Myth: All cholesterol is bad
Contrary to popular belief, not all cholesterol is harmful. In fact, your body needs cholesterol to function properly. There are two main types of cholesterol:
1. Low-density lipoprotein (LDL) cholesterol: Often referred to as "bad" cholesterol, LDL particles can accumulate in artery walls, increasing the risk of heart disease, heart attacks and strokes
2. High-density lipoprotein (HDL) cholesterol: Known as "good" cholesterol, HDL helps remove excess LDL from the bloodstream, lowering the risk of heart disease and other cardiovascular issues
Understanding the balance between these two types is crucial for maintaining heart health.
Myth: Only overweight people have high cholesterol
While being overweight or obese may increase the risk of high LDL cholesterol and low HDL cholesterol, it's not the only factor. People of all body types can have high cholesterol due to various risk factors, including:
- Family history
- Age
- Sex
- Lifestyle habits (e.g., smoking, high dietary intake of saturated and trans fats, lack of physical activity)
It's important to remember that maintaining a healthy weight is beneficial for overall health, but it doesn't guarantee optimal cholesterol levels.
Myth: Only older adults need to worry about cholesterol
While the risk of high cholesterol does increase with age, it's not exclusively an older adult concern. The American Heart Association recommends that all adults aged 20 and older should have their cholesterol (and other risk factors) checked every four to six years, assuming their risk remains low.
Although less common than in adults, children can also experience high cholesterol, especially if there's a family history of the condition.
Myth: Diet and exercise alone determine cholesterol levels
While a heart-healthy diet and regular exercise can positively impact cholesterol levels, they're not the only determining factors. Genetics, age, sex and other elements can affect cholesterol levels regardless of lifestyle habits. For example, high levels of lipoprotein(a), or Lp(a), a genetically passed down lipoprotein, can increase your risk of heart health issues.
That said, maintaining a diet rich in vegetables, fruits, whole grains and healthy fats, along with regular physical activity, can significantly benefit your overall health and cholesterol profile.
