For more than half a year, 969 adults with abdominal obesity took on a simple daily habit: eating one large avocado. What happened next caught even the scientists by surprise. Beyond expected benefits to heart health, this green fruit brought an unexpected perk—better sleep quality.

The participants, all aged 25 and older, were divided into two groups. One group made a point to eat one large avocado every day for 26 weeks. The other group maintained their usual diet, eating avocado less than twice a month. Researchers hoped to observe improvements in cardiovascular health, given avocado’s reputation for heart-friendly nutrients.
Indeed, those eating the avocado regularly saw improvements in key blood lipids such as cholesterol and triglycerides, suggesting a positive impact on heart health. But what truly stood out was how significantly their sleep quality improved—a surprise finding that the researchers are eager to investigate further.

Avocados are packed with a potent mix of nutrients that likely create this soothing effect. The fruit is rich in monounsaturated fats, dietary fiber, potassium, folate, vitamin K, copper, and pantothenic acid. Each of these plays a role in regulating bodily functions related to rest and recovery.
Dr. Kristina Petersen from Penn State University, who led the study published in the Journal of the American Heart Association, highlights the fruit’s nutrient richness. “While avocado isn’t a magic cure, its dense nutritional value supports many health aspects, including sleep quality,” she says.
This connection between food and sleep opens new possibilities for how diet might be a natural tool to enhance rest—especially in a society where many struggle with poor sleeping habits.
How to enjoy avocado without the extra calories
Though avocados are healthful, they are also energy-dense, meaning they pack a lot of calories in a relatively small serving. Experts caution against overindulging to avoid unwanted weight gain. The sweet spot seems to be about one whole avocado per day.
Anyone who has tried adding avocado to meals knows it can make dishes feel indulgent and satisfying. From creamy spreads on toast to salad boosters, it’s an easy ingredient to include. Personally, after a few weeks of consistent avocado eating, I noticed my afternoon cravings eased and my sleep felt deeper and more restful. It made me rethink the role of diet in daily well-being.
Beyond improving lipid profiles and sleep, avocado has also been associated with lowering “bad” LDL cholesterol, reducing belly fat in women, and lowering the risk of type 2 diabetes. Small changes like these can add up to big health wins over time.
