Is cheese bad like milk is for singing voices?
You might personally be sensitive to milk and not cheese–it’s not unusual for people to have more sensitivity to milk than to cheese. Although singers describe the “drinking milk causing thickened feeling in the throat” thing as “mucus”, it’s probably actually cow’s milk sensitivity triggering gastric reflux, because dairy doesn’t produce mucus. Presumably, the reason that’s tagged as “mucus” is because it feels very similar to post-nasal drip. Many, many singers are diagnosed with gastric reflux–I don’t know if that’s because singers are more prone to it, or if it’s because singers notice the effects at lower levels of tolerance (the “thickened throat” feeling, which people who don’t have to sing might just shrug off).
