Lao Wang is 64 years old this year, he was a teacher before retirement, he has a cheerful and optimistic personality, he has been a teacher for decades, he is deeply loved by students, and his life after retirement is leisurely, but he is not idle, but he is happy to do what he likes, such as going to the park every day for a walk, playing chess, chatting with old friends, Lao Wang has always paid attention to health, I heard that eating pork liver is good for the body, so he developed the habit of eating pork liver twice a week.
A year later, Wang went to the hospital for a routine physical examination as usual, and after the physical examination report came out, Wang was surprised to find that his physical indicators had changed significantly: blood viscosity increased, cholesterol and triglyceride levels were high, and liver function-related indicators were also abnormal, which made Wang, who had always been full of confidence, feel very confused and uneasy.
Lao Wang was a little puzzled, he usually felt very well, how could these problems occur? He decided to consult a doctor, who carefully read his physical examination report and asked, "Lao Wang, do you usually have any eating habits?" Do you often eat some high-fat, high-cholesterol foods? ＂
Lao Wang thought for a while and said: "I will eat pork liver twice a week, about four or five taels each time, because I heard that pork liver has high nutritional value and is good for the body, so I have been insisting on eating it, is there a problem with this?" ＂
The doctor nodded and patiently explained: "Pork liver is indeed rich in a variety of nutrients, such as high-quality protein, iron, zinc, vitamin A, etc., and proper consumption is indeed beneficial to the body, but the cholesterol content of pork liver is also very high, containing more than 300 mg per 100 grams, and the mainland's "Dietary Guidelines for Chinese Residents" suggests that adults should control the daily intake of cholesterol from food below 300 mg, and if you eat pork liver twice a week, four or five taels each time, then the amount of cholesterol ingested per week may have exceeded 1000 mg. Far exceeding the recommended value, long-term large intake, will increase the risk of atherosclerosis, coronary heart disease and other chronic diseases. ＂
Lao Wang suddenly realized: "No wonder my cholesterol level will rise, it turns out that I eat too much pork liver, so what should I do now?" Are you going to stop eating pork liver altogether? ＂
The doctor smiled and shook his head: "Don't go to extremes, just do it in moderation, I suggest that you reduce the number of times you eat pork liver to 1 time a week, and control the amount of each time to about 2 taels, and at the same time pay attention to a balanced diet, eat more vegetables and fruits, eat less animal offal, fatty meat and other high-cholesterol foods, exercise properly, maintain a healthy lifestyle, I believe that through a period of dietary conditioning and lifestyle improvement, your physical indicators can return to normal." ＂
Lao Wang was relieved after hearing this, and nodded again and again to show that he followed the doctor's instructions, and at the same time he secretly set a goal for himself: in the future, he must learn to maintain health scientifically and be a healthy old man in the new era.
This story has given us a lot of inspiration, with the improvement of living standards, more and more people have begun to pay attention to health care, but on the road to health, we will inevitably encounter some "blind spots" and "misunderstandings", many people blindly pursue the so-called "food supplements", "supplements", but they do not know that any food is a "double-edged sword", excessive consumption, often do more harm than good.
Take pork liver as an example, although it is rich in iron, protein and a variety of vitamins, is recognized as a "treasure trove of nutrition", but also contains a lot of cholesterol and saturated fatty acids, studies have shown that every 100 grams of pork liver contains up to 424 mg of cholesterol, almost twice the recommended daily intake for adults, long-term consumption of large quantities, will inevitably bury hidden dangers to the cardiovascular system and liver health.
Of course, we can not "talk about liver discoloration", completely abandon the pork liver, which is a highly nutritious food, and eat pork liver appropriately, which can provide the body with high-quality protein, heme iron, B vitamins and other nutrients, which are good for preventing anemia, promoting growth and development, and enhancing immunity.
Generally speaking, adults eat pork liver 1-2 times a week, about 20-100 grams each time, should not be excessive, the elderly, children, pregnant women and other special populations, due to the difference in the body's metabolic capacity and nutritional needs, the amount of consumption should be more cautious, in addition to people with hypertension, hyperlipidemia, liver disease and other underlying diseases, it is recommended to follow the doctor's instructions, if necessary, you can consider avoiding food.
A balanced diet is the key to a healthy regimen, and in addition to pork liver, there are many ingredients in the daily diet that should not be underestimated, such as deep-sea fish, which not only provides high-quality protein, but is also rich in unsaturated fatty acids such as Omega-3, which is beneficial to maintaining cardiovascular health; Fresh fruits and vegetables are known to be low in calories, high in fibre, rich in vitamins and antioxidants, and are an important part of a balanced diet. Legumes and whole grains are known to be high in protein, low in fat, and rich in B vitamins.
