Cholesterol: Sure-Fire Ways to Lower Cholesterol

According to the World Health Organization, more than one in three people worldwide suffer from high cholesterol. Medications such as statins can protect you from heart problems caused by high cholesterol levels. But the right diet – that is, a low cholesterol diet – and an appropriate exercise routine can also help promote a normal cholesterol level.

For a long time, eggs were demonized because of their high cholesterol content. But not all cholesterol is alike. In medicine, we differentiate between healthy HDL cholesterol and unhealthy LDL cholesterol. And eggs are bursting with healthy HDL cholesterol, which can even protect you from cardiovascular disease.

Find out what cholesterol does for your body and why LDL cholesterol can be so harmful to your health. Let us inform you of ways to lower cholesterol – be it through a low cholesterol diet or exercise – and generally how to maintain a normal cholesterol level.

What Is Cholesterol?

Cholesterol is a lipophilic substance produced in the liver. This blood fat stabilizes our cell membranes and helps with digesting fat. The body produces crucial hormones such as estrogen, cortisol, and vitamin D from cholesterol. We also consume cholesterol through our diet – the more cholesterol we consume, the less cholesterol the liver produces.^{[1, 2]}

LDL Versus HDL Cholesterol: What’s the Difference?

Cholesterol does not flow freely through the body; it is found in two special proteins: HDL and LDL proteins. While HDL proteins absorb cholesterol from the body cells and transport it to the liver, LDL proteins incorporate cholesterol into the cell membranes. High levels of LDL cholesterol cause health problems such as high blood pressure and other cardiovascular diseases.^[1]

Did you know that 75 percent of the total cholesterol in our body is tied to LDL proteins?^[3]

What Happens if Your LDL Is Too High?

The ratio of LDL and HDL cholesterol is highly relevant for your health – the concentration of LDL cholesterol should not be higher than the HDL cholesterol!

If the proportion of LDL cholesterol in your total cholesterol level is too high, and that of HDL cholesterol is too low, more and more proteins are deposited in the cell membranes. The LDL cholesterol takes them there, but the HDL cholesterol cannot transport them away fast enough. Over time, your blood vessels calcify, increasing the risk of heart attacks, strokes, and blood clots. In addition, because blood flow is disrupted, vital nutrients cannot reach the body’s cells.[1, 4]

What Are Causes of High Cholesterol?

Elevated LDL and low HDL levels are detrimental to your heart health. Both lifestyle and genetic predisposition can affect your cholesterol levels.^{[1, 4]}

What Is a Normal Cholesterol Level?

What Causes Elevated Cholesterol?

There are numerous causes of high cholesterol. Cholesterol from food is probably not one of them – food has a very small effect on blood cholesterol. This means that high cholesterol foods do not actually deserve their bad reputation. But this still leaves us with the question: Why are my cholesterol levels elevated if it’s not due to my diet?

It’s true that our genetic predisposition influences how high our cholesterol levels are. Additional causes of high cholesterol include:^{[1, 2]}

• Gender and age – older men have higher average LDL levels than young women
• Menopause – LDL values increase during menopause
• Smoking and alcohol consumption
• Lack of exercise and obesity increase LDL and decrease HDL values
• Diabetes, kidney, liver, and thyroid disorders

Are There Ways to Lower Cholesterol?

There are many ways to lower cholesterol – be it through diet, exercise, or medication. No other drug is prescribed as frequently worldwide as statins – the medication used to treat high cholesterol. As soon as high cholesterol levels are detected in your body, those affected can take additional measures to lower their levels in addition to statin treatment. A number of exercises and the right low cholesterol diet can help.^[6]

Are There Any Ways to Lower Cholesterol Naturally?

A 2017 study from the journal Lipids in Health and Disease explains that aerobic exercise can help lower cholesterol in addition to statin treatment. Physical activity plays an important role in increasing HDL and reducing LDL cholesterol. Aerobic training includes sports such as running, cycling, swimming, and Nordic walking.^{[7, 8]}

How Can I Maintain a Low Cholesterol Diet?

To combat high cholesterol and achieve a normal cholesterol level, you should avoid foods that increase LDL levels. In addition to the good foods listed below, you should make sure you consume enough omega-3 fatty acids. These can support statin treatment. You should also pay attention to a diet rich in fiber, as dietary fibers can reduce LDL levels.^[1]

Low Cholesterol Diet: Choose Your Fats Wisely

If your cholesterol levels skyrocket, you should reduce the amount of saturated fats in your diet. If you have high cholesterol levels, it is best to consume a maximum of 70 grams of fat per day. Make sure that at least half of the fat comes from olive oil, walnut oil, fish, and eggs.

As far as cheese and cured meats are concerned, you can certainly opt for low-fat varieties. But be careful: Low-fat products may contain a lot of sugar to give the food more flavor. You should therefore take a look at the nutritional information on the packaging.

You should prepare meals with a low-fat content – that is, by steaming, braising, or grilling them. Although dietary cholesterol does not affect blood cholesterol, you should not consume more than 300 milligrams of cholesterol per day. Researchers are not yet in complete agreement as to whether higher amounts might influence cholesterol levels.^{[8, 24–26]}

Ways to Lower Cholesterol with Fiber

Fruits, vegetables, and wholegrain cereals not only provide us with important vitamins, but also with fiber, which can have a positive influence on cholesterol levels.

Dietary fibers are found in the cell walls of plant-based foods and are an indigestible component of food. They keep us feeling full and help to eliminate toxins. Our gut microbiome – that is, our gut bacteria – love fiber, and fiber-rich foods play a significant role in boosting our gut health.

The German Nutrition Society recommends a minimum intake of 30 milligrams of fiber per day. Fiber can also reduce the risk of colon cancer. The fiber pectin found in apples, oranges, pears, and berries and beta-glucan from oats are used to lower cholesterol. Pectin stimulates the liver to produce important bile acid from the body’s own cholesterol; as a result, LDL values decrease.^{[8, 27, 28]}

Plant-Based Foods: Do Sterols Reduce Cholesterol?

Plant-based foods contain sterols and sterols, which are similar to cholesterol in animal foods. However, they have a different effect. Sterols prevent food cholesterol from entering the bloodstream. As a result, the body uses more of its own cholesterol, which lowers LDL levels.

Sterols are found in abundance in nuts, seeds, and vegetable oils. Margarine, dairy products, and soy milk are now also enriched with sterols. However, you should not rely exclusively on these products when on a low cholesterol diet. Sterols can interfere with the absorption of vitamins, so avoid consuming too much of them.^[29]

The European Food Safety Agency recommends a maximum intake of 2.4 grams of plant sterols per day. As little as 100 grams of fruit can provide you with sufficient amounts of sterol.^[1]

Does Niacin Really Lower Cholesterol?

Like vitamin B12, niacin belongs to the group of B vitamins. Research has shown that niacin supplements can increase HDL cholesterol by up to 30 percent. However, you should only take these supplements after consulting with a doctor.

Can I Check My Cholesterol at Home?

A cholesterol test provides you with clarity about your cholesterol levels. This can be useful if you belong to one of the risk groups, such as an elderly man or a woman going through menopause, if you smoke, or are overweight. A visit to your family doctor or a home test ordered online from various health retailers can measure your total cholesterol, LDL, and HDL levels.

Additionally, triglyceride levels are often examined. Triglycerides are fat molecules that are absorbed through your diet. Elevated triglyceride levels are associated with elevated cholesterol levels and a high risk of developing cardiovascular disease.

For a conclusive result, a cholesterol test should always be performed on an empty stomach. It is best if you have not eaten for twelve hours before collecting the blood sample.^[2]
