Prepare to hear a ghost story about one of the spookiest devils around — processed sugar.

Tom Brady and Gisele Bündchen, who have famously instigated a restrictive diet for the whole family, deflated their kids' dreams that maybe they could enjoy their trick or treating candy. How'd they do that? Well, by actually letting them taste it.

While Brady really, really likes organic candy, apparently the neighbors elected to give away your typical Reese's and candy corn and it didn't go over so well.

“We don’t really have that a kind of sugar in our house,” Bündchen told People. “I let them try one (piece), but they really only had one bite and then they didn’t want it anymore.”

Benjamin, 6, and Vivian, 3, live in a household where even tomatoes are bad news and strawberries are pure mythology, so normal candy was undoubtably a shock to their system.

Fortunately, other kids were able to benefit from the Brady-Bündchens' peculiar palates.

“It’s a little different kind of sweets, so they’re not used to it,” she said. “I said to them, ‘You know, there are so many kids that don’t get candy and you guys got so many, some kids don’t even get one!' And they’re like, ‘Oh mom, OK you can give it to them if they don’t get any.’"

Hopefully the kiddos got to go trick or treating at the farmer's market to make up for it.
