"Dr. Li, I feel chest tightness and shortness of breath, I drank a little too much last night. On the first working day after the May Day holiday, a woman named Sheng Jasmine said anxiously to the doctor in the hospital office.
Sheng Jasmine, 67, is a retired librarian who has loved reading all her life and has a gentle and humorous personality.
During the vacation, she held a long-awaited party with her old classmates, but she drank too much alcohol and felt unwell when she returned home.
Jasmine's trip to the hospital not only uncovered the temporary discomfort caused by her overdose, but also examined the long-term effects of her eating habits over the years.
Because Jasmine Sheng has not consumed lard for more than 20 years, she firmly believes that this diet will keep her away from cardiovascular diseases.
However, the results were unexpected.
After the doctor's examination, he said to Sheng Jasmine: "Your blood lipids are slightly high, although they have not reached the level of severity, but it is recommended that you adjust your diet." ”
Sheng Jasmine was surprised when she heard this, because she had always thought that avoiding animal fat would keep her blood lipids at normal levels.
In fact, lard is completely excluded from Sheng Jasmine's diet, and vegetable oils, especially canola and olive oil, are mainly used.
In her understanding, these are healthier options. However, Sheng Jasmine has neglected an important principle of nutritional balance - the balanced intake of different types of fatty acids.
Dr. Li explains: "Although vegetable oils are rich in unsaturated fatty acids, which are good for heart health, moderate amounts of saturated fatty acids, such as those found in lard, are also necessary.
They are involved in many biochemical processes, including the synthesis of some hormones and the construction of cell membranes. ”
Further blood tests showed that Jasmine Sheng had low levels of HDL (high-density lipoprotein, commonly known as "good cholesterol").
"Saturated fatty acids are beneficial for maintaining healthy HDL levels, and a lack of them can lead to insufficient levels of good cholesterol. ”
Sheng Jasmine then realized that her diet may have inadvertently caused nutritional imbalance.
Past studies have shown that the relationship between saturated fatty acids and cardiovascular disease is not entirely negative, and that moderate intake is beneficial to health.
Dr. Li also shared other similar cases, such as a middle-aged man who avoided all types of animal fats for many years, and eventually found that his cell function was impaired and his immunity was reduced.
Doctors emphasize that nutritional diversity is key, and proper intake of saturated fatty acids is equally important for health.
To further illustrate this point, Dr. Li cites a large number of research data to support it. For example, a study involving 10,000 participants showed that
People who did not consume saturated fatty acids at all did not have a significantly lower risk of cardiovascular disease, but in some cases, such as when HDL was too low, the risk was slightly increased.
Jasmine Sheng thought deeply about it and decided to re-evaluate her eating habits.
She began experimenting with adding a small amount of lard to her cooking, while maintaining the use of vegetable oils, striving to achieve a balance of fatty acids.
Her story sparked a heated discussion in the circle of friends, and many people began to reflect on their eating habits.
Sheng Jasmine's change is not only an adjustment to her diet, but also a return and a new understanding of traditional food culture.
At this point, the article raises a derivative question: in modern society, how to maintain the essence of traditional food culture while pursuing healthy eating? This question is worthy of our in-depth discussion.
Modern dietary trends emphasize low fat and high fiber, but traditional food cultures encompass a wealth of dietary diversity and nutritional balance.
How to incorporate traditional wisdom into the modern diet is not only the task of nutritionists, but also the challenge of everyone who pursues a healthy life.
With proper meal planning and a modern interpretation of traditional diets, a balance of nutrition and culture can be achieved.
In practice, attention should be paid to the selection and processing of ingredients, while retaining the essence of traditional seasonings and cooking methods, so as to not only ensure the comprehensiveness of nutrition, but also enjoy the spiritual pleasure brought by food culture.
