A man was scared when 2 liters of oil were drawn from his blood during a physical examination

Recently, Mr. Wang from Hankou had a very profound experience (#2 liters of oily blood were extracted from a man's blood during a physical examination#). When the doctor was doing a preoperative examination for him, he needed to do plasma exchange. After more than 3 hours, the doctor actually separated 2 liters of oily blood from Mr. Wang's blood. After seeing the "collection" in his body, Mr. Wang even said "It's so scary to see it", and he was actually scared by his own "blood".

It is understood that Mr. Wang's eating habits are very unhealthy. He is usually very busy and thinks: I am already so fat, so I can just eat whatever I want. Basically, he eats fried chicken, hamburgers, and big fish and meat, which causes his body to store a lot of "fat".

In fact, there are many people in our lives who have similar living habits as Mr. Wang, and some of them cannot live without meat, and feel uncomfortable without meat for a day. After reading this news, these people are probably worried about their blood lipids.

For people who like to eat meat but are worried about their blood lipids, this article will talk about how to eat meat so that it is both delicious and healthy. Let’s learn it together!

1. What kind of meat is recommended?

If you want to keep your blood lipid levels healthier, you need to pay special attention to limiting the intake of saturated fatty acids and cholesterol in your diet. Since most meats contain both saturated fatty acids and cholesterol, you really need to be careful when choosing the type of meat you eat.

According to the recommendations in the "Primary Health Management Standards for Dyslipidemia", patients with dyslipidemia should reduce and avoid eating animal offal, fish roe, crab roe, shrimp roe, meat with skin, fatty meat, and processed cooked meat products (sausages, meat floss, and sausages), because these foods are high in saturated fatty acids and cholesterol, which are not conducive to blood lipid control. They should choose more lean meat, sea cucumbers, fish, shrimp, and other foods with lower saturated fatty acid and cholesterol content [1]. Poultry meat is also a good choice.

Among them, it is especially recommended that you eat more fish.

Evidence-based medicine shows that fish and fish oil are rich in EPA and DHA, which belong to the n-3 series of unsaturated fatty acids. They can reduce the risk of cardiovascular disease, have a strong effect in lowering TG (triglycerides), increasing HDL-C (high-density lipoprotein cholesterol/good cholesterol), and can prevent coronary heart disease. [2]

So, which fish do you recommend eating?

On January 18, 2017, the U.S. Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) released their final recommendations for fish consumption, recommending eating 227 to 340 grams of low-mercury fish per week. For the recommended fish, see the following chart:

2. How much is appropriate to eat?

According to the recommendations of the Chinese Dietary Guidelines, livestock and poultry meat and aquatic products can be consumed in amounts of 40 to 75 grams each. [3]

If you do not have many opportunities to eat seafood and cannot eat it every day, you can also plan to eat fish twice a week or more, 150-200 grams each time. [2] Generally, a piece of fish the size of the palm of our hand is about 80-100 grams.

For vegans who do not eat fish, they can choose to eat nuts or flaxseed oil, or they can supplement with α-linolenic acid (n-3 series). If that doesn't work, they can supplement with fish oil preparations.

3. Recommended cooking methods

Lighter cooking methods are recommended, such as steaming, stewing, cold dressing, stir-frying, etc. Frying, baking, smoking, etc. are not recommended.

The "Basic Health Management Standards for Dyslipidemia" mentions reducing and avoiding fried meat, not only because fried foods are high in calories and fat, but also because high-temperature frying will produce trans fatty acids.

Metabolic and population studies have shown that excessive intake of trans fatty acids not only increases LDL-C (low-density lipoprotein cholesterol/bad cholesterol), but also reduces HDL-C (good cholesterol), which not only increases the risk of dyslipidemia, but also easily induces atherosclerosis and increases the risk of coronary heart disease. [2]

To reduce the intake of trans fatty acids, in addition to avoiding deep-frying, you should also eat less crispy chips, biscuits, and creamy cakes, because their ingredients generally contain shortening, margarine, artificial butter, non-dairy creamer, etc., which means they contain trans fatty acids.

Summary: Meat lovers should pay attention to their blood lipids. Learning how to enjoy delicious food in a healthy way is the key. In addition, it is also recommended to quit smoking, limit alcohol consumption, and exercise regularly, which will greatly help lower blood lipids.
