You see, the trucks that deliver food and other supplies from warehouses to retail stores require diesel. And the more expensive it gets, the more it costs to eat and live.

Compared to a year ago when the average price of diesel was $3.086 a gallon, prices now are about 72 percent higher, according to data released by AAA.

"Things at the grocery store will be more expensive because of diesel," warns Patrick DeHaan, the head petroleum analyst at GasBuddy.

"Taking a cruise is going to be more expensive. Getting on a plane is going to be more expensive. Filling up is going to be more expensive."
