Susie Burrell is considered one of the top dietitian's in the world so when she gives advice people listen. Susie says forget the apple a day, one of the best things you do for your body is eat a banana peel. “Specifically, you will increase your overall fiber content by at least ten per cent as a lot of dietary fiber can be found in the skin of the banana. You will get almost 20 percent more vitamin B6 and almost 20 percent more vitamin C and you will boost both your potassium and magnesium intake. Specifically bananas with bright yellow skins have a higher proportion of antioxidants associated with anti-cancer effects while green skins (less ripe bananas) are particularly rich in the amino acid tryptophan which is associated with good sleep quality. Green banana skins are also rich in resistance starch, the special type of fiber known to benefit gut health. As these skins are much tougher, they are definitely best consumed after boiling to soften the skins.”
She offers recipes on how to prepare banana peels for consumption on her blog.
