Good fats, bad fats and heart diseases

Read the doctor's analysis below to find out the truth about "eating fat increases blood fat"!


  • Cholesterol is not entirely harmful. It includes part of the essential fat that the cells in our body need.
  • Cholesterol can be made in the liver or obtained from food.
  • Cholesterol is transported in the blood by a transport medium, which is a lipoprotein.
  • HDL is known as "good cholesterol." The reduced amount of HDL cholesterol can be caused by smoking, being overweight, obese. Therefore, to increase HDL cholesterol, it is necessary to quit smoking, maintain a reasonable weight, increase physical exercise
  • LDL is the "bad cholesterol" - a factor that causes atherosclerosis, which is the cause of life-threatening diseases such as heart attack or stroke. LDL cholesterol can increase due to factors related to diet, bad habits such as smoking, passive, or related diseases such as hypertension, diabetes


1. Does eating fat cause hyperlipidemia?

The food that we eat is just the ingredients. The liver is responsible for taking these materials to convert them into an energy source for the body in the body.

The liver is also the place to take materials and synthesize them into "blood fats," namely cholesterol, triglycerides (and some other substances).

If you don't eat fat, the fat goes straight into the blood, causing blood fat.

2. Why do some people eat almost no fat, are abstinent or vegetarian, but go to the doctor, their blood fat is still high?

Some people have a unique "body," with the same amount of ingredients from food intake, and their liver tends to synthesize blood fat components such as cholesterol more than others.

The liver also tends to increase the synthesis of lousy fat more than usual if you are overweight or obese, do not exercise, smoke, or have certain medical conditions.

3. If the body causes the fat in the blood, where do you need to limit your diet?

Not true; diet still plays a part in controlling blood fat in particular and the risk of atherosclerosis in general.

Eating too many calories causes overweight and obesity, which is also a cardiovascular risk factor.

A healthy and balanced diet and other measures such as exercise and balanced mental life all contribute to reducing blood fat to the best extent possible.

4. If you want to prevent atherosclerosis and cardiovascular disease, what should you avoid?

The first thing you must remember to avoid is fast food such as french fries, fried chicken, pizza, ultra-processed foods such as sausages, cheese, snack confectionery, chocolate, instant noodles, and sugary drinks such as soft drinks, milk tea.

These are foods that have been shown to increase the risk of atherosclerosis and cardiovascular disease.


  • Saturated fat (found in red meat, cheese, dairy products) increases total cholesterol and LDL-cholesterol (i.e., bad cholesterol) in the blood, which are important cardiovascular risk factors.
  • Trans-fat (found in fried and baked foods) increases total cholesterol and LDL cholesterol and lowers good cholesterol (HDL-cholesterol).
  • Changing the type of fat in your diet (i.e., replacing saturated fat with unsaturated fat) helps reduce the risk of cardiovascular disease. Unsaturated fats are found in olive oil, fruit seeds, tree nuts, and fish oils.
  • Foods that are naturally rich in cholesterol (eggs, clams, oysters, snails, mussels, and organs) raise blood cholesterol less than eating foods containing saturated fat.
