  • A Penn State University study found that eating one avocado daily for six months modestly improved sleep quality in adults with abdominal obesity, a benefit researchers didn't anticipate.
  • Avocados contain monounsaturated fats, fiber, potassium and sleep-supportive nutrients like magnesium and tryptophan, though the exact mechanisms remain unclear.
  • Poor sleep is tied to higher risks of diabetes, heart disease and cognitive decline, prompting the American Heart Association to include it in key health metrics.
  • While avocados improved diet quality and blood lipids, they didn't significantly boost overall cardiovascular health scores in the study.
  • Adding an avocado daily is an easy, flexible strategy to support sleep, but experts emphasize it's just one piece of a broader healthy lifestyle.
For years, avocados have been praised for their heart-healthy fats, fiber and essential nutrients. But a surprising new study suggests they may also hold the key to better sleep – a benefit few saw coming. Researchers at Penn State University, funded by the Avocado Nutrition Center, found that eating one avocado daily for six months led to modest but measurable improvements in sleep quality among nearly 1,000 adults with abdominal obesity. The findings, published in the Journal of the American Heart Association, caught scientists off guard. While they expected improvements in cholesterol and diet quality – both of which occurred – the sleep benefits were an unforeseen twist in a study primarily designed to assess cardiovascular health. (Related: Avocado seeds contain compounds that reduce inflammation.) Participants who consumed a daily avocado saw their sleep health scores rise by an average of 3.20 points compared to those who ate fewer than two avocados per month. Though the increase was modest, it was statistically significant, on par with improvements in diet and blood lipids. Researchers speculate that avocados' rich nutrient profile – packed with monounsaturated fats, fiber, potassium and vitamins like folate and K – may play a role in regulating sleep. Some of these nutrients, such as magnesium and tryptophan (a precursor to melatonin), are already known to influence relaxation and sleep cycles. However, the exact mechanisms remain unclear and further research is needed.

Why sleep health can't be ignored

Sleep isn't just about feeling rested – it's a cornerstone of overall health. Poor sleep has been linked to higher risks of diabetes, heart disease, depression and even cognitive decline. The American Heart Association now includes sleep as one of Life's Essential 8 metrics for cardiovascular health, recognizing its impact on blood pressure, inflammation and stress hormones. Given that nearly one-third of Americans struggle with inadequate sleep, a simple dietary tweak like adding an avocado could offer a low-effort way to nudge sleep quality in the right direction. Unlike prescription sleep aids or restrictive lifestyle changes, this intervention is easy to adopt – 88-95 percent of participants stuck with the daily avocado habit throughout the study.

The heart health paradox

Despite the sleep benefits, the study's primary goal – improving overall cardiovascular health – yielded mixed results. Using the AHA's Life's Essential 8 scoring system, researchers found no significant change in participants' total cardiovascular health scores after six months. This suggests that while avocados may enhance specific markers like diet quality and blood lipids, they aren't a magic bullet for heart health. The average participant began with a moderate score of 66 out of 100 and that number barely budged by the study's end.

Practical takeaways for everyday life

For those looking to optimize sleep, adding an avocado to daily meals is a simple, evidence-backed strategy. The study didn't specify timing or preparation methods, leaving room for flexibility – whether blended into a smoothie, mashed on toast or sliced into a salad. But experts caution against overhyping the findings. Sleep is influenced by a web of factors, from stress and screen time to bedtime routines and room environment. An avocado alone won't cure chronic insomnia, but it could be a helpful piece of the puzzle when combined with other healthy habits. This study marks the first time avocado consumption has been linked to sleep improvements, opening new avenues for nutrition research. Yet it's important to note limitations: the study focused on adults with abdominal obesity and results may not apply to the general population. Additionally, sleep data was self-reported, not measured objectively in a lab. As with many nutrition studies, correlation doesn't equal causation. While the findings are promising, they don't prove that avocados cause better sleep – only that there's an association worth exploring further. In a world where quick fixes for sleep problems are often oversold, this study offers a refreshing dose of realism. Avocados won't replace good sleep hygiene, but they might give it a subtle boost. For those already enjoying this creamy superfood, there’s now one more reason to keep it on the menu. For everyone else? It’s a reminder that sometimes, the best health solutions are hiding in plain sight – right in the produce aisle. Watch and learn about the many benefits of the avocado and its leaf.
