An 850-gram white truffle from northern Italy sold for 24,000 euros ($30,900) at the 10th Annual World Alba White Truffle Auction in Tokyo last night.

By weight, that’s 84 percent less than the $330,000 Macau casino billionaire Stanley Ho paid for a 1.5 kilogram truffle last year.

The auction, held simultaneously in Tokyo and the Italian towns of Grinzane Cavour and Merano, raised a combined 118,000 euros for various charities.

According to The world’s priciest food list compiled by Fortune Small Business, a CNN magazine, world’s most expensive food is Edible gold leaf.

The edible gold leaf comes with a price tag of $15,000 per pound.

No worries, like calcium and iron, gold is actually a mineral that’s safe to eat although it’s not an essential part of the human diet ^_^
