What happened to pop?

[certainthings]

I had never heard of or seen this brand of pop before tonight. I bought it because I liked that it has zero calories, is low in sodium and has no artificial sweetener.

Then when I got home I read the back or well, the side of the can:

Recommended use or purpose: Vitamin C is an antioxidant for the maintenance of good health. Recommended dose: Adults: drink 355ml (one can) as needed. Consume up to 4 cans in 3-4 hours. Do not exceed 5 cans per day.

WTF?

Why can't it just say, "Drink"?
