There are many cholesterol myths that confuse Canadians every day. Some people avoid eggs completely. Others assume high cholesterol only affects older adults. In reality, understanding what cholesterol actually does — and what truly raises it — can help you make smarter choices for your heart health. This article breaks down four of the most common cholesterol myths, backed by current health research.
What Is Cholesterol and Why Does It Matter?
Cholesterol is a waxy, fat-like substance found in every cell of your body. Your liver makes most of the cholesterol your body needs. It plays a key role in building cell membranes, protecting nerve cells in the brain, and producing hormones.
Cholesterol travels through your bloodstream attached to proteins called lipoproteins. The two main types are LDL (low-density lipoprotein) and HDL (high-density lipoprotein). LDL is often called “bad” cholesterol because high levels can build up in artery walls. HDL is called “good” cholesterol because it helps carry LDL away from the arteries.
When LDL levels stay too high for too long, it can cause atherosclerosis — a narrowing and hardening of the arteries. This raises your risk of heart attack and stroke. According to Health Canada, heart disease remains one of the leading causes of death in Canada.
Cholesterol Myths vs. Facts: The Truth About Diet
Does Dietary Cholesterol Actually Raise Your Blood Cholesterol?
Many Canadians worry about foods that contain cholesterol, known as dietary cholesterol. Foods like eggs, shrimp, and organ meats are high in dietary cholesterol. However, research now shows that dietary cholesterol has far less impact on your blood cholesterol levels than previously thought.
What matters more is the amount of saturated fat and trans fat in your diet. These fats signal your liver to produce more LDL cholesterol. Therefore, checking a food label for saturated and trans fat content is more useful than focusing on the cholesterol number alone.
If your family doctor has asked you to lower your cholesterol through diet, reducing saturated fat is the most important step. In addition, increasing your intake of fruits, vegetables, and dietary fibre can help manage your cholesterol levels naturally. The Mayo Clinic explains how diet affects cholesterol in more detail.
Cholesterol Myth #1 — Eggs Are Bad for You
This is one of the most persistent cholesterol myths in Canada and around the world. It is true that one egg contains over 200 mg of dietary cholesterol. The commonly referenced daily limit is around 300 mg. However, that does not automatically make eggs dangerous.
Here is why: when you eat more dietary cholesterol, your body compensates by producing less of its own cholesterol. This self-regulating system means that moderate egg consumption does not significantly raise blood cholesterol for most healthy people.
Eating two to three eggs per week is considered reasonable for most adults. Furthermore, eggs are an excellent source of high-quality protein and contain healthy unsaturated fats. If you have diabetes or existing heart disease, speak with your doctor or a registered dietitian about how many eggs are right for you.
What Foods Should You Actually Limit?
Instead of cutting eggs, focus on limiting foods high in saturated fat. These include fatty cuts of red meat, full-fat dairy products, butter, and processed snack foods. Trans fats, found in some commercially baked goods and fried foods, are especially harmful and should be avoided as much as possible.
Replacing saturated fats with healthy unsaturated fats — found in olive oil, avocados, nuts, and fish — can help raise your HDL and lower your LDL over time.
Cholesterol Myth #2 — Only Middle-Aged Adults Need to Worry
Many Canadians assume high cholesterol is a problem that only develops later in life. This is one of the most dangerous cholesterol myths, because it can lead to years of unhealthy habits going unchecked.
Research has shown that atherosclerosis can begin as early as age 8. Fatty deposits can start building in artery walls during childhood. By the time a person reaches middle age, significant damage may already be present.
Children with high cholesterol should follow a diet where saturated fat makes up no more than 7% of total daily calories. They should also consume no more than 200 mg of dietary cholesterol per day. Regular physical activity and fibre-rich foods are also strongly recommended for children at risk.
Should Children Be Tested for High Cholesterol?
In Canada, cholesterol screening for children is generally recommended if there is a family history of early heart disease or high cholesterol. Talk to your child’s family doctor about whether testing is appropriate. Early detection gives families the chance to make lifestyle changes before problems develop.
The World Health Organization highlights cardiovascular risk factors that can begin in childhood, reinforcing why early awareness matters.
Cholesterol Myth #3 — “Cholesterol-Free” Foods Are Always Heart-Healthy
Food packaging in Canada can be misleading. A product labelled “cholesterol-free” sounds healthy for your heart. However, this label only tells you about dietary cholesterol — not about saturated fat or trans fat content.
As noted earlier, saturated and trans fats have a much greater influence on your LDL (“bad”) cholesterol than dietary cholesterol does. A cholesterol-free cookie made with hydrogenated oil and high amounts of saturated fat can still raise your blood cholesterol significantly.
Always read the full nutrition facts panel. Look specifically at the saturated fat and trans fat rows. These numbers give you a far more accurate picture of how that food affects your cardiovascular health.
Understanding Food Labels in Canada
Health Canada requires all packaged foods to display a standardized Nutrition Facts table. The % Daily Value column shows you how much saturated and trans fat a serving contains relative to the recommended daily limit. A value of 5% or less is considered low. A value of 15% or more is considered high.
Making label reading a habit at the grocery store is a simple, practical step toward better heart health. It takes only a few seconds and can make a real difference over time.
Cholesterol Myth #4 — All Cholesterol Is Bad
Perhaps the most widespread of all cholesterol myths is the idea that cholesterol itself is the enemy. In reality, your body cannot function without it. Cholesterol is essential for producing vitamin D, building cell membranes, and creating hormones like estrogen and testosterone.
