Although cholesterol is necessary for the construction of cells in the body, an increase in the level of bad cholesterol (LDL) can cause serious problems, including heart attacks. The main reasons are:
Unscientific diet: Excessive consumption of foods containing saturated fat and trans fat is the main culprit. Red meat (beef, mutton), fried foods, bakery products, and dairy products increase blood fat.
Lack of exercise: Decreased physical activity causes a decrease in the level of good cholesterol (HDL) and an increase in bad cholesterol. Walking daily can help burn fat in the blood.
Smoking and alcohol: Chemicals in tobacco damage the walls of blood vessels, which causes fat to accumulate easily. Excessive alcohol consumption increases the level of triglycerides in the blood and affects heart health.
Obesity and age: Weight gain, especially around the belly, can raise cholesterol levels. In addition, the liver’s ability to remove cholesterol decreases with age.
Genetics: Some people have high cholesterol in their blood due to genetic factors (Familial Hypercholesterolemia), even though their diet is healthy. This is due to differences in the way the liver handles cholesterol.
