What's Australia's worst fast food?

An investigation by consumer watchdog Choice has put the country’s takeaway choices under the microscope.

The Hungry Jack's Ultimate Double Whopper has been revealed as the unhealthiest option in a sample of major food outlets.

With 80g of fat, 2386mg of sodium and 5085 kilojoules, the burger accounts for almost 60 per cent of an adult's recommended daily kilojoule intake.

Choice sampled food from Hungry Jack's, McDonald's, KFC, Pizza Hut, Domino's, Subway, Red Rooster and Oporto. Of these takeaway outlets, Hungry Jacks was also given the silver medal for the second-most unhealthy menu option with its Angry Angus double burger, which contains 52.1 grams of fat, 1.7 grams of sodium and 3276 kilojoules.

It takes four hours of constant house cleaning to burn off a McDonald's Double Quarter Pounder, a 1 1/2-hour jog for an Ultimate Double Whopper, and an hour of cycling for KFC's Wicked Wings Snack Box.

Health conscious consumers would be better off with Red Rooster's Free Range Garden salad, which the report found had the lowest count at 479Kj.

But as Choice spokeswoman Ingrid Just says, "Let’s face it, not many of us go to a fast food outlet for a salad."

"When you add chips and a soft drink to something like the Ultimate Double Whopper, you're consuming a day's worth of kilojoules in one meal."

"It's a safe bet not many of us would realise that. We need better information about the fast food were buying."

Choice is campaigning for all key fast-food outlets across Australia to be forced to declare kilojoules on their menus to fight obesity.

Hungry Jack's said it already gave detailed nutritional information in stores and online, and supported the mandatory rollout of kilojoule content menu boards.

Suggested total daily intake for an average adult is 8700Kj, 70g fat and 2300mg of sodium.
