Juicing Melons

[sport]

When I get organic watermelons I juice the skin because I have read that there are lot nutrients there.
Does anyone know if the same applies to other melons. I do not want to trow the skin out if there is goodness in it but I do not want to go to the trouble of juicing and drinking something that may not be very nice if there is not a worthwhile result.

I've heard the skin is beneficial for your kidneys.

I've heard the skin is beneficial for your kidneys.
But is this just for watermelons or does it apply to the others.
