Lime

There is a potential issue that’s unique to many citrus: How they’re consumed, at least in the United States and Western Europe. Lemons are often either squeezed for their juice or zested for their peel. The pith and sometimes even the flesh are discarded. So it’s difficult to take a measure of lemon and say for sure what benefit you’re getting if you’re discarding one of the parts. The same goes for limes. Grapefruit and orange flesh is often consumed, along with some of the pith, however the peel is often discarded. Only kumquats amongst the citrus are commonly consumed whole: peel, pith, flesh, juice and all.
