"Sir, you need to watch your diet, especially eggs." Doctor Lao Li said to Zhang Wei with a frown while tapping on the medical records. At this moment, Zhang Wei was sitting in the examination room of the hospital, feeling worried. He is an advertising planner who has always lived an irregular life, and the night before he stayed up late to watch the entire European Championship football match, and was so excited that he couldn't sleep in the middle of the night. Suddenly, his heart was beating like a drum, making him feel unwell and he quickly climbed into bed to rest. The next day, he felt that something was still wrong with his body, so he came to the hospital for a comprehensive physical examination.
"Doctor Li, I had a fast heartbeat last night and came to see it today." Zhang Wei said with embarrassment. He knew in his heart that he usually ate too casually, and he liked to eat eggs. Whether it's fried eggs, boiled eggs, or tea eggs, they are his favorites.
"Mr. Zhang, judging from your blood test results, your cholesterol is a bit high, and your blood lipid level is not ideal." The doctor continued. "We're going to talk a little bit about your eating habits, especially about eggs."
Zhang Wei frowned, thinking in his heart, aren't eggs nutritious? One egg a day, the doctor stayed away from me. Could it be that there is something wrong with his egg relationship for many years? In order to understand the doubts in Happy, he decided to learn more about the subtle relationship between eggs and blood lipids.
Eggs, a common food, have been pushed to the "judgment seat" of the health community. Over the years, controversies over eggs have come and gone.
Some people say that eggs are rich in cholesterol, and consuming too much can lead to an increase in blood lipids; It is also said that eggs are a source of high-quality protein and are beneficial to the body. So, what is the truth?
First, let's take a look at the nutritional content of eggs. Eggs do contain cholesterol, about 186 mg of cholesterol per egg. It may sound like a lot, however, scientific studies have shown that dietary cholesterol has a much less impact on blood cholesterol levels than saturated fatty acids and trans fatty acids. In other words, the "culprit" affecting blood lipids may not be the eggs themselves, but other high-fat foods.
"Mr. Zhang, the eggs themselves are not terrible, the problem is your matching diet." Doctor Lao Li explained. "For example, when you choose a bacon omelette for breakfast instead of a simple boiled egg, saturated fat and salt are the main culprits in the elevated blood lipids."
In order to further understand the relationship between eggs and blood lipids, Zhang Wei decided to look through a series of related studies.
Surprisingly, several studies in recent years have shown that moderate intake of eggs does not significantly increase the risk of cardiovascular disease, but may instead help raise levels of high-density lipoprotein (HDL, the "good" cholesterol).
A study published in the United States Journal of Clinical Nutrition, in which scientists followed 21,000 participants over a 20-year period, found no significant association between daily egg intake and the incidence of heart disease or stroke. Conversely, in a healthy diet, eggs also provide high-quality protein and essential nutrients such as vitamin D, lutein, and choline, which play a positive role in heart health.
"However," added Dr. Li, "everyone's situation is different, and eating habits should also be different from person to person." For patients who already have cardiovascular disease or diabetes, it is still necessary to control egg intake. ”
Although the relationship between eggs and blood lipids is not as terrible as imagined, Zhang Wei still learned an important lesson: eating a balanced diet varies from person to person.
Everyone's body is sensitive to cholesterol differently, and some people are naturally sensitive to cholesterol, and even small amounts of cholesterol can cause blood lipids to rise. Therefore, it is important to know your own physical condition and family medical history.
"Mr. Zhang, you need to know your body," Dr. Li advised. "Some people are very sensitive to the cholesterol in eggs and need to be extra careful. But for most people, it's okay to eat eggs in moderation, and the key is to eat a balanced diet. ”
On the advice of his doctor, Zhang Wei decided to re-examine his eating habits. Reducing processed meat, increasing the intake of fresh fruits and vegetables, controlling salt and sugar intake, and eating high-quality proteins such as fish, legumes and nuts in moderation are all important steps to maintain good health.
In order to better understand the relationship between eggs and blood lipids, Dr. Li shared several real-life cases with Zhang Wei.
Dear readers, the author's income is so meager that he had to include a short 5-second ad in the text, and you can read the full text for free by watching it. I know it might be a little intimidating, but it does help me increase my income and keep writing. Your understanding is my biggest motivation, and I will try to bring more quality content!
Case 1: Xiao Wang, 30 years old, IT engineer, usually busy with work, often rely on fast food and supper to "survive". During the physical examination, the blood lipids were found to be high. After the guidance of the dietitian, he reduced the greasy fast food, maintained one egg a day, and rechecked it after half a year, and his blood lipid level improved significantly.
Case 2: Aunt Li, 55 years old, has a wide range of hobbies after retirement, especially cooking. For her health, she boiled eggs, scrambled eggs, and stewed frangipani every day. Later, the body test showed that the cholesterol was exceeded. On the advice of her doctor, she controlled her egg intake and increased her exercise at the same time, gradually recovering her health.
After digging deeper, Zhang Wei realized that the secret behind eggs is not just cholesterol. Eggs are an excellent source of many nutrients, including lutein and zeaxanthin, which are beneficial for eye health, and choline, which plays an important role in brain development and nerve function.
In addition, the protein in eggs is a good source of essential amino acids, which are essential for muscle growth and tissue repair.
These benefits make eggs an indispensable part of the diet, and the key is how they are consumed scientifically.
After some research and reflection, Zhang Wei decided not only to control his diet, but also to keep exercising. He started jogging every morning, replanning his diet and maintaining a good routine. Eggs are still a regular at his table, but he has learned to pair them with other foods to achieve nutritional balance.
Just when Zhang Wei was satisfied with his new healthy life, he suddenly thought of a question: In addition to eggs, what other foods have an effect on blood lipids, but we often ignore them?
The answer to this question may be more complicated than you think. The effect of diet on blood lipids depends on several factors, including total calorie intake, the type and combination of foods, and the genetic and metabolic profiles of the individual.
For example, saturated fats and trans fatty acids are important factors in elevated blood lipids and are often hidden in processed foods, fried foods, and high-fat meats. In addition, excessive sugar intake can also lead to dyslipidemia because the body converts excess sugar into fat storage.
Therefore, scientific eating is not just about focusing on one food, but also about taking into account the whole dietary pattern. By increasing dietary fiber, consuming enough fruits and vegetables and high-quality protein, drinking water in moderation and exercising regularly, people can better manage their blood lipid levels and maintain cardiovascular health.
Finally, Zhang Wei realized that health is not an overnight achievement, but a long-term adherence to a lifestyle. He decided to share what he learned with his friends, hoping that everyone could live a healthy and happy life.
