Good heart health is like a building block: It’s cumulative.

The earlier you try to start making healthy lifestyle choices, the better off you can be as you get older. Think about making small changes now that will lead to big changes years later. It’s like a train altering its course slightly, which leads to a big difference in its final destination.

This is particularly true when it comes to high cholesterol.

Cholesterol is a fatty substance your liver makes. It’s also found in certain foods. Your body needs some cholesterol to function properly. But having too much of the bad type of cholesterol — LDL — puts you at risk for having a heart attack or stroke.

Cholesterol in your bloodstream can build up in blood vessel walls, causing blockages that can lead to:

  • reduced blood flow to the heart and increased risk for heart attack
  • decreased blood flow to the brain and increased risk for stroke

According to the Centers for Disease Control and Prevention (CDC), having high cholesterol raises your risk for heart disease.

Your total cholesterol level is the overall amount of cholesterol found in your blood. It consists of:

  • low-density lipoproteins (LDL)
  • high-density lipoproteins (HDL)
  • triglycerides

LDL is also called “bad” cholesterol because it blocks your blood vessels and increases your risk for heart disease. HDL is considered “good” cholesterol because it helps protect you from heart disease. The higher your HDL, the better.

Finally, total cholesterol includes a triglycerides count. These are another type of fat that can build up in the body and are considered the “building blocks” of cholesterol.

High levels of triglycerides and low levels of HDL raise your risk for heart disease.

The American Heart Association recommends that all adults have their cholesterol checked every 4 to 6 years, starting at age 20, which is when cholesterol levels can start to rise.

As we age, cholesterol levels tend to climb. Men are generally at a higher risk than women for higher cholesterol. However, a woman’s risk goes up after she enters menopause.

For those with high cholesterol and other cardiac risk factors, such as diabetes, more frequent testing is recommended.

Cholesterol chart for adults

According to the 2018 guidelines on the management of blood cholesterol published in the Journal of the American College of Cardiology (JACC), these are the acceptable, borderline, and high measurements for adults.

All values are in mg/dL (milligrams per deciliter) and are based on fasting measurements.

Total cholesterolHDL cholesterolLDL cholesterolTriglycerides
GoodLess than 200 (but the lower the better)Ideal is 60 or higher; 40 or higher for men and 50 or higher for women is acceptableLess than 100; below 70 if coronary artery disease is presentLess than 149; ideal is <100
Borderline to moderately elevated200–239n/a130–159150–199
High240 or higher60 or higher
160 or higher; 190 considered very high
200 or higher; 500 considered very high
Lown/aless than 40n/an/a

Children who are physically active, have a healthy diet, are not overweight, and don’t have a family history of high cholesterol are at a lower risk for having high cholesterol.

Current guidelines recommend that all children have their cholesterol checked between ages 9 and 11, and then again between ages 17 and 21.

Children with more risk factors, such as having diabetes, obesity, or a family history of high cholesterol, should be checked between ages 2 and 8, and again between ages 12 and 16.

Cholesterol chart for children

According to the JACC, the following are the recommended cholesterol levels for children:

All values are in mg/dL:

The good news is that lifestyle changes are reasonably effective in helping you to reduce cholesterol levels. They’re also fairly straightforward and can be done at any age.

Changes include:

Exercise

Physical activity can help you lose weight and boost your HDL cholesterol. Aim for 30 to 60 minutes a day of moderate cardiovascular exercise, such as biking, jogging, swimming, and dancing, at least 5 times a week.

Eat more fiber

Try to add more fiber to your diet, such as replacing white bread and pasta with whole grains.

Eat healthy fats

Healthy fats include:

These are all fats that won’t raise your LDL levels.

Limit your cholesterol intake

Reduce the amount of high-saturated fatty foods like:

Quit smoking

Smoking decreases HDL cholesterol. If you smoke, quitting can help you better manage your cholesterol levels.

It’s important to remember that everyone is different.

Family history and whether or not you have other conditions, such as diabetes or obesity, play a role in your individual risk.

Talk to your healthcare provider about your cholesterol levels and ask what they think your numbers should be.

“The key is to have normal cholesterol levels throughout your lifetime.

“One misconception is that people can have poorly controlled cholesterol for years and then decide to take action. By then the plaque could already have built up,” says Dr. Eugenia Gianos, director of Cardiovascular Prevention for Northwell Health in New York.

Limit your alcohol intake

The American Heart Association recommends drinking alcohol in moderation, which means, on average, no more than two drinks per day for men and no more than one drink per day for women.

Drinking too much alcohol can raise levels of triglyceride fats in the bloodstream and lead to conditions, such as:

Lose Weight

Losing excess body weight can help to lower your cholesterol levels.

To lose weight, here are a few tips.

  • Try to make healthy dietary changes and focus on portion control.
  • Try to choose lean proteins, whole grains, fruits, and vegetables.
  • Try to limit unhealthy fats, processed foods, and sugary snacks.
  • Try to add more physical activity to your weekly routine to increase your calorie burn so the number of calories you’re consuming is less than the number you’re burning.
