yes sir it is bad for your heart. High cholesterol is a major risk factor for coronary heart disease, a cause of heart attacks, and reducing blood lipid levels lowers the cardiovascular risk.4
High levels of LDL lead to a build-up of cholesterol in the arteries, whereas HDL carries cholesterol to the liver for removal from the body.2 A build-up of cholesterol is part of the process that narrows arteries, called atherosclerosis, in which plaques form and cause restriction of blood flow.2
High cholesterol levels are a result of modifiable and non-modifiable risk factors. Two major risk factors, diet
and exercise, are highly modifiable, meaning that something can be done to change these risk factors and reduce the likelihood of having high cholesterol.2
Limiting intake of fat in the diet helps manage cholesterol levels. In particular, it is helpful to limit foods that contain:2
Food sources of cholesterol
Meat, cheese and egg yolks are sources of cholesterol.
Cholesterol (from animal foods, such as egg yolks, meat and cheese)
Saturated fat (found in some meats, dairy products, chocolate, baked goods, and deep-fried and processed foods)
Trans fat (found in some fried and processed foods).
Being overweight or obese can also lead to higher blood LDL levels, with regular exercise helpful in managing this risk factor.2
The primary causes of high cholesterol are genetic - very high LDL levels are found in the inherited condition familial hypercholesterolemia.5
Abnormal cholesterol levels may also be secondary to the following:5,6
Liver or kidney disease
Polycystic ovary syndrome
Pregnancy and other conditions that increase levels of female hormones
Underactive thyroid gland.
Drugs that increase LDL cholesterol and decrease HDL cholesterol (progestins, anabolic steroids and corticosteroids).
