A fresh banana gets about 75 percent of its weight from water, according to the USDA. The drying process

removes about 96 percent of this water content, making dehydrated bananas a far more concentrated source

of calories and nutrients than the source fruit. Ounce for ounce, dehydrated bananas are about four times

higher in fiber, potassium, carbohydrates, sugar and calories than the fresh variety. They're only slightly higher

in vitamin B-6, however, largely because it's a water-soluble vitamin. Dehydrated bananas are actually about

20 percent lower in vitamin C, a water-soluble vitamin that's particularly sensitive to heat.
