Avocado and Mango Combination Improves Heart Health in Weeks

New research indicates that a daily combination of avocado and mango may improve key markers of cardiovascular health in adults with prediabetes. A study published in the Journal of the American Heart Association found that incorporating these two fruits into a daily diet for eight weeks led to improved vascular function and blood pressure readings.

The study was conducted by researchers at the Illinois Institute of Technology’s Center for Nutrition Research in Chicago. The team focused on adults with prediabetes, a condition affecting approximately 98 million Americans, to determine if a specific dietary intervention could reduce cardiovascular risk factors.

Study Design and Findings

The research involved 82 adults with prediabetes who followed partially structured meal plans. One group followed an Avocado-Mango (AM) diet, which required the daily consumption of one medium Hass avocado and one cup of fresh mango. A control group followed a similar diet but replaced these fruits with calorically comparable carbohydrate-based foods.

After eight weeks, the researchers measured flow-mediated dilation (FMD), which is used to assess how well blood vessels expand as blood flows through them. This is a key indicator of endothelial function and overall blood vessel health.

Participants on the AM diet showed a significant increase in FMD to 6.7%. In contrast, the control group experienced a decline in FMD to 4.6%.

the study found improvements in diastolic blood pressure, which is the bottom number in a standard blood pressure measurement. These improvements in blood pressure were particularly notable among male participants.

Nutritional Components

Experts suggest that the benefits derived from this pairing stem from the complementary nutrient profiles of the two fruits. Avocados are rich in potassium, fiber, and monounsaturated fats, which are known to support satiety and healthy cholesterol levels.

Mangos contribute antioxidants, vitamin C, and additional fiber to the diet. Together, these nutrients work to support healthy circulation and reduce the workload on the heart, which facilitates the transport of oxygen-rich blood to vital organs.

Adding 1 avocado and 1 cup of mango per day reduces dietary risk factors and improves vascular health indices, serving as a practical strategy toward improving cardiovascular outcomes through a modifiable lifestyle intervention

Clinical Implications for Prediabetes

For individuals with prediabetes, managing cardiovascular health is critical as the condition often coincides with other metabolic risk factors. The researchers noted that the improvement in vascular function serves as a practical strategy for improving long-term heart health outcomes through modifiable lifestyle changes.

By improving the elasticity and function of blood vessels, the intervention may help reduce the risk of complications associated with cardiovascular disease, such as heart attack or stroke.

The findings suggest that simple, food-based interventions can produce measurable physiological changes in a relatively short timeframe, with significant results observed within the eight-week study period.
