IU said, "I don't do anything that's bad for my throat. I don't like the smell of caffeine (coffee) or cigarettes. I don't like talking loudly either."
She continued, "I don't have any interest in carbonated drinks, and I rarely drink alcohol. I only drink (alcohol) on happy occasions, only an amount that won't hurt my throat."

IU explained that she tries to minimize doing bad things for her throat, rather than doing something good.
