Fiber factoid

The amount of fiber in a serving of food may depend on whether the food is raw or cooked. For example, a 3.5-ounce serving of plain dried prunes has 7.2 grams of fiber while a 3.5-ounce serving of stewed prunes has 6.6 grams of fiber. Why? When you stew prunes, they plump up —which means they absorb water. The water adds weight but (obviously) no fiber. So a serving of prunes-plus-water has slightly less fiber per ounce than a same-weight serving of plain dried prunes.
