Banana Flower

Banana flower is the purple blossom of the banana plant, eaten as a vegetable in parts of Asia and rich in fiber and plant compounds. In a double-blind trial of 50 adults with prediabetes, banana biomass supplementation lowered body weight and BMI, and diastolic blood pressure also fell. Still, the evidence is limited, coming from a small study of a banana-based product, and it is very limited for blood sugar.
