TL;DR – Quick Summary
- Daily avocado + mango improved blood vessel function by 46% vs. control group.
- Diastolic blood pressure dropped ~1.9 mmHg in male participants over 8 weeks.
- Results came from whole foods only — no supplements, no calorie changes.
A study found that daily avocado and mango improved blood vessel function and reduced diastolic blood pressure in adults with prediabetes.

Eating one avocado and one cup of mango every day for eight weeks improved blood vessel function and reduced diastolic blood pressure, according to a new study published in the Journal of the American Heart Association. The research, conducted by the Illinois Institute of Technology, followed 68 adults with prediabetes — a population at elevated cardiovascular risk.
What Researchers Measured
The study’s primary focus was flow-mediated dilation (FMD), a measure of how well blood vessels widen in response to blood flow — a key indicator of vascular health. In the avocado-and-mango group, FMD rose to 6.7% compared to 4.6% in the control group, a meaningful improvement in arterial flexibility. Diastolic blood pressure (the lower number in a reading) also fell by approximately 1.9 mmHg in male participants.
Both findings came without any change in total calorie intake or body weight, suggesting the nutrients in these fruits — not a calorie deficit — were driving the results.
The Nutrients Doing the Work
Avocados and mangoes bring a complementary mix of heart-supporting compounds. Avocados are rich in monounsaturated fats and potassium, which support healthy blood pressure and lipid balance. Mangoes add vitamin C, fiber, and additional potassium. Together, these nutrients appear to support the lining of blood vessels (the endothelium) and reduce stiffness over time.
“The study fits with what we already know about diet quality and heart health,” said registered dietitian Karen E. Todd. She noted that practical portions — roughly one-third to one-half of an avocado and half to one cup of mango a few times per week — can provide meaningful benefits without requiring the full daily amounts used in the study.
Study Context and Caveats
The research was partially funded by the National Mango Board and the Hass Avocado Board, which is worth noting when evaluating the findings. The sample was also relatively small (68 completers over 8 weeks), and the blood pressure benefits were more pronounced in male participants. Still, the study was published in a peer-reviewed journal and the results align with broader evidence on plant-based dietary patterns.
Why This Matters for Your Routine
For women focused on natural wellness, this study supports what many already intuitively know: whole foods with the right nutrient profiles can have measurable cardiovascular effects. Tossing half an avocado into a smoothie bowl or adding mango to a salsa or yogurt parfait is a genuinely low-effort way to bring more of these nutrients into daily meals — no supplements required.
