There is a small but cozy bookstore in the busy city center, and the proprietress here, Sister Zhang, is a 63-year-old lady with a warm personality and loves to laugh.
She likes to make a pot of tea and read a good book in her spare time.
Recently, however, she noticed that she was always feeling weak and her bones aching, and she thought it was a common geriatric illness until her family doctor recommended that she go to the hospital for a full check-up.
"Sister Zhang, these symptoms of yours may be caused by malnutrition, I suggest you go to the hospital for a detailed blood test." The doctor gently advised.
During an examination at the hospital, doctors found that Sister Zhang's body was deficient in two important nutrients: vitamin B12 and omega-3 fatty acids.
This discovery surprised Sister Zhang, because she has always believed that her diet is healthy.
"You haven't eaten eggs in nearly 20 years?" The doctor asked curiously.
Sister Zhang nodded, she had been avoiding all eggs and egg-containing foods because she was allergic to eggs when she was young.
Doctors explain that vitamin B12 is mainly derived from animal foods such as meat, fish, dairy products and eggs.
Long-term vitamin B12 deficiency can lead to a variety of health problems, including blood disorders, nervous system damage, and physical fatigue.
Omega-3 fatty acids, commonly found in fish and some vegetable oils, are essential for heart health, anti-inflammatory, and brain health.
"I don't really eat much fish, I thought tofu and vegetables would be enough." Sister Zhang said helplessly.
Here, we get an interesting point: even a seemingly healthy vegetarian diet can lead to a deficiency of important nutrients if not properly planned.
According to surveys, more than 30% of older vegetarians may experience vitamin B12 deficiency without supplementation.
In Western countries, omega-3 fatty acid deficiencies are becoming more common due to the decline in the general diet of fish, which poses a threat to cardiovascular and cerebrovascular health.
When treating Zhang's nutritional deficiencies, the doctor advised her to start taking vitamin B12 and omega-3 fatty acid supplements and try to gradually increase the proportion of fish in her diet.
In addition, the doctor also recommended that Sister Zhang attend a nutrition knowledge lecture to enhance her understanding of the nutrients in food.
With the passage of time, Sister Zhang's symptoms have improved significantly.
She began to pay more attention to her diet and encouraged her friends and customers to pay attention to her nutritional intake.
Through Sister Zhang's experience, this story shows us the importance of nutrition knowledge, especially for the elderly, even years of eating habits may need to be adjusted to adapt to the needs of the body's changes.
The article concludes with the question: Given the complexity of modern dietary diversity and nutrient intake, how can we more effectively increase awareness and understanding of the importance of key nutrients through communities and healthcare systems?
A detailed analysis of this will first require public health policies to increase access to nutrition education, especially among older people.
The government can do this through health promotion campaigns, setting up informative public advertisements, and holding regular health and nutrition talks at community centres.
The healthcare system should strengthen the assessment and guidance of patients' dietary habits, especially the inclusion of nutritional counseling services in routine physical examinations.
In addition, mobile apps or online platforms can be developed to provide personalized nutrition advice and diet plans to help people better understand and apply nutrition knowledge to ensure that they are getting all the essential nutrients.
These measures will help the public build healthier and more balanced eating habits, which will improve overall health.
