No sugar is really healthy, but the foods that contain the sugar may be. Apples for example have sugar, but they also contain fibre and lots of vitamins, making them a healthy choice. A can of soda has sugar in it too, but without any nutritional value. Whole, natural foods are the way to go.
Some foods have no sugar, some foods have added sugar, and some foods have natural sugar. Natural sugar is not unhealthy, since it's all natural, however, added sugar is unhealthy.
Probably, because most foods do anyway, like fruits and vegetables. But, the sugar would be natural, and would not be counted unhealthy.
There are no foods that do not contain both fats and sugars. However, there are foods that do not contain sugar including meat and vegetables. Fruits and vegetables are among the foods that do not contain fats.
cranberries

No, because not all white foods contain sugar so how could they turn into sugar if they contain none.
It depends on what you mean. If you mean a list, then: Sweets, crisps, chocolate, icecream, even apples! Apples have to have sugar in them to make it taste nice and sweet, but instead of sugar that we have on cereals and in tea, or while baking cakes, it's a natural healthy sugar. Also, if you mean what actually ARE sugared foods, your answer is Foods that contain sugar. :)

fruits have sugar
