Food and drink can affect the voice on two levels.
One is at the vocal fold level, while the second affects the stomach and body as a whole.
Food/Drink can affect the vocal folds very quickly and acutely, like smoking or drinking alcohol. But you also want to avoid foods that will increase the PH of your stomach which makes it more acidic
Avoid sugar, dairy and grains right before singing. You should also drink lots of water or sparkling water if you’re craving an alcoholic beverage right before you sing.
