High cholesterol is a very common condition experienced by 1 in 3 adults. There is good cholesterol (HDL) and bad cholesterol (LDL), and high levels of the LDL can be very dangerous to health.
What is cholesterol?
Cholesterol is a type of fat which is used to build and repair cells to make hormones. Our liver makes this cholesterol in different types, two important types of cholesterol are LDL and HDL. Low density lipoprotein cholesterol (LDL) is known as the bad cholesterol. High density lipoprotein cholesterol (HDL) is known as good cholesterol.
Cholesterol can be detected through a blood cholesterol test called a lipid profile. This measures the LDL, HDL and Triglycerides. Triglycerides are another type of fat in the blood which can contribute to risk of heart health.
High cholesterol
High cholesterol is when our LDL is high. This can lead to narrowing and hardening of the arteries, which can increase the risk of a heart attack and stroke.
Increased levels of LDL in the blood can increase the risk of heart and blood vessel disease. The excess further leads to fatty deposits called plaque in the artery walls. Thus putting you at higher risk of angina, heart attack, stroke or peripheral vascular disease.
However high levels of HDL are beneficial as it helps remove other forms of cholesterol from the blood, taking it back to the liver to be removed as waste.

Trans-fats are found in store goods, snack foods and deep fried foods.

Foods which are fried such as deep fried meats and cheese sticks are high in trans fats and in calories thus high in cholesterol. Consuming fast food frequently is linked to higher cholesterol, more belly fat, higher levels of inflammation and higher blood pressure.
Deserts such as cookies, cakes and cream are high in cholesterol and provide added calories and unhealthy sugar intake. Research has linked high intake of LDL foods to obesity, diabetes, heart disease and certain cancers.
How can I lower my cholesterol with medicines?
