What is the best diet for heart health?

The Mediterranean and DASH diets have the strongest evidence for cardiovascular protection. Both emphasize fruits, vegetables, whole grains, lean proteins, and healthy fats while limiting sodium and processed foods.

How much omega-3 do I need for heart health?

The American Heart Association recommends 2 servings of fatty fish per week (providing approximately 500mg EPA+DHA daily). For those with elevated triglycerides, higher doses (2-4g) may be recommended under medical supervision.

❤️ Heart Health

Cardiovascular disease remains the leading cause of death globally, but nutrition is one of the most powerful modifiable risk factors. Decades of research identify specific dietary patterns, nutrients, and foods that significantly reduce heart disease risk. This hub connects you to the evidence-based nutrition strategies proven to protect your heart.

Dietary Patterns for Heart Health

The DASH diet and Mediterranean diet are the two most researched and recommended dietary patterns for cardiovascular health. The PREDIMED trial demonstrated that a Mediterranean diet supplemented with olive oil or nuts reduced cardiovascular events by 30%. The DASH diet consistently lowers blood pressure by 5-11 mmHg — comparable to medication.

Key Nutrients for Cardiovascular Protection

Omega-3 fatty acids (EPA and DHA from fatty fish) reduce triglycerides and inflammation. Soluble fiber (oats, barley, legumes) lowers LDL cholesterol by 5-10%. Potassium (bananas, potatoes, leafy greens) helps regulate blood pressure. Magnesium supports healthy heart rhythm. Flavonoids from berries, dark chocolate, and tea improve endothelial function.

Foods to Limit for Heart Health

Reduce sodium to under 2,300 mg/day (ideally 1,500 mg). Limit trans fats (partially hydrogenated oils) — these are the most harmful dietary fats. Moderate saturated fat intake to less than 10% of calories. Reduce ultra-processed foods which are linked to higher cardiovascular risk independent of nutrient content.