The problem is not cholesterol in general — it is an imbalance between LDL and HDL, combined with inflammation in the arteries. High LDL, especially when accompanied by low HDL, raises the risk of plaque buildup in artery walls. This is what leads to atherosclerosis and, eventually, heart attacks or strokes.
Your goal should be to maintain healthy levels of both types. Regular exercise, a balanced diet rich in fibre and healthy fats, not smoking, and maintaining a healthy weight all contribute to a better LDL-to-HDL ratio.
What Are Healthy Cholesterol Levels in Canada?
Canadian guidelines generally suggest the following targets for adults:
Total cholesterol: less than 5.2 mmol/L
LDL cholesterol: less than 3.5 mmol/L (lower if you have heart disease risk factors)
HDL cholesterol: above 1.0 mmol/L for men, above 1.3 mmol/L for women
Triglycerides: less than 1.7 mmol/L
These are general targets. Your doctor will set personalized goals based on your full health picture, including blood pressure, family history, and other risk factors.
Simple Steps to Support Healthy Cholesterol Levels
You do not need a complicated plan to start improving your cholesterol. Small, consistent changes add up over time. Here are some practical steps most Canadians can take:
Eat more fibre from oats, legumes, fruits, and vegetables
Choose healthy fats like olive oil, nuts, seeds, and fatty fish
Limit red meat, full-fat dairy, and fried foods
Aim for at least 150 minutes of moderate physical activity per week
Avoid smoking and limit alcohol intake
Maintain a healthy body weight
These lifestyle habits support your heart health and help keep both LDL and HDL in a healthy range. Even modest improvements in diet and activity level can lower your cholesterol meaningfully within a few months.
When to See a Doctor About Your Cholesterol
High cholesterol has no symptoms. You cannot feel it, and many Canadians do not know their levels are elevated until they have a blood test. This is why routine screening is so important.
Most Canadian adults should have their cholesterol checked every one to three years, starting around age 40 — or earlier if you have risk factors. Your family doctor can order a simple fasting blood test called a lipid panel. If you do not have a family doctor, a walk-in clinic can also help you get tested and interpret your results.
Talk to a healthcare provider if you have a family history of heart disease, high blood pressure, diabetes, or if you smoke. These factors combine with high cholesterol to significantly raise your cardiovascular risk. Your provincial health plan covers routine cholesterol testing, so there is no reason to delay.
If lifestyle changes are not enough, your doctor may recommend medication such as statins. This is a common and effective treatment for many Canadians. Always follow your doctor’s guidance and never stop prescribed medication without speaking to them first.
Frequently Asked Questions About Cholesterol
What are the most common cholesterol myths Canadians believe?
Some of the most common cholesterol myths include the belief that eggs are always harmful, that only older adults need to worry about cholesterol, and that all cholesterol is bad for you. In reality, dietary cholesterol has less impact on blood cholesterol than saturated and trans fats do. Understanding these cholesterol myths can help you make better choices for your heart health.
How often should Canadians get their cholesterol checked?
Most Canadian adults should have their cholesterol checked every one to three years, starting at age 40. If you have risk factors such as a family history of heart disease, diabetes, or high blood pressure, your doctor may recommend earlier or more frequent testing. A simple blood test ordered by your family doctor or at a walk-in clinic can give you a full picture of your cholesterol levels.
Can children have high cholesterol?
Yes, children can have high cholesterol, and this is one of the most overlooked cholesterol myths among parents. Research shows that atherosclerosis — the narrowing of arteries — can begin as early as age 8. Children with a family history of high cholesterol or heart disease should be screened by their family doctor.
Is dietary cholesterol the same as blood cholesterol?
No, dietary cholesterol (found in food) and blood cholesterol are not the same thing. Eating foods high in dietary cholesterol has a relatively small effect on your blood cholesterol levels for most people. Saturated fat and trans fat have a much greater impact on raising LDL, the “bad” cholesterol in your blood.
Does “cholesterol-free” on a food label mean it is heart-healthy?
Not necessarily — this is one of the most misleading cholesterol myths found on food packaging. A cholesterol-free label only means the product contains no dietary cholesterol. However, the food may still be high in saturated or trans fats, which raise LDL cholesterol in your blood. Always check the full Nutrition Facts table on Canadian food labels.
What is a healthy cholesterol level for adults in Canada?
Canadian health guidelines generally recommend a total cholesterol level below 5.2 mmol/L for adults. LDL should ideally be below 3.5 mmol/L, and HDL should be above 1.0 mmol/L for men and 1.3 mmol/L for women. Your doctor will set personalized targets based on your overall health and risk factors.
Key Takeaways
Cholesterol is not all bad. Your body needs it to function. The problem arises when LDL levels are too high and HDL levels are too low.
Dietary cholesterol is not the main culprit. Saturated fat and trans fat have a far greater effect on your blood cholesterol than the cholesterol found in food.
Eggs are not the enemy. Moderate egg consumption — two to three per week — does not significantly raise cholesterol for most healthy adults.
High cholesterol can start in childhood. Atherosclerosis can begin as early as age 8. Healthy habits for children matter more than most parents realize.
“Cholesterol-free” does not mean heart-healthy. Always check saturated and trans fat content on food labels, not just the cholesterol number.
Get tested regularly. High cholesterol has no symptoms. Ask your family doctor or visit a walk-in clinic to have your lipid levels checked as part of your routine care.
Lifestyle changes work. A diet rich in fibre, regular physical activity, and avoiding smoking can meaningfully improve your cholesterol levels over time.
