Good fat is high-density lipoprotein cholesterol. High density lipoprotein cholesterol (HDL-C) can collect excess cholesterol from the blood and send it back to the liver and out of the body, so some people call this cholesterol "good cholesterol".
Bad fat is LDL cholesterol. Low-density lipoprotein cholesterol (LDL-C) is the leading cause of many heart diseases, such as atherosclerosis, commonly known as "bad cholesterol".

We often see many people with myocardial infarction and cerebral infarction, who ate a lot of big fish and meat the night before they fell ill, smoked and drank, the blood viscosity increased a lot after sleep, and the blood flow slowly formed a thrombus.
Terrible fats are saturated animal fats, which are found in meat, poultry, milk, butter and are a major source of bad cholesterol in the body. It can make blood become sticky and easy to form a thrombus, which increases the risk of heart and cerebral infarction. It also affects the secretion of hormones in the body and increases the risk of breast cancer and prostate cancer.

In Mediterranean countries, people like to eat olive oil, where the incidence of heart disease is very low. This is related to the fact that it contains more unsaturated fat. This kind of fat can reduce the content of bad cholesterol LDL, enhance the good cholesterol HDL beneficial to human body, also has an antioxidant effect, as well as reduce blood viscosity and prevent thrombosis.
There are also many kinds of vegetable oil, nuts, fish oil and so on. The scaly fish and marine fish have less bad fat and more good fat, while the scaleless fish, shrimp, and some shellfish have the opposite effect. That is to say, seafood cannot be generalized, some of the fat content is not high, and some of the fat content is relatively high.
In addition, smoking, alcoholism, low activity, high-calorie diet, and some genetic factors can increase bad fat in people. Therefore, people do not have to refuse to eat all fatty foods for fear of rising cholesterol levels. But when eating fat, we need to eat good fat foods such as rapeseed oil, olive oil, fish oil and many kinds of vegetables and try to avoid those harmful fats. This is the correct understanding of fat.
