The Humble Granny Smith

Updated: Jan 16

Picture the scene, you’ve just given the vocal performance of a life-time, your read was a stroke of pure genius and then… *insert tiny mouth trump*. Even the most brilliant of recordings can be de-railed by a few rogue mouth sounds. Of course, the most obvious solution is to keep hydrated to reduce those pesky noises, however, it appears that the mouth click has another adversary…


It’s a not so secret, industry secret that the humble green apple is in fact the (temporary) kryptonite of the mouth click. Many of us, myself included, accept this fact like we accept that people baking cakes on tv is surprisingly entertaining. However, I now find myself wondering why it works; what’s the secret behind the all-powerful Granny Smith?


As I am no expert on the chemical composition of apples (and a quick internet search revealed that evidently, neither is Google) I had to do a little digging. A research article published in the PLOS journal by Susana Rubido et al. reveals that chewing an apple ‘stimulate[s] an alkaline saliva flow’, due to its acidic nature. It's a common misconception that a clicky mouth is the result of excess liquid but in actual fact, the reverse is true! The saliva summoning powers of the green apple help to remove mucus and hydrate the mouth. This in turn prevents that sticky sound which is music to no one’s ears.


But does an apple a day really keep the dreaded mouth click away? Yes and no; the chemical composition of the green apple is only a temporary solution to reducing a clicky mouth. The only long lasting solution is to HYDRATE, HYDRATE, HYDRATE.



So there you have it!
