During a lecture at a recent conference on obesity the well-known nutrition expert blasted gas station fast food, newspaper VG reports.

"I believe that the sale of hot dogs and candy at gas stations should be forbidden. They should sell gas and auto parts," Norum said.

"When you go into a gas station you can hardly do what you came for, namely buy gas, because there is a huge queue for sausages," Norum said.

"They have turned gas stations in to unhealthy food stations," Norum told VG, and admits his suggested ban is crazy. He just wants to draw attention to the need for serious debate.

Health Minister Dagfinn Hoeybraaten welcomes the debate and agrees that making the hot dog, Norway's most accessible cheap meal, harder to buy is not likely.

"Fast food at gas stations and in kiosks is a part of our lifestyle. We have to work on getting healthy food more easily available," Hoeybraaten said.

Norum is right about the crowds for Norwegian hot dogs. Shell is the market leader and sells 15 million sausages a year, and according to information chief Per Anders Owren, only one in five of their customers comes in to buy gasoline.

Owren was not impressed with the idea of trying to influence Shell's product line.

"It's a bit Bulgaria 20 years ago," Owren said.

The total hot dog market in Norway is 39,000 tons a year, with 9,000 tons being sold in gas stations and fast food outlets.
