The American Heart Association has released guidance emphasizing that understanding and managing cholesterol is crucial for long-term heart and brain health. With conflicting information often circulating, the organization clarifies that cholesterol itself is essential for bodily functions, but maintaining proper balance between "bad" LDL cholesterol and "good" HDL cholesterol is key to reducing cardiovascular risks.
Cholesterol is a waxy substance produced by the body for important functions like cell building and hormone production. The primary concern is elevated levels of low-density lipoprotein (LDL), which can lead to plaque buildup in arteries (atherosclerosis) and increase the risk of heart disease and stroke. Conversely, sufficient high-density lipoprotein (HDL) helps reduce this risk. "Cholesterol itself isn't the enemy – our bodies need moderate levels to function," said Dr. Roger S. Blumenthal, chair of the 2026 Dyslipidemia Guideline writing group. "The goal is balance. Healthy lifestyle habits are a powerful step in keeping LDL cholesterol in a healthy range and protecting your heart and brain over the long term."
The association distinguishes between blood cholesterol, measured through testing, and dietary cholesterol. Blood cholesterol levels are influenced by overall eating patterns, lifestyle habits, genetics, and other health factors, not just cholesterol from food. They recommend enjoying vegetables, fruits, whole grains, beans, nuts, seeds, unsaturated fats, and lean proteins while limiting ultra-processed foods high in saturated fats, added sugars, and sodium.
Adults aged 19 and older should have their cholesterol checked at least every five years via a lipid profile test, which measures HDL, LDL, triglycerides, and total blood cholesterol. Other risk factors like age, family history, and smoking status should also be considered to determine overall risk. Individuals should work with healthcare professionals to interpret results and design personalized treatment plans.
For many, healthy lifestyle habits form the foundation of cholesterol management. This includes eating a nutritious diet, getting regular physical activity, maintaining a healthy weight, ensuring adequate sleep, avoiding tobacco, and managing blood pressure and blood sugar. Some individuals may require cholesterol-lowering medications based on their risk profile, and any side effects should be discussed with a healthcare provider to adjust treatment as needed.
High cholesterol can also affect children, particularly those with inherited conditions or other risk factors. Screening is recommended for children aged 9-11 to assess risk and guide care, alongside promoting wellness habits like healthy eating, daily exercise, and sufficient sleep. These early interventions can help reduce the risk of heart disease and stroke into adulthood. For more information and resources, visit Heart.org/KnowYourCholesterol.
