So this morning I did some saliva ph testing while eating some Valencia oranges. I knew the juicy part was acidic in the mouth but I was surprised to see the pith is alkaline. I was already a fan of eating the pith for its nutrients but this makes it seem like we are supposed to eat the pith.
I removed most of the zest from the oranges using a peeler so I don't know if zest tends to be acidic or basic. Also the test strips that say juice+pith were after a good bit of chewing and much of the juice having been swallowed.
The coconut butter is there because I happened to test it too. Looks like it would make a good neutralizer as well.
