A New Survey Reveals Gaps in Understanding “Bad Cholesterol” and Its ImpactCentrum Pharmacy
LDL cholesterol, often referred to as “bad cholesterol,” silently poses a grave threat to cardiovascular health. However, a recent survey conducted in 2023 by the American Heart Association (AHA) in collaboration with the Harris Poll has unveiled a concerning lack of awareness, especially among heart attack and stroke survivors. Astonishingly, 70% of these survivors were found to be unfamiliar with the term “bad cholesterol” and its implications, indicating a significant knowledge gap and an urgent need for widespread education and proactive health management.
Cholesterol is a waxy substance produced by the liver and introduced to the body through certain foods, primarily animal sources like meat and full-fat dairy products. Cholesterol travels through the bloodstream, attached to lipoproteins. The two main types of lipoproteins are high-density lipoproteins (HDL), often referred to as “good” cholesterol, and low-density lipoproteins (LDL), known as “bad” cholesterol. Together with triglycerides, these components make up your total cholesterol level.
The pervasive lack of public awareness about “bad cholesterol” and its impact on cardiovascular health is a cause for concern. Since elevated LDL cholesterol typically exhibits no symptoms, many individuals may be unaware of their risk and how to mitigate it. Elevated LDL cholesterol can lead to the formation of fatty deposits, or plaques, in the arteries, significantly increasing the risk of heart attacks and strokes. The AHA survey found that, while 75% of heart attack and stroke survivors reported having high cholesterol, but only 49% recognized the importance of lowering it. Furthermore, 47% of survivors were unaware of their LDL cholesterol levels, despite its crucial role in preventing additional cardiovascular events.
To address this issue, the AHA recommends that all adults aged 20 or older have their cholesterol checked every four to six years, provided their risk remains low. After the age of 40, healthcare professionals should use a specific calculation to assess an individual’s 10-year risk of experiencing a heart attack or stroke. Those with a history of such events may need more frequent cholesterol checks. Knowledge is undeniably a powerful tool in this context—the more you know, the better equipped you are to reduce the risk of future heart attacks and strokes.
The journey to lower cholesterol begins with mindful eating. The AHA recommends adopting a diet rich in fruits, vegetables, whole grains, poultry, fish, and nuts, while minimizing red meat and full-fat dairy. Monitoring fat intake is crucial, particularly by reducing saturated fat to less than 6% of daily calories and avoiding trans fats.
Incorporating at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking or swimming, can have a significant impact on cholesterol levels and overall cardiovascular health. For smokers, quitting is imperative. Additionally, modest weight loss of 5% to 10% can lead to improvements in cholesterol levels and overall heart health.
