's figure looked a little short, but his pace was steady. He was greeted by a young doctor, Dr. Zhang, who is well-versed in nutrition and has a unique perspective on the health of the elderly.
"Uncle Li, what are you doing this time?" asked Dr. Zhang with a smile. "Hey, I'm here for a comprehensive check-up, I haven't eaten MSG or soy sauce in the past few years, I want to see how my body is. ”
Uncle Li said as he took out a worn-out physical examination card from his old-fashioned backpack. From blood routine to electrocardiogram to liver and kidney function, it takes some time to get results after a series of tests.
"Uncle Li, you don't eat MSG and soy sauce, so what is your usual diet?" Dr. Zhang asked curiously. "Oh, I mainly eat some home-cooked food, steam and cook more, and try not to put oil and salt. I've heard that this is good for the body. Uncle Li explained.
Dr. Zhang smiled slightly, and had a plan in mind. "Actually, Uncle Li, there are many people who have some misunderstandings about diet and health. Avoiding it altogether may make the diet lack certain essential amino acids and trace elements. ”
Next, Dr. Zhang explained in detail the effects of monosodium glutamate on the human body and how the amino acids and trace elements contained in soy sauce help the body maintain normal physiological functions. The key, he stressed, is to do it in moderation, not to avoid it entirely.
Subsequently, Uncle Li's indicators were basically normal, but vitamin D was slightly lower, which is more common in the elderly, especially those who do not get regular sun exposure or have an unbalanced diet.
"Look, Uncle Li, your overall physical condition is good, but you don't have enough vitamin D. You can improve by getting sun exposure and adjusting your diet. Dr. Zhang advised. Uncle Li listened very carefully, and he wrote down all the suggestions. He began to realize that a single diet does not guarantee complete health, but requires a variety and balanced nutrition.
At the end of the conversation, Dr. Zhang also mentioned some similar cases he had come into contact with, in which patients suffered from varying degrees of malnutrition due to a single diet for a long time.
In some patients, the intake of fat-soluble vitamins is insufficient because of the complete elimination of fats, which affects the body's immune function. Others do not eat any additives, which leads to a deficiency of trace elements.
Dr. Zhang reminded Uncle Li: "The body needs not only the type of food, but also the right amount of nutrients. For example, calcium and iron intake are extremely important for maintaining bone and blood health, and these trace elements are available in daily vegetables and meat. ”
Through in-depth conversations with Dr. Zhang, Uncle Li gradually understood that a healthy lifestyle is not only about avoiding certain foods, but more importantly, eating a varied and balanced diet.
This new realization surprised and excited him at the same time as it changed the eating beliefs he had held for years. After the medical examination, Uncle Li decided to re-evaluate his eating habits.
He began to try to follow Dr. Zhang's advice and gradually introduce some previously avoided ingredients, such as soy sauce and seafood, in order to get more amino acids and trace elements. A few months later, Uncle Li returned to the hospital with anticipation for another physical examination.
He was ecstatic with the results – not only had his vitamin D levels improved significantly, but his other nutritional indices were also more balanced. With a smile on his face, he expressed his heartfelt gratitude to Dr. Zhang.
"Dr. Zhang, you have been a great benefactor to me, your advice has not only made my body healthier, but more importantly, it has given me a new understanding of how to maintain my health. Now I'm full of energy and I feel like I'm so much younger again. ”
Dr. Zhang responded with a smile, "Uncle Li, I am very happy to see your changes and progress. Health is always a marathon that requires us to constantly adjust and adapt. Remember, moderation and balance are the most important principles of diet. ”
