More of the world's stinkiest foods, and how to get rid of bad breath caused by them

And you thought we'd exhausted the list. This world is positively brimming with pungent provisions and nasty-smelling nourishment, which means that our last post on the subject of the world's smelliest foods didn't cover them all - not by a long shot. Here, then, are seven more of the planet's most malodorous meals.

Pro tip: If you're wondering how to get rid of bad breath caused by any of the following foods, consider investing in specialty toothpastes, probiotics kits and alcohol-free mouthwashes.

Surströmming. A specialty of northern Sweden, this aromatic powerhouse consists of herring pickled in brine for months on end. Most connoisseurs recommend eating this stuff outdoors, since, according to one Japanese study, the smell of a newly opened can of surströmming is the most pungent food smell on Earth.

Natto. Thank Japan for this little doozy. Natto is made of soybeans that are fermented until slimy, then eaten over rice...for breakfast. Not only does it smell ungodly, but natto is so stringy that you have to learn to use chopsticks to sever the strands of gunk that stick to your lips.

Kiviak. It may sound made up, but kiviak is a traditional Inuit food from Greenland that would make even the sweetest breath smell like death. To make kiviak, you'll need to preserve a whole dead auk (a flying, penguin-like bird) inside the hollowed-out body of a seal. Don't refrigerate it! No, instead bury it and let it decompose for six months. Kiviak is often saved for wedding ceremonies or birthdays.

Fafaru. To get rid of bad breath caused by this Tahitian treat, you'll need the best specialty breath fresheners around. That's because fafaru is made by fermenting shrimp, lobster or fish in seawater.

Bokkoms. Catch a mulletfish, salt it, dry it in the sun and consume it raw. There, you've eaten the West African food bokkoms - and you probably have halitosis.

Fanazushi. This centuries-old twist on sushi involves fermenting raw fish with rice for up to four years. Fanazushi breath makes garlic breath sound positively delectable.

Century egg. We had to save the best, er, worst for last. The century egg rivals durian, surstromming and Vieux Boulogne cheese for the title of Ultimate Bad Breath Food. This Chinese dish is less-than-appetizing: Boiled eggs are rolled in a paste of clay, salt, ash, lime and rice hulls, then left at room temperature for up to three years. This makes the egg white become a gray jelly, and the yolk turns to green cream. Century eggs are said to create oral odor that smells like...well, look it up and see for yourself.
