Scientists Have Identified An Unexpected Benefit Of Avocados For Heart Health

Even just one piece of fruit a week is associated with a reduced risk of cardiovascular disease.
If you like to start your day with avocado toast, you might wonder whether it’s healthy to eat this fruit every day. Avocados do contain a lot of fat, but a significant portion of that fat is monounsaturated, which is considered beneficial for heart health. In addition, avocados are rich in fiber, vitamins, minerals, and antioxidants.
This is reported by goodhousekeeping.com.
Santa Barbara-based nutritionist Jerry French calls the avocado “a healthy food with many benefits.” This fruit is grown in warm regions, including Florida, Mexico, and California. Although there are more than 500 varieties of avocados, the Hass variety is the most commonly found in stores.
One peeled avocado contains about 322 calories, 29 grams of fat, 14 grams of fiber, 17 grams of carbohydrates, and 4 grams of protein. For women, the recommended daily intake of fiber is 21–25 grams, so a single avocado provides more than half of that amount.
However, the high fat content does not automatically make avocados unhealthy. Most of the fats in avocados are monounsaturated, which are considered beneficial, particularly for the cardiovascular system.
Researchers at the T. H. Chan School of Public Health at Harvard found that people who consumed an amount of avocado equivalent to one fruit per week had a 16% lower risk of cardiovascular disease and a 21% lower risk of ischemic heart disease compared to those who did not eat avocados at all.
The study also showed that replacing half a serving of margarine, butter, eggs, yogurt, cheese, or processed meat with the same amount of avocado every day was associated with a 16–22% reduction in the risk of cardiovascular disease.
Avocados also have a low glycemic index, so they may be suitable for people who monitor their blood sugar levels. In a 2023 study, people who ate avocados two days before the start of the study had a 20% lower risk of developing diabetes over the next six years compared to those who did not eat them. Among participants with prediabetes, avocado consumption prior to the start of the study was associated with a 31% lower risk of developing diabetes over the same six-year period.
Avocados contain folate, vitamins B6, C, and K, manganese, copper, zinc, sodium, potassium, phosphorus, magnesium, iron, and calcium. The fruit is also rich in carotenoids. Among them is beta-carotene—an antioxidant linked to protection against certain types of cancer and cardiovascular diseases. Lutein and zeaxanthin are important for eye health and may help prevent eye diseases, including age-related macular degeneration.
According to French, “Practically anyone can eat an avocado every day—just not three avocados a day.” The dietitian advises using the fruit as a substitute for foods with lower nutritional value that people regularly consume.
However, eating avocados every day isn’t suitable for everyone without restrictions. Nutritionist Brooke Levenstein notes that people with kidney disease may need to monitor their potassium intake. For those following a low-fat or low-calorie diet, it’s also important to watch portion sizes.
There are many ways to eat avocados. A ripe avocado should give slightly when pressed, and its skin usually turns dark green. If an avocado is too firm, you can place it in a paper bag and leave it on a windowsill or countertop for a few days.
You can add avocado to salads after drizzling it with lemon juice and seasoning it with salt and pepper. French prefers to mix diced avocado with beans, corn, and tomatoes. Another simple option is to mash the avocado and spread it on bread, adding lemon pepper, garlic salt, or Cajun seasoning.
Avocado can also be added to smoothies along with leafy greens, a small amount of fruit juice, and water. It can be grilled and served with chicken or baked with a filling of ground meat and cheese.
It’s important to consider not only the avocado itself but also the foods it’s eaten with. French warns that “the problem might be what it’s paired with.” For example, a healthy avocado salad ceases to be such a good choice if you douse it with a large amount of processed dressing. The same goes for guacamole: the avocado itself may be healthy, but overeating chips with it every day changes the overall picture of your diet.
Thus, experts and studies agree that you can eat avocados every day, but portion size matters. Levenstein advises sticking to about one-third or half an avocado to reap the benefits of the fruit without unnecessarily increasing the number of calories and fats in your diet.
