Cholesterol is essential to our body, all our cells contain it. Its role is to keep the flexibility and strength of our arteries. Cholesterol is a lipid carried in the blood. It is largely manufactured by the liver (about 75%), and our diet provides the rest. The carriers of cholesterol in the blood are lipoproteins. Low density lipoproteins (LDL) carry cholesterol from the liver to the cells that use it. When cholesterol is in excess, it is deposited in patches on the arterial walls and ends up clogging them. This is called bad cholesterol. High-density lipoprotein (HDL) transports cholesterol from the cells to the liver, which processes and eliminates it. It's the good cholesterol.
When we eat too much bad fats (saturated fat), the liver makes more cholesterol than necessary, while its ability to eliminate it decreases. LDL levels increase, arteries are saturated, we run the risk of arteriosclerosis.

A healthy diet helps increase good cholesterol and reduce bad
It is important to manage your daily fat intake. Choose foods that provide omega 3s, such as vegetable oils and oily fish, limit industrial products and alcohol, and engage in physical activity. It is possible to include saturated fatty acids in a balanced diet.
