11 Research-Backed Habits to Prevent Heart Disease

10. Limit alcohol and cut back on ultra-processed foods and sodium

Excessive alcohol intake and frequent consumption of ultra-processed foods are linked to higher blood pressure, worse cholesterol, and greater cardiovascular risk. Many guidelines recommend limiting alcohol to moderate amounts — if you drink at all — and reducing the intake of packaged, high-sodium foods. In daily life, this looks like choosing fresh fruit or roasted nuts over packaged namkeen, cooking more meals at home where you control the salt and oil, and using spices and citrus to build flavor instead of excess salt. Read labels for sodium content on condiments and ready-to-eat items, and swap sugary drinks for water or unsweetened chai. If you consume alcohol, set clear weekly limits and alternate alcoholic drinks with water or non-alcoholic choices. Together, these simple swaps reduce blood pressure and improve metabolic markers that protect the heart over time.
