"I should follow better eating health rules," the Hot in Cleveland star admits to PEOPLE. "But hot dogs and Red Vines and potato chips and French fries are my favorite foods."
But White doesn't owe all of her well-being to plain luck.
"I have a two-story house and a very bad memory," she says, jokingly. "I'm up and down those stairs all the time."
All laughs aside, White, who is a spokesperson for Tide, explains, "There's no spare time, so I'm active all the time. I think that forces you to stay well. To be 90 … and still be working – that's what I wouldn't have expected. I'm the luckiest broad on two feet."
