4. Avocado

This creamy fruit has become the unofficial symbol of healthy eating, and the science actually backs it up. Avocados are rich in monounsaturated fats, the kind that raise your HDL (“good”) cholesterol while nudging LDL down at the same time. They’re also loaded with potassium, which helps regulate blood pressure even more effectively than the potassium in a banana. Half an avocado a few times a week on toast, in a salad, or blended into a smoothie is enough to start seeing the benefit. It’s proof that protecting your heart doesn’t have to taste like punishment.
