With just 100 days to go until the August games, a directive that the Australian Olympic team must source all food supplies within China has been dubbed the "vegemite ban" by local media.
Vegemite, a dark, savoury spread made from yeast extract, is not to everyone's taste but it is a crucial ingredient in most Australians' kitchens, used widely on toast, in sandwiches, and as a stock for cooking.
Australian Olympic team nutritionist Professor Louise Burke told the Herald Sun newspaper that having such home-grown products is crucial to the athletes' peace of mind.
The Vegemite ban
"A lot of the food we are taking is not readily available in China. They do not tend to make cereals ... or the muesli bars that our athletes love," Burke said. "We would like to take these products because they help our athletes feel at home."
The Australian Olympic Committee said it was working on getting a green light for the goods.
Salty-tasting Vegemite, which is said to be a good source of vitamins, has grown into an iconic food in Australia since it was invented Melbourne in the 1920s.
Made from yeast left over from beer brewing process, it is found in nine out of 10 Australian pantries.
