Nowadays, many people have high blood lipids, and the condition is becoming more common among younger individuals. Hyperlipidemia is a type of dyslipidemia, a disorder caused by abnormal fat metabolism or transport, which leads to one or more lipids in the plasma being higher than normal levels. A diet high in saturated fat and cholesterol is one of the causes of hyperlipidemia, so people with this condition should generally control their intake of fats and cholesterol. Everyone knows that egg yolks contain cholesterol, but if a physical exam reveals high blood lipids, can you still enjoy eggs properly?
First, let's understand the recommended daily intake of cholesterol. Authoritative organizations such as the World Health Organization, the American Heart Association, and the Chinese Nutrition Society all recommend that adults consume no more than 300 milligrams of cholesterol per day. China's Ministry of Health - Cardiovascular Disease Prevention and Control Center, on the other hand, suggests that individuals with hyperlipidemia should limit their cholesterol intake to less than 200 milligrams per day.
Second, let's learn more about cholesterol. Many of us are afraid of cholesterol, especially middle-aged and older people, because excessive consumption can raise blood lipid levels, which is a valid concern. However, cholesterol is also an essential nutrient for the human body, and its functions include the following:
(1) Synthesis of Vitamin D: 7-dehydrocholesterol in our skin synthesizes vitamin D under the influence of ultraviolet sunlight from the sun, and vitamin D promotes calcium absorption, which is beneficial for bone health.
(2) Formation of Cell Membranes: The structure of every cell in the human body relies on cholesterol, especially in our brains, which is the area with the highest cholesterol content.
(3) Formation of Bile Acids: Bile acids are an important component of bile, and our fat digestion is inseparable from bile. Because bile can emulsify fats and aid in digestion.
To meet its own needs, the human body synthesizes over 1000 milligrams of cholesterol every day, of which 30% needs to be supplemented from food. The body only experiences cholesterol deposition on blood vessel walls when there is a disorder in cholesterol metabolism, which in turn leads to cardiovascular diseases.
Finally, let's look at eggs. Although one egg (about 50g) contains 292.5 milligrams of cholesterol, the betaine and lutein in eggs contribute to reducing the incidence of heart disease. Moreover, the lecithin in eggs is a powerful emulsifier that can lower cholesterol in peripheral blood vessels and has a good lipid-lowering effect.
Therefore, it is recommended that individuals with hyperlipidemia control their cholesterol intake to within 200 milligrams per day, and it is advisable to eat one egg per day or every other day. It is best to choose boiled eggs, steamed egg custard, etc.
In conclusion, we should look at issues from two perspectives. People with hyperlipidemia can eat eggs in moderation, one a day or every other day is fine. It is best not to choose fried methods to avoid consuming more oil. Additionally, it helps to eat more foods rich in dietary fiber, control body weight, increase regular physical activity, quit smoking, limit salt, and lower blood pressure.
