The origin of cholesterol is mostly from food.

Cholesterol is a fat present in the cell membrane of the vast majority of tissues held in the body and they are transported in the plasma of the human body. The origin of cholesterol is largely from food synthesized by the liver from saturated fats, and a small portion of cholesterol is absorbed directly from food such as milk, eggs, brain, red meat, pig's heart, heart cow, animal fat, shrimp .

Characteristics of Cholesterol

Cholesterol cannot dissolve in blood when moving to cells, thanks to lipoproteins (lipoproteins are substances synthesized by the liver, dissolved in water carrying cholesterol).

Cholesterol is synthesized through 2 sources: exogenous source (an external source ), endogenous source (a source of liver, self-made cells in the body).

Science has proven that our bodies need Cholesterol to help maintain healthy cells, increase metabolism in the body, create vitamin D, create green bile, . However, we Attention should be paid to controlling the amount of cholesterol we absorb into the body because Cholesterol has two types: Good and Bad. If we let the bad cholesterol increase too high (exceeding the permitted level), it will adversely affect our health. Complications can cause blood vessel congestion or many other dangerous diseases.

Cholesterol disease is also known as excess cholesterol or high cholesterol.

When too much cholesterol in the blood is left over, they will build up into fatty deposits in the blood vessel walls and interfere with blood flow in the arteries. Then the amount of oxygen in the blood will not provide enough for the heart and thus the risk of heart attack will increase. When blood runs to the brain, it can cause a stroke.

Hypercholesterolemia (hypercholesterolemia) has no signs of manifestations of the disease, only detected when a blood test.

But fortunately, this preventive disease is not complicated. We just need to incorporate healthy eating, regular exercise and a proper lifestyle change that can help with high cholesterol.

  • High LDL Cholesterol Index, also called Cholesterol , is a type of lipoprotein that carries cholesterol in the blood, which is not beneficial because it causes excess cholesterol to enter the blood vessel walls causing atherosclerosis complications or arteriosclerosis, myocardial infarction .
