D&D 5E - RAW: Using Purify Food and Drink to cure a party member?

Okay, so I laughed...but then I thought about it. RAW, the player might have a valid argument. Here is the very short description of purify food and drink: "All nonmagical food and drink within a 5-foot-radius sphere centered on a point of your choice within range is purified and rendered free of poison and disease."
