Here’s an activity: Get a lemon, peel it and keep a straight face while you consume the entire thing.

Could you do it? No, most likely not. How is it that a fist-size fruit has the power to make you move your muscles versus your will?

In order to endure, human beings require to consume ascorbic acid, likewise referred to as vitamin C It’s necessary to keeping much of our cells and tissues working usually. Without enough of it, human beings can get scurvy, a possibly deadly illness.

Here’s the humiliating thing: A lot of animals can make their own vitamin C, however we can’t.

Researchers can hypothesize regarding what that signal may be, however they do not understand for sure.

” The majority of the fruits that we consume are not very sour,” he stated. “Individuals do not head out of their method to bite into lemons or limes.”

Well, many people do not. For those that do, a minimum of they will not get scurvy.
