I used to make watermelon juice. At first I only used the red part - yummy! Then the last couple of times I tried it, I put the whole thing in, including rind and seeds. It did not taste very good but I was thinking that it would be more nutritious. Am I right? I am wondering if I juiced a beet or a couple of carrots along with it, if it would compensate for the bitterness of the rind.
