High cholesterol is often a silent threat, leading to heart issues and strokes without any noticeable symptoms. This makes regular cholesterol checks crucial for individuals over 40, who should be tested every five years. Despite its critical role in health, cholesterol often feels abstract, overshadowed by more immediate concerns in our busy lives. Misleading information online can complicate the issue, such as myths about eggs being unhealthy due to their cholesterol content or fringe theories that downplay cholesterol’s significance compared to sugar in heart disease.
Manuel Mayr, a cardiologist at Imperial College London, emphasizes the importance of early prevention: “Take prevention very seriously, because if your cholesterol is high, it builds up in your arteries over decades.” To illustrate, he compares the circulatory system to a washing machine susceptible to blockages from hard water, similar to how high levels of bad cholesterol can cause cardiovascular diseases.
Understanding Cholesterol
Cholesterol is a fatty substance naturally present in our bodies, essential for producing hormones and maintaining cell structure. However, high levels pose health risks. Cholesterol in the blood exists as low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL is often labeled “bad cholesterol” due to its potential to cause artery blockages. Conversely, HDL is considered “good” as it helps metabolize LDL, maintaining balance. Numerous studies confirm that lowering LDL reduces cardiovascular events, according to Mayr.
Testing and Managing Cholesterol
The NHS recommends cholesterol checks every five years for those aged 40 to 74, and annually for individuals over 75. If there’s a family history of heart disease or symptoms like angina, a GP can provide a cholesterol test. Initial tests might provide a combined LDL and HDL number, but a detailed lipid profile is ideal for understanding HDL, LDL, and triglycerides, another blood fat that significantly impacts heart risk.

Genetics and Cholesterol
Genetics can play a major role in cholesterol levels. Some individuals may inherit familial hypercholesterolemia, a genetic disorder affecting cholesterol, which often necessitates medication beyond lifestyle changes. Identifying this condition is crucial, especially if heart issues occur at a young age within the family.
Diet, Lifestyle, and Risk Factors
Cholesterol management is part of a broader risk assessment for heart disease, considering factors like age, weight, family history, and lifestyle habits. Statins are commonly prescribed to reduce LDL levels, but lifestyle changes, such as diet and exercise, can also effectively manage cholesterol. Exercise boosts good cholesterol, while dietary adjustments, like reducing saturated fats and increasing soluble fiber intake, can lower LDL levels.
Foods that Promote Healthy Cholesterol
Healthy cholesterol levels can be supported by dietary fiber, particularly the soluble kind found in oats, beans, and lentils. These foods help prevent cholesterol absorption and promote excretion. A plant-based diet, rich in unsalted nuts, seeds, and healthy fats like those in olive oil and avocados, is recommended. Conversely, reducing saturated fats found in processed meats and high-fat dairy is important for cholesterol management.
The Truth About Dietary Cholesterol
While foods like eggs and shellfish contain cholesterol, their impact on blood cholesterol is minimal compared to saturated fats. Most people can include these foods in a balanced diet unless they have genetic conditions like familial hypercholesterolemia.
Advanced Treatment Options
For those with extremely high cholesterol, statins may not suffice. New therapies, such as PCSK9 inhibitors, offer alternative options by targeting proteins in the liver to increase LDL receptors, potentially benefiting patients with a history of heart attacks.
