For those seeking simple, accessible ways to support heart health, recent research offers a surprisingly delicious prescription: add an avocado and a cup of mango to your daily diet. A recent study published in the Journal of the American Heart Association suggests that incorporating these two fruits can lead to measurable improvements in cardiovascular function, particularly for individuals with prediabetes.
The findings, which focused on flow-mediated dilation – a key indicator of artery health – and blood pressure, offer a compelling argument for the power of “food as medicine.” Researchers found that even without significant lifestyle changes like increased exercise or weight loss, the addition of avocado and mango yielded positive results. This is particularly encouraging news for the millions of Americans living with prediabetes, a condition that significantly elevates the risk of heart disease.
The study, conducted by researchers at the Illinois Institute of Technology, involved adults with prediabetes who were divided into two groups. One group, designated the Avocado-Mango (AM) group, consumed one medium Hass avocado and one cup of fresh mango daily for eight weeks. The other group maintained a similar caloric intake but substituted the avocado and mango with carbohydrate-based foods. The results revealed a notable difference in arterial function between the two groups. The AM group experienced a 6.7% increase in flow-mediated dilation, while the control group saw a decline to 4.6%.
A Boost for Blood Vessels and Blood Pressure
Flow-mediated dilation, or FMD, is a measure of how well arteries expand and contract in response to increased blood flow. Healthy arteries exhibit greater flexibility, while those that are stiff or damaged struggle to adapt. The improvement observed in the AM group suggests a positive impact on vascular health. Beyond arterial function, the study likewise revealed improvements in diastolic blood pressure, particularly among men. Men in the control group experienced an average increase of 5 points (mmHg) in central blood pressure, while those consuming avocado and mango saw a reduction of approximately 1.9 points.
The Nutritional Synergy of Avocado and Mango
While seemingly an unlikely pairing, avocados and mangoes offer a complementary nutritional profile that may explain their combined benefits. Avocados are rich in heart-healthy monounsaturated fats, which can help support healthy cholesterol levels, and fiber, which promotes digestive health and satiety. They also provide essential nutrients like potassium, vitamins E, C, K, and several B vitamins, as well as antioxidants like lutein and zeaxanthin.
Mangoes, are an excellent source of vitamin C, which supports immunity and iron absorption, and vitamin A, crucial for eye health and skin integrity. They also contain antioxidants like beta-carotene and polyphenols, and offer potassium and folate, all contributing to overall wellness. Together, the AM group saw increases in their intake of fiber, vitamin C, and monounsaturated fats.
Beyond Cardiovascular Benefits
Interestingly, the study also indicated improvements in select kidney function markers within the avocado-mango group, suggesting potential benefits beyond cardiovascular health. Dr. Britt Burton-Freeman, the study’s principal investigator and a professor at Illinois Institute of Technology, emphasized the significance of these findings. “This research reinforces the power of food-first strategies to help reduce cardiovascular disease risk, particularly in vulnerable populations like those with prediabetes,” she said.
Modest Changes, Meaningful Impact
One of the most compelling aspects of this research is that participants were not asked to build drastic lifestyle changes. They didn’t need to lose weight, increase their physical activity, or adhere to strict dietary rules. The sole intervention – the addition of avocado and mango – proved sufficient to elicit positive changes. As Dr. Burton-Freeman noted, “It’s an encouraging message: small, nutrient-dense additions – like incorporating avocado and mango into meals and snacks – may support heart health without the need for strict rules or major dietary overhauls.”
Cardiovascular disease remains the leading cause of death globally, and individuals with prediabetes face an elevated risk. While diet has long been recognized as a cornerstone of heart health, pinpointing specific foods and their effects can be challenging. This study provides concrete evidence supporting the inclusion of avocados and mangoes as part of a heart-healthy dietary pattern.
While an avocado and a cup of mango each day are not a substitute for comprehensive medical care or a well-rounded lifestyle, they may offer a simple, accessible, and enjoyable way to support blood vessel health and help manage blood pressure. The full study is available in the Journal of the American Heart Association.

Researchers will continue to investigate the long-term effects of avocado and mango consumption on cardiovascular health and explore the potential mechanisms underlying these benefits. Further studies are planned to assess the impact of these fruits on other risk factors for heart disease, such as cholesterol levels and inflammation.
