Zheng Junhao, an attending physician in the Department of Family Medicine, Linsen Chinese Medicine Kunming Campus, Taipei United Hospital, said that cholesterol is actually one of the essential nutrients for the human body. Besides providing energy, it is also an important raw material for hormones, enzymes and cholic acid in the body. It is also an important component for synthesizing vitamin D, cell membrane, repairing blood vessel wall and brain. Without cholesterol, people can't live at all.
What's wrong with low-density cholesterol? The transport of cholesterol in the human body depends on "lipoproteins", which have various sizes. HDL is a kind of high-density lipoprotein, which is responsible for transporting cholesterol in blood back to the liver. Low density lipoprotein is a kind of low density lipoprotein, which transports cholesterol out of the liver. It is transported to various tissues through blood circulation. Zheng pointed out that high density and low density refer to protein, not cholesterol, and protein acts as a truck for transporting cholesterol. The number of "trucks" depends on the transportation volume of "goods", not because these "protein" lead to high cholesterol.
"Therefore, the values of HDL and LDL in the health examination report reflect the transport of cholesterol in the body," Zheng Junhao explained. Low-density lipoprotein is branded as "bad cholesterol" because many large-scale studies show that too high low-density lipoprotein will greatly increase the risk of cardiovascular diseases such as stroke and myocardial infarction, while high-density lipoprotein can reduce the risk, so there are good and bad opinions.
"However, the level of cholesterol is related to many reasons, such as personal physique, diet, exercise, stress, hereditary hypercholesterolemia, endocrine diseases, etc." Zheng Junhao said, "After analysis and evaluation, doctors will put forward different suggestions according to different situations of each person. 」
Can you only eat fruits and vegetables with high cholesterol? Zheng Junhao pointed out that the average daily cholesterol metabolism of an adult is about 1000 mg, while 70%-80% of cholesterol in the human body is made by the liver, and the proportion of daily dietary intake is only 20%-30%. Therefore, as long as it is not excessive intake of cholesterol, the human body can adjust itself. If the intake is insufficient, it will force the body to increase its own production.
Then, the physical examination report showed that the cholesterol was too high. How can I adjust my diet? "Dietary advice is still the old saying, a balanced diet, whole grains, beans, nuts, milk eggs, fish, fruits and vegetables, etc." Zheng Junhao reminded us to avoid eating too much starch (rice, noodles, bread, sweet potatoes, etc.). ) and sugar, and avoid excessive consumption of fruits with high sweetness.
Zheng Junhao reminded that any nutrient needs proper amount, too much is harmful to health, and so is cholesterol. "Once again, keep a balanced diet, have a good life and rest, and don't take drugs or health products of unknown origin. If you have any questions, you can consult your family doctor, who will give you the correct information. 」
