Heart disease remains the leading cause of death among adults over 65 in the United States. While medications and medical intervention play important roles, dietary choices are among the most powerful tools for both preventing cardiovascular disease and managing existing conditions. The evidence base here is strong, and the practical steps are more straightforward than most people realize.
The DASH and Mediterranean approaches
Two dietary patterns have the strongest clinical evidence for cardiovascular health: the DASH diet (Dietary Approaches to Stop Hypertension) and the Mediterranean diet. Both emphasize abundant vegetables, fruits, whole grains, legumes, and lean protein sources — and both significantly limit sodium, saturated fat, and processed foods. For adults over 65 managing high blood pressure, the DASH diet’s sodium limits (1,500–2,300mg/day) are particularly relevant.
Sodium and blood pressure
The majority of dietary sodium doesn’t come from the salt shaker — it comes from packaged, processed, and restaurant foods. Bread, canned soups, deli meats, and condiments are among the highest contributors. Reading labels and choosing lower-sodium alternatives in these categories can meaningfully reduce blood pressure without requiring dramatic dietary changes. Cooking at home with herbs and spices rather than salt is one of the most effective strategies.
Healthy fats, not fat elimination
Decades of low-fat dietary guidance have been substantially revised. The current evidence supports replacing saturated fats (red meat, full-fat dairy, coconut oil) with unsaturated fats — not eliminating fat entirely. Extra virgin olive oil, avocados, nuts, and fatty fish provide fats that actively support cardiovascular health by improving cholesterol ratios and reducing arterial inflammation.
Fiber’s role in heart health
Soluble fiber — found in oats, barley, legumes, apples, and citrus — binds to bile acids in the intestine and removes them from the body. Since bile acids are made from cholesterol, this process reduces LDL cholesterol. Increasing daily fiber intake by 5–10 grams per day is associated with a 5–11% reduction in LDL cholesterol, a clinically meaningful change for cardiovascular risk.
Practical daily habits
Build each meal around vegetables and legumes. Use olive oil instead of butter. Eat fatty fish twice a week. Choose whole grains over refined. Limit processed meats and packaged snack foods. Drink water, herbal tea, or black coffee rather than sugary beverages. These habits, applied consistently and without obsession, create a dietary environment that meaningfully supports heart health after 65.
