"Have a Coke in the morning." That's what an old marketing campaign from the'80s used to say. And some people who have their breakfast on the go do just that.

It appears that the amount of people who start their day with a soda-accompanied breakfast has doubled since 1990. From 7.9% to 15.1%, consumers have ordered and consumed soda pop beverages along with the most important meal of the day. And some thought gamers were addicted on pop. Well, we say it's 'bout time for a reality check folks!

So the choice of Coke over a cup of smooth, creamy coffee is rooted from the unique sensation at the back of the throat, although it's also a good bet most of the young adults like the various flavors that come in soda. Some of them believe it's a great way to get caffeine into your body, though 35 milligrams of caffeine isn't much compared to a regular cup of coffee's 75 milligrams.

Still, the choice between a Starbucks House Blend Coffee and a can of diet Coca-Cola is particularly a personal thing, but you might want to know that Pepsi has formed alliances with Starbucks Coffee Co. In fact, Coca-Cola also would be distributing iced coffee under Caribou Coffee, Co. Looks like they want to cover both sides of the market for a win-win situation.

But some people feel that Coca-Cola and Pepsi shouldn't really worry. And by the looks of the way the trend is going, we don't think they should worry either.
