Dried fruits are dehydrated, not cooked, so they’re often found in raw food diets. They usually have more calories and natural sugars per serving because the dehydration process removes so much of the water. This reduces the volume considerably compared to the fresh form, so there are more pieces of dried fruit in the same size serving.For example, according to the United States Department of Agriculture’s National Nutrient Database, one cup of grapes has about 104 calories, and a cup of raisins has over 434 calories. This doesn’t happen because the raisin company added sugar, it happens because the raisins take up a lot less space than the fully hydrated fresh grapes. If you look at the calorie content of grapes verses raisins by pieces of fruit, then the database shows ten grapes have 34 calories and ten raisins have 16 calories.
When you look at the nutrient facts label on a package of dried fruit, you’ll probably see the amount of sugar that’s contained in the fruit. This probably isn’t added sugars in the form sucrose (table sugar) or high fructose corn syrup, unless it’s specifically listed as an added ingredient.
The sugars found in dried fruit are mostly fructose and dextrose, the same sugars that are naturally found in the fresh fruit. However, some dried fruits, like cranberries, are too tart for most people to want to eat them as a snack, so sugar or fruit juices are added to them when they’re dried. Make sure to read both the nutrient facts labels and the ingredients list before you buy the dried fruits. The ingredient list on the package will tell you whether the sugar in the dried fruit is added sugar or natural sugar.
When eating dried fruit be mindful of portion sizes as too much fructose from the fruit can be stored as fat via the liver. I would opt for no more than a handful once a day. Also consider the processes that dried fruit goes through, surely by removal of water would remove some vital waterbased vitamins that you can obtain from fruit in its wholesome natural state.
