The study, conducted by researchers at Penn State University and published in the Journal of Nutrition, suggests that eating one avocado a day can lower levels of low-density lipoprotein (LDL), the type of cholesterol considered to be “bad.” High levels of LDL can build up within blood vessel walls, sometimes causing a stroke or heart attack, per the Mayo Clinic.
