19. Avocado
Avocados are rich in monounsaturated fats, the kind that help lower LDL (bad) cholesterol while boosting heart health. Their creamy texture makes them a nutritious alternative to spreads or toppings like butter and cheese. The Mayo Clinic highlights avocados as a heart-smart ingredient worth adding to your meals. Cardiologists often recommend them on toast, salads, or as a flavorful dip in place of less healthy fats.
