Are you concerned about your heart? Eating avocados can lower blood pressure, reduce triglycerides, slow artery plaque buildup, and lower the risk of abnormal heart rhythm, heart attack, and stroke. Eating one avocado a day may lower your risk of sudden cardiac death. Most people do not get enough healthy oleic acid found in avocados. Also, avocado oil is very healthy since its fat does not oxidize with heat, avoiding toxic oils.
