Polyphenols found in banana leaves are natural antioxidants, which are also found in green tea and some fruits. When hot food is served on leaves, these elements can leach into the food. This helps the body fight free radicals and can reduce the risk of cancer, heart disease and diabetes.

Antibacterial properties are also found in banana leaves. Some elements present on the surface of the leaves prevent the growth of bacteria. This reduces the risk of problems like food poisoning and food is considered safer.
