High cholesterol is an extremely common concern around the world. Chances are, you have read about cholesterol and know that it is associated with heart disease or other diseases. Maybe a family member or friend has talked to you about their cholesterol levels.
Now, cholesterol is not all bad. The simple truth is that cholesterol is necessary for our bodies. They make cholesterol to process food and store energy. Cholesterol helps our bodies by transporting fats to different areas so we can use them for energy.
Think of cholesterol molecules like cars on the freeway, pushing through the arteries to get to their destination. When there are lots of cars, then there is a lot of congestion, and the natural flow of traffic slows down. Similarly in our arteries, when cholesterol molecules build up in the arteries, then blood flow is impacted.
Cholesterol is necessary for our bodies, but problems occur when the cholesterol levels in our bodies become unbalanced. Large amounts of LDL cholesterol (“bad” cholesterol) can contribute to problems like heart disease or stroke. Maintaining an appropriate balance of cholesterol can help reduce the risk of heart disease and ensure your body is using energy efficiently.
Factors like your diet, exercise habits, and genetics play an important role in determining your cholesterol balance, which will be discussed in this article.
Your diet has the biggest impact on your cholesterol levels.
Foods that are rich in saturated and unsaturated fats can raise your cholesterol. To limit intake of high-cholesterol foods, cut back on:
- Fried foods
- Red meat
- Animal-based cooking oils and fats, like lard
Foods filled with fiber, such as leafy green vegetables, whole-grain breads, and fruits, are known to lower your cholesterol levels. Fiber helps to remove cholesterol from the body.
Healthy Food Can Still Be High in Cholesterol
Some foods such as coconut oil may seem healthy, but they actually cause high cholesterol.
Limiting cholesterol-rich foods and eating more fiber-rich foods is a great way to reduce your cholesterol naturally.
You can also increase your consumption of certain foods to help improve your HDL cholesterol (“good” cholesterol) levels. Foods such as fish and avocados are good options for boosting healthy cholesterol.
Living an active and healthy life can help your cholesterol levels, including:
- Ensuring that you walk or exercise at least 30 minutes five times per week
- Maintaining a good sleep schedule
- Quitting smoking
Cigarettes are known to cause heart disease and can make high cholesterol levels even more problematic in the body.
Genetics plays a major role in controlling cholesterol levels.
We know that specific genetic disorders like familial hypercholesterolemia can cause extremely elevated cholesterol levels.
If you and several of your family members have extremely high levels of cholesterol, then you may want to have a doctor evaluate your genetic history. Some studies also have shown different cholesterol levels among White, Black, and South Asian populations.
Further research is needed to understand if specific genes might control cholesterol levels.
Some disorders—like coronary artery disease, atherosclerosis, diabetes, and hypertension—are commonly connected to high cholesterol levels.
Elevated cholesterol levels can make many of these other conditions worse, so it is even more important to get the levels under control. Oftentimes, doctors prescribe medications called statins to treat high cholesterol levels. The statin medications work alongside other medications to help reduce cholesterol levels.
