New research suggests that regularly eating two common fruits—avocado and mango—may help support heart health, particularly for people with prediabetes. Prediabetes is a condition in which blood sugar levels are higher than normal but not yet high enough to be classified as type 2 diabetes. It is common in many countries and is associated with an increased risk of diabetes and cardiovascular disease.

Researchers explored whether simple dietary changes could improve markers linked to heart health. The findings suggest that adding specific nutrient-rich fruits to a daily diet may provide measurable benefits for vascular function.

Avocado And Mango Linked To Heart Health Benefits

To examine the potential effects of these fruits, researchers followed 82 adults diagnosed with prediabetes for eight weeks.

Participants were divided into two groups. One group consumed one cup of mango and one cup of avocado every day. The second group consumed other foods that provided a similar number of calories but did not include these fruits.

Both groups were provided with prepared meals such as breakfasts, snacks, and either lunch or dinner. Participants were also allowed to prepare some meals themselves at home.

Before and after the eight-week study period, researchers measured flow-mediated dilation, a test that evaluates how well blood vessels relax and expand in response to increased blood flow. This measurement reflects the health of the endothelium, the inner lining of blood vessels.

Participants who consumed mango and avocado experienced an average improvement of about one percent in flow-mediated dilation. In contrast, the control group showed a slight decline.

Even small improvements in this measure may be meaningful. Previous research has suggested that a one percent increase in flow-mediated dilation may correspond with a lower risk of cardiovascular events such as heart attack or stroke.

Men in the avocado and mango group also experienced a small reduction in diastolic blood pressure, which is the lower number in a blood pressure reading. Meanwhile, diastolic blood pressure slightly increased in the comparison group.

Participants who regularly ate mango and avocado also consumed greater amounts of dietary fiber, vitamin C, and beneficial fats overall.

How Mango And Avocado Could Affect Blood Pressure

Although the results are promising, the study had several limitations.

The study was relatively small and lasted only eight weeks. Additionally, all participants had prediabetes, meaning the results may not necessarily apply to people without this condition.

Researchers also measured early markers of cardiovascular health rather than long-term outcomes such as heart attack or stroke.

Despite these limitations, scientists have proposed several possible explanations for the observed benefits.

Nutrient Content
Both mango and avocado contain nutrients associated with cardiovascular health. For example, vitamin C and potassium may help support normal blood vessel function and healthy blood pressure.

Phytochemicals
These fruits also provide phytochemicals, plant compounds that may help protect the inner lining of blood vessels from damage.

Healthy Fats
Avocados contain monounsaturated fats, which are considered heart-healthy fats. These fats may help the body absorb certain plant compounds more effectively.

Researchers suggest that the combination of nutrients and plant compounds in mango and avocado may work together to support vascular health.

What This Means For Everyday Eating

Although the study focused specifically on individuals with prediabetes, the findings highlight a broader principle about nutrition and heart health.

Improving cardiovascular health does not always require major dietary changes. Instead, consistent small adjustments—such as adding more fruits and whole foods to meals—may provide meaningful benefits over time.

Rather than relying on a single “superfood,” a balanced diet rich in fruits, vegetables, whole grains, and healthy fats is generally recommended for heart health.

Mango and avocado are widely available fruits that are already common in many cuisines around the world. Because they are nutritious and versatile, they can easily be incorporated into daily meals.

Simple Ways To Add Mango And Avocado To Your Diet

There are many easy ways to include these fruits in everyday meals.

Add Them To Yogurt
Mix diced mango and avocado into Greek yogurt for a nutrient-rich breakfast or snack.

Blend Into Smoothies
Both fruits blend well into smoothies and add natural creaminess and sweetness.

Use In Fresh Salsa
Mango and avocado can be combined with ingredients such as tomatoes, onions, and lime juice to create a flavorful salsa.

Top Salads
Slices of mango and avocado add texture and healthy nutrients to green salads.

Serve With Egg Dishes
These fruits can also be served alongside eggs for a balanced and satisfying meal.

Including a variety of fruits in the diet may help support overall health while adding flavor and nutrients to daily meals.
