Are raisons good for you?

I LOVE raisons, and eat a bunch everyday. i noticed that 1/4 cup of raisons has 29g of sugar. But in the ingredients, it doesnt mention any added sugar. So does thatmean all that sugar is natural sugar from the gs? does it mean that its the good type of sugar with nutrients, and not the bad refined white type of sugar? Just wondering aobut this...thanks!
