A. Fiber

  • Soluble fiber helps lower LDL ("bad") cholesterol.
  • Found in oats, beans, lentils, apples, and flaxseeds.

B. Omega-3 Fatty Acids

  • Reduce triglycerides and blood pressure.
  • Found in fatty fish (salmon, sardines), flaxseeds, and walnuts.

C. Potassium

  • Helps control blood pressure by balancing sodium levels.
  • Found in bananas, potatoes, spinach, and oranges.

D. Antioxidants

  • Combat oxidative stress and inflammation.
  • Found in berries, dark chocolate, green tea, and leafy greens.

E. Magnesium

  • Supports normal heart rhythm.

Making even small changes—like switching from white bread to whole grain, or grilling instead of frying—can significantly improve your heart health.
