A six-month study found that eating one avocado a day was associated with lower LDL cholesterol, though researchers characterized the improvement as modest.<\/p>\n
Avocados provide monounsaturated fats, phytosterols, and fiber, all of which help explain how they can lower cholesterol.<\/p>\n
Cardiologists recommend viewing avocados as one part of a broader heart-healthy lifestyle that includes a balanced diet, regular exercise, and medication when prescribed.<\/p>\n
High cholesterol is a complex condition that\u2019s influenced by factors ranging from diet to genetics. While healthcare providers and resources like the American Heart Association<\/a> often recommend eating plenty of fruits and vegetables to manage cholesterol, new research suggests that avocado may be a valuable tool for helping lower LDL, or \u201cbad,\u201d cholesterol.<\/p>\n The study, which was published in the peer-reviewed Journal of Clinical Lipidology<\/a>, analyzed data from 786 people enrolled in the Habitual Diet and Avocado Trial, a six-month study of adults over the age of 25 with abdominal obesity. During the study, half of the participants continued their usual diet and activity levels, while the other half added one avocado a day to their diet without making any other changes to their activity or food patterns.<\/p>\n The researchers measured and collected blood samples from participants at the beginning and end of the study. While adding a daily avocado wasn\u2019t associated with changes in weight, it was linked to a 49-nanomole-per-liter reduction in LDL cholesterol. According to the researchers, that decrease could translate to about a 4% lower risk of heart disease.<\/p>\n The researchers characterized the difference as \u201cmodest.\u201d However, when it comes to reducing the risk of heart disease, doctors say even small improvements can be meaningful.<\/p>\n How do avocados help lower cholesterol?<\/p>\n There are several reasons avocados may lower LDL cholesterol, per Kirk MacNaught, MD<\/a>, a cardiologist at Tufts Medicine Lowell General Hospital. \u201cThey contain monounsaturated fats, which are a healthier fat than saturated or trans fats,\u201d he says. \u201cEating avocado with foods high in saturated or trans fats will lower \u2018bad\u2019 LDL cholesterol and help raise \u2018good\u2019 HDL cholesterol.\u201d<\/p>\n Avocados also contain phytosterols, naturally occurring plant compounds that reduce the absorption of dietary cholesterol, MacNaught explains. They\u2019re a good source of fiber, with about 5 grams of it in half of an avocado. \u201cFiber can bind to dietary cholesterol and helps clear it out of the body,\u201d MacNaught adds.<\/p>\n Avocados can help reduce cholesterol levels if they replace foods higher in saturated fat, says Gerard Daly, MD<\/a>, a cardiologist at MelroseWakefield Hospital in Massachusetts. For example, adding avocado to a meal in place of red meat or deep-fried foods.<\/p>\n The benefits of this beloved fruit extend beyond managing cholesterol. According to Catherine Weinberg, MD<\/a>, director of congenital heart disease at Northwell Health\u2019s Lenox Hill Hospital in New York City, avocados provide potassium, magnesium, fiber, and unsaturated fats, nutrients that can help support healthy blood pressure. They also contain oleic acid \u2014 a monounsaturated fatty acid that\u2019s found in olive oil too\u2014 which may help reduce inflammation and support healthy blood vessel function.<\/p>\n Related: A Daily Avocado Habit Is Linked to Better Food Choices, Study Finds<\/a><\/p>\n It\u2019s important to note that this study was funded by the Avocado Nutrition Center<\/a>, an organization that supports research on avocado nutrition. However, the organization wasn\u2019t involved in the study design, analysis, or interpretation of the data, and doctors say the results are worth considering. \u201cThese findings are encouraging and add to the growing evidence that avocados are part of a heart-healthy diet,\u201d Weinberg says.<\/p>\n Other research has linked regular avocado consumption with improved cardiovascular health too. A 2022 study published in the Journal of the American Heart Association<\/a> found that people who ate at least two servings of avocado per week had a 16% lower risk of cardiovascular disease and a 21% lower risk of coronary heart disease than those who rarely or never ate avocado. Replacing certain fat-containing foods, including butter, cheese, and processed meats, with avocado was associated with a lower risk of cardiovascular disease events.<\/p>\n Still, Weinberg cautions against viewing avocado as a solution on its own. \u201cAvocados alone are not a magic bullet,\u201d she emphasizes. \u201cYou can\u2019t just add an avocado to your daily routine and expect your cholesterol and blood pressure problems to go away.\u201d<\/p>\n A heart-healthy diet is bigger than just one ingredient<\/p>\n \u201cLowering cholesterol isn\u2019t about focusing on just one food or even one habit; it\u2019s about your overall lifestyle,\u201d says Yu-Ming Ni, MD<\/a>, a cardiologist and lipidologist at MemorialCare Heart and Vascular Institute at Orange Coast Medical Center in Fountain Valley, California. \u201cWhile dietary changes can absolutely help, they\u2019re only one piece of the puzzle.\u201d<\/p>\n Related: This Breakfast Staple May Actually Help Lower \u2018Bad\u2019 Cholesterol, Study Finds<\/a><\/p>\n
