Boost Heart Health
Guavas may benefit heart health in a variety of ways. Many experts believe that guava leaves' high quantities of antioxidants and vitamins may help protect your heart from free radical damage. Guavas' greater potassium and soluble fiber levels are also suggested to contribute to better heart health.
Guava leaf extract has also been associated with reduced blood pressure, a reduction in "bad" LDL cholesterol, and an increase in "good" HDL cholesterol. Because high blood pressure and LDL cholesterol levels are associated with an increased risk of heart disease and stroke, consuming guava leaf extract may provide beneficial advantages. Furthermore, the fruit may be beneficial to heart health. A 12-week trial of 120 adults revealed that eating ripe guava before meals reduced blood pressure by 8–9 points, reduced total cholesterol by 9.9 percent, and increased "good" HDL cholesterol by 8%.
