Banana peels are worth using when the fruit is all gone. But there are a few things you want to consider when using the banana peels. Make sure to wash the skins before eating or putting it in a smoothie because of the pesticides used by farmers to help it grow. If you are using organic banana peels, it is okay not to wash it, but it is still your choice to clean it before eating.
Aside from eating it raw or putting your skin into a juicer or blender, you can also steam them for about 10 minutes to create a more appealing texture. You can also scrape out the inside meat of the skin to get some or most of its benefits.
