A new study from researchers in Illinois, led by Dr. Britt Burton-Freeman of the Illinois Institute of Technology, has found that incorporating one cup of avocado and one cup of mango into the daily diet can significantly improve vascular health in prediabetic adults. Over eight weeks, participants on this avocado-mango diet experienced a 6.7 percent increase in flow-mediated dilation, while those on a control diet saw a 4.6 percent decrease, highlighting the potential benefits of these fruits in combating cardiovascular disease. The researchers attribute these improvements to the fiber, vitamin C, and unsaturated fats found in avocados and mangoes, which are believed to play a crucial role in enhancing heart health.
