High cholesterol can stem from the body's own production, a diet rich in sugar, lack of physical activity, excess weight, insufficient sleep, or specific medical conditions, even when dietary fat intake is low.

A breakfast rich in soluble fiber and protein, while limiting saturated fat, sugar, and processed foods, can help maintain healthy cholesterol levels.

Consuming too much saturated fat, prolonged sitting, and insufficient sleep are three habits that can elevate bad cholesterol, impacting cardiovascular health.

Despite a healthy diet and regular exercise, I have dyslipidemia. My father also had high blood lipids from a young age. Is this condition hereditary? (Nguyen Tien Hung, 47, Hai Phong)

Eating dinner on time, limiting alcohol, and getting enough sleep help improve cholesterol and reduce the risk of cardiovascular diseases.
