The prediabetes affects millions of adults and represents a relevant risk factor for cardiovascular diseases. In this context, the search for simple dietary strategies has gained importance in prevention and metabolic management.

A recent study from the Nutrition Research Center at the Illinois Institute of Technology, published in early 2026 according to Fox News Digitalindicates that consume an avocado and a cup of mango daily can improve heart function and blood pressure in adults with prediabetes in just eight weeks.

The research, carried out in Chicago with 82 diagnosed adults, showed that Those who incorporated both fruits showed improvements in the function of the blood vessels and in diastolic blood pressureespecially in men, compared to a control group with the same caloric intake but without these fruits.

The researchers pointed out Fox News Digital that “Adding one avocado and one cup of mango per day reduces dietary risk factors and improves vascular health indices, constituting a practical and modifiable strategy”.

The intervention was simple and accessible, with benefits observed in indirect indicators of cardiac health, mainly in vascular function and diastolic blood pressure.

Nutritional benefits of avocado and mango

Specialists consulted by Fox News Digital They highlighted that the avocado is rich in monounsaturated fats, fiber and potassiumnutrients that help maintain healthy cholesterol levels and promote satiety. Mango, meanwhile, provides vitamin C, antioxidants and an additional amount of fiber.contributing to cardiovascular health and the optimal functioning of the immune system.

Michelle Routhenstein, a dietitian specializing in preventive cardiology, said incorporating a wide variety of whole fruits and vegetables is essential for a healthy diet. In Routhenstein’s words, such consumption “It can provide polyphenols and other micronutrients that promote cardiovascular health.”

“Each fruit and vegetable can offer different protective benefits for the heart”added the expert to Fox News Digital.

The integration of these fruits into the daily diet is versatile, whether in smoothies, sauces, salads or toasts, adding flavor and nutritional value to the usual menus and facilitating adherence to a balanced diet.

Recommendations and warnings from specialists

The potential benefit of incorporating avocado and mango is relevant for those with prediabetes, although each individual case must be considered. According to Routhenstein, adding these foods can help improve vascular health goals if done by replacing less nutritionally dense products and adjusting to individual calorie and carbohydrate needs.

The expert warned that those who need to limit potassium, such as People with kidney problems should consult a health professional before modifying their diet in this regard. On the other hand, Dr. Philip Ovadia, cardiothoracic surgeon, emphasized Fox News Digital the importance of assessing the general quality of the diet.

“The avocado is an excellent whole food: healthy fats, fiber and very little sugar. Mango is more problematic for someone with prediabetes because it has a high natural sugar content,” he emphasized.

In that sense, Ovadia stressed that the main focus for people with prediabetes should be improving metabolic health and reducing the consumption of sugar and processed foods, beyond increasing the intake of these specific fruits.

Limits and context of the study

The authors themselves and consulted experts emphasized several limitations of the research. The sample was only 82 participants and the intervention It was limited to eight weeks, so the long-term impact cannot be established.

Likewise, the data collected correspond to indirect markers, such as the function of blood vessels, without directly evaluating clinical outcomes such as the incidence of heart attacks or the development of diabetes.

Furthermore, as pointed out Fox News Digitalthe study was financed by entities linked to the avocado and mango industry. Experts such as Routhenstein and Ovadia advise interpreting the findings with caution and emphasize the convenience of consulting additional sources before making substantial changes to the diet.

Both the study and the specialists consulted by Fox News Digital agree that the basis of cardiovascular health comes from a diet focused on natural, whole and varied productsrelegating ultra-processed foods and added sugars to a secondary place in the daily diet.
