I kinda thought this sort of incentive for unhealthy behaviour was illegal now

Turn Those Empty Calories Into Double XP with Modern Warfare 3 Mountain Dew & Doritos
Snack enthusiasts will have a powerful advantage over their non-snacking multiplayer rivals in Call of Duty: Modern Warfare 3, thanks to Doritos and Mountain Dew's "Rank Up Your Game" scheme. It turns the consumption of nacho cheese flavored chips and carbonated beverages into cold, hard experience points—twice as many, 15 minutes at a time.
The people who harvest the sweet, refreshing nectar from mountaintops and stuff it in a bottle are giving Call of Duty fans a "Game Fuel" to call their own this fall. Not only will it (presumably) quench thirsts and capably wash down tortilla chips of the nacho cheese and cool ranch varieties, it will give Modern Warfare 3 players a "double XP" boost if they redeem unique codes from Mountain Dew and Doritos products.
