Cholesterol is a waxy substance found in the cells of the body. It is a type of lipid (fat) essential for the proper functioning of the body. Your body uses cholesterol to create cell membranes, hormones, and vitamin D.

Cholesterol is derived from two sources: it is produced by the liver and can be obtained from various animal-based foods, such as meat, poultry, and dairy products. Some of these foods contain high levels of saturated and trans fats, which cause your liver to make more cholesterol than it otherwise would. This added production increases normal cholesterol levels to one that is unhealthy.

Types of cholesterol

Cholesterol travels through the bloodstream on proteins called lipoproteins (particles in the blood made up of lipids and proteins). There are two main types of lipoproteins: High-density lipoprotein (HDL) and Low-density lipoprotein (LDL).

HDL is known as ‘good’ cholesterol because it helps remove excess cholesterol from the bloodstream and carries it back to the liver, where it is either broken down or passed out of the body as a waste product.

What is LDL cholesterol?

LDL, also referred to as ‘bad’ cholesterol, as the name suggests is bad for the body. It is a combination of fat and protein that transports cholesterol from the liver to other body parts, including the arteries.

High cholesterol has no symptoms. The only way to detect it is through a blood test called a ‘lipid profile’. To determine your total cholesterol and for accurate results, ensure you follow the given pointers before the test,

Avoid any strenuous activity
Fast for at least 9-12 hours
Inform the doctor about any medical conditions or medications

Healthcare providers use the following categories to describe your LDL cholesterol level:

Normal: Below 100 mg/dL
Near-optimal: 100 – 129 mg/dL
Borderline high: 130 – 159 mg/dL
High: 160 – 189 mg/dL
Very high: 190 mg/dL or higher

Men are at a higher risk of high cholesterol than women. However, the menopause phase can increase the risk of high cholesterol in women. The risk of high cholesterol increases for men between the ages of 45-65 and women between 55-65.

Effects of high LDL cholesterol

The consequences of high LDL cholesterol levels cannot be downplayed. It can lead to a number of negative consequences, including:

Cardiovascular disease: When LDL cholesterol is deposited in the walls of the arteries, the plaque build-up in them causes the arteries to narrow and become less flexible, resulting in a condition known as atherosclerosis. High amounts of bad cholesterol can clog up a critical path, restricting the blood flow to the heart, brain, and the rest of the body, which can increase the risk of heart disease, stroke, and other cardiovascular complications;
Peripheral Artery Damage (PAD) is a condition in which the arteries in the legs become narrow or blocked, causing leg pain, cramping, and difficulty walking;
In addition, coronary heart disease, accompanied by other issues like smoking, high blood pressure (hypertension), or diabetes, puts you at a higher risk of severe health problems.

What causes high LDL cholesterol?

Many factors can be linked to heart problems or strokes. These include:

Poor diet: An unhealthy diet high in saturated and trans fats can increase cholesterol levels in the body.
Lack of physical activity: A sedentary and inactive lifestyle can contribute to high cholesterol levels.
Obesity: People who are obese or overweight tend to have high LDL cholesterol levels. Obesity can cause insulin resistance, making the body less sensitive to insulin. Thus, it can lead to higher levels of triglycerides and LDL cholesterol in the body.
Smoking: A toxic chemical called acrolein, found in cigarettes, damage the blood vessel lining and increases the level of oxidative stress in the body, leading to the formation of oxidized LDL cholesterol. Oxidized LDL is more prone to stick to the artery walls, forming fatty deposits and plaques. Additionally, acrolein can stimulate the production of reactive oxygen species (ROS) and other pro-inflammatory molecules, which promotes the oxidation of LDL cholesterol.
Genetics: High cholesterol levels can run in families. Individuals may inherit the genes that cause their bodies to produce more cholesterol. Hypercholesterolemia is an inherited condition that may occur in some individuals, despite consuming healthy food daily.
Medical conditions: Certain medical conditions, such as diabetes, hyperthyroidism, and liver or kidney disease, can increase cholesterol levels.
Medications: Certain diuretics or beta-blocker medications can also increase cholesterol levels in the body.

Tips to cut your cholesterol levels

Maintaining a healthy and balanced diet is the first step to reducing your cholesterol. Take a look at the foods that can help lower your cholesterol levels.

Ban trans fats

Trans fats are a type of unsaturated fat that can increase LDL cholesterol levels in the body. Cut down on foods that include trans or saturated fats. Some of them are listed as follows:

Fried foods, such as french fries, doughnuts, fried chicken, or foods cooked in hydrogenated oils
Margarine, especially those that are solid at room temperature
Baked goods, like cakes, pastries, and muffins
Packaged snacks, like crackers, chips, and cookies, which often contain partially hydrogenated oils
Fast foods, including burgers and tacos
Red meat, such as pork chops, steak, ribs, and ground beef
Butter, ghee, lard

Scale back

Inactive individuals who are overweight are more likely to develop LDL cholesterol. Eat a balanced diet replete with whole grains, lean protein, fruits and vegetables. Be mindful of the portion sizes of the food you eat. Use small plates and avoid going back for second helpings.

Get moving

Aim for at least 30 minutes of moderate-intensity exercise most days of the week. Regular physical activity can help improve cholesterol levels. It can increase the production of enzymes that help in breaking down triglycerides and LDL cholesterol in the blood.

Go fish

Fatty fish are a rich source of omega-3 fatty acids, a type of polyunsaturated fat, which can lower LDL cholesterol. Omega-3 fatty acids comprise anti-inflammatory properties and lower triglycerides, which can help reduce LDL cholesterol levels. Some examples of fatty fish include tuna, salmon, sardines, and mackerel.

Go nuts

Consuming almonds, walnuts, peanuts, and other types of nuts can benefit your heart health. Nuts are a rich source of monounsaturated and polyunsaturated fats, which can help lower harmful cholesterol levels in the blood. They are also a good source of fiber and a powerhouse of antioxidants, which can help protect against oxidative stress and inflammation, both of which are linked to heart health.

Chill out

Following a healthy diet does not suffice. Incorporate specific lifestyle changes to cut down on your cholesterol level. Get adequate sleep of at least 7-8 hours to avoid weight gain. Practise yoga and mindfulness meditation to reduce stress.

It is essential to regularly check your cholesterol to ensure you are at a healthy level. You can determine your total cholesterol through our online Total Cholesterol Calculator.
