"Lao Li, have you heard? Middle-aged and elderly people better not eat preserved eggs, this thing is not good for us!"
On a bench in the community park, Mrs. Zhou brought up the topic to her old friend Lao Li. Lao Li, a retired postman, frowned after hearing this. He has always liked to eat preserved egg tofu, and this sudden news made him a little uneasy.
Early the next morning, Lao Li went to the hospital in high spirits, hoping to get a definite answer from professionals. In the outpatient room of the hospital, sits Dr. Wang, an experienced digestive specialist. Dr. Wang looked at Lao Li, who came to consult, and patiently explained: "Preserved eggs are indeed a bit particular, especially for middle-aged and elderly people, they should indeed eat less. ”
Lao Li asked curiously, "Doctor Wang, why are preserved eggs bad for us?" Dr. Wang smiled slightly and began to explain in detail: "First of all, the lead content in preserved eggs may be a problem. Although the use of lead preparations in modern preserved eggs has been greatly reduced, the possibility of lead cannot be completely ruled out. ”
"Lead is a heavy metal, and long-term ingestion of small amounts of lead may affect the blood system and cause lead poisoning. Especially in middle-aged and elderly people, it is more difficult to excrete the lead accumulated in the body due to the slowdown of metabolism. ”
"In addition, the high sodium characteristics of preserved eggs are also a consideration. You know, high-salt foods are one of the main culprits that cause high blood pressure. Hypertension is the main risk factor for cardiovascular and cerebrovascular diseases, and we should be especially careful with middle-aged and elderly people. Dr. Wang said as he took out some relevant reports from the drawer and showed them to Lao Li.
Dr Wong says that an average daily intake of more than 5 grams of salt increases the risk of high blood pressure by nearly 25 percent. The sodium content of a preserved egg is about 300 mg, which is not particularly high, but if it is not eaten properly, it can easily lead to excessive total intake.
"Another thing that should not be ignored is the high nitrite formed during the curing process of preserved eggs. Nitrite is converted into nitrosamines in the body, and long-term intake of nitrosamines may increase the risk of certain types of cancer. Dr. Wang went on to explain that his words reveal a deep concern for the health of his patients.
Lao Li listened with relish, and he felt that his eating habits for many years might really need to be adjusted. He asked again, "So how should I adjust my diet?"
"Actually, it's all about balance. I recommend that you eat more vitamin- and mineral-rich foods, such as fresh vegetables and fruits, and reduce your intake of processed foods and high-salt foods. At the same time, increase physical activity appropriately to help boost metabolism. "Dr. Wang is very attentive in his advice.
After half an hour of communication, Lao Li finally left the hospital satisfied. He understood that although preserved eggs were good, they really couldn't be greedy. This small dietary change may be his first step towards a healthier life.
A few months later, Lao Li shared his experience with his neighbors at a community health lecture: "Eat less preserved eggs, walk more, and your body is great!" The old friends around him were attracted by his humorous tone and simple explanations. Over time, Lao Li found that his blood pressure had indeed improved, and his experience became a small legend in the community.
When Lao Li came to the hospital that day, he thought of a question and asked the doctor: "Dr. Wang, I had a major operation before, and some metal materials were used in my body at that time, will this have anything to do with the accumulation of lead?"
Dr. Wang reviewed Li's medical records in detail and explained, "Don't worry, the materials used in the surgery are all biocompatible materials that have been carefully screened and do not interact with lead accumulation in the body. But this question of yours is very good, regular check-ups and understanding your health are what everyone should do. ”
Lao Li nodded, feeling more relieved. He knows that as long as he continues to pay attention to his health and adjust his diet reasonably, a healthy and long life is not an unattainable dream.
